DESCRIPTION
The ADS5102/3 are low-power CMOS, 10-bit, analog-
to-digital converters (ADC) that operate from a single
1.8-V supply. The internal reference can be bypassed
to use an external reference to suit the dc accuracy and
temperature drift requirements of the application. A
10-bit parallel output data bus is provided with 3-state
outputs. For power sensitive systems, a standby mode
is provided which reduces power consumption to
336
W. Also, if using external voltage reference, then
the internal VREF circuit can be powered down. The
analog input is differential, which provides excellent
common-mode noise rejection as well as superior
performance from the ADS5102/3.
