LTC2634IMSE-HZ10#TRPBF

Overview

The LTC2634IMSE-HZ10#TRPBF is a quad 10-bit voltage output DAC with an integrated precision reference. It features rail-to-rail output buffers and operates from a single 4.5V to 5.5V supply, providing a full-scale output of 4.096V in internal reference mode. The device guarantees monotonicity over the -40°C to 125°C temperature range. Key electrical parameters include a maximum Integral Nonlinearity (INL) error of ±2.5 LSB, a supply current of 0.7mA at 5V, and a settling time of 4.2µs for 10-bit resolution. It communicates via a 50MHz SPI/MICROWIRE compatible interface.

Feature Summary

• Quad 10-bit DACs with integrated 4.096V full-scale reference
• Rail-to-rail output buffers with guaranteed monotonicity
• AEC-Q100 qualified for automotive applications (-40°C to 125°C)
• Power-on reset to zero-scale in internal reference mode

Applications

• Automotive systems
• Process control and industrial automation
• Portable equipment

Procurement Notes

Verify the HZ10 suffix indicates 10-bit resolution, 4.096V full-scale, zero-scale power-on reset, and automotive grade. Confirm the MSE package corresponds to the 10-lead MSOP form factor. Ensure the TRPBF suffix denotes tape and reel packaging with lead-free composition as per Analog Devices specifications.

Selection Notes

Select this part when a quad DAC configuration is required with high accuracy and automotive qualification. The 4.5V minimum supply voltage distinguishes it from the 2.7V capable LTC2634-L variants. The zero-scale power-on reset is critical for safety-critical applications where undefined outputs during startup must be avoided.

Part Context

This component belongs to the LTC2634 family of quad DACs. The IMSE designation specifies the Industrial/Automotive temperature grade (I) and the 10-lead MSOP package (MSE). The HZ10 suffix defines the specific electrical characteristics: High voltage range (H), Zero-scale reset (Z), and 10-bit resolution (10).

Replacement Considerations

Direct substitutes within the same family include LTC2634IMSE-HZ12#TRPBF (12-bit) or LTC2634IMSE-HZ8#TRPBF (8-bit). For lower voltage operation, consider the LTC2634LMSE series, noting the different supply requirements.
