LTC1418ACN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1418ACN#PBF is a low power, 14-bit, 200ksps Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc. It features selectable serial or parallel data output formats and operates from a single 5V or ±5V supply. The device integrates a high-performance sample-and-hold circuit, a precision reference, and internal timing logic to minimize external component requirements. Key electrical specifications include ±1.25LSB maximum Integral Nonlinearity (INL), ±1LSB maximum Differential Nonlinearity (DNL), and no missing codes over the operating temperature range. Typical power dissipation is 15mW.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the specific part number corresponds to the commercial grade (0°C to 70°C) variant. Confirm the package type matches the 'CN' suffix designation for a 28-lead Plastic DIP. Ensure compatibility with existing board layouts regarding pin count and footprint dimensions before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit resolution and 200ksps throughput are required with minimal power consumption. Choose the ACN variant specifically if through-hole mounting via a 28-lead PDIP package is necessary. Consider the CG variant if surface mount assembly is preferred. Verify input voltage ranges match the system's unipolar (0V to 4.096V) or bipolar (±2.048V) requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1418 family of low-power SAR ADCs. The ACN suffix indicates the Commercial temperature grade (0°C to 70°C) and the N package style (28-Lead Plastic DIP). Other variants in the series include the Industrial grade parts (e.g., LTC1418AIN#PBF) and Surface Mount packages (e.g., LTC1418ACG#PBF in SSOP).

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same package and grade include other LTC1418 variants such as LTC1418ACN#TRPBF (Tape & Reel) or LTC1418CGN#PBF (Commercial Grade, different performance bin). Cross-package replacements like the LTC1418ACG#PBF require PCB redesign.
