LTC1418AIG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1418AIG#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 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 the specific ordering suffix '#PBF' indicates lead-free finish and RoHS compliance as per manufacturer standards. Confirm the 'I' grade designation matches the required industrial temperature range of –40°C to 85°C for the application environment. Ensure the package type is identified correctly as 28-lead SSOP during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1418AIG#PBF when an industrial temperature range (–40°C to 85°C) is required, distinguishing it from the commercial grade 'C' variant. Choose this model if the design necessitates a 28-lead SSOP package. Consider the integrated 2.5V reference and 4.096V output if external reference components are to be minimized in the schematic.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1418 family of low-power SAR ADCs. The 'A' suffix denotes enhanced linearity specifications compared to standard variants, while 'I' specifies the industrial temperature range. The '#PBF' suffix confirms the lead-free manufacturing process. It is part of Analog Devices' portfolio for general-purpose signal conditioning and data conversion.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1418CG#PBF serves as a direct functional substitute within the same package but operates only in the commercial temperature range (0°C to 70°C). Verify that the reduced temperature specification of the 'C' grade variant meets the environmental constraints of the target application before substitution.
