Product Summary

The adc122s625cimm is a dual 12-bit, 50 kSPS to 200 kSPS simultaneous sampling Analog-to-Digital (A/D) converter. The analog inputs on both channels are sampled simultaneously to preserve their relative phase information to each other. The converter is based on a successive-approximation register architecture where the differential nature of the analog inputs is maintained from the internal track-and-hold circuits throughout the A/D converter to provide excellent commonmode signal rejection. The adc122s625cimm features an external reference that can be varied from 1.0V to VA. Operating from a single 5V analog supply and a reference voltage of 2.5V, the total power consumption while operating at 200 kSPS is typically 8.6 mW. With the adc122s625cimm operating in power-down mode, the power consumption reduces to 2.6 μW. The differential input, low power consumption, and small size make the adc122s625cimm ideal for direct connection to sensors in motor control applications. Operation is guaranteed over the industrial temperature range of -40°C to +105°C and clock rates of 1.6 MHz to 6.4 MHz. The adc122s625cimm is available in a 10-lead MSOP package.
