LTC1418AIG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1418AIG#TRPBF is a low power, 14-bit successive approximation analog-to-digital converter (ADC) with selectable serial and parallel I/O. It operates from a single 5V or ±5V supply at sampling rates up to 200ksps. The device features an onboard high-performance sample-and-hold circuit, a precision reference, and internal timing. DC specifications include ±1.25LSB maximum integral nonlinearity (INL), ±1LSB maximum differential nonlinearity (DNL), and no missing codes over the industrial temperature range of –40°C to 85°C. Power dissipation is typically 15mW in unipolar mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging. Confirm the 'I' grade designation corresponds to the –40°C to 85°C operating temperature range. Ensure compatibility with the 28-lead SSOP package dimensions for PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power and high accuracy at moderate speeds. The serial interface reduces pin count compared to parallel-only options. Verify input voltage ranges match system requirements: 0V to 4.096V for single 5V supply or ±2.048V for dual ±5V supplies.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1418 family of low-power SAR ADCs. The 'A' grade specifies tighter linearity and offset error limits compared to the standard 'C' grade. The 'I' suffix denotes the industrial temperature rating, while 'G' indicates the 28-lead SSOP plastic package.
