LTC1416IG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1416IG#PBF is a low-power, 14-bit successive approximation sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from dual ±5V supplies and dissipates 70mW at a maximum sampling rate of 400ksps. The device features a true differential input sample-and-hold with a full-scale range of –2.5V and a 15MHz full-power bandwidth. Key performance metrics include an 80.5dB signal-to-(noise + distortion) ratio at 100kHz input, 93dB total harmonic distortion, and guaranteed linearity of –1.5LSB DNL and –2LSB INL. It utilizes a parallel digital interface and includes internal shutdown modes.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence when sourcing. Confirm package integrity for the 28-lead SSOP form factor. Ensure supply voltages match the required ±5V rails for optimal DC accuracy specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range at moderate speeds. The 15MHz bandwidth supports undersampling techniques. Verify that the driving source impedance allows for the specified 400ns acquisition time to maintain full throughput rates without additional buffering.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1416 family of sampling ADCs. The IG suffix denotes the industrial temperature range variant (-40°C to 85°C), distinguishing it from commercial grade options. It serves as a complete solution integrating the SAR core, clock, and reference in a single package.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the LTC1416CG for commercial temperature ranges. Cross-family substitution requires verification of interface timing and power supply requirements.
