APPLICATIU
FEATURES
DESCRIPTIOU
The LTC
2414/LTC2418 are 8-/16-channel (4-/8-differ-
ential) micropower 24-bit
Σ
analog-to-digital convert-
ers. They operate from 2.7V to 5.5V and include an
integrated oscillator, 2ppm INL and 0.2ppm RMS noise.
They use delta-sigma technology and provide single cycle
settling time for multiplexed applications. Through a
single pin, the
LTC2414/LTC2418
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 LTC2414/LTC2418 accept any external differential
reference voltage from 0.1V to V
CC
for flexible ratiometric
and remote sensing measurement applications. They can
be configured to take 4/8 differential channels or
8/16 single-ended channels. The full-scale bipolar input
range is from –0.5V
REF
to 0.5V
REF
. The reference common
mode voltage, V
REFCM
, and the input common mode volt-
age, V
INCM
, may be independently set within GND to V
CC
.
The DC common mode input rejection is better than 140dB.
The LTC2414/LTC2418 communicate through a flexible
4-wire digital interface that is compatible with SPI and
MICROWIRE
TM
protocols.
