2.3.7.2 Light Sensor

A light sensor circuit is provided on the EVM by using the photodiode in configuration shown in Figure 2-8. The jumper connections between this circuit and the MSPM0 are populated by default so the photodiode is in circuit. The jumpers can be removed to place the photodiode out of circuit so the MSPM0 connections can be used for other evaluation purposes.

GUID-20221006-SS0I-WBZV-DWRN-HZKZ7GVPR4BQ-low.png Figure 2-8 Light Sensor Circuit

This circuit is intended to be used with the internal OPA of the MSPM0 in an transimpedance configuration to drive the circuit. The OPA output is internally set to an ADC channel for sampling. See Table 2-1 for device-specific module connections and Section 3 for example code.
