DESCRIPTION
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
(VREF) can be varied between 500mV and VCC, providing a
corresponding input voltage range of 0V to VREF. The
device includes a shutdown mode that reduces power dissipation
to under 15μW. The ADS8344 is tested down to 2.7V
operation.
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 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 SSOP-20 package
and is ensured over the –40°C to +85°C temperature range.
