The AD7264 is a dual, 14-bit, high speed, low power, successive approximation ADC that operates from a single 5 V power supply and features throughput rates of up to 1 MSPS per on-chip ADC (500 kSPS for the AD7264-5). Two complete ADC functions allow simultaneous sampling and conversion of two channels. Each ADC is preceded by a true differential analog input with a PGA. There are 14 gain settings available: x1, x2, x3, x4, x6, x8, x12, x16, x24, x32, x48, x64, x96, and x128. The AD7264 contains four comparators. Comparator A and Comparator B are optimized for low power, whereas Comparator C and Comparator D have fast propagation delays. The AD7264 features a calibration function to remove any device offset error and programmable gain adjust registers to allow for input path (for example, sensor) offset and gain compensation. The AD7264 has an on-chip 2.5 V reference that can be disabled if an external reference is preferred. The AD7264 is available in 48-lead LFCSP and LQFP packages.
