Overview
The Analog-to-Digital Converter (ADC) is fully differential and based on a 12-bit pipelined topol-
ogy using switched capacitors circuitry. Two sample and hold (S/H) running simultaneously with
1, 2, 4, 8, 16, 32, 64 gain factors are feeding a single ADC analog block so that the system acts
as if there were two conversion running in parallel. It can be configured as a 8-bit 10-bit or 12-bit
ADC and is capable of converting 1.5 million samples per second thanks to its pipeline topology.
10-bit and 8-bit conversion resolution can be achieved at higher conversion rates. Note that
results are always signed in 2's complement.
Note: The pipelined topology implies a latency between the sampling event and the update of
the result register of: (Resolution(SRES)/2 + 3 - SHD)
The ADC has an internal defined conversion range of
mode allows conversion range of
nal references for different conversion ranges.
