Texas Instruments ADC121S705CIMM

Description
The ADC121S705 is a 12-bit, 500 KSPS to 1 MSPS sampling Analog-to-Digital (A/D) converter that features a fully differential, high impedance analog input and an external reference. The reference voltage can be varied from 1.0V to VA with a corresponding resolution between 244µV and VA divided by 4096.
The output serial data is binary 2's complement and is compatible with several standards, such as SPI/QSPI/MICROWIRE, and many common DSP serial interfaces. The differential input, low power consumption, and small size make the ADC121S705 ideal for direct connection to transducers in battery-operated systems or remote data acquisition applications.
Operating from a single 5V supply, the supply current when operating at 1 MSPS is typically 2.3 mA. The supply current drops down to 0.3 μA typically when the ADC121S705 enters power-down mode. The ADC121S705 is available in the VSSOP-8 package. Operation is ensured over the industrial temperature range of -40°C to 105°C and clock rates of 8 MHz to 16 MHz.
