DESCRIPTION

The ADS8344 is an 8-channel, 16-bit sampling analog-to-digital converter (ADC) with a synchronous serial interface.

Typical power dissipation is 10mW at a 100kHz throughput rate and a +5V supply.

The reference voltage (VREF) can be varied between 500mV 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 ADS8344 is guaranteed down to 2.7V operation.

Low power, high speed, and on-board multiplexer make the ADS8344 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 ADS8344 is available in a QSOP-20 or a SSOP-20 package and is guaranteed over the –40°C to +85°C temperature range.
