AD7730BRZ

The AD7730BRZ is a high-precision, 24-bit sigma-delta ADC from Analog Devices, designed for low-frequency measurement applications. It features on-chip digital filtering, a programmable gain amplifier (PGA), and low noise, making it ideal for weigh scales, strain gauges, and industrial sensors.
Key specifications:
- Resolution: 24 bits (no missing codes).
- Inputs: Differential or pseudo-differential.
- Data Rate: Up to 1.2 kHz (adjustable).
- PGA Gains: 1 to 128.
- Interface: SPI-compatible serial.
- Supply Voltage: +5V (single supply) or ±5V (dual supply).
The AD7730BRZ includes self-calibration and system calibration modes, ensuring accuracy over temperature and time. Its low power consumption (~5 mW) suits battery-powered devices.
Applications include process control, medical instruments, and precision data acquisition. The BRZ suffix denotes a 28-lead SOIC package.
For detailed use, refer to the datasheet for register configurations and timing diagrams.
