Description
General part information
ADC121S705 Series
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 VAdivided 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.
