LTC2655BIGN-L16#TRPBF

Overview

The LTC2655BIGN-L16#TRPBF is a quad 16-bit rail-to-rail digital-to-analog converter (DAC) from Analog Devices, housed in a 16-lead narrow SSOP package. It features an integrated reference with a maximum temperature coefficient of 10ppm/°C and guaranteed monotonicity over temperature. The device operates on a single supply voltage ranging from 2.7V to 5.5V, delivering a full-scale output of 2.5V when using the internal reference. Control is managed via a 2-wire I²C compatible serial interface supporting standard (100kHz) and fast (400kHz) modes.

Feature Summary

• Quad 16-bit resolution with ±4 LSB maximum INL error
• Integrated 10ppm/°C max reference providing 2.5V full-scale output
• Rail-to-rail output buffers with ultralow crosstalk (<1nV·s)
• I²C interface with configurable power-on reset to zero 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 confirms tape and reel packaging for automated assembly. Confirm the B grade designation indicates ±4LSB maximum INL performance. Ensure the GN package corresponds to the 16-lead narrow SSOP form factor required by the PCB footprint. Check that the L option specifies the 2.7V to 5.5V supply range and 2.5V full-scale output characteristic.

Selection Notes

Select this part for applications requiring four independent 16-bit voltage outputs with high precision and low drift. The integrated reference simplifies design by eliminating external components, provided the 2.5V full-scale span meets system requirements. Consider the I²C interface constraints and ensure the microcontroller supports the required clock speeds. Verify that the 16-lead SSOP package fits within the available board space constraints.

Part Context

This component belongs to the LTC2655 family of quad DACs, which also includes 12-bit variants and H-grade options with 4.096V full-scale output. The B grade offers tighter linearity specifications compared to the C grade. The GN package variant provides a compact solution for space-constrained designs compared to the QFN options available in the same series.

Replacement Considerations

Direct substitutes within the same family include LTC2655BCGN-L16#TRPBF for identical specifications in tube packaging. For higher accuracy requirements, consider the LTC2655BIUF-L16#TRPBF in QFN format. If 12-bit resolution is sufficient, the LTC2655CGN-L12#TRPBF offers lower cost alternatives with similar pinouts.
