LTC1279CSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1279CSW#TRPBF is a 12-bit, 600ksps sampling analog-to-digital converter (ADC) housed in a 24-lead plastic SO Wide package. It operates from a single 5V or ±5V supply and draws 60mW typically during conversion. The device features an internal synchronized clock, a precision reference, and a flexible parallel interface for DSPs. Key electrical parameters include a maximum sampling rate of 600kHz, 12-bit resolution with no missing codes, ±1LSB INL/DNL, and a typical S/(N+D) of 70dB at 100kHz input frequency.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the commercial grade temperature range meets operational requirements. Ensure the ordering documentation matches the exact manufacturer part number to avoid compatibility issues with existing designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring moderate speed and high accuracy without external clocking complexity. Consider the parallel interface constraints when designing PCB layouts. Evaluate power dissipation limits if operating near maximum sampling rates in enclosed environments.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1279 family of 12-bit ADCs. It shares architectural similarities with the LTC1274 and LTC1277 but offers higher throughput speeds. The device represents a transition point in Analog Devices' portfolio between older parallel ADCs and newer serial interfaces.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes include the LTC1274CSW#TRPBF and LTC1277ISW#TRPBF. Verify pin compatibility and interface timing differences before substitution. Check datasheet specifications for any changes in power consumption or linearity performance.
