LTC2444IUHF#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2444IUHF#TRPBF is a high-speed, 24-bit delta-sigma analog-to-digital converter featuring an 8-channel multiplexer. It supports up to 8 differential or 16 single-ended input channels with selectable speed and resolution combinations. The device operates on a 4.5V to 5.5V supply and utilizes a proprietary architecture for no-latency data output. Key electrical specifications include a maximum integral nonlinearity of 15 ppm of VREF, offset error under 5 µV, and RMS noise ranging from 2 µV at 1.76kHz to 200nV at 13.8Hz. It is housed in a 38-lead QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging. Confirm the 'I' grade designation corresponds to the –40°C to 85°C operating temperature range. Ensure the source document explicitly lists this part number as available from Analog Devices Inc. before procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2444 variant when 8 channels are sufficient; choose LTC2448 for 16 channels. The IUHF suffix denotes the industrial temperature range and QFN package. Consider the LTC2445 if external buffering via MUXOUT/ADCIN pins is required for lower noise performance.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2444/LTC2445/LTC2448/LTC2449 family of 24-bit delta-sigma ADCs. The LTC2444 specifically provides 8 input channels, distinguishing it from the 16-channel LTC2448. All variants share the same QFN-38 footprint and core functionality.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2448IUHF#TRPBF offers identical electrical characteristics but supports 16 channels instead of 8. LTC2445IUHF#TRPBF includes MUXOUT/ADCIN pins for external buffering.
