Analog Devices AD7654ACPZRL

Single ADC SAR 500ksps 16-bit Parallel/Serial 48-Pin LFCSP EP T/R

16-BIT SAR ADC, 4 CHANNEL

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. APPLICATIONS AC motor control 3-phase power control 4-channel data acquisition Uninterrupted power supplies Communications
