AD7327 is an 8-channel, 500 kSPS, 12-bit plus sign SAR ADC from Analog Devices with software selectable input ranges including ±10 V, ±5 V, ±2.5 V, and 0 V to +10 V. AD7327 supports single-ended, true differential, and pseudo differential analog inputs with high analog input impedance and low power.
The AD7327 is an 8‑channel, 12‑bit plus sign successive‑approximation ADC designed on iCMOS technology. It accepts true bipolar analog inputs and offers four software‑selectable input ranges (+10 V, +5 V, +2.5 V, and 0 V to +10 V). Each channel can be programmed for single‑ended, true differential, or pseudo‑differential operation.
Key features include a 500 kSPS serial interface, low 18 mW power consumption in normal mode, a full‑power bandwidth of 22 MHz, and a 20‑lead TSSOP package. The device provides extensive timing specifications, multiple power‑down modes, and an internal 2.5 V reference.
