LTC2656CUFD-H12#PBF

Overview

The LTC2656CUFD-H12#PBF is an octal 12-bit rail-to-rail digital-to-analog converter (DAC) family member from Analog Devices. It features a precision integrated reference with a maximum temperature coefficient of 10ppm/°C, providing a full-scale output voltage of 4.096V. The device operates on a single supply voltage ranging from 4.5V to 5.5V and includes built-in high-performance output buffers guaranteed to be monotonic over the operating temperature range. 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 4mm × 5mm plastic QFN package.

Feature Summary

Octal architecture with eight independent 12-bit DAC channels
Integrated precision reference yielding 4.096V full-scale output
Ultralow crosstalk between DACs (<1nV•s)
Power-on reset configurable to zero-scale or mid-scale

Applications

Mobile Communications
Process Control and Industrial Automation
Instrumentation
Automatic Test Equipment
Automotive

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and lead finish. Confirm that the H-grade designation matches the required 4.5V to 5.5V supply range for your application design. Ensure compatibility with the 20-lead QFN footprint during PCB layout.

Selection Notes

Select this part when eight isolated analog outputs are required within a compact form factor. The H-grade variant is necessary if the system requires a 4.096V full-scale range; otherwise, the L-grade provides a 2.5V range for lower voltage supplies. Verify that the 12-bit resolution meets the system accuracy requirements compared to the available 16-bit options.

Part Context

This component belongs to the LTC2656 family of octal DACs. Variants exist with different resolutions (12-bit vs 16-bit), internal reference voltages (L-grade for 2.5V, H-grade for 4.096V), and packages (QFN vs TSSOP). The CUFD suffix specifically denotes the Commercial temperature grade (0°C to 70°C) and the 20-lead QFN package.

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2656IUFD-H12#PBF for industrial temperature range (-40°C to 85°C) or LTC2656CUFD-L12#PBF for 2.5V full-scale operation.
