LTC2445CUHF#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2445CUHF#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 and resolution with no latency between conversions. The device operates on a 4.5V to 5.5V supply and includes MUXOUT/ADCIN pins for external buffering. Noise performance ranges from 2µVRMS at 1.76kHz to 200nVRMS at 13.8Hz. It guarantees modulator stability and offers an autosleep mode for low power consumption.

Analog To Digital Converters (ADC) Feature Summary

• 16 Single-Ended or 8 Differential Input Channels
• Up to 8kHz Output Rate with Selectable Speed/Resolution
• No Latency Mode Ensures Accurate Data After Channel Selection
• MUXOUT/ADCIN Pins Enable External Buffering or Gain

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 'C' grade designation corresponds to the 0°C to 70°C operating temperature range. Ensure the specific lot matches the required lead-free finish specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC2444 when 16 single-ended channels are required instead of 8 differential. Choose the 'I' grade variant if operation below 0°C or above 70°C is necessary. Verify that the external buffer requirements align with the dedicated MUXOUT and ADCIN pin configurations.

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 primary distinction of the LTC2445 within this group is its provision of 16 single-ended or 8 differential input channels, whereas other members may offer different channel counts or lack the external buffering pins.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2444CUHF#TRPBF: Offers 8 differential inputs but lacks MUXOUT/ADCIN pins. LTC2448CUHF#TRPBF: Provides 16 single-ended inputs but lacks MUXOUT/ADCIN pins. LTC2449CUHF#TRPBF: Identical functionality to LTC2445 but available in industrial temperature grade (-40°C to 85°C).
