LTC2341IUH-16#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2341IUH-16#TRPBF is a dual, 16-bit, 666ksps/ch differential SoftSpan ADC in a 32-lead QFN package. It features simultaneous sampling channels with wide common mode input ranges (0V to VDD) and 105dB CMRR. The device supports per-channel configurable input ranges including ±4.096V, 0V to 4.096V, ±2.048V, and 0V to 2.048V. It integrates a 4.096V reference and buffer, offering ±1.25LSB INL, no missing codes at 16 bits, and 93.4dB SNR. Digital interfaces include pin-selectable SPI CMOS (1.8V to 5V) and LVDS. Operating from a 5V supply, it dissipates 74mW typically and functions up to 125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix #TRPBF indicates tape and reel packaging for the I-grade (-40°C to 85°C) variant. Confirm the 32-lead QFN (5mm x 5mm) package matches board layout requirements. Ensure OVDD voltage levels align with the selected digital interface mode (CMOS or LVDS) before ordering.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring dual-channel simultaneous sampling with flexible input voltage ranges. The I-grade temperature range (-40°C to 85°C) suits standard industrial environments. Choose between CMOS or LVDS digital outputs based on system noise immunity and trace length constraints. Verify that the 5V analog supply and compatible digital logic levels are available.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2341-16 family of dual-channel SoftSpan ADCs. The 'I' suffix denotes the industrial temperature grade (-40°C to 85°C), while 'UH' specifies the 32-lead QFN package. The '#TRPBF' suffix indicates lead-free finish and tape-and-reel shipping format. It shares core architecture with C-grade (commercial) and H-grade (high temp) variants.

Analog To Digital Converters (ADC) Replacement Considerations

For equivalent performance, consider the LTC2341CUH-16#TRPBF for commercial temperature range or LTC2341HUH-16#TRPBF for high-temperature operation. These parts share identical pinouts and electrical specifications but differ only in operating temperature limits.
