The LTC
2435/2435-1 are 2.7V to 5.5V micropower
20-bit differential
Σ
analog to digital converters with
integrated oscillator, 3ppm INL and 0.8ppm RMS noise.
They use delta-sigma technology and provide single cycle
settling time for multiplexed applications. Through a
single pin, the LTC2435 can be configured for better than
110dB input differential mode rejection at 50Hz or 60Hz
±
2%, or it can be driven by an external oscillator for a user
defined rejection frequency. The LTC2435-1 can be con-
figured for better than 87dB input differential mode rejec-
tion over the range of 49Hz to 61.2Hz (50Hz and 60Hz
±
2% simultaneously). The internal oscillator requires no
external frequency setting components.
The converters accept 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 –0.5V
REF
to 0.5V
REF
.
The reference common mode voltage, V
REFCM
, and the
input common mode voltage, V
INCM
, may be indepen-
dently set anywhere within the GND to V
CC
range of the
LTC2435/LTC2435-1. The DC common mode input rejec-
tion is better than 120dB.
The LTC2435/LTC2435-1 communicate through a flexible
3-wire digital interface which is compatible with SPI and
MICROWIRE
TM
protocols.
