Final Electrical Specifications

LTC2410

24-Bit No Latency ∆Σ^TMADC

with Differential Input and

Differential Reference

April 2000

DESCRIPTIO

FEATURES

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

differential ∆Σ analog to digital converter with an inte-

grated 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%, oritcanbedrivenbyanexternaloscillatorforauser

defined rejection frequency. The internal oscillator re-

quires no external frequency setting components.

■

Single Supply 2.7V to 5.5V Operation

scale differential input range is from –0.5V_REFto 0.5V_REF

■

Low Supply Current (200µA) and Auto Shutdown

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

LTC2410. The DC common mode input rejection is better

than 140dB.
