LTC2751CUHF-12#TRPBF

Digital To Analog Converters Overview

The LTC2751CUHF-12#TRPBF is a 12-bit multiplying digital-to-analog converter with parallel input and current output. It operates from a single 2.7V to 5.5V supply and guarantees monotonicity over the commercial temperature range of 0°C to 70°C. The device features SoftSpan technology, allowing six programmable output ranges (two unipolar, four bipolar) via software or hardware pin strapping. Key electrical specifications include a maximum settling time of 2µs to ±1 LSB, a glitch impulse of 1nV·s, and a typical supply current of 0.5µA. It utilizes a bidirectional parallel interface supporting readback of all internal registers.

Digital To Analog Converters Feature Summary

• 12-bit resolution with guaranteed monotonicity over temperature
• SoftSpan architecture offering six programmable output ranges
• Bidirectional parallel I/O interface with full register readback capability
• Low power consumption with 0.5µA typical supply current

Digital To Analog Converters Applications

• High-resolution offset and gain adjustment circuits
• Process control and industrial automation systems
• Automatic test equipment requiring precise voltage generation
• Data acquisition systems needing accurate signal conditioning

Digital To Analog Converters Procurement Notes

Verify that the component matches the specific package type and temperature grade required for the design. Confirm that the ordering suffix corresponds to the tape and reel packaging format intended for automated assembly processes. Ensure compatibility with the system's logic voltage levels and reference requirements before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this model when a 12-bit resolution is sufficient for the application's accuracy requirements. The commercial temperature range (0°C to 70°C) suits standard indoor environments. Consider the bidirectional parallel interface if the host microcontroller supports wide data buses and requires register verification capabilities during operation.

Digital To Analog Converters Part Context

This part belongs to the LTC2751 family of SoftSpan DACs, which includes 14-bit and 16-bit variants. The 'C' suffix denotes the commercial temperature range, while 'UHF' indicates the 38-lead QFN package. The '#TRPBF' suffix specifies the tape and reel packaging option without lead-based finishes, distinguishing it from tube-packaged equivalents.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include the LTC2751IUHF-12#TRPBF for industrial temperature range applications. Higher resolution options such as the LTC2751BIUHF-16#TRPBF are compatible in terms of interface and pinout but offer increased precision.
