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 VCC 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 – 0.5VREF to 0.5VREF. The reference common
mode voltage, VREFCM, and the input common mode volt-
age, VINCM, may be independently set within GND to VCC.
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.
