LTC2626IDD-1#TRPBF

Overview

The LTC2626IDD-1#TRPBF is a single-channel, 12-bit rail-to-rail voltage output digital-to-analog converter (DAC) manufactured by Analog Devices. It operates on a supply voltage range of 2.7V to 5.5V and features a built-in high-performance output buffer guaranteed monotonic over temperature. The device utilizes a 2-wire I2C compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical specifications include a typical settling time of 6.8µs, a maximum differential nonlinearity (DNL) of ±0.5 LSB, and an integral nonlinearity (INL) of ±1 LSB. It incorporates a power-on reset circuit that defaults the output to mid-scale upon initialization.

Feature Summary

• Asynchronous DAC Update via LDAC Pin
• Power-On Reset to Mid-Scale

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Instrumentation
• Automatic Test Equipment

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the 'IDD' designation corresponds to the industrial temperature range of –40°C to +85°C. Ensure the ordering information matches the exact part number to guarantee correct package type and performance specifications.

Selection Notes

Select the LTC2626IDD-1#TRPBF for applications requiring a single-channel 12-bit DAC with I2C connectivity. The '-1' variant ensures outputs default to mid-scale during power-up, which is critical for systems sensitive to zero-scale glitches. Verify that the host microcontroller supports the required I2C clock speeds and address configuration via CA0, CA1, and CA2 pins.

Part Context

This component belongs to the LTC2606/LTC2616/LTC2626 family of rail-to-rail DACs. The LTC2626 specifically offers 12-bit resolution, distinguishing it from the 14-bit LTC2616 and 16-bit LTC2606. All members share identical pinouts and interfaces, allowing for design flexibility based on resolution requirements while maintaining board density benchmarks.

Replacement Considerations

Direct replacements within the same family include the LTC2626CDD-1#TRPBF for commercial temperature ranges or the LTC2616IDD-1#TRPBF and LTC2606IDD-1#TRPBF for higher resolution needs. These parts are pin-compatible and share the same interface protocols.
