Description

General part information

LTC2401 Series

The LTC2401/LTC2402 are 1- and 2-channel 2.7V to 5.5V micropower 24-bit analog-to-digital converters with an integrated oscillator, 4ppm INL and 0.6ppm RMS noise. These ultrasmall devices use delta-sigma technology and a new digital filter architecture that settles in a single cycle. This eliminates the latency found in conventional ΔΣ converters and simplifies multiplexed applications.Through a single pin, the LTC2401/LTC2402 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 frequency setting components.These converters accept an external reference voltage from 0.1V to VCC. With an extended input conversion range of –12.5% VREFto 112.5% VREF(VREF= FSSET– ZSSET), the LTC2401/LTC2402 smoothly resolve the offset and overrange problems of preceding sensors or signal conditioning circuits.The LTC2401/LTC2402 communicate through a 2- or 3-wire digital interface that is compatible with SPI and MICROWIRE™protocols.ApplicationsWeight ScalesDirect Temperature MeasurementGas AnalyzersStrain-Gage TransducersInstrumentationData AcquisitionIndustrial Process Control
