Programmable-Gain Amplifier, Using the MAX532 DAC
Abstract: This application note discusses how to use the MAX532 to build a programmable gain amplifier (PGA)
that's suitable for AC gain control. No external components are necessary. Equations are provided to easily
calculate the output values.
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
