This document describes the AD7327 model from Analog Devices, which is a 500 kSPS, 8-channel, software-selectable, true bipolar input, 12-bit plus sign ADC. It features true bipolar input ranges, software-selectable input ranges, 500 kSPS throughput rate, eight analog input channels, high-speed serial interface, etc.
The AD7327 from Analog Devices is a 12‑bit plus‑sign successive‑approximation ADC offering true bipolar input ranges and software‑selectable voltage ranges (+10 V, +5 V, +2.5 V, 0‑10 V). It supports eight analog input channels that can be configured as single‑ended, true differential, or pseudo‑differential, and provides a high‑speed serial interface up to 500 kSPS.
The device is supplied in a 20‑lead TSSOP package, operates from a 12‑16.5 V supply, and features low power consumption (17 mW at maximum throughput). Detailed specifications include resolution, dynamic performance, timing parameters, absolute maximum ratings, and power‑down modes.
