The ADC121S625 is a 12-bit, 50 ksps to 200 ksps sampling Analog-to-Digital (A/D) converter that features a fully differential, high impedance analog input and an external reference. While best performance is achieved with reference voltage between 500mV and 2.5V, the reference voltage can be varied from 100mV to 2.5V, with a corresponding resolution between 49µV and 1.22mV.
The output serial data is binary 2's complement, and is compatible with several standards, such as SPI™, QSPI™, MICROWIRE™, and with many common DSP serial interfaces. The differential input, low power, automatic power down, and small size make the ADC121S625 ideal for direct connection to transducers in battery operated systems or remote data acquisition applications.
Operating from a single +5V supply, the normal power consumption is reduced to a few nanowatts in the power-down mode. The ADC121S625 is a pin-compatible superior replacement for the ADS7817 and is available in the MSOP-8 package. Operation is guaranteed over the industrial temperature range of -40°C to +85°C and clock rates of 800 kHz to 3.2 MHz.
