Description
The AD7175-2BRUZ-RL7 is a high-precision, low-power, 24-bit Sigma-Delta (Σ-Δ) ADC from Analog Devices. It features 31.25 kSPS max output data rate, ultra-low noise (1.5 µV RMS), and true 24-bit resolution with no missing codes.
Key features:
- Inputs: 4/8 differential/single-ended channels (flexible via multiplexer).
- Interface: SPI-compatible serial interface.
- Power: Low power consumption (1 mA at 31.25 kSPS, 2.5 µA in standby).
- Applications: Industrial process control, PLCs, medical instrumentation, and precision sensor measurement.
The -RL7 suffix indicates a tape-and-reel packaging option. The ADC includes on-chip calibration, a low-drift internal reference, and supports ±VREF bipolar input ranges.
Ideal for high-accuracy, low-speed signal acquisition in harsh environments.
