LTC2655CUF-L12#TRPBF

Overview

The LTC2655CUF-L12#TRPBF is a quad 12-bit rail-to-rail digital-to-analog converter (DAC) from Analog Devices, housed in a 20-lead 4mm × 4mm QFN package. It features an integrated 1.25V reference, yielding a full-scale output of 2.5V. The device operates on a single supply voltage ranging from 2.7V to 5.5V and utilizes a 2-wire I²C compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical specifications include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 3.9µs for 12-bit accuracy, and a typical supply current of 1.7mA with the internal reference enabled.

Feature Summary

Quad channel architecture with built-in high-performance rail-to-rail output buffers
Integrated 1.25V reference providing a 2.5V full-scale output range
Guaranteed monotonic operation over temperature with ±1 LSB maximum INL
Ultralow crosstalk between DAC channels (<1nV•s)

Applications

Mobile communications systems
Process control and industrial automation
Instrumentation equipment
Automatic test equipment
Automotive applications

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the C grade corresponds to the commercial temperature range of 0°C to 70°C. Ensure the L suffix is selected for the 2.7V to 5.5V supply range and 2.5V full-scale output configuration.

Selection Notes

Select the LTC2655CUF-L12#TRPBF when four independent 12-bit voltage outputs are required with minimal inter-channel interference. This part is suitable for designs requiring a 2.5V span without external reference components. Consider the UF package dimensions if board space is constrained, and verify I²C bus speed requirements against the 400kHz fast mode capability.

Part Context

This component belongs to the LTC2655 family of quad DACs, which also offers 16-bit resolution variants and H-grade options with a 4.096V full-scale output. The CU designation identifies the commercial temperature grade, while the UF suffix specifies the 20-lead QFN package format used in this specific part number.
