LTC2655BIUF-L16#TRPBF

Overview

The LTC2655BIUF-L16#TRPBF is a quad 16-bit digital-to-analog converter featuring an integrated 10ppm/°C maximum reference. It operates from a single 2.7V to 5.5V supply with a full-scale output of 2.5V. The device includes high-performance rail-to-rail output buffers and guarantees monotonicity over temperature. It utilizes a 2-wire I²C compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical specifications include a maximum integral nonlinearity error of ±4LSB, a settling time of 9.1µs for 16-bit accuracy, and a typical glitch impulse of 4nV•s at mid-scale transitions.

Feature Summary

• Quad 16-bit resolution with ±4LSB maximum INL error
• Integrated 10ppm/°C max reference providing 2.5V full-scale output
• Rail-to-rail output buffers guaranteed monotonic over temperature
• I²C interface with selectable power-on reset to zero-scale or mid-scale

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the 'B' grade designation corresponds to the required ±4LSB maximum INL specification for your application. Ensure the supplier provides documentation confirming the lead-free design status as specified in the manufacturer's ordering information.

Selection Notes

Select this part if a quad DAC configuration with 16-bit precision and low drift is required. The -L suffix indicates a 2.5V full-scale range suitable for 2.7V to 5.5V supplies. Consider the UF package (20-lead QFN) for compact designs. Verify that the I²C address pins (CA0-CA2) can be configured to avoid bus conflicts in multi-device systems.

Part Context

This component belongs to the LTC2655 family of quad I²C DACs. Variants exist with different resolutions (12-bit), accuracy grades (C-grade with ±1LSB INL), and full-scale voltages (-H option with 4.096V). The BIUF-L16 variant specifically combines industrial temperature range, B-grade accuracy, QFN packaging, and 16-bit resolution.

Replacement Considerations

Direct substitutes within the same family include LTC2655BCUF-L16#TRPBF for commercial temperature range applications. For higher accuracy requirements, consider the C-grade variants such as LTC2655CCUF-L16#TRPBF. Ensure any replacement maintains the same 20-lead QFN footprint and I²C interface compatibility.
