Description
The AD7328BRUZ-REEL7 is a 12-bit, 8-channel successive approximation (SAR) analog-to-digital converter (ADC) from Analog Devices. It supports bipolar (±10V, ±5V) and unipolar (0–10V, 0–5V) input ranges, selected via software. Key features include:
- 8 single-ended or 4 pseudo-differential input channels.
- 1 MSPS sampling rate.
- SPI-compatible serial interface for communication.
- On-chip reference (2.5V) with external reference option.
- Low power (13.5 mW at 1 MSPS).
Packaged in a TSSOP-20, it’s suited for industrial control, data acquisition, and instrumentation. The "-REEL7" suffix indicates it comes on a 7-inch reel for automated assembly.
For detailed specs, refer to the datasheet.
