The AD7262/AD7262-5 are dual, 12-bit, high speed, low power, successive approximation ADCs that operate from a single 5 V power sup, supports four comparators, with a on-chip reference voltage of 2.5 V.
The AD7262 is a dual‑channel, 12‑bit successive‑approximation ADC that provides simultaneous sampling at up to 1 MSPS per channel. It features a programmable gain amplifier with 14 gain settings, an on‑chip 2.5 V reference, and a high‑speed serial interface compatible with SPI, QSPI, Microwire, and DSP protocols.
The datasheet lists key specifications such as 73 dB SNR at gain = 2, 1 GΩ input impedance, four on‑chip comparators, and power consumption of 105 mW in static mode. Pin configurations, timing diagrams, absolute maximum ratings, and ordering information for LFCSP and LQFP packages are also provided.
