22.1 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
• Monotonic 10-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
• Up to eight external input channels (twelve on MSP430F22xx devices)
• 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 22-1.
