ADS8343

SBAS183A – JANUARY 2001 – REVISED OCTOBER 2002

16-Bit, 4-Channel Serial Output Sampling ANALOG-TO-DIGITAL CONVERTER

FEATURES DESCRIPTION

BIPOLAR INPUT RANGE

The ADS8343 is a 4-channel, 16-bit sampling Analog-to- PIN-FOR-PIN COMPATIBLE WITH THE Digital (A/D) converter with a synchronous serial interface. ADS7841 AND ADS8341 Typical power dissipation is 8m W at a 100k Hz throughput rate and a +5V supply. The reference voltage (VREF) can be

SINGLE SUPPLY: 2.7V to 5V

varied between 500m V and VCC/2, providing a corresponding

4-CHANNEL SINGLE-ENDED OR

input voltage range of ±VREF. The device includes a shut-

2-CHANNEL DIFFERENTIAL INPUT

down mode which reduces power dissipation to under 15µW. UP TO 100k Hz CONVERSION RATE The ADS8343 is ensured down to 2.7V operation. 86d B SINAD Low power, high speed, and an onboard multiplexer make the ADS8343 ideal for battery-operated systems such as
