The LTC
2401/LTC2402 are 1- and 2-channel 2.7V to
5.5V micropower 24-bit analog-to-digital converters with
an integrated oscillator, 4ppm INL and 0.6ppm RMS
noise. These ultrasmall devices use delta-sigma technol-
ogy and a new digital filter architecture that settles in a
single cycle. This eliminates the latency found in conven-
tional
Σ
converters and simplifies multiplexed applica-
tions.
Through a single pin, the LTC2401/LTC2402 can be
configured for better than 110dB rejection at 50Hz or
60Hz
±
2%, or can be driven by an external oscillator for
a user defined rejection frequency in the range 1Hz to
120Hz. The internal oscillator requires no external fre-
quency setting components.
These converters accept an external reference voltage
from 0.1V to V
CC
. With an extended input conversion
range of –12.5% V

), the LTC2401/LTC2402 smoothly resolve the off-
set and overrange problems of preceding sensors or
signal conditioning circuits.
The LTC2401/LTC2402 communicate through a 2- or
3-wire digital interface that is compatible with SPI and
MICROWIRE
TM
protocols.
