LTC1418CG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1418CG#TRPBF is a low power, 14-bit, 200ksps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 5V or ±5V supply and features selectable 14-bit parallel or serial data output formats. The device integrates a high-performance sample-and-hold circuit, a precision internal reference, and internal timing logic to minimize external component requirements. Key electrical specifications include ±1.25LSB maximum integral nonlinearity (INL), ±1LSB differential nonlinearity (DNL), and no missing codes over the operating temperature range. Typical AC performance at the Nyquist frequency of 100kHz includes an 81.5dB signal-to-noise plus distortion ratio (S/(N+D)) and –94dB total harmonic distortion (THD).

Analog To Digital Converters (ADC) Feature Summary

• 14-bit resolution with 200ksps sampling rate and no missing codes over temperature.
• Low power consumption of 15mW typical with user-selectable Nap and Sleep shutdown modes.
• Flexible I/O supporting both parallel data output and SPI/MICROWIRE compatible serial interface.
• Integrated 2.5V precision reference and sample-and-hold circuit for simplified design.

Analog To Digital Converters (ADC) Applications

• Remote data acquisition systems
• Battery operated instrumentation
• Digital signal processing applications
• Isolated data acquisition systems
• Medical instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to the tape and reel packaging format as specified in the manufacturer's order information table. Confirm the 'C' grade designation aligns with the required commercial operating temperature range of 0°C to 70°C. Ensure compatibility with the 28-lead SSOP package dimensions for the target PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit SAR ADC with low power dissipation and flexible digital interface options is required. The LTC1418 supports both unipolar (0V to 4.096V) and bipolar (±2.048V) input ranges depending on the supply configuration. Consider the integrated reference and sample-and-hold capabilities if minimizing external bill of materials is a priority.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1418 family of low-power, 14-bit A/D converters. The 'CG' designation indicates the Commercial temperature grade (0°C to 70°C) and the 28-lead Plastic SSOP package. The '#TRPBF' suffix specifies the lead-free finish and Tape & Reel packaging quantity. Other variants in the series include industrial temperature grades and PDIP packages.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices marketing for parts specified with wider operating temperature ranges or alternative package styles such as the obsolete PDIP option.
