SBAS139E – SEPTEMBER 2000 – REVISED SEPTEMBER 2006

16-Bit, 8-Channel Serial Output Sampling

ANALOG-TO-DIGITAL CONVERTER

DESCRIPTION

FEATURES

ꢀ PIN FOR PIN WITH ADS7844

ꢀ SINGLE SUPPLY: 2.7V to 5V

The ADS8344 is an 8-channel, 16-bit, sampling

Analog-to-Digital (A/D) converter with a synchronous serial

interface. Typical power dissipation is 10mW at a 100kHz

throughput rate and a +5V supply. The reference voltage

(V_REF) can be varied between 500mV and V_CC, providing a

corresponding input voltage range of 0V to V_REF. The

device includes a shutdown mode that reduces power dissi-

pation to under 15µW. The ADS8344 is tested down to 2.7V

operation.

ꢀ 8-CHANNEL SINGLE-ENDED OR

4-CHANNEL DIFFERENTIAL INPUT

ꢀ UP TO 100kHz CONVERSION RATE

ꢀ 84dB SINAD

ꢀ SERIAL INTERFACE

ꢀ QSOP-20 AND SSOP-20 PACKAGES

Low power, high speed, and an on-board multiplexer make

the ADS8344 ideal for battery-operated systems such as

personal digital assistants, portable multi-channel data log-

gers, and measurement equipment. The serial interface also

provides low-cost isolation for remote data acquisition. The

ADS8344 is available in a QSOP-20 or SSOP-20 package

and is ensured over the –40°C to +85°C temperature range.
