Analog To Digital Converters (ADC) datasheet and documents for LTC2449CUHF#TRPBF

LTC2449CUHF#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2449CUHF#TRPBF is a 24-bit, 16-channel (8-differential) delta-sigma analog-to-digital converter in a 38-lead QFN package. It features selectable speed/resolution combinations ranging from 6.9Hz to 3.5kHz with no latency between conversions. The device operates on a 4.5V to 5.5V supply, drawing 8mA during conversion and 30µA in sleep mode. Key electrical characteristics include 2µVRMS noise at 1.76kHz output rate, 0.0005% INL, and <5µV offset error over the commercial temperature range of 0°C to 70°C.

Analog To Digital Converters (ADC) Feature Summary

16 Single-Ended or 8 Differential Input Channels
No Latency Delta-Sigma Architecture for High-Speed Multiplexing
Selectable Speed/Resolution: 6.9Hz to 3.5kHz Output Rates
MUXOUT/ADCIN Pins for External Buffering or Gain Stages

Analog To Digital Converters (ADC) Applications

High Speed Data Acquisition Systems
Direct Temperature Measurement with Thermocouples and RTDs
Auto Ranging 6-Digit Digital Voltmeters
Weigh Scales

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'C' suffix indicates the commercial temperature range (0°C to 70°C). Confirm the '#TRPBF' suffix denotes tape and reel packaging. Ensure the source document explicitly lists this specific part number as available, noting that distribution status may vary by region.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2449 over the LTC2448 when external buffering or gain stages are required between the multiplexer and ADC input. Choose the 'I' suffix variant if operation below 0°C or above 85°C is necessary. Verify that the 16-channel single-ended configuration meets system requirements, as the LTC2448 offers the same pinout without MUXOUT pins.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2444/LTC2445/LTC2448/LTC2449 family of high-speed, no-latency delta-sigma ADCs. The LTC2449 specifically provides 16 channels and includes dedicated MUXOUT/ADCIN pins to facilitate external signal conditioning, distinguishing it from the LTC2448 which lacks these outputs.
