AD7172-4BCPZ

AD7172-4BCPZ is Analog Devices’ high-precision, 24-bit delta-sigma ADC with four input channels. It’s designed for precision instrumentation and sensor interfaces (e.g., weigh scales, strain-gauge bridges, low-frequency measurement).
Key points:
- Four differential input channels with programmable gain/PGA per channel and a programmable digital filter for low-noise, high-dynamic-range conversion.
- SPI-compatible serial interface for fast, flexible data readout.
- Suitable for bridge sensors and low-frequency signals, offering high resolution and low drift.
- Includes features common to precision ADCs such as calibration options and stable performance over temperature.
Package/availability:
- AD7172-4BCPZ uses a lead-frame chip-scale package (LFCSP) variant, RoHS-compliant. The “BCPZ” suffix denotes this package/configuration from Analog Devices.
Applications:
- Precision instrumentation, weighing systems, process control, battery-powered sensors requiring stable 24-bit resolution.
