LTC1418CN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1418CN#PBF is a low power, 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It supports a sampling rate of 200ksps and operates from a single +5V or ±5V supply. The device features selectable 14-bit parallel or serial data output formats. Key electrical specifications include ±1.25LSB maximum integral nonlinearity (INL), ±1LSB maximum differential nonlinearity (DNL), and typical power dissipation of 15mW. It incorporates an onboard sample-and-hold circuit, precision reference, and internal timing to minimize external component requirements.

• ±1.25LSB INL and ±1LSB DNL max over temperature

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type for the CN suffix, which corresponds to a 28-lead narrow PDIP. Confirm that the C suffix meets the required commercial operating temperature range of 0°C to 70°C. Ensure the #PBF designation indicates lead-free finish compliance. Cross-reference the specific order code against current manufacturer availability as packaging options may vary.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit SAR ADC with flexible I/O is required. Choose the CN package if through-hole mounting is necessary; otherwise, consider the CG variant for surface mount applications. Verify that the input voltage range (0V to 4.096V unipolar or ±2.048V bipolar) matches the system design. Ensure the driving source impedance is managed to meet the 1µs acquisition time requirement at full throughput.

Analog To Digital Converters (ADC) Part Context

The LTC1418 belongs to the Linear Technology (now Analog Devices) family of low-power, high-speed ADCs. It is designed to replace older parallel-only converters by offering versatile serial interface capabilities alongside traditional parallel outputs. The device integrates functions typically requiring multiple discrete components, such as the reference and clock generator, into a single monolithic IC.
