ADS7841

The ADS7841 is a 4-channel, 12-bit sampling analogto-digital converter (ADC) with a synchronous serial interface. The resolution is programmable to either 8 or 12 bits. Typical power dissipation is 2mW at a 200kHz throughput 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 15µW. The ADS7841 is guaranteed 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 multichannel data loggers, and measurement equipment. The serial interface also provides low-cost isolation for remote data acquisition. The ADS7841 is available in a 16-pin PDIP or a 16-lead SSOP package and is guaranteed over the 40°C to +85°C temperature range.
