12位4通道串行输出采样模拟数字转换器 12-Bit, 4-Channel Serial Output Sampling ANALOG-TO-DIGITAL CONVERTER
DESCRIPON
The ADS7841 is a 4-channel, 12-bit sampling Analog-to Digital Converter ADC with a synchronous serial interface. The resolution is programmable to either 8 bits or 12 bits. Typical power dissipation is 2mW at a 200kHz through put rate and a +5V supply. The reference voltage VREF can be varied between 100mV and VCC, providing a correspond ing input voltage range of 0V to VREF. The device includes a shutdown mode which reduces power dissipation to under 15µW. The ADS7841 is tested down to 2.7V operation.
