The AD7915/AD7916 are 16-bit, successive approximation, analog-to-digital converters (ADCs) that operate from a single power supply, VDD. They contain a low power, high speed, 16-bit sampling ADC and a versatile serial interface port. On the CNV rising edge, the AD7915/AD7916 sample the voltage difference between the IN+ and IN− pins. The voltages on these pins typically swing in opposite phases between 0 V and VREF. The reference voltage, REF, is applied externally and can be set independent of the supply voltage, VDD. Its power scales linearly with throughput.
The AD7915/AD7916 are serial peripheral interface (SPI) compatible, which features the ability, using the SDI input, to daisy-chain several ADCs on a single 3-wire bus. It is compatible with 1.8 V, 2.5 V, 3 V, and 5 V logic, using the separate VIO supply.
The AD7915/AD7916 are available in a 10-lead MSOP or a 10-lead LFCSP with operation specified from −40°C to +125°C.APPLICATIONS
