LTC2430/LTC2431

24301f
The LTC
2430/LTC2431 are 2.7V to 5.5V micropower
20-bit differential
Σ analog-to-digital converters with an
integrated oscillator, 3ppm INL and 0.56ppm RMS noise.
They use delta-sigma technology and provide single cycle
settling time for multiplexed applications. Through a
single pin, the LTC2430/LTC2431 can be configured for
better than 110dB differential mode rejection at 50Hz or
60Hz
±2%, or they can be driven by an external oscillator
for a user-defined rejection frequency. The internal oscil-
lator requires no external frequency setting components.
The converters accept any external differential reference
voltage from 0.1V to VCC for flexible ratiometric and
remote sensing measurement configurations. The full-
scale differential input range is from – 0.5VREF to 0.5VREF.
The reference common mode voltage, VREFCM, and the
input common mode voltage, VINCM, may be indepen-
dently set anywhere within GND to VCC. The DC common
mode input rejection is better than 120dB.
The LTC2430/LTC2431 communicate through a flexible
3-wire digital interface that is compatible with SPI and
MICROWIRE
TM protocols.
