LTC2629CGN#TRPBF

Overview

The LTC2629CGN#TRPBF is a quad 12-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 of 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 holds outputs at zero-scale until a valid write and update occur. Key specifications include ±0.5 LSB DNL, ±1 LSB INL, and individual channel power-down capability.

Feature Summary

• Quad 12-bit resolution with rail-to-rail voltage outputs
• I²C interface with 27 selectable addresses via CA0/CA1/CA2 pins
• Power-on reset to zero-scale for consistent initialization
• Individual channel power-down reduces current to 1µA max

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging and lead-free finish. Confirm the 'GN' designation corresponds to the commercial temperature range (0°C to 70°C). Check manufacturer documentation for current lifecycle status as components may reach end-of-life.

Selection Notes

Select this model for applications requiring four independent 12-bit DAC channels in a compact 16-lead SSOP footprint. Ensure the system requires I²C communication and benefits from rail-to-rail output swing. Verify that the 0°C to 70°C operating range meets environmental requirements; use the 'IGN' variant for extended -40°C to 85°C operation.

Part Context

This component belongs to the LTC2609/LTC2619/LTC2629 family of pin-compatible quad DACs. The LTC2629 specifically offers 12-bit resolution, whereas the LTC2609 provides 16 bits and the LTC2619 provides 14 bits. All variants share the same package, interface, and general electrical characteristics.

Replacement Considerations

For extended temperature ranges, consider the LTC2629IGN#TRPBF (-40°C to 85°C). For higher resolution, the LTC2619IGN#TRPBF (14-bit) or LTC2609IGN#TRPBF (16-bit) are pin-compatible alternatives.
