ADS8343 ADS8 343 SBAS183A – JANUARY 2001 – REVISED OCTOBER 2002 16-Bit, 4-Channel Serial Output Sampling ANALOG-TO-DIGITAL CONVERTER FEATURES q BIPOLAR INPUT RANGE 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 q 86dB SINAD q SERIAL INTERFACE q SSOP-16 PACKAGE DESCRIPTION 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. 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.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
