sn2413 2413fs
The LTC
2413 is a 2.7V to 5.5V simultaneous 50Hz/60Hz
rejection micropower 24-bit differential
Σ analog to
digital converter with an integrated oscillator, 2ppm INL
and 0.16ppm RMS noise. It uses delta-sigma technology
and provides single cycle settling time for multiplexed
applications. Through a single pin, the LTC2413 can be
configured for better than 87dB input differential mode
rejection over the range of 49Hz to 61.2Hz (50Hz and
60Hz
±2% simultaneously), or it can be driven by an
external oscillator for a user defined rejection frequency.
The internal oscillator requires no external frequency
setting components.
The converter accepts any external differential reference
voltage from 0.1V to VCC for flexible ratiometric and
remote sensing measurement configurations. The full-
scale differential input range is from – 0.5VREF to 0.5VREF.
The reference common mode voltage, VREFCM, and the
input common mode voltage, VINCM, may be indepen-
dently set anywhere within the GND to VCC range of the
LTC2413. The DC common mode input rejection is better
than 140dB.
The LTC2413 communicates through a flexible 3-wire
digital interface which is compatible with SPI and
MICROWIRE
TM protocols.
