The AD7452 is a 12-bit, high speed, low power, successive approximation (SAR) analog-to-digital converter (ADC) that features a fully differential analog input. This part operates from a single 3 V or 5 V power supply and has a maximum 555 kSPS input rate with 70 dB SINAD.
The AD7452 is a 12‑bit successive‑approximation ADC offering fully differential inputs, up to 555 kSPS throughput and low power operation from a single 3 V or 5 V supply. It includes a high‑speed serial interface compatible with SPI, QSPI, Microwire and DSP protocols, and a power‑down mode drawing as little as 1 pA.
Typical applications include transducer interfaces, battery‑powered systems, data‑acquisition, portable instrumentation and motor control. The device provides a wide input bandwidth, low noise performance and flexible clock‑speed management for optimized power usage.
