The 32-bit resolution targets high-accuracy instrumentation, weigh scales, seismic monitoring, and industrial process control where noise floor and linearity dominate the signal chain budget. ## 32 bits at 4 kSPS — the resolution-speed trade-off The 32-bit resolution samples at 4 kSPS. The sigma-delta modulator oversamples and decimates to push quantization noise out of the passband.","metaTitle":"TI ADS1285IRHBT 32-Bit Sigma-Delta ADC, 4 kSPS, 32-VQFN","metaDescription":"TI ADS1285IRHBT 32-bit sigma-delta ADC, 4 kSPS, differential input, MUX-PGA-ADC, SPI, -40 to 85°C.
