16-Bit, 100-kSPS, 8-Ch SAR ADC with single-ended inputs

The ADS8344 is an 8-channel, 16-bit, sampling Analog-to-Digital (A/D) converter 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 that reduces power dissipation to under 15µW. The ADS8344 is tested down to 2.7V operation.

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