Description

The ADS8342 is a 4-channel, 16-bit analog-to-digital converter (ADC). It contains a 16-bit succesive approximation register (SAR), a capacitor-based ADC with an inherent sample-and-hold circuit, an interface for microprocessor use, and parallel 3-state output drivers. It  is specified at a 250kHz sampling rate while dissipating only 200mW of power using a ±5V power supply.

The ADS8342 is available in a TQFP-48 package and is ensured over the 40°C to +85°C temperature range.
