分享资料个
The AD7654 is a low cost， simultaneous sampling， dual-channel， 16-bit， charge redistribution SAR， analog-to-digital converter that operates from a single 5 V power supply. It contains two low noise， wide bandwidth， track-and-hold amplifiers that allow simultaneous sampling， a high speed 16-bit sampling ADC， an internal conversion clock， error correction circuits， and both serial and parallel system interface ports. Each track-and-hold has a multiplexer in front to provide a 4-channel input ADC. The A0 multiplexer control input allows the choice of simultaneously sampling input pairs INA1/INB1 （A0 = low） or INA2/INB2 （A0 = high）。 The part features a very high sampling rate mode （normal） and， for low power applications， a reduced power mode （impulse） where the power is scaled with the throughput. Operation is specified from −40°C to +85°C..
