The Operational Amplifier (OPA) module features a standard general purpose three-terminal device with programmable gain options, adjustable input offset voltage and hardware override control capabilities. The OPA module has the following features:
- 2.3 MHz Gain Bandwidth
- Dedicated external output (OPAxOUT) (14-pin devices and above)
- Multiple noninverting input pins available (OPAxIN+)
- Multiple inverting input pins available (OPAxIN-)
- Programmable Gain Options Using Built-in Internal Resistor Ladder
- Configurable Positive and Negative Source Selections
- Hardware Controlled Drive with
Override Controls
- Forced Unity Gain mode
- Forced Rail Drive mode
- Programmable Input Offset Voltage Calibration
- Internal Connection to the ADC
Module
- Allows OPA to be used as programmable gain amplifier for the ADC Input
