The dual 12-bit ADC operates from a single 3 V supply over 2.7 V to 3.6 V and supports 20, 40, and 65 MSPS speed grades. It integrates dual sample-and-hold amplifiers, an on-chip voltage reference, differential analog inputs with 500 MHz bandwidth, and a multistage pipelined architecture with output error correction. The converter supports 1 V p-p to 2 V p-p input ranges, offset-binary or twos-complement output format, a clock duty-cycle stabilizer, and an output data multiplex option. Industrial-temperature operation is specified from -40 °C to +85 °C in 64-pin LQFP or 64-pin LF-CSP packages.
