Description
This design is for a 16-bit 1MSPS single-ended, multiplexed data acquisition system (DAQ) for dc inputs. The system is composed of a 16-bit successive-approximation-register (SAR) analog-to-digital converter (ADC), SAR ADC driver, reference driver, and multiplexer. The design shows the process to optimize a single-ended DAQ to achieve fast settling at a sampling rate of 1MSPS.
Features
- 1/2 LSB settling in 390 ns
- Throughput of 1MSPS
- 4 V output step
- Measured Effective Resolution of 15.72 bits
- Measured ENOB of 13.57 bits
