24-Bit No Latency ∆Σ™ ADC

with Differential Input and

Differential Reference

DESCRIPTION

The LTC®2410 is a 2.7V to 5.5V micropower 24-bit dif-

ferential ∆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 LTC2410 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 re-

mote 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 independently set

anywhere within the GND to VCC range of the LTC2410. The

DC common mode input rejection is better than 140dB.

The LTC2410 communicates through a flexible 3-wire

digital interface which is compatible with SPI and MI-

CROWIRE protocols.
