16-Bit, 4-Channel Serial Output Sampling Analog-To-Digital Converter - ADS8343

ADS8343 (ACTIVE)

16-Bit, 4-Channel Serial Output Sampling Analog-To-Digital Converter

 

Description

The ADS8343 is a 4-channel, 16-bit sampling Analog-to-Digital (A/D) converter with a synchronous serial interface. Typical power dissipation is 8mW at a 100kHz throughput rate and a +5V supply. The reference voltage (VREF) can be varied between 500mV and VCC/2, providing a corresponding input voltage range of ±VREF. The device includes a shutdown mode which reduces power dissipation to under 15µW. The ADS8343 is ensured down to 2.7V operation.

Low power, high speed, and an onboard multiplexer make the ADS8343 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 ADS8343 is available in an SSOP-16 package and is ensured over the –40°C to +85°C temperature range.
