Dual 12-bit, 200 Ksps To 500 Ksps, Simultaneous Sampling A/d Converter

The ADC122S655 is a dual 12-bit, 200 kSPS to 500 kSPS simultaneous sampling Analog-to-digital (A/D) converter. The Analog inputs on both channels are sampled simultane- ously 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 ana- log inputs is maintained from the internal track-and-hold cir- cuits throughout the A/D converter to provide excellent common-mode signal rejection. The ADC122S655 features an external reference that CAN be varied from 1.0V to VA. The ADC122S655 's serial data output is binary 2's comple- ment and is compatible with several standards, such as SPI, QSPI, MICROWIRE, and many common DSP se- rial Interfaces The serial Clock (SCLK) and chip select bar (CS) are shared by both channels. Operating from a single 5V Analog supply and a reference voltage of 2.5V, the total power consumption while operating at 500 kSPS is typically 11 mW. With the ADC122S655 op- erating in power-down mode, the power consumption re- duces to 3 W. The differential input, low power consumption, and small size make the ADC122S655 ideal for direct con- nection to Sensors in Motor Control applications. Operation is guaranteed over the industrial temperature range of 40C to +105C and Clock rates of 6.4 MHz to 16 MHz. The ADC122S655 is available in a 10-lead MSOP pack- age.
