LTC2755IUP-12#PBF

Digital To Analog Converters Overview

The LTC2755IUP-12#PBF is a quad, 12-bit multiplying digital-to-analog converter (DAC) with parallel input/output and current output. It operates from a single 2.7V to 5.5V supply and features SoftSpan technology for six programmable output ranges: two unipolar (0V to 5V, 0V to 10V) and four bipolar (±5V, ±10V, ±2.5V, –2.5V to 7.5V). The device guarantees monotonicity over temperature, offers a maximum supply current of 1μA, and includes a bidirectional parallel interface for register readback. It incorporates power-on reset and an asynchronous clear function.

Digital To Analog Converters Feature Summary

• Quad 12-bit resolution with guaranteed monotonicity over temperature
• SoftSpan architecture supporting six software-programmable or pin-strapped output ranges
• Bidirectional parallel I/O interface enabling readback of all internal registers
• Low power consumption with maximum 1μA supply current

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the ordering suffix 'I' indicates the industrial temperature range (-40°C to +85°C) and '#PBF' denotes lead-free finish. Confirm the package type is the 64-lead 9mm × 9mm plastic QFN. Ensure the specific revision matches the datasheet version required for design integration.

Digital To Analog Converters Selection Notes

Select this part when four independent 12-bit current-output channels are required with high DC accuracy and low power. The SoftSpan feature allows flexible voltage range configuration without external resistor networks. Compare against LTC2753 (dual channel) or LTC2751 (single channel) if fewer channels suffice.

Digital To Analog Converters Part Context

The LTC2755 belongs to Analog Devices' SoftSpan DAC family, which integrates precision reference amplifiers and switching architectures to enable multiple output spans from a single reference voltage. This family includes dual (LTC2753) and single (LTC2751) channel variants sharing similar electrical characteristics and interface protocols.

Digital To Analog Converters Replacement Considerations

For direct pin-compatible replacements within the same family, consider the LTC2755CUP-12#PBF for commercial temperature range (0°C to 70°C) or higher-resolution variants like the LTC2755IUP-16#PBF if 16-bit performance is needed.
