LTC2415/LTC2415-1

24-Bit No Latency ∆Σ^TM

ADCs with Differential Input and

Differential Reference

DESCRIPTIO

FEATURES

The LTC^®2415/2415-1 are micropower 24-bit differential

∆Σ analog to digital converters with integrated oscillator,

2ppmINL, 0.23ppmRMSnoiseanda2.7Vto5.5Vsupply

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.

(SO-8 Footprint)

Single Supply 2.7V to 5.5V Operation

The converters accept any external differential reference

voltage from 0.1V to V_CCfor flexible ratiometric and

remote sensing measurement configurations. The full-

■

^{Low Supply Curr}U^{ent (200µA) and Auto Shutdown}

scale differential input range is from –0.5V_REFto 0.5V_REF

APPLICATIO S

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_CCrange of the

LTC2415/LTC2415-1. The DC common mode input rejec-

tion is better than 140dB.
