LTC2636IMS-HMI10#PBF

Overview

The LTC2636IMS-HMI10#PBF 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 includes rail-to-rail output buffers, guaranteed monotonicity over the –40°C to 85°C temperature range, and communicates via a 3-wire SPI/MICROWIRE interface with clock rates up to 50MHz. It incorporates hardware clear (CLR) and asynchronous DAC update (LDAC) pins, double-buffered data latches, and a power-on reset circuit that defaults outputs to mid-scale.

Feature Summary

• Octal 10-bit resolution with integrated 4.096V precision reference
• Rail-to-rail output buffers with guaranteed monotonicity
• 3-wire SPI/MICROWIRE compatible serial interface operating up to 50MHz
• Hardware clear (CLR) and asynchronous DAC update (LDAC) capabilities

Applications

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

Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the IMS designation corresponds to the 16-lead MSOP package type. Ensure the HMI10 configuration matches the required 4.096V full-scale output and mid-scale power-on reset behavior for the target application environment.

Selection Notes

Select this part when eight independent 10-bit channels are required within a compact footprint. The H-grade variant supports the necessary 4.5V to 5.5V supply range for 4.096V outputs. Consider the MSOP package if exposed pad soldering is not feasible or if LDAC/CLR pin accessibility is required for system synchronization.

Part Context

This component belongs to the LTC2636 family, which offers octal DACs in 12-, 10-, and 8-bit resolutions. Variants include the LTC2636-L for 2.7V–5.5V operation with 2.5V full-scale and the LTC2636-H for 4.5V–5.5V operation with 4.096V full-scale. Package options include 14-lead DFN and 16-lead MSOP, with temperature grades ranging from commercial to automotive.
