LTC2636CDE-HMI10#TRPBF

Overview

The LTC2636CDE-HMI10#TRPBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 4.096V and operates on a single 4.5V to 5.5V supply. The device utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. It includes double-buffered data latches, rail-to-rail output buffers, and guaranteed monotonicity over the commercial temperature range of 0°C to 70°C. Power-on reset defaults to mid-scale in internal reference mode.

Feature Summary

• Octal 10-bit resolution with integrated 4.096V precision reference
• Rail-to-rail output buffers with guaranteed monotonicity
• 3-wire SPI/MICROWIRE serial interface operating up to 50MHz
• Power-on reset to mid-scale in internal reference mode

Applications

• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Mobile communications

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging containing 2500 pieces. Confirm the DE package designation corresponds to the 14-lead DFN form factor. Ensure the HMI10 code matches the required 4.096V full-scale output and mid-scale power-on reset behavior for the target application design.

Selection Notes

Select this part when eight independent 10-bit DAC channels are required with a 4.096V span. The H-grade internal reference necessitates a supply voltage between 4.5V and 5.5V. Choose the C temperature grade for commercial environments limited to 0°C to 70°C. Verify that the MSOP package is not required, as this DFN variant lacks dedicated CLR and LDAC pins.

Part Context

This component belongs to the LTC2636 family of octal DACs available in 8-, 10-, and 12-bit resolutions. The 'H' suffix denotes the 4.096V full-scale version requiring higher supply voltages compared to the 'L' variant. The 'DE' package identifies the 14-lead plastic DFN footprint, distinguishing it from the 16-lead MSOP option which provides additional control pins.

Replacement Considerations

Public confirmed substitute part numbers: LTC2636CDE-HZ10#TRPBF, LTC2636CDE-HMX10#TRPBF.
