DESCRIPTION
The ADS8341 is a 4-channel, 16-bit sampling Analog-to-
Digital (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, providing a corresponding
input voltage range of 0V to VREF. The device includes a
shutdown mode that reduces power dissipation to under
15μW. The ADS8341 is tested down to 2.7V operation.
Low power, high speed, and an onboard multiplexer make
the ADS8341 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
ADS8341 is available in an SSOP-16 package and is ensured
over the –40°C to +85°C temperature range.
