ADC10
18.1 ADC10 Introduction
The ADC10 module supports fast, 10-bit analog-to-digital conversions. The
module implements a 10-bit SAR core, sample select control, reference
generator, and data transfer controller (DTC).
The DTC allows ADC10 samples to be converted and stored anywhere in
memory without CPU intervention. The module can be configured with user
software to support a variety of applications.
ADC10 features include:
- Greater than 200 ksps maximum conversion rate
- Monotonic10-bit converter with no missing codes
- Sample-and-hold with programmable sample periods
- Conversion initiation by software or Timer_A
- Software selectable on-chip reference voltage generation (1.5 V or 2.5 V)
- Software selectable internal or external reference
- Eight external input channels
- Conversion channels for internal temperature sensor, V
CC
, and external
references
- Selectable conversion clock source
- Single-channel, repeated single-channel, sequence, and repeated
sequence conversion modes
- ADC core and reference voltage can be powered down separately
- Data transfer controller for automatic storage of conversion results
The block diagram of ADC10 is shown in Figure 18−1.
