ADS122U04IPWR 24-Bit ADC Analog-to-Digital Converter for Industrial Sensors & IoT

ADS122U04IPWR 24-Bit ADC – 2kSPS, 4-Channel Δ-Σ Converter | PGA, IDAC & UART Interface

The ADS122U04IPWR from Texas Instruments is a 24-bit Δ-Σ ADC engineered for high-accuracy industrial sensing, IoT, and portable instrumentation. Featuring 2kSPS sampling, 4-channel input flexibility (2 diff/4 SE), and an integrated programmable gain amplifier (PGA: 1–128x), this ADC excels in precision signal acquisition from RTDs, thermocouples, and strain gauges.

With ultra-low power (1.4mW), a built-in 2.048V reference (5ppm/°C drift), and dual IDAC current sources (10µA–1.5mA), it eliminates external components while ensuring 50/60Hz noise rejection.

Ultra-Low Power 24-Bit ADC with Built-In PGA & Anti-Noise Filtering

Why Engineers Choose This ADC:
✅ 24-bit resolution (20-bit ENOB) for microvolt-level accuracy
✅ UART interface (120kBaud) + auto-baud detection for seamless MCU integration
✅ Wide 2.3V–5.5V supply for battery-powered & industrial systems
✅ Tiny 3mm² TSSOP package (RoHS/MSL3) for space-constrained designs
