LTC2758BCLX

Digital To Analog Converters Overview

The LTC2758BCLX is a dual-channel, 18-bit current-output digital-to-analog converter (DAC) from Analog Devices. It features SoftSpan technology, allowing the output range to be adjusted via software control of gain and offset parameters. The device operates on a single 5V supply and communicates through a high-speed SPI-compatible serial interface. Key electrical specifications include a settling time of 3 microseconds for full-scale transitions and a power dissipation of 40 milliwatts. The component is housed in a compact 16-lead LQFP package and supports an operating temperature range from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Dual-channel 18-bit resolution with integrated SoftSpan gain and offset trimming capabilities
• High-speed serial interface supporting clock rates up to 60 MHz
• Low power consumption with 40 mW typical power dissipation at 5V
• Monotonic operation guaranteed over the specified temperature range

Digital To Analog Converters Applications

• Programmable logic controller (PLC) analog output modules
• Industrial process control systems requiring precise current regulation
• Test and measurement equipment demanding high-resolution signal generation

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BCLX' against the official datasheet to confirm the industrial temperature grade (-40°C to +85°C) and tape-and-reel packaging configuration. Ensure compatibility with the required SPI mode and voltage levels before procurement.

Digital To Analog Converters Selection Notes

Select this component when dual-channel precision is required in a space-constrained design. The SoftSpan feature eliminates external trimming components, reducing bill-of-materials cost. Verify that the 3-microsecond settling time meets the system's update rate requirements.

Digital To Analog Converters Part Context

This part belongs to the LTC2758 family of high-performance DACs. It shares architectural similarities with the LTC2755 and LTC2754 but offers higher 18-bit resolution compared to the 12/14/16-bit variants in other series members.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same package may include other LTC2758 variants with different temperature grades or packaging options. Cross-family substitution requires verification of pinout and register compatibility.
