The LTC
2411 is a 2.7V to 5.5V micropower 24-bit
differential
Σ
analog to digital converter with an inte-
grated oscillator, 4ppm INL and 0.29ppm RMS noise. It
uses delta-sigma technology and provides single cycle
settling time for multiplexed applications. Through a
single pin, the LTC2411 can be configured for better than
110dB differential mode rejection at 50Hz or 60Hz
±
2%,
or it can be driven by an external oscillator for a user
defined rejection frequency. The internal oscillator re-
quires 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 –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
LTC2411. The DC common mode input rejection is better
than 140dB.
The LTC2411 communicates through a flexible 3-wire
digital interface which is compatible with SPI and
MICROWIRE
TM
protocols.
