LTC2636IMS-LZ10#TRPBF

Overview

The LTC2636IMS-LZ10#TRPBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc. It features an integrated high-accuracy reference with a temperature coefficient of 10ppm/°C, providing a full-scale output of 2.5V. The device operates on a single supply ranging from 2.7V to 5.5V and includes rail-to-rail output buffers that are guaranteed monotonic over the industrial temperature range of –40°C to 85°C. Communication is handled via a 3-wire SPI/MICROWIRE-compatible interface supporting clock rates up to 50MHz. This specific variant resets to zero-scale upon power-up.

Feature Summary

• Octal 10-bit DACs with integrated 10ppm/°C reference
• 2.5V full-scale output with 2.7V to 5.5V supply range
• Power-on reset to zero-scale for consistent initialization
• 16-lead MSOP package with hardware CLR and LDAC pins

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Automotive Systems

Procurement Notes

Verify the suffix #TRPBF indicates tape and reel packaging containing 2500 pieces. Confirm the IMS designation corresponds to the 16-lead MSOP package and LZ10 specifies the 10-bit resolution with zero-scale power-on reset behavior. Ensure the component meets the specified industrial temperature grade requirements for the target application environment.

Selection Notes

Select this part when eight independent 10-bit channels are required with low drift characteristics. The internal reference simplifies design by eliminating external precision components. Choose the LZ variant if system safety requires outputs to default to zero volts during power-up sequences. Verify that the 2.5V full-scale range aligns with downstream circuit input requirements.

Part Context

This component belongs to the LTC2636 family, which offers 12-, 10-, and 8-bit resolutions in both DFN and MSOP packages. The 'L' suffix denotes the 2.5V full-scale version operating from 2.7V to 5.5V supplies. The 'I' grade covers the industrial temperature range of –40°C to 85°C. The 'MS' package type provides additional control pins compared to the DFN option.

Replacement Considerations

Direct substitutes within the same family include LTC2636IMS-LZ12#TRPBF (12-bit) or LTC2636IMS-LZ8#TRPBF (8-bit). For different reset behaviors, consider LTC2636IMS-LMI10#TRPBF (mid-scale reset). External reference variants like LTC2636IMS-LMX10#TRPBF allow custom full-scale voltages but require external reference components.
