概述

Description

AD7177-2BRUZ-RL7 is Analog Devices’ two-channel, 24-bit sigma-delta ADC designed for precision sensing and instrumentation. Key points:
- Dual differential inputs with selectable ranges and an integrated programmable-gain front end.
- Two-channel, high-resolution ADC suitable for bridges, weigh scales, pressure/force sensing, and other precision sensors.
- Programmable data rates and digital filters, with a SPI-compatible serial interface for control and data readback.
- External reference input option, low drift and low noise for accurate, long-term measurements; supports low power modes.
- Packaging suffixes indicate RoHS-compliant, lead-free device with a specific reel/packaging version (RL7).
Used where high resolution and stable performance are required at low frequencies, such as industrial instrumentation, medical devices, and precision measurement systems.

Features

AD7177-2BRUZ-RL7 features (concise):
- 24-bit sigma-delta ADC with high dynamic range and low noise
- Multi-channel differential/bridge sensor interface (suitable for weigh scales and instrumentation)
- Programmable data rate with selectable digital filters
- Programmable gain and bridge excitation options
- Auto-calibration (offset/gain) and self-test
- SPI-compatible serial interface for control and data
- Internal reference option with external reference compatibility
- Low power consumption with various power-down modes
- Industrial temperature range available (robust for harsh environments)
- Small, advanced packaging (BRUZ-RL7 LFCSP)
Note: For exact channel count, data-rate options, and electrical characteristics, please refer to the latest ADI datasheet.

Package

It uses a 28‑lead LFCSP (lead-frame chip-scale package) with an exposed pad, RoHS compliant.

Pinout

Pin count: 28 pins (BRUZ package).
Function: Dual-channel, 24-bit sigma-delta ADC with SPI-compatible serial interface.
