Analog Devices Inc. AD7610/AD7612 PulSAR® ADCs

Analog Devices Inc. AD7610/AD7612 PulSAR^® ADCs are 16-bit unipolar/bipolar programmable input ADCs constructed using iCMOS^® high-voltage process. These ADCs include a high-speed 16-bit sampling ADC, an internal conversion clock, an internal reference and buffer, serial and parallel system interface ports, and error correction circuits. The AD7610/AD7612 ADCs feature four different analog input ranges including 0V to 5V, 0V to 10V, ±5V, and ±10V. These ADCs provide designers with three different sampling modes. These modes include warp-mode for the fastest throughput, normal mode for the fastest asynchronous throughput, and impulse mode where power consumption is scaled linearly with throughput. Typical applications include process control, medical instruments, high-speed data acquisition, instruments, and spectrum analysis.
