Available units selected from 10 to 10dB 90dB programmable gain amplifier


Posted on Mar 28, 2007

Although the basic amplifier circuit phase AC amplifier are the same, no special change, but in order to select the correct magnification, the circuit uses ugly series resistan

ce does not have 9k0. Resistance. The input amplifier Ai selected OP37 (even if magnification is large, deterioration of properties is small, does not fill phase compensation) in order to remove the power supply line broadband noise, the circuit increased by the clamor, g5 and chu 5, c4 filter constituted. Although Ai ~ As can adopt a common OP amplifier, but the conversion rate should be 10 V/s or more. In order not to increase the DC offset voltage amplifier stage equipment are used 1011F electric vessel so that the flow at a magnification of 10 wins
