The AD7265 is a dual, 12-bit, high speed, low power, successive approximation ADC that operates from a differential/single-ended input. It features dual 12-bit, 3-channel ADC, throughput rate of 1 MSPS, operating voltage range of 2.7 V to 5.25 V, power consumption of 7 mW, pin-configurable analog inputs, 70 dB SINAD accuracy, accurate on-chip reference, etc.
The AD7265 is a dual, 12‑bit, 3‑channel SAR ADC that operates from a 2.7 V to 5.25 V supply and provides up to 1 MSPS throughput. It features pin‑configurable analog inputs, on‑chip 2.5 V reference, and high‑speed serial interfaces (SPI, QSPI, Microwire, DSP‑compatible). The device is offered in 32‑lead LFCSP and thin‑quad TQFP packages.
The datasheet includes detailed specifications, timing diagrams, absolute maximum ratings, pin descriptions, package dimensions, and ordering information, as well as application hints for PCB layout and grounding.
