PGA 100KHz is used as the analog input amplifier for the Analog to Digital Converter.
The purpose of the Control and Sensor PGA is to provide selectable voltage amplification of low level signals prior to conversion via an ADC. This amplifier provides different inputs to support a wide variety of applications.
Control and Sensor Programmable Gain Amplifiers are designed with TSMC 0.18 1P5M technology.
Total gain constants are 1x, 2x, 5x, 10x, 20x, 50x, 50x, 100x, 200x
Power supply 3.3V
Control PGA Area: 330×300µm2
Sensor PGA Area: 240×340µm2
Temperature range: -40C to +125C
