LTC2654BIGN-H16#TRPBF

Overview

The LTC2654BIGN-H16#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 4.096V. The device operates from a single 4.5V to 5.5V supply and includes high-performance output buffers guaranteed monotonic over temperature. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±4LSB, low offset error of ±2mV, and ultralow crosstalk between DACs (<3nV•s). 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 4.096V reference and ±4LSB max INL
• Rail-to-rail output buffers with <3nV•s DAC-to-DAC crosstalk
• SPI/MICROWIRE compatible 4-wire serial interface with 50MHz clock rate
• Power-on reset configurable to zero-scale or mid-scale via PORSEL pin

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 the ±4LSB maximum INL specification required for the application. Ensure the H16 suffix matches the 4.096V full-scale voltage requirement and that the system power supply range supports the 4.5V to 5.5V operating voltage specified for this variant.

Selection Notes

Select this component when a quad-channel 16-bit DAC with an integrated high-precision reference is required. The -H suffix designates the 4.096V full-scale output mode, necessitating a minimum supply voltage of 4.5V. The GN package identifies the 16-lead narrow SSOP form factor. For applications requiring lower supply voltages or different full-scale outputs, consider the -L variants which operate down to 2.7V with a 2.5V reference output.

Part Context

This part belongs to the LTC2654 family of quad DACs, which also offers 12-bit resolution options and alternative packages such as the 20-lead QFN. The B grade provides tighter linearity specifications compared to standard C grade parts. The H16 configuration specifically targets applications needing higher voltage swings with integrated reference accuracy, distinguishing it from external reference configurations or lower voltage -L series devices.
