LTC2635HMSE-HZ10#PBF

Overview

The LTC2635HMSE-HZ10#PBF is a quad 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc. It features an integrated precision reference with a full-scale output of 4.096V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 4.5V to 5.5V. It utilizes a 2-wire I²C-compatible serial interface supporting standard mode (100kHz) and fast mode (400kHz). Key specifications include rail-to-rail output buffers, guaranteed monotonicity over the –40°C to 125°C automotive temperature range, and a maximum integral nonlinearity error of ±1 LSB.

Feature Summary

• Quad 10-bit resolution with integrated 4.096V precision reference
• I²C-compatible serial interface with standard (100kHz) and fast (400kHz) modes
• Rail-to-rail output buffers and guaranteed monotonic operation
• Power-on reset options including zero-scale, mid-scale, or high-impedance states

Applications

• Mobile communications systems
• Process control and industrial automation
• Power supply margining
• Portable equipment
• Automotive applications

Procurement Notes

Verify that the ordering suffix #PBF confirms lead-free construction. Confirm the MSE package designation corresponds to the 10-lead MSOP form factor. Ensure the H grade matches the required automotive temperature range of –40°C to 125°C. Validate the Z power-on reset configuration against system startup requirements.

Selection Notes

Select this part for designs requiring four independent DAC channels in a compact surface-mount package. The 4.096V internal reference eliminates the need for external components if this voltage level is suitable. Verify that the 4.5V minimum supply voltage aligns with the system power rails. Consider the I²C address selection via CA0–CA2 pins if multiple devices are present on the bus.

Part Context

This component belongs to the LTC2635 family, which includes 8-bit, 10-bit, and 12-bit variants. The HMSE suffix indicates the H-grade automotive temperature rating and the MSE 10-lead MSOP package. The LZ10 suffix specifies the 10-bit resolution and the zero-scale power-on reset behavior. Other family members offer different resolutions or reset configurations.

Replacement Considerations
