LTC1419ACSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1419ACSW#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 range and 20MHz full-power bandwidth. Key performance metrics include an 81.5dB signal-to-(noise + distortion) ratio at 100kHz input and a spurious-free dynamic range of 93dB. It integrates a 2.5V internal reference and offers two shutdown modes for low-power applications.

Analog To Digital Converters (ADC) Feature Summary

• Differential inputs reject common mode noise with 60dB CMRR
• Integrated 2.5V precision reference with 15ppm/°C temperature coefficient
• Nap and Sleep shutdown modes reduce power consumption to 1.2mW

Analog To Digital Converters (ADC) Applications

• Telecommunications systems
• Multiplexed data acquisition systems
• Spectrum analysis equipment
• Imaging systems requiring high-speed sampling

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates a lead-free tape and reel packaging configuration. Confirm the ACSW designation corresponds to the commercial temperature range (0°C to 70°C) and SOIC-28 package. Ensure compatibility with ±5V supply requirements and parallel digital interface constraints during procurement validation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit SAR ADC with integrated reference and differential inputs is required. The 800ksps throughput supports Nyquist frequencies up to 400kHz. Consider the 150mW power dissipation for thermal management. Verify that the microprocessor interface can handle the parallel data bus and control signals (CONVST, CS, RD, BUSY).

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1419 family of high-speed, low-power sampling A/D converters. The 'A' grade denotes tighter linearity specifications compared to the standard 'C' grade. The 'SW' suffix identifies the 28-lead plastic SOIC package option. The '#TRPBF' suffix specifies the lead-free tape and reel shipping format.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other Analog Devices SAR ADCs with similar resolution and sampling rates if direct replacement is necessary.
