Description
The AD7984BRMZ is a 16-bit, successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It features a high-speed 1 MSPS sampling rate, low power consumption (2.5 mW at 1 MSPS), and operates from a single 2.5 V to 5.5 V supply.
Key features include:
- 16-bit resolution with no missing codes.
- SPI-compatible serial interface for easy microcontroller interfacing.
- Integrated reference buffer (2.5 V internal reference).
- Wide input range (0 V to VREF) with true differential or single-ended operation.
- Small 10-lead MSOP package, suitable for space-constrained applications.
Ideal for portable instrumentation, industrial control, and data acquisition systems, the AD7984BRMZ balances speed, accuracy, and power efficiency. Its low noise and high linearity make it suitable for precision applications.
For detailed specs, refer to the datasheet.
