3.3.12 Programmable Gain Amplifier (PGA) Module

The Programmable Gain Amplifier (PGA) module is designed to buffer and amplify small input signals into an output range that is an excellent choice for the on-chip ADC and Comparator modules.

Refer to the device-specific technical reference manual for more information.

Table 3-46 lists the PGA types, including device-specific differences within each type.

Table 3-46 Programmable Gain Amplifier (PGA) Module Type Description
TypeDescriptionDevices CoveredDevice-Specific Options
0Original PGA Module Type2805xProgrammable gain modes: 3˟, 6˟, 11˟
1Added gain mode of 24˟. Supports Low-Pass Filtering. Features Hardware-based trims to reduce offset and gain errors.28004xProgrammable gain modes: 3˟, 6˟, 12˟, 24˟
2

Added supports for buffer (Unity Gain), standalone op-amp, and subtractor operation modes. Rail to rail on both input pins. Internal negative input sharing across PGAs. Hardware assisted chopping for offset and 1/f noise reduction.
