LTC2636IDE-HMI10#TRPBF

Overview

The LTC2636IDE-HMI10#TRPBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated 10ppm/°C reference with a full-scale output of 4.096V, requiring a supply voltage between 4.5V and 5.5V. The device includes rail-to-rail output buffers and guarantees monotonicity 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 mid-scale upon power-up in internal reference mode and is housed in a 14-lead DFN package.

Feature Summary

• Octal 10-bit resolution with ±1 LSB maximum integral nonlinearity error
• Integrated 10ppm/°C reference providing 4.096V full-scale output
• Rail-to-rail output buffers guaranteed monotonic over –40°C to 85°C
• 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 part number 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 for 4.5V to 5.5V operation aligns with system power requirements. Check RoHS compliance documentation for lead-free manufacturing standards.

Selection Notes

Select this component when eight independent 10-bit channels are required with high accuracy. The H-grade version is necessary for applications demanding a 4.096V full-scale range. Verify that the operating environment falls within the –40°C to 85°C industrial temperature limits. Consider the MSOP package if hardware LDAC and CLR pins are preferred over the DFN configuration.

Part Context

This part 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 capability. The 'DE' indicates the 14-lead DFN package, and 'HMI' defines the mid-scale power-on reset behavior in internal reference mode.
