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

µW. 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.
