The resolution is programmable to either 8 bits or 12 bits. Typical power dissipation is 2m W at a 200k Hz throughput rate and a +5V supply. The reference voltage (VREF) can be varied between 100m V 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. The ADS7841 is available in a DIP-16 or a SSOP-16 package and is specified over the - 40°C to +125°C(1) temperature range. NOTE: (1) ES grade only.
