TM

analog-to-digital converter with an inte-

grated oscillator. It provides 0.12LSB INL and 1.45碌V

RMS noise independent of V

REF

. It uses delta-sigma

technology and provides single conversion settling of the

digital filter. Through a single pin, the LTC2433-1 can be

configured for better than 87dB input differential mode

rejection at 50Hz and 60Hz

卤2%,

or it can be driven by an

external oscillator for a user defined rejection frequency.

The internal oscillator requires no external frequency

setting components.

The converter accepts any external differential reference

voltage from 0.1V to V

CC

for flexible ratiometric and

remote sensing measurement configurations. The full-

scale differential input range is from 鈥?0.5 鈥?V

, and

the input common mode voltage, V

, may be indepen-

dently set anywhere between GND and V

CC

. The DC

common mode input rejection is better than 140dB.

The LTC2433-1 communicates through a flexible 3-wire

digital interface which is compatible with SPI and
