The AD7328 is an 8-channel, 12-bit plus sign successive approximation ADC designed on the iCMOS™ (industrial CMOS) process. iCMOS is a process combining high voltage silicon with submicron CMOS and complementary bipolar technologies. It enables the AD7328 to provide high performance and high accuracy at low power and cost.
The AD7328 from Analog Devices is an 8‑channel, 12‑bit plus‑sign successive‑approximation ADC designed on iCMOS technology. It offers true bipolar input ranges (+10 V, +5 V, +2.5 V, 0 V‑to‑+10 V) and can be programmed per channel for single‑ended, true differential, or pseudo‑differential operation.
The device includes an internal 2.5 V reference (or external reference option), a high‑speed serial interface compatible with SPI/QSPI/DSP/MICROWIRE, and low power consumption (31 mW in normal mode). Detailed specifications, pin configurations, timing diagrams, and absolute maximum ratings are provided.
