AD7940规格书详情
GENERAL DESCRIPTION
The AD7903 is a dual 16-bit, successive approximation, analog to-digital converter (ADC) that operates from a single power supply, VDDx, per ADC. It contains two low power, high speed, 16-bit sampling ADCs and a versatile serial port interface (SPI). On the CNVx rising edge, the AD7903 samples the voltage difference between the INx+ and INx− pins. The voltages on these pins usually swing in opposite phases between 0 V and VREF. The externally applied reference voltage of the REFx pins (VREF) can be set independently from the supply voltage pins, VDDx. The power of the device scales linearly with throughput.
Using the SDIx inputs, the SPI-compatible serial interface can also daisy-chain multiple ADCs on a single 3-wire bus and provide an optional busy indicator. It is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic, using the separate VIOx supplies.
The AD7903 is available in a 20-lead QSOP package with operation specified from −40°C to +125°C.

AD7940属于集成电路(IC) > 模数转换器(ADC)。亚德诺半导体技术有限公司制造生产的AD7940模数转换器(ADC)模数转换器(ADC、A/D 或 A 转 D)对模拟信号进行采样,例如由麦克风采集的声音或传感器的输出,然后将其转换为数字信号。一般来说,数字输出是二进制补码二进制数,与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构(例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式)进行选择。
