DESCRIPTION
The ADS8344 is an 8-channel, 16-bit sampling ana-
log-to-digital converter (ADC) 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 , providing a corresponding input voltage
CC
range of 0V to V_REF. The device includes a shutdown
mode which reduces power dissipation to under 15µW.
The ADS8344 is guaranteed down to 2.7V operation.
Low power, high speed, and on-board multiplexer
make the ADS8344 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 ADS8344 is available
in a QSOP-20 or a SSOP-20 package and is guaran-
teed over the –40°C to +85°C temperature range.
