Data acquisition and signal conditioning IC collect, amplify, digitize and process multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes.
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.
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.
Analog-to-digital converter (ADC) chips transform information from analog to digital form.
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.
Digital-to-analog converter (DAC) chips convert digital signals that represent binary numbers into proportional analog voltages.
Frequency-to-voltage converter chips provide an analog voltage output as a function of the input signal frequency.
Instrumentation amplifier chips are precision amplifier circuits with both high-impedance differential inputs and high common-mode rejection.
Operational amplifiers (op amps, op-amps) are general-purpose, closed-loop devices that are used to implement linear functions.
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.
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 freeze analog voltage instantly. During this process the HOLD command is issued and analog voltage is available for an extended period.
Signal conditioner chips are data acquisition devices that refine sensor outputs so that they can be read by computer boards or other IC devices.
Voltage references are electronic circuits that produce a constant output voltage (reference) that is used to compare other voltages in a system.
