AD7322BRUZ

AD7322BRUZ Description

The AD7322BRUZ from Analog Devices Inc. is a high-performance, 12-bit SAR (Successive Approximation Register) ADC designed for precision analog-to-digital conversion in demanding applications. Part of the iCMOS® series, it integrates a single ADC with a flexible SPI/DSP-compatible interface, supporting both unipolar and true bipolar input ranges (±10V, ±5V, ±2.5V, 0–10V, 0–5V). Its dual-supply operation (±12V to ±16.5V for analog, 2.7V–5.25V for digital) ensures compatibility with mixed-voltage systems. The device achieves a 1 MSPS sampling rate with a 1:1 S/H:ADC ratio, enabling accurate, high-speed signal acquisition. Housed in a 14-TSSOP package, it is ideal for space-constrained designs.
