LTC2625CGN-1#TRPBF

Overview

The LTC2625CGN-1#TRPBF is an octal 12-bit rail-to-rail voltage-output digital-to-analog converter (DAC) in a 16-lead narrow 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 mode (100kHz) and fast mode (400kHz). As a -1 variant, it incorporates a power-on reset circuit that sets outputs to mid-scale upon initialization. Key electrical specifications include a settling time of 7µs, differential nonlinearity of ±0.5 LSB, integral nonlinearity of ±1 LSB, and a typical supply current of 2.5mA at 5V.

Feature Summary

• Octal 12-bit resolution with rail-to-rail voltage outputs and guaranteed monotonicity
• Power-on reset to mid-scale for the -1 suffix variant
• I²C interface with 27 selectable addresses via CA0-CA2 pins
• Individual channel power-down capability reducing current to 1µA max

Applications

• Mobile communications systems
• Process control and industrial automation
• Instrumentation and automatic test equipment

Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging rather than tube packaging. Confirm the -1 designation matches the required mid-scale power-on reset behavior instead of zero-scale. Ensure the CGN temperature range (0°C to 70°C) meets application environmental requirements.

Selection Notes

Select this component when eight independent 12-bit channels are required in a compact 16-lead SSOP footprint. Choose the -1 version if system initialization requires outputs to settle at mid-scale rather than zero-scale. Verify that the 400kHz I²C clock speed and 2.7V to 5.5V supply range align with the host controller and power architecture.

Part Context

This part belongs to the LTC2605/LTC2615/LTC2625 family of octal DACs. The LTC2625 provides 12-bit resolution, whereas the LTC2615 offers 14 bits and the LTC2605 provides 16 bits. All variants share identical pinouts, interfaces, and physical dimensions, allowing for pin-compatible upgrades or downgrades based on resolution needs.

Replacement Considerations

LTC2625CGN-1#PBF: Identical electrical performance but supplied in tube packaging instead of tape and reel.
