To provide a programmable-gain amplifier in which sufficiently fine and linear gain control according to the logic levels of control signals can be realized with a simple circuit configuration, a programmable-gain amplifier includes a cascade connection of differential amplifiers (E.sub. 1 to E.sub...
This function turns on the amplifier with the power and gain based on the settings provided during the configuration or the current values after PGA_Stop() has been called. Parameters: None Return Value: None Side Effects: None void PGA_Stop(void) Description: This fu...
The MAX532 is a dual, 12-bit, voltage-output DAC. Access to the output amplifier's input terminals allows it to be easily configured as a programmable-gain amplifier (PGA) suitable for AC gain control. The circuit configuration is that of an inverting amplifier, with R2 replaced by the ef...
The PGA implements an opamp-based, non-inverting amplifier with user-programmable gain. This amplifier has high input impedance, wide bandwidth and selectable input voltage reference. It is derived from the switched capacitor/continuous time (SC/CT) block. ...

It can be noted that, when using the configuration in Figure 8, the on-resistance of the switch is also in series with the high impedance input of the amplifier, and therefore it does not affect the gain. Looking back to the trade-off between on-resistance and switch inpu...
