APPLICATIOU
The LTC
2415/2415-1 are micropower 24-bit differential
Σ
analog to digital converters with integrated oscillator,
2ppm INL, 0.23ppm RMS noise and a 2.7V to 5.5V supply
range. They use delta-sigma technology and provide
single cycle settling time for multiplexed applications.
Through a single pin, the LTC2415 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
LTC2415-1 can be configured for better than 87dB input
differential mode rejection over the range of 49Hz to
61.2Hz (50Hz and 60Hz
±
2% simultaneously). The inter-
nal oscillator requires no external frequency setting com-
ponents.
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
LTC2415/LTC2415-1. The DC common mode input rejec-
tion is better than 140dB.
The LTC2415/LTC2415-1 communicate through a flexible
3-wire digital interface which is compatible with SPI and
MICROWIRE
TM
protocols.
