Description

16BIT ADC SAR 1MSPS LQFP48 5V

The AD7655 isalowcost, simultaneoussampling, dual-channel, 16-bit, charge redistribution SAR, analog-to-digital converter that operates from a single 5 V power supply. It containstwo 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, andboth serial and parallel system interface ports. Each track-and-hold has amultiplexer in front to provide a 4-channel input ADC. The A0 multiplexercontrol 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.
