ADS7841 - 12-bit 4-channel serial output sampling analog-to-digital converter (ADC)

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 (V_REF) can be varied between 100mV and V_CC, providing a corresponding input voltage range of 0V to V_REF. The device includes a shutdown mode which reduces power dissipation to under 15uW. 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 \x9640°C to +125°C ⁽¹⁾ temperature range.
