LTC2636CDE-HMI12#TRPBF

Overview

The LTC2636CDE-HMI12#TRPBF is an octal 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated 4.096V full-scale reference with a temperature coefficient of 10ppm/°C. 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 in internal reference mode, and rail-to-rail output buffers guaranteed monotonic over the commercial temperature range of 0°C to 70°C.

Feature Summary

• Octal 12-bit resolution with ±2.5LSB maximum integral nonlinearity error
• Integrated 4.096V full-scale reference with 10ppm/°C drift
• Rail-to-rail output buffers with ultralow DAC-to-DAC crosstalk (<2.4nV•s)
• Power-on reset to mid-scale in internal reference mode

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Automotive systems
• Optical networking

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 range for the 4.096V full-scale output configuration.

Selection Notes

Select this part for applications requiring eight independent 12-bit channels with high accuracy and low drift. The H-grade variant necessitates a minimum 4.5V supply, distinguishing it from the L-grade which supports 2.7V operation with a 2.5V full-scale output. The MI suffix ensures a predictable mid-scale initialization state upon power-up when using the internal reference.

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 the commercial range of 0°C to 70°C, while I and H grades extend to industrial and automotive ranges respectively. The DE package is a 14-lead plastic DFN measuring 4mm x 3mm.
