Description

The AD7734BRUZ-REEL7 is a high-precision, 24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC) from Analog Devices. Designed for low-frequency measurement applications, it features four differential or seven pseudo-differential input channels with programmable gain (1–128).
Key highlights:
- Resolution: 24-bit, ensuring high accuracy.
- Inputs: 4 fully differential or 7 pseudo-differential channels.
- Gain: Programmable PGA (1x to 128x) for signal conditioning.
- Interface: SPI-compatible serial interface for easy microcontroller integration.
- Power: Low-power operation (3V or 5V supply), suitable for portable devices.
- Applications: Weigh scales, industrial process control, and medical instrumentation.
The -REEL7 suffix indicates it comes in tape-and-reel packaging for automated assembly. Its robust design and high performance make it ideal for demanding measurement systems.
