The AD15452 is a Quad, 12-bit, 65MSPS, analog-to-digital converter(ADC). It features a differential front-end amplification circuit followed by a sample-and-hold amplifier and multistage pipeline analog-to-digital converter. It is designed to operate with a +3.3 V analog supply and +3.3 V digital supply. Each input is fully differential. The input signals are AC coupled and terminated in 100 Ω input impedances. The full scale differential signal input range is 296 mV pp.

Four separate 12-bit digital output signals provide data flow from the ADCs. The digital output data is presented in offset binary format. A single single-ended clock input is used to control all internal conversion cycles. The AD15452 is optimized for applications in anti-jam global positioning receivers and is suited for communications applications.
