Control Peripherals
Fast & Flexible
12-bit 16-Channel ADC
6.25 MSPS throughput
Dual sample/hold enable
simultaneous sampling or
sequencing sampling modes
Analog input: 0V to 3V
16 channel, multiplexed inputs
Auto Sequencer supports up to 16
conversions without CPU
intervention
Sequencer can be operated as two
independent 8-state sequencers or
as one large 16-state sequencer
Sixteen result registers (individually
addressable) to store conversion
values
