Overview
The ADS8344NB, produced by Texas Instruments, is an 8-channel, 16-bit, sampling Analog-to-Digital (A/D) converter. It is designed with low power consumption, high speed, and an on-board multiplexer, making it ideal for battery-operated systems. The device operates on a single supply voltage ranging from 2.7V to 5V and features a synchronous serial interface. Typical power dissipation is 10mW at a 100kHz throughput rate and a +5V supply. The ADS8344NB is available in QSOP-20 and SSOP-20 packages and is ensured over the -40°C to +85°C temperature range.
