Part # Distributor Manufacturer Product Category Description
TC1035 Microchip Technology, Inc. Microchip Technology, Inc. Not Provided with large input and output signal swings. An active low shutdown input, SHDN, disables the op amp, placing its output in a high-impedance state. The TC1035 draws less than 0.1 µA when the shutdown mode is active. Packaged in a 6-pin SOT-23A, this single operational amplifier is ideal...
TC850 Microchip Technology, Inc. Microchip Technology, Inc. Not Provided noncritical passive components are required to form a complete 15-bit plus sign ADC. CMOS processing provides the TC850 with high-impedance differential inputs.Input bias current is typically only 30pA, permitting direct interface to sensors. Input sensitivity of 100 µV per least significant bit...

  • AN721: Impedance Matching Networks Applied to RF Power Transistors, Courtesy of Motorola
    Some graphic and numerical methods of impedance matching will be reviewed here. The examples given will refer to high frequency power amplifiers. Although matching networks normally take the form of filters and therefore are also useful to provide frequency discrimination, this aspect will only

  • AN3012: Electrical Characterization of MAAMSS0031 CATV Amplifier at +5 Volts and Reduced Gain
    The MAAMSS0031 CATV amplifier is a GaAs MMIC which exhibits low noise and high linearity. It is ideally suited for set top boxes, home gateways, and other broadband internet based appliances. This amplifier is a monolithic single stage design in a 75 ohm input/output impedance environment
  • The sound which microphone received is too low
    Normally, the higher the impedance is, the better the sensitivity will be. However if the impedance is too high to get enough voltage/current, the high frequency response may get worse. Input higher voltage will increase the sensitivity. Depend on the design of the amplifier and the frequency
