LTC2656BIFE-H16#PBF

Digital To Analog Converters Overview

The LTC2656BIFE-H16#PBF is an octal, 16-bit digital-to-analog converter (DAC) from Analog Devices. It features a precision integrated reference with a maximum temperature coefficient of 10ppm/°C and operates within a supply voltage range of 4.5V to 5.5V. The device provides a full-scale output of 4.096V when using the internal reference. Each channel includes high-performance, rail-to-rail output buffers that are guaranteed monotonic over temperature. Communication is handled via a 4-wire SPI/MICROWIRE compatible serial interface supporting clock rates up to 50MHz. The component is housed in a 20-lead thermally enhanced TSSOP package.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and lead finish. Confirm that the H16 designation corresponds to the required 4.096V full-scale output and 4.5V–5.5V supply range for your design. Ensure compatibility with the 20-lead thermally enhanced TSSOP footprint during PCB layout.

Digital To Analog Converters Selection Notes

Select this part if an octal configuration with 16-bit resolution is required. The H16 variant is appropriate for designs needing a 4.096V output span powered by a 4.5V to 5.5V supply. Consider the L16 variant if a 2.5V output span and lower 2.7V minimum supply voltage are sufficient for the application requirements.

Digital To Analog Converters Part Context

This component belongs to the LTC2656 family of octal DACs. Variants exist with different resolutions (12-bit or 16-bit), accuracy grades (±4LSB or ±12LSB INL), and full-scale voltages (2.5V or 4.096V). The BIFE-H16 specifically denotes the industrial/commercial grade, 16-bit resolution, 4.096V full-scale option in the TSSOP package.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other members of the LTC2656 family such as the LTC2656BCFE-H16#PBF for commercial temperature range or LTC2656BIUFD-H16#PBF for QFN packaging. Verify pinout compatibility and electrical specifications before substitution.
