Electronic amplifiers are board level components for amplifying voltage, current or power. Various types include linear, log and op amps.
Amplifier and Linear Devices Categories
Active Band Pass Filters (23 suppliers)
Active band pass filters are used to attenuate frequencies below and above a range of frequencies (i.e., the bandwidth or passband of the filter).
Active Band Reject Filters (8 suppliers)
Active band reject filters are tuned circuits that prevent the passage of signals within a specified band of frequencies. These devices are also known as bandstop or notch filters.
Active Filters (51 suppliers)
Active filters are electronic filters that use active components such as voltage amplifiers or operational amplifiers. The amplifier shapes and stabilizes the behavior of the filter, and serves as a buffer interface to the driven component.
Active High Pass Filters (11 suppliers)
Active high pass filters pass signals from high frequencies and reject signals from low frequencies.
Active Low Pass Filters (25 suppliers)
Active low pass filters pass signals from low frequencies and reject signals from high frequencies.
Amplifier and Comparator Chips (321 suppliers)
Amplifier and comparator chips are board-level components for amplifying voltage, current, or power.
Analog Comparators (84 suppliers)
Analog comparators are amplifiers that compare the magnitude of voltages at two inputs. An analog comparator is an operational amplifier with negative feedback removed, and with no feedback and very high gain, the output voltage goes to one extreme to the other.
Audio Amplifier Chips (86 suppliers)
Audio amplifiers are used in circuits and systems to process audio signals.
Buffer Amplifiers (52 suppliers)
Buffer amplifiers have unity gain. They are used to match impedances between two devices, or as isolators.
Crystal Filters (52 suppliers)
Crystal filters are electronic filters that use monolithic crystals.
Current Sense Amplifiers (45 suppliers)
Current sense amplifiers are integrated circuits with operational amplifiers and sense resistors that are used in measuring the amplitude and direction of current in circuits.
Differential Amplifier Chips (54 suppliers)
Differential amplifier chips are designed to amplify the difference between two input signals. They can amplify a small difference between two signal levels and ignore any common level shared between them.
IC Analog Crosspoint Switches (34 suppliers)
Crosspoint switches are used for routing high speed signals such as video and audio signals.
IC Analog Multiplexers (83 suppliers)
Analog multiplexers have sets of switches that connect several analog inputs to a common analog output, allowing a single analog-to-digital converter (ADC) to sample data from multiple inputs.
IC Analog Switches (107 suppliers)
IC analog switches are integrated circuits (ICs) that allow electric current to flow when closed and prevent current from flowing when open. They are often used to interface analog signals to digital controllers.
IC Electronic Filters (201 suppliers)
IC electronic filters are frequency-selective circuits that consist of devices such resistors, capacitors, inductors, transistors, or operational amplifiers coupled with reactive components.
IC Linear Voltage Regulators (146 suppliers)
Integrated circuit (IC) linear voltage regulators use voltage-controlled sources to force a fixed voltage to appear at their output terminal.
IC Switching Voltage Regulators (117 suppliers)
IC switching voltage regulators are integrated circuits (ICs) that store energy in an inductor, transformer, or capacitor and then use this storage device to transfer energy from the input to the output in discrete packets over a low-resistance switch.
IC Voltage Regulators (322 suppliers)
IC voltage regulators are three-terminal devices that provide a constant DC output voltage that is independent of the input voltage, output load current, and temperature. IC voltage regulators are used in power supplies that hold their output voltage constant over a wide range of load variations.
Instrumentation Amplifier Chips (52 suppliers)
Instrumentation amplifier chips are precision amplifier circuits with both high-impedance differential inputs and high common-mode rejection.
Isolation Amplifiers (52 suppliers)
Isolation amplifiers electrically isolate input and output signals, often by inductive couplings. Isolation amplifiers, or iso-amps as they are sometimes called, may be used to protect components from potentially dangerous voltages or to amplify low-level analog signals in applications with multiple channels.
Logarithmic Amplifier Chips (24 suppliers)
Logarithmic amplifier chips produce an output voltage that is directly proportional to the logarithm of the input voltage.
Operational Amplifiers (149 suppliers)
Operational amplifiers (op amps, op-amps) are general-purpose, closed-loop devices that are used to implement linear functions.
Operational Transconductance Amplifiers (OTA) (11 suppliers)
Operational transconductance amplifiers (OTA) are devices that convert an input voltage to an output current. They are primarily voltage-to-current amplifiers.
Passive Filters (19 suppliers)
Passive filters are implemented using only passive components such as resistors, capacitors and inductors. These filters do not produce any amplification of the input signal.
Power Operational Amplifiers (74 suppliers)
Power operational amplifiers (POA) are used to increase the power of low-level signals in applications that drive low impedances or reactive loads. They dissipate excess energy as heat, deliver extensive current, and can sustain relatively high supply voltages.
PWM Amplifier Chips (47 suppliers)
Pulse width modulated (PWM) amplifier chips generate a current that switches between high and low output levels. PWM amplifiers have a much higher power capability for a given volume than linear amplifiers. They are also less expensive.
Sample-and-Hold Amplifiers (44 suppliers)
Sample-and-hold amplifiers freeze analog voltage instantly. During this process the HOLD command is issued and analog voltage is available for an extended period.
SAW Filters (88 suppliers)
SAW filters are electronic filters that are designed and manufactured using surface acoustic wave (SAW) technology. SAW uses piezoelectric transducers that, when excited, produce waves that are used to filter frequencies.
Transimpedance Amplifiers (29 suppliers)
Transimpedance amplifiers are operational amplifiers used to convert an input current into an output voltage. These current-to-voltage converters are useful in many important applications.
Video Amplifier Chips (44 suppliers)
Video amplifier chips are used in circuits to process video signals.
