Analog To Digital Converters (ADC) datasheet and documents for LTC2445IUHF#TRPBF

LTC2445IUHF#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2445IUHF#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 modes with no latency between conversions. The device operates on a single 4.5V to 5.5V supply and includes MUXOUT/ADCIN pins for external buffering. Key electrical specifications include 2µVRMS noise at 1.76kHz output rate, 200nVRMS noise at 13.8Hz with simultaneous 50Hz/60Hz rejection, and 0.0005% INL without missing codes.

Analog To Digital Converters (ADC) Feature Summary

16 Single-Ended or 8 Differential Input Channels
No Latency Mode with Variable Speed/Resolution
MUXOUT/ADCIN Pins for External Buffering
Internal Oscillator with No External Components Required

Analog To Digital Converters (ADC) Applications

High Speed Multiplexing
Weight Scales
Auto Ranging 6-Digit DVMs
Direct Temperature Measurement

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering 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 38-lead QFN footprint matches the PCB design requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC2444 when external buffering is required via dedicated MUXOUT/ADCIN pins. Choose the 'I' grade variant for industrial temperature applications (-40°C to 85°C). Verify that the 4.5V to 5.5V supply voltage range aligns with the system power architecture.

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 LTC2445 specifically provides 16 single-ended inputs and includes pins for external multiplexer buffering, distinguishing it from the LTC2444 which lacks these specific buffer interface pins.
