LTC2654BIGN-L16#TRPBF

Overview

The LTC2654BIGN-L16#TRPBF is a quad 16-bit rail-to-rail digital-to-analog converter (DAC) in a 16-lead narrow SSOP package. It features an integrated precision reference with a maximum temperature coefficient of 10ppm/°C, providing a full-scale output of 2.5V. The device operates from a single 2.7V to 5.5V supply and includes built-in high-performance output buffers guaranteed monotonic over temperature. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±4LSB at 16 bits, a low offset error of ±2mV maximum, and a settling time of 8.9µs for 16-bit accuracy. Communication is handled via a 4-wire SPI/Microwire compatible serial interface supporting clock rates up to 50MHz.

Feature Summary

• Quad 16-bit resolution with integrated 10ppm/°C max precision reference
• Rail-to-rail voltage outputs with built-in buffers
• Maximum INL error of ±4LSB and offset error of ±2mV
• SPI/Microwire compatible 4-wire serial interface with 50MHz clock rate

Applications

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

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging rather than tube packaging. Confirm the B grade corresponds to the ±4LSB maximum INL specification. Ensure the L suffix matches the required 2.5V full-scale output range for the specific application design.

Selection Notes

Select this part for applications requiring four independent 16-bit channels with high precision. The -L option is suitable for single-supply operation between 2.7V and 5.5V. Consider the external reference mode if a different full-scale voltage is needed, as the output span becomes twice the external reference voltage.

Part Context

This component belongs to the LTC2654 family, which also offers 12-bit resolution options and H-grade variants with a 4.096V full-scale output. The BIGN package variant provides a 16-lead narrow SSOP form factor, while other packages like QFN are available for different board space constraints.

Replacement Considerations

Direct substitutes within the same family include LTC2654BCGN-L16#TRPBF for commercial temperature range or LTC2654BIUF-L16#TRPBF for QFN packaging. Verify pin compatibility and thermal characteristics when switching between SSOP and QFN packages.
