LTC2753BIUK-16#TRPBF

Overview

The LTC2753BIUK-16#TRPBF is a dual-channel, 16-bit multiplying digital-to-analog converter (DAC) from Analog Devices Inc. It features SoftSpan technology, allowing six programmable output ranges: two unipolar (0V to 5V, 0V to 10V) and four bipolar (±2.5V, ±5V, ±10V, –2.5V to 7.5V). The device operates on a single 2.7V to 5.5V supply with a maximum supply current of 1μA. Key electrical specifications include a settling time of 2μs to ±1 LSB, a glitch impulse of 1nV•s, and guaranteed monotonicity over temperature. It utilizes a bidirectional parallel interface for data input and register readback.

Feature Summary

• Dual 16-bit current-output DAC with SoftSpan technology for software-selectable output ranges
• Six output ranges available: 0V to 5V, 0V to 10V, ±2.5V, ±5V, ±10V, and –2.5V to 7.5V
• Bidirectional parallel I/O interface supporting readback of all internal registers
• Low power consumption with 1μA maximum supply current and 2μs settling time

Applications

• Process control and industrial automation systems
• Automatic test equipment
• Data acquisition systems

Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging. Confirm the 'I' grade designation corresponds to the specified industrial operating temperature range of –40°C to +85°C. Ensure the component matches the 48-lead QFN package dimensions and exposed pad grounding requirements.

Selection Notes

Select this part for applications requiring high DC precision and low power in a compact form factor. The 16-bit resolution and ±1LSB INL make it suitable for demanding measurement tasks. Consider the bidirectional interface if system design requires reading back DAC codes. Verify that the external reference voltage aligns with the desired SoftSpan output scaling.

Part Context

This component belongs to the LTC2753 family of dual SoftSpan DACs. Variants within the family differ by resolution (12-, 14-, or 16-bit) and accuracy grade (C, B, A). The BIUK-16 variant specifically denotes the industrial temperature grade with 16-bit performance. Other members like the LTC2754 and LTC2755 offer similar functionality but with serial interfaces or quad channel configurations.

Replacement Considerations

Direct replacements within the same package and pinout include other LTC2753 variants such as LTC2753AIUK-16#TRPBF (higher accuracy) or LTC2753BCUK-16#TRPBF (commercial grade). For different channel counts or interfaces, consider the LTC2754 (serial) or LTC2755 (quad channel).
