LTC2655BCGN-H16#TRPBF

Overview

The LTC2655BCGN-H16#TRPBF is a quad, 16-bit rail-to-rail digital-to-analog converter (DAC) from Analog Devices Inc. It features an integrated reference with a maximum temperature coefficient of 10ppm/°C and a full-scale output voltage of 4.096V. The device operates on a single supply voltage ranging from 4.5V to 5.5V and 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 ±4LSB at 16 bits, guaranteed monotonicity over the operating temperature range, and a settling time of 9.1µs for ±1LSB accuracy. The component is housed in a 16-lead narrow SSOP package.

Feature Summary

• Quad 16-bit resolution with ±4LSB maximum INL error
• Integrated 4.096V full-scale reference with 10ppm/°C max temperature coefficient
• Rail-to-rail output buffers with ultralow crosstalk (<1nV•s)
• Selectable power-on reset 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 specific ordering suffix #TRPBF confirms tape and reel packaging when sourcing this component. Ensure the supplier documentation matches the Analog Devices Inc. manufacturer identification for the LTC2655BCGN-H16 part number. Confirm that the commercial temperature grade (0°C to 70°C) aligns with the system requirements before procurement.

Selection Notes

Select the -H suffix variant if a 4.096V full-scale output is required, noting the minimum supply voltage requirement of 4.5V. Choose the -GN package for 16-lead narrow SSOP form factors. The -B electrical grade provides ±4LSB INL, which is suitable for general precision applications; consider other grades if tighter linearity is needed.

Part Context

This component belongs to the LTC2655 family of quad DACs, which also includes 12-bit variants and QFN package options. The -L suffix denotes a 2.5V full-scale output with a lower minimum supply voltage of 2.7V, whereas the -H suffix used here specifies the 4.096V output configuration. The BC designation indicates the commercial temperature grade and the specific INL performance level.

Replacement Considerations

Direct substitutes within the same family include LTC2655BCGN-L16#TRPBF for 12-bit resolution or LTC2655BIUF-H16#TRPBF for industrial temperature range and QFN packaging. Verify pin compatibility and software register mapping when switching between different resolution or package variants.
