ADI Precision ADC

Key Features

• 16- to 32-bit resolution with no-missing-codes options
• Delta-sigma and SAR architectures
• On-chip PGA, reference and instrumentation front ends
• Multi-channel simultaneous-sampling variants
• SPI and parallel interfaces
• MSOP, TSSOP, LFCSP and LQFP packages

Packages, Temperature & Applications

ADI precision ADCs are supplied in MSOP, TSSOP, LFCSP and LQFP packages, across industrial temperature ranges. Applications include weigh scales, temperature and pressure measurement, power monitoring, medical instrumentation and industrial process control.

Selection Notes

Match resolution and sample rate to your signal: delta-sigma for slow, high-precision measurement, SAR for faster acquisition. Check the channel count, input range and whether an internal reference and PGA simplify your front end. Confirm restricted-availability parts by RFQ before ordering.

Popular Part Numbers

• AD7793BRUZ — 24-bit, 3-channel sigma-delta with PGA.
• AD7193BCPZ — 24-bit, 4-channel low-noise ADC.
• AD7689BCPZ — 16-bit, 8-channel SAR ADC.
• AD7609BSTZ — 18-bit, 8-channel simultaneous sampling.
• ADS1210U — 24-bit delta-sigma for precision measurement.

Design Considerations

Delta-sigma converters give the highest resolution for slow, low-noise signals such as weigh scales and temperature, while SAR converters provide lower-latency conversion for control loops. Check the channel count, input range and whether an internal reference and PGA reduce your external component count. Confirm restricted-availability parts by RFQ before ordering.

Why Choose This Series

ADI precision ADCs set the benchmark for measurement accuracy, with low noise, high linearity and on-chip front ends that simplify the signal chain. For weigh scales, temperature, power monitoring and industrial data acquisition where the measurement quality is the product, these converters provide the resolution and drift performance that competing parts struggle to match.
