5.4 Operational Amplifier (OPA)

The Microchip AVR family of devices do not offer an integrated Operational Amplifier (OPA) peripheral, but when migrating from AVR family to the MSPM0 family, you can make use of the MSPM0 internal OPAs to replace external discrete devices, or to buffer internal signals as necessary. The MSPM0 OPA modules are completely flexible, and can individually, or in combination, replace many discrete amplifiers in sensing or control applications. The primary features of the MSPM0 OPA modules are included in Table 5-5, and examples of common OPA configurations you can recreate are included in OPA code examples

Table 5-5 MSPM0 OPA Feature Set

Gain bandwidth 1 MHz (low-power mode)
6 MHz (standard mode)
Amplifier configurations General-purpose mode
Buffer mode
PGA mode (inverting or noninverting)
Differential amplifier mode
Cascade amplifier mode
Input/output routing External pin routing
Internal connections to ADC and COMP modules
Fault detection Burnout current source (BCS)
