LTC2619CGN-1#TRPBF

Overview

The LTC2619CGN-1#TRPBF is a quad 14-bit rail-to-rail voltage output digital-to-analog converter (DAC) in a 16-lead SSOP package. It features built-in high-performance output buffers and operates on a single supply voltage from 2.7V to 5.5V. The device uses a 2-wire I²C compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. It incorporates a power-on reset circuit that sets outputs to mid-scale upon initialization. Key specifications include guaranteed monotonicity, ±0.5 LSB DNL, and individual channel power-down capability.

Feature Summary

• Quad 14-bit resolution with rail-to-rail voltage outputs
• I²C interface with 27 selectable addresses and global address support
• Power-on reset to mid-scale for the -1 suffix variant
• Individual channel power-down reducing current to 1µA max

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment and instrumentation

Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging with lead-free finish. Confirm the -1 suffix requirement for mid-scale power-on reset behavior. Check RoHS compliance status as specified in the manufacturer documentation. Ensure the SSOP-16 package matches the target PCB footprint constraints.

Selection Notes

Select this model over the LTC2609 or LTC2629 based on the required 14-bit resolution balance between precision and data throughput. Choose the -1 suffix if mid-scale power-on reset is necessary; otherwise, use the non-suffixed version for zero-scale reset. Verify that the 400kHz I²C speed meets system bus requirements and that the 16-lead SSOP package fits the available board space.

Part Context

This component belongs to the LTC2609/LTC2619/LTC2629 family of pin-compatible quad DACs. The LTC2619 specifically offers 14-bit resolution, positioned between the 16-bit LTC2609 and the 12-bit LTC2629. All variants share the same 16-lead SSOP package and I²C interface architecture, allowing for design flexibility across different resolution needs within the same form factor.
