LTC2636CDE-HMI8#TRPBF

Overview

The LTC2636CDE-HMI8#TRPBF is an octal, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a 14-lead DFN package and operates within a supply voltage range of 4.5V to 5.5V. The device includes an integrated internal reference providing a full-scale output of 4.096V, with a power-on reset configured to set outputs to mid-scale in internal reference mode. It utilizes a 3-wire SPI/MICROWIRE-compatible serial interface for communication.

Feature Summary

• Octal architecture with 8 independent 8-bit DAC channels
• Integrated 4.096V full-scale internal reference
• Power-on reset to mid-scale in internal reference mode
• Rail-to-rail output buffers guaranteed monotonic over temperature

Applications

• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Automotive systems

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 H-grade specification aligns with the required 4.5V to 5.5V supply voltage constraints for the application.

Selection Notes

Select this part when eight low-cost, 8-bit DAC channels are required with a fixed 4.096V output span. The H-grade variant necessitates a minimum supply voltage of 4.5V. Choose the MI suffix if a mid-scale initialization state is preferred upon power-up rather than zero-scale.

Part Context

This component belongs to the LTC2636 family of octal DACs available in 12-, 10-, and 8-bit resolutions. The C temperature grade covers commercial applications from 0°C to 70°C. The H designation specifies the higher voltage operation range compared to the L-series parts.

Replacement Considerations

LTC2636CDE-HZ12#TRPBF: Offers identical pinout and electrical characteristics but resets to zero-scale instead of mid-scale upon power-up.
