8.4 PGA (P89LPC9351/9361)
8.5 Temperature sensor
Additional PGA module is integrated in each ADC module to improve the effective
resolution of the ADC. A single channel can be selected for amplification. The gain of PGA
can be programmable to 2, 4, 8 and 16. Please refer to
detailed specifications.
Register PGACONx and PGACONxB are used to for PGA configuration. Register
PGAxTRIM2X4X and PGAxTRIM8X16X provide trim value of PGA gain level. As
power-on, default trim value for each gain setting is loaded into the PGA trim registers.
For accurate measurements, offset calibration is required.
Please see the P89LPC9331/9341/9351/9361 User manual for detail configuration,
calibration, and usage information.
An on-chip wide-temperature range temperature sensor is integrated with ADC0 module.
It provides temperature sensing capability of −40 °C ~ 85 °C. It is necessary to measure
the 1.2 V reference voltage via the ADC before measuring temperature. In
P89LPC9351/9361, the reference voltage, temperature sensor and AD03 input pin
multiplex one input to PGA0. Please see the P89LPC9331/9341/9351/9361 User manual
for detail usage of temperature sensor.
