The AD7655 is a low cost, simultaneous sampling, dual-channel,16-bit, charge redistribution SAR, analog-to-digital converterthat operates from a single 5 V power supply. It contains twolow noise, wide bandwidth, track-and-hold amplifiers that allowsimultaneous sampling, a high speed 16-bit sampling ADC, aninternal conversion clock, error correction circuits, and bothserial and parallel system interface ports. Each track-and-holdhas a multiplexer in front to provide a 4-channel input ADC.The A0 multiplexer control input allows the choice ofsimultaneously sampling input pairs INA1/INB1 (A0 = low) orINA2/INB2 (A0 = high). The part features a very high samplingrate mode (normal) and, for low power applications, a reducedpower mode (impulse) where the power is scaled with thethroughput. Operation is specified from −40°C to +85°C.
Product Highlights
- Multichannel ADC.
The AD7655 features 4-channel inputs with two sample-and-hold circuits that allow simultaneous sampling. - Fast Throughput.
The AD7655 is a 500 kSPS, charge redistribution, 16-bit SAR ADC with internal error correction circuitry. - Single-Supply Operation.
The AD7655 operates from a single 5 V supply. In impulse mode, its power dissipation decreases with throughput. - Serial or Parallel Interface.
Versatile parallel or 2-wire serial interface arrangements are compatible with both 3 V and 5 V logic.
Applications
- AC motor control
- 3-phase power control
- 4-channel data acquisition
- Uninterrupted power supplies
- Communications
