The AD7329 is a 12-bit successive approximation ADC with input ranges of ±10 V, ±5 V, ±2.5 V, and 0 V to +10 V. It supports eight analog input channels and features a channel sequencer. The AD7329 also supports single-ended, true differential, and pseudo differential analog input. The AD7329 has a low power consumption of 21 mW, a full power signal bandwidth of 20 MHz, and an internal 2.5 V reference. The AD7329 is fabricated using iCMOS™ process technology and is packaged in a 24-lead TSSOP.
The AD7329 is a 12‑bit plus‑sign successive‑approximation ADC with true bipolar input capability. It provides eight analog input channels that can be configured as single‑ended, true differential, or pseudo‑differential, and offers four software‑selectable input voltage ranges (+10 V, +5 V, +2.5 V, and 0 V to +10 V). The device features a high‑speed serial interface capable of up to 1 MSPS throughput and includes an internal 2.5 V reference or can operate with an external reference.
Key specifications include a 20 MHz full‑power bandwidth, low power consumption of 21 mW at 1 MSPS, and a 24‑lead TSSOP package. The datasheet provides detailed timing diagrams, absolute maximum ratings, and ESD protection guidelines for designers integrating the AD7329 into measurement and control systems.
