AD7655SCP-EP-RL

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.
