illustrate

The ADC121S655 is a 12-bit, 200 ksps, 500 ksps sampled analog-to-digital (A/D converter) converter with a fully differential high impedance analog input and an external reference. From 1.0V to V,_{corresponding}A is divided into 4096 resolutions of 244μV and V_betweenThe reference voltages can be varied.

THE OUTPUT SERIAL DATA IS BINARY 2 COMPLEMENT AND IS COMPATIBLE WITH SEVERAL STANDARD SPI, QSPI,™ MICROWIRE™,™ AND MANY COMMON DSP SERIAL INTERFACES. Differential input, low power consumption, and small size, ideal for connecting sensors directly to the ADC121S655 in battery-powered systems or remote data acquisition applications.

Operating from a single 5V supply with a supply current of 500 ksps, typically 1.8 mA. The supply current drops to 0.3μA, and a typical ADC121S655 enters power-down mode. ADC121S655 MSOP - 8 package. Operation is guaranteed over the industrial temperature range of -40 °C to +105 °C and clock rates of 3.2 MHz to 8 MHz.
