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.
