ANALOG-TO-DIGITAL CONVERTER
FEATURES
DESCRIPTION
q BIPOLAR INPUT RANGE
The ADS8343 is a 4-channel, 16-bit sampling Analog-toDigital (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.
q PIN-FOR-PIN COMPATIBLE WITH THE
ADS7841 AND ADS8341
q SINGLE SUPPLY: 2.7V to 5V
q 4-CHANNEL SINGLE-ENDED OR
2-CHANNEL DIFFERENTIAL INPUT
q UP TO 100kHz CONVERSION RATE
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.
