LTC2508IDKD-32#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2508IDKD-32#TRPBF is a 32-bit oversampling ADC featuring an integrated configurable digital filter. It operates from a single 2.5V supply with a reference voltage range of 2.5V to 5.1V. The device provides two simultaneous outputs: a 32-bit digitally filtered low-noise code and a 22-bit no-latency composite code (14-bit differential, 8-bit common mode). Key electrical parameters include a maximum sampling frequency of 1Msps, a dynamic range of up to 145dB at 61sps, and typical integral nonlinearity of ±0.5ppm. It utilizes a 24-lead 7mm × 4mm DFN package and supports SPI-compatible serial I/O.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging. Confirm the ID suffix corresponds to the industrial temperature range of –40°C to 85°C. Ensure compatibility with the 24-lead DFN footprint during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring high precision and low noise without external filtering. Choose based on the required down-sampling factor via SEL0/SEL1 pins. Ensure the host interface voltage matches the OVDD range of 1.71V to 5.25V for proper logic level compatibility.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2508 family of 32-bit SAR ADCs. It shares architectural similarities with the LTC2500-32 but offers higher sampling rates. The part is designed for high-performance data acquisition systems requiring precise analog-to-digital conversion.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2508CDKD-32#TRPBF differs only in operating temperature range (0°C to 70°C). LTC2500-32 variants offer similar functionality with different sampling rate specifications.
