IC ADC 16BIT SAR 250KSPS 10LFCSP
The AD76871 is a 16-bit, charge redistribution, successive approximation, analog-to-digital converter (ADC) that operates from a single power supply, VDD, between 2.3 V to 5.5 V. It contains a low power, high speed, 16-bit sampling ADC with no missing codes, an internal conversion clock, and a versatile serial interface port. The device also contains a low noise, wide bandwidth, short aperture delay track-and-hold circuit. On the CNV rising edge, the AD7687 the samples the voltage difference between IN and IN− pins, which can range from −VREF to VREF. The reference voltage, VREF, is applied externally and can be set up to the supply voltage. The power consumption of the device scales linearly with throughput. The SPI-compatible serial interface also features the ability to daisy-chain several ADCs on a single 3-wire bus and provides an optional BUSY indicator by means of the SDI pin. It is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic using the separate supply VIO. The AD7687 comes in a 10-lead MSOP or a 10-lead LFCSP with operation specified from −40°C to 85°C.
