Fast Throughput analog-to-digital converter that operates from a single 5 V power The AD7650 is a 570 kSPS, charge redistribution, 16-bit supply. The part contains a high-speed 16-bit sampling ADC, SAR ADC. an internal conversion clock, error correction circuits, and both 2. Single-Supply Operation serial and parallel system interface ports. The AD7650 operates from a single 5 V supply. In impulse It features a very high sampling rate mode (Warp) and, for mode, its power dissipation decreases with the throughput from asynchronous conversion rate applications, a fast mode (Normal) 77 mW at 444 kSPS throughput to, for instance, only 21 W and, for low power applications, a reduced power mode (Impulse) at a 100 SPS throughput. It consumes 7 W maximum when where the power is scaled with the throughput. in power-down. It is fabricated using Analog Devices high-performance, 3. Serial or Parallel Interface 0.6 micron CMOS process and is available in a 48-lead LQFP Versatile parallel or 2-wire serial interface arrangement com- or in a tiny 48-lead Chip Scale package with operation specified patible with both 3 V or 5 V logic. from 40C to +85C.
