LTC2654BCGN-H16#TRPBF

Overview

The LTC2654BCGN-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 4.096V reference with a maximum temperature coefficient of 10ppm/°C, requiring a supply voltage between 4.5V and 5.5V. The device offers ±4LSB maximum integral nonlinearity (INL), ±2mV offset error, and guaranteed monotonicity over temperature. Communication occurs via a 4-wire SPI/Microwire compatible interface supporting clock rates up to 50MHz. Key features include selectable power-on reset states, asynchronous update capabilities, and ultralow crosstalk.

Feature Summary

• Quad 16-bit resolution with ±4LSB max INL and ±2mV max offset error
• Integrated 4.096V reference with 10ppm/°C max temperature coefficient
• 4-wire SPI/Microwire serial interface with 50MHz clock rate
• Power-on reset configurable to zero-scale or mid-scale via PORSEL pin

Applications

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

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging rather than tube packaging. Confirm the BC prefix corresponds to the commercial temperature range (0°C to 70°C) and B grade accuracy. Ensure the H suffix matches the required 4.096V full-scale output specification for the target design.

Selection Notes

Select this part when a quad DAC configuration is required with high precision and low noise. The -H variant necessitates a minimum supply voltage of 4.5V, unlike the -L variant which operates down to 2.7V. Verify that the 16-lead SSOP package fits the PCB layout constraints compared to the 20-lead QFN option.

Part Context

This component belongs to the LTC2654 family of precision DACs. The specific suffixes define key attributes: 'B' denotes the electrical grade with ±4LSB INL, 'C' indicates the commercial temperature range, 'GN' specifies the 16-lead narrow SSOP package, 'H' sets the internal reference to 4.096V, and '16' confirms 16-bit resolution.
