The AD7324 is a 12-bit plus sign ADC with four analog input channels, supporting single-ended, true differential, and pseudo differential analog input, selectable input ranges of ±10V, ±5V, ±2.5V and 0V to +10V, 1MSPS throughput rate, power consumption of only 21mW, support for internal 2.5V reference voltage, support for high bandwidth signals, and multiple power supply modes. The package is a 16-lead TSSOP.
The AD7324 is a 4‑channel, 12‑bit plus sign successive‑approximation ADC designed on an iCMOS process. It supports true bipolar input signals and offers four software‑selectable input ranges (+10 V, +5 V, +2.5 V, and 0 V to +10 V). The device features a high‑speed serial interface compatible with SPI, QSPI, DSP and Microwire protocols, and provides a channel sequencer for flexible sampling.
Key specifications include a 13‑bit resolution, 1 MSPS maximum throughput, 22 MHz full‑power bandwidth, and a normal‑mode power dissipation of 30 mW. The ADC is supplied in a 16‑lead TSSOP package and operates over a temperature range of –40 °C to +85 °C. Detailed timing, absolute‑maximum ratings, and power‑down modes are provided for system designers.
| Resolution | 13 bits |
|---|---|
| Maximum Throughput Rate | 1 MSPS |
| Full Power Bandwidth | 22 MHz (3 dB) |
