LTC2421/LTC2422

1-/2-Channel 20-Bit µPower

No Latency ∆Σ^TMADCs in MSOP-10

FEATURES

DESCRIPTIO

■

20-Bit ADCs in Tiny MSOP-10 Packages

TheLTC^®2421/LTC2422are1-and2-channel2.7Vto5.5V

micropower 20-bit analog-to-digital converters with an

integrated oscillator, 8ppm INL and 1.2ppm RMS noise.

■

1- or 2-Channel Inputs

■

Single Supply 2.7V to 5.5V Operation

Low Supply Current (200µA) and Auto Shutdown

■

These ultrasmall devices use delta-sigma technology and

Automatic Channel Selection (Ping-Pong) (LTC2422) anewdigitalfilterarchitecturethatsettlesinasinglecycle.

No Latency: Digital Filter Settles in a

Single Conversion Cycle

8ppm INL, No Missing Codes

4ppm Full-Scale Error

0.5ppm Offset

1.2ppm Noise

Zero Scale and Full Scale Set for Reference

and Ground Sensing

Internal Oscillator—No External Components Required

110dB Min, 50Hz/60Hz Notch Filter

Reference Input Voltage: 0.1V to V_CC

Live Zero—Extended Input Range Accommodates

12.5% Overrange and Underrange

Pin Compatible with LTC2401/LTC2402

This eliminates the latency found in conventional ∆Σ

converters and simplifies multiplexed applications.

■

Through a single pin, the LTC2421/LTC2422 can be

configured for better than 110dB rejection at 50Hz or

60Hz ±2%, or can be driven by an external oscillator for

a user defined rejection frequency in the range 1Hz to

120Hz. The internal oscillator requires no external fre-

quency setting components.

■

These converters accept an external reference voltage

from 0.1V to V_CC. With an extended input conversion

range of –12.5% V_REFto 112.5% V_REF(V_REF= FS_SET

ZS_SET), the LTC2421/LTC2422 smoothly resolve the off-

set and overrange problems of preceding sensors or

signal conditioning circuits.

APPLICATIO S

The LTC2421/LTC2422 communicate through a 2- or

3-wire digital interface that is compatible with SPI and

MICROWIRE^TMprotocols.
