LTC2619IGN-1#TRPBF

Overview

The LTC2619IGN-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 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, remaining there until a valid write and update occur.

Feature Summary

• Quad 14-bit resolution with guaranteed monotonicity over temperature
• I²C interface with 27 selectable addresses via CA0/CA1/CA2 pins
• Power-on reset to mid-scale for the -1 suffix variant
• Low power operation: 250µA per DAC at 3V; individual channel power down to 1µA

Applications

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

Procurement Notes

Verify the specific ordering suffix '#TRPBF' indicates tape and reel packaging and lead-free finish. Confirm the '-1' suffix corresponds to the mid-scale power-on reset behavior as documented in the manufacturer's ordering information table. Ensure compatibility with the 16-lead narrow SSOP physical footprint.

Selection Notes

Select this model for applications requiring four independent 14-bit channels with I²C connectivity. Choose the IGN grade for industrial temperature ranges (-40°C to 85°C). Consider the -1 suffix if mid-scale power-on reset is required instead of zero-scale. Verify supply voltage constraints between 2.7V and 5.5V match system requirements.

Part Context

This component belongs to the LTC2609/LTC2619/LTC2629 family of quad DACs. The LTC2619 specifically offers 14-bit resolution, distinguishing it from the 16-bit LTC2609 and 12-bit LTC2629. All variants share pin compatibility and the same 16-lead SSOP package form factor.

Replacement Considerations

LTC2609IGN-1#TRPBF (16-bit version), LTC2629IGN-1#TRPBF (12-bit version). These parts are pin-compatible but differ in resolution.
