FEATURES

LTC2415/LTC2415-1

24-Bit No Latency

∆Σ

™

ADCs with Differential Input and

Differential Reference

DESCRIPTION

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 internal oscillator requires no

external frequency setting components.

The converters accept any external differential reference

voltage from 0.1V to V

for flexible ratiometric and re-

mote 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 independently set

anywhere within the GND to V

range of the LTC2415/

LTC2415-1. The DC common mode input rejection is

better than 140dB.

The LTC2415/LTC2415-1 communicate through a flexible

3-wire digital interface which is compatible with SPI and

MICROWIRE protocols.
