概述
Description
The AD7788ARMZ is a low-power, 24-bit sigma-delta (Σ-Δ) ADC from Analog Devices, designed for precision measurement applications. It features an integrated PGA (programmable gain amplifier) with gains from 1 to 128, enabling direct sensor interfacing (e.g., strain gauges, thermocouples).
Key specifications:
- Resolution: 24 bits (no missing codes).
- Output Rate: 4.17 Hz to 470 Hz (adjustable).
- Supply Voltage: 2.7V–5.25V, consuming just 65 µA (typ).
- Interface: SPI-compatible serial interface.
- On-Chip Features: Internal oscillator, reference, and PGA.
Applications include weigh scales, industrial process control, and portable instrumentation. Its low noise (40 nV RMS at 4.17 Hz) and high accuracy make it ideal for low-frequency signal acquisition. The AD7788ARMZ comes in a compact 10-lead MSOP package.
For detailed use, refer to its datasheet for calibration, filter settings, and layout guidelines.
