LTC1416IG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1416IG#TRPBF is a low-power, 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates at a sampling rate of 400ksps with a power dissipation of 70mW from ±5V supplies. The device features a differential input sample-and-hold circuit with a full-scale input range of –2.5V and an internal 2.5V reference. Key performance metrics include 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 offers Nap and Sleep shutdown modes for power management.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the IG variant meets the required commercial operating temperature range of 0°C to 70°C. Ensure compatibility with the 28-lead SSOP package dimensions for PCB layout. Check for RoHS compliance status as specified in the manufacturer's documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range and low power consumption in a 14-bit SAR architecture. The internal reference simplifies design by eliminating external voltage references. Consider the 15MHz full-power bandwidth if undersampling techniques are employed. Verify that the parallel interface timing requirements align with the host microprocessor or DSP capabilities.

Analog To Digital Converters (ADC) Part Context

The LTC1416 belongs to the LTC1416 series of low-power sampling ADCs. It shares architectural similarities with other devices in the family but is distinguished by its specific 400ksps throughput and 70mW power profile. The IG#TRPBF designation identifies the industrial/commercial grade version in tape and reel packaging.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same product family include the LTC1418 and LTC1419, which offer different sampling rates and interface types. Verify pinout compatibility and electrical specifications before substitution.
