ANALOG DEVICES  AD7811YRZ  模数转换器, 10 bit, 350 kSPS, 单, 2.7 V, 5.5 V, SOIC

The is a 10-bit 4/8-channel sampling Analog-to-digital Converter ADC that operate from a single 2.7 to 5.5V supply. The device contains a 2.3µs successive approximation A/D converter, an on-chip track/hold amplifier, a 2.5V on-chip reference and a high speed serial interface that is compatible with the serial interfaces of most DSPs and microcontrollers. The user also has the option of using an external reference by connecting it to the VREF pin and setting the EXTREF bit in the control register. The VREF pin may be tied to VDD. At slower throughput rates the power-down mode may be used to automatically power down between conversions. The control registers of the converter allows the input channels to be configured as single-ended or pseudo differential. The control register also features a software convert start and a software power-down.
