LTC1418IG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1418IG#TRPBF is a low power, 14-bit, 200ksps Analog-to-Digital Converter (ADC) from Analog Devices. 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 Differential Nonlinearity (DNL), and no missing codes over the operating temperature range. Power dissipation is typically 15mW, supported by two user-selectable shutdown modes.

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 'I' grade designation matches the required industrial temperature range of –40°C to 85°C for the specific application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit SAR ADC with flexible digital interface options is required. Ensure the analog input signal falls within the 0V to 4.096V unipolar or ±2.048V bipolar ranges. Verify that the driving source impedance allows for the specified 1µs acquisition time at 200ksps throughput, or utilize an external buffer amplifier if necessary.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1418 family of low-power, 14-bit A/D converters. The 'IG' suffix indicates the Industrial temperature grade (-40°C to 85°C) and the SSOP-28 package. The '#TRPBF' suffix denotes the lead-free finish and Tape & Reel packaging configuration.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1419 is a higher-speed variant offering 800ksps sampling. For lower speed requirements, the LTC1418ACG#PBF offers the same functionality in tube packaging with commercial temperature ratings.
