Микросхема AD7685BRMZ, 16-бит АЦП [MSOP-10]

Характеристики

AD7685BRMZ, 16-бит АЦП [MSOP-10]The AD7685BRMZ is a 16-bit 250kSPS PulSAR® Analogue to Digital Converter (ADC) that operates from a single power supply between 2.3V and 5.5V. It contains a low power high speed 16-bit sampling ADC with no missing codes (B grade), an internal conversion clock and a serial SPI-compatible interface port. The part also contains a low noise wide bandwidth short aperture delay, track-and-hold circuit. On the CNV rising edge, it samples an analogue input IN+ between 0V to REF with respect to a ground sense IN-. The reference voltage, REF, is applied externally and can be set up to the supply voltage. Power dissipation scales linearly with throughput. The SPI-compatible serial interface also features the ability, using the SDI input, to daisy chain several ADCs on a single 3-wire bus or provides an optional BUSY indicator. It is compatible with 1.8, 2.5, 3 or 5V logic using the separate supply VIO.
