ADS7841EBG4 Datasheet

Analog to Digital Converters - ADC


The ADS7841( ADS7841EBG4 ) is a 4-channel, 12-bit sampling Analog-toDigital 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 throughput rate and a +5V supply. The reference voltage (VREF) can be varied between 100mV and VCC, providing a corresponding 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. Low power, high speed, and on-board multiplexer make the ADS7841 ideal for battery-operated systems such as personal digital assistants, portable multi-channel data loggers, and measurement equipment. The serial interface also provides low-cost isolation for remote data acquisition.
