LTC2636IMS-HZ10#TRPBF

Overview

The LTC2636IMS-HZ10#TRPBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated high-accuracy reference with a temperature coefficient of 10ppm/°C, providing a full-scale output of 4.096V. The device operates on a single supply voltage ranging from 4.5V to 5.5V and utilizes a 3-wire SPI/MICROWIRE-compatible serial interface with clock rates up to 50MHz. It includes double-buffered data latches, power-on reset to zero-scale in internal reference mode, and rail-to-rail output buffers. The component is housed in a 16-lead MSOP package and is guaranteed monotonic over the industrial temperature range of –40°C to 85°C.

Feature Summary

• Octal 10-bit resolution with integrated 4.096V full-scale reference
• Industrial temperature grade (-40°C to 85°C) in 16-lead MSOP package
• Power-on reset to zero-scale for consistent system initialization
• SPI/MICROWIRE compatible 3-wire serial interface operating at 50MHz

Applications

• Process control and industrial automation systems
• Portable equipment requiring low power consumption
• Automotive applications
• Optical networking infrastructure

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging containing 2500 pieces. Confirm the IMS designation corresponds to the industrial temperature range and MSOP package type. Ensure compatibility with the required 4.5V to 5.5V supply voltage for the H-grade variant.

Selection Notes

Select this part when eight independent 10-bit DAC channels are required with a fixed 4.096V output span. The H-series designation mandates a minimum supply voltage of 4.5V, distinguishing it from the L-series which supports 2.7V operation. The Z-suffix ensures outputs initialize to zero upon power-up, suitable for safety-critical or sensitive downstream circuits.

Part Context

This component belongs to the LTC2636 family of octal DACs, which also includes 12-bit and 8-bit variants. The family shares common architectural features such as the 10ppm/°C reference technology and SPI interface but differs in resolution, full-scale voltage options (2.5V vs 4.096V), and temperature grades (C, I, H).

Replacement Considerations

Direct pin-compatible replacements within the same package and temperature grade include other LTC2636 variants with different resolutions (LTC2636IMS-HZ12#TRPBF for 12-bit or LTC2636IMS-HZ8#TRPBF for 8-bit). Cross-family replacements like the LTC2637 offer I2C interfaces instead of SPI.
