The AD7665 is a 16-bit, 570 kSPS, charge redistribuTIon SAR, analog-to-digital converter that operates from a single 5 V power supply. It contains a high speed 16-bit sampling ADC, a resistor input scaler that allows various input ranges, an internal conversion clock, error correcTIon circuits, and both serial and parallel system interface ports. The AD7665 is hardware factory-calibrated and is comprehensively tested to ensure such ac parameters as signal-to-noise raTIo (SNR) and total harmonic distorTIon (THD), in addition to the more traditional dc parameters of gain, offset, and linearity. It features a very high sampling rate mode (Warp), a fast mode (Normal) for asynchronous conversion rate applications, and for low power applications, a reduced power mode (Impulse) where the power is scaled with the throughput.It is fabricated using Analog Devices’ high performance, 0.6 micron CMOS process and is available in a 48-lead LQFP and a tiny 48-lead LFCSP with operation specified from –40°C to +85°C
