Overview
The ADS8344NB/1KG4 is an 8-channel, 16-bit, sampling Analog-to-Digital (A/D) converter produced by Texas Instruments. It features a synchronous serial interface and operates from a single supply voltage ranging from 2.7V to 5.25V. The device is designed for low power consumption, with a typical power dissipation of 10mW at a 100kHz throughput rate and a +5V supply. It includes a shutdown mode that reduces power dissipation to under 15µW, making it ideal for battery-operated systems.
