Introduction
AD7928BRUZ - 12-bit, 8-channel, 1 MSPS SAR ADC with Integrated MUX/S/H
Core Functionality
The AD7928BRUZ is a high-precision, low-power 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) featuring:
- 8-channel operation with integrated multiplexer (MUX) and sample-and-hold (S/H) circuit
- 1 MSPS maximum sampling rate with 12-bit resolution
- Excellent accuracy: ±1 LSB INL and ±0.5 LSB DNL
- Single power supply operation from 2.7V to 5.25V
- Flexible input configurations: supports both single-ended and differential inputs
- Configurable input voltage range (0V to VREF or VREF/2)
- SPI interface with daisy-chain capability for system integration
- Power-saving modes (auto-shutdown and standby) for battery-powered applications
Key Applications
- Industrial Automation: PLCs, DCS systems, and process monitoring equipment for temperature, pressure, flow, and position sensing
- Test & Measurement: Portable oscilloscopes, data loggers, multimeters, and signal analyzers requiring high resolution and fast sampling
- Automotive Electronics: Engine control units, battery management systems, and infotainment devices
- Medical Devices: Patient monitoring systems, diagnostic tools, and imaging equipment
- Consumer Electronics: Smartphones, tablets, cameras, and wearables for audio, touch, and environmental sensing
- Communications: Base stations, modems, and wireless transceivers for signal processing
