LTC2636IDE-HMI12#TRPBF

Overview

The LTC2636IDE-HMI12#TRPBF is an octal 12-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 4.5V to 5.5V supply 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 mid-scale, and rail-to-rail output buffers guaranteed monotonic over the industrial temperature range of –40°C to 85°C.

Feature Summary

• Octal 12-Bit Resolution: Provides eight independent 12-bit DAC channels with maximum integral nonlinearity error of ±2.5LSB.
• Integrated Precision Reference: Features an internal 10ppm/°C reference setting a 4.096V full-scale output.
• Industrial Temperature Range: Operates reliably from –40°C to 85°C.
• Power-On Reset: Resets outputs to mid-scale upon power-up for consistent system initialization.

Applications

• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment

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 matches the required 4.5V to 5.5V supply voltage constraints for the 4.096V full-scale output configuration.

Selection Notes

Select this part when eight isolated 12-bit channels are required within a compact footprint. The H-grade variant is necessary for applications demanding a 4.096V output span, distinguishing it from the L-grade 2.5V variants. The MSOP package offers dedicated CLR and LDAC pins if hardware control is preferred over the combined CS/LD pin found in the DFN version.

Part Context

This component belongs to the LTC2636 family of octal DACs available in 12-, 10-, and 8-bit resolutions. The 'I' suffix denotes the industrial temperature grade, while 'H' specifies the 4.096V internal reference mode. The 'DE' package code identifies the 14-lead plastic DFN housing, which lacks the separate CLR and LDAC pins present in the 16-lead MSOP alternative.
