LTC1419CG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1419CG#PBF is a 14-bit, 800ksps sampling analog-to-digital converter (ADC) utilizing a successive approximation register (SAR) architecture. It operates from ±5V supplies with a typical power dissipation of 150mW. The device features true differential inputs with a ±2.5V range and includes an internal 2.5V reference. Key performance metrics include 81.5dB S/(N+D), 93dB THD, and 95dB SFDR at a 100kHz input frequency. It offers two shutdown modes: Nap and Sleep. The component is housed in a 28-lead SOIC package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the CG suffix corresponds to the commercial temperature range (0°C to 70°C). Ensure the 28-pin SOIC package matches the PCB footprint requirements. Cross-reference the manufacturer's latest documentation for any pinout or electrical specification updates.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range and low distortion at moderate sampling speeds. The SAR architecture eliminates pipeline delay, making it suitable for burst-mode acquisitions. Consider the 20MHz full-power bandwidth for undersampling wideband signals. Verify that the parallel interface timing meets the system's microprocessor or DSP requirements.

Analog To Digital Converters (ADC) Part Context

The LTC1419 is part of the Linear Technology ADC family, serving as a higher-resolution alternative to the 12-bit LTC1410. It shares similar functional characteristics but provides improved dynamic performance with 14-bit accuracy. The device is designed to replace older generation converters in instrumentation and communication equipment requiring precise signal digitization.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same series include the LTC1419ACG#PBF (A-grade) and LTC1419IG#PBF (I-grade). Other variants such as the SSOP package versions (LTC1419CSW#PBF) offer different form factors but identical functionality. Ensure thermal management aligns with the specific package's junction-to-ambient resistance.
