LTC2655BCGN-L16#TRPBF

Overview

The LTC2655BCGN-L16#TRPBF is a quad, 16-bit digital-to-analog converter (DAC) from Analog Devices Inc., housed in a 16-lead narrow SSOP package. It features an integrated reference providing a full-scale output of 2.5V and operates on a single 2.7V to 5.5V supply. The device utilizes a 2-wire I²C compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±4 LSB, a settling time of 9.1µs for 16-bit accuracy, and guaranteed monotonicity over the commercial temperature range of 0°C to 70°C.

Feature Summary

• Quad 16-bit resolution with rail-to-rail output buffers
• Integrated 10ppm/°C max temperature coefficient reference
• Maximum INL error of ±4 LSB
• I²C interface with selectable 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 when sourcing components. Confirm that the B grade designation corresponds to the required ±4 LSB maximum INL specification for the application. Ensure the commercial temperature range (0°C to 70°C) aligns with the operational environment requirements before procurement.

Selection Notes

Select this part for applications requiring four independent voltage outputs with high linearity and low crosstalk. The -L option provides a 2.5V full-scale output suitable for lower voltage systems, while the -H option offers 4.096V. Choose the GN package for space-constrained designs where a 16-lead narrow SSOP is preferred over the 20-lead QFN alternative.

Part Context

This component belongs to the LTC2655 family of quad DACs, which also includes 12-bit variants and different package options such as the 20-lead QFN. The BC prefix indicates a commercial temperature grade with enhanced linearity compared to the standard C grade. The L suffix denotes the internal reference voltage setting of 2.5V.

Replacement Considerations

Direct substitutes within the same family include the LTC2655CGN-L16#TRPBF, which shares the same package and interface but has a higher maximum INL error of ±1 LSB. For industrial temperature ranges, the LTC2655BIGN-L16#TRPBF is available in the same package.
