The LTC
2412 is a 2-channel differential input micropower
24-bit No Latency
ΣTM analog-to-digital converter with
an integrated oscillator. It provides 2ppm INL and 0.16ppm
RMS noise over the entire supply range. The two differen-
tial channels are converted alternately with channel ID
included in the conversion results. It uses delta-sigma
technology and provides single conversion settling of the
digital filter. Through a single pin, the LTC2412 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 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. The DC
common mode input rejection is better than 140dB.
The LTC2412 communicates through a flexible 3-wire
digital interface which is compatible with SPI and
MICROWIRE
TM protocols.
