AD7621 16-Bit, 2 LSB INL, 3 MSPS PulSAR® ADC
The AD7621 is a 16-bit, 3 MSPS, charge redistribution SAR, fully differential analog-to-digital converter that operates from a single 2.5 V power supply. The part contains a high-speed 16-bit sampling ADC, an internal conversion clock, an internal reference buffer, error correction circuits, and both serial and parallel system
interface ports.
It features a very high sampling rate mode (Wideband Warp) for undersampling applications and, for asynchronous conversion rate applications, a fast mode (Normal) and, for low power applications, a reduced power mode (Impulse) where the power is scaled with the throughput.
It is available in a 48-lead LQFP or a 48-lead LFCSP with operation specified from –40°C to +85°C.
