LTC1419CSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1419CSW#TRPBF is a 14-bit, 800ksps successive approximation register (SAR) analog-to-digital converter in a 28-lead SOIC package. It operates from ±5V supplies with a typical power dissipation of 150mW. The device features a true differential input sample-and-hold with a ±2.5V bipolar range and a 20MHz full-power bandwidth. Key performance metrics include an 81.5dB signal-to-(noise + distortion) ratio at 100kHz input and 93dB total harmonic distortion. It integrates a 2.5V internal reference and offers two shutdown modes: nap and sleep.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging and lead-free compliance. Confirm the CS variant meets the required operating temperature range of 0°C to 70°C. Ensure the 28-lead SOIC package dimensions align with the target PCB footprint. Check for RoHS directive compliance documentation if required by local regulations.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high dynamic range ADC with differential inputs is required. The 14-bit resolution and 800ksps speed suit applications needing accurate conversion of wideband signals. Consider the integrated reference if external voltage references are undesirable. Evaluate the shutdown current requirements against system power budgets.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1419 family of 14-bit SAR ADCs. Variants include the CG/G packages and I-grade parts for extended temperature ranges. The SW suffix denotes the 28-lead plastic SOIC package. The TRPBF suffix specifies tape and reel delivery and lead-free manufacturing.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include LTC1419CG#TRPBF (SSOP package) or LTC1419ISW#TRPBF (extended temperature). Verify package outline differences and thermal characteristics when substituting.
