10.1 Introduction
The MSP432E4 microcontroller provides two ADC modules with each having the following features:
- 24 shared analog input channels
- 12-bit precision ADC
- Single-ended and differential-input configurations
- On-chip internal temperature sensor
- Maximum sample rate of two million samples/second
- Optional, programmable phase delay
- Sample and hold window programmability
- Four programmable sample conversion sequencers from one to eight entries long, with corresponding conversion result FIFOs
- Flexible trigger control
- Controller (software)
- Timers
- Analog Comparators
- PWM
- GPIO
- Hardware averaging of up to 64 samples
- Eight digital comparators
- Converter uses two external reference signals (VREFA+ and VREFA-) or VDDA and GNDA as the voltage reference
- Power and ground for the analog circuitry is separate from the digital power and ground
- Efficient transfers using Micro Direct Memory Access Controller (µDMA)
- Dedicated channel for each sample sequencer
- ADC module uses burst requests for DMA
- Global Alternate Clock (ALTCLK) resource or System Clock (SYSCLK) can be used to generate ADC clock
