Overview

24-Bit ADC in an MS10 Package
Low Supply Current (200µA in Conversion Mode and 4µA in Autosleep Mode)
Differential Input and Differential Reference with GND to V_CC Common Mode Range
2ppm INL, No Missing Codes
4ppm Full-Scale Error and 1ppm Offset
0.29ppm Noise
No Latency: Digital Filter Settles in a Single Cycle. Each Conversion Is Accurate, Even After an Input Step
Single Supply 2.7V to 5.5V Operation
Internal Oscillator—No External Components Required
110dB Min, Pin Selectable 50Hz/60Hz Notch Filter (LTC2411)
Simultaneous 50Hz/60Hz Rejection (LTC2411-1)

The LTC2411/LTC2411-1 are 2.7V to 5.5V micropower 24-bit differential ∆Σ analog-to-digital converters with an integrated oscillator, 2ppm INL and 0.29ppm RMS noise. They use delta-sigma technology and provide single cycle settling time for multiplexed applications. Through a single pin, the LTC2411 can be configured for better than 110dB differential mode rejection at 50Hz or 60Hz ±2%, and the LTC2411-1 can provide better than 87dB input differential mode rejection over the range of 49Hz to 61.2Hz, or they can be driven by an external oscillator for a user-defined rejection frequency. The LTC2411 and LTC2411-1 are identical when driven by an external oscillator. The internal oscillator requires no external frequency setting components.

The converters accept any external differential reference voltage from 0.1V to V_CC for flexible ratiometric and remote 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_CC range of the LTC2411/LTC2411-1. The DC common mode input rejection is better than 140dB.

The LTC2411/LTC2411-1 communicate through a flexible 3-wire digital interface that is compatible with SPI and MICROWIRE protocols.
