Single ADC SAR 1MSPS 16Bit Parallel/Serial 48Pin LFCSP EP T/R
Product Details
The AD7655 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.
Product Highlights
1. Multichannel ADC.
The AD7655 features 4-channel inputs with two sample-and-hold circuits that allow simultaneous sampling.
2. Fast Throughput.
The AD7655 is a 500 kSPS, charge redistribution, 16-bit SAR ADC with internal error correction circuitry.
3. Single-Supply Operation.
The AD7655 operates from a single 5 V supply. In impulse mode, its power dissipation decreases with throughput.
4. Serial or Parallel Interface.
Versatile parallel or 2-wire serial interface arrangements are compatible with both 3 V and 5 V logic.
