LTC2634HUD-LZ10#TRPBF

Overview

The LTC2634HUD-LZ10#TRPBF is a quad 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 125°C automotive temperature range, and communicates via a 50MHz SPI/MICROWIRE compatible 3-wire serial interface. It incorporates a power-on reset circuit that clears outputs to zero-scale in internal reference mode.

Feature Summary

Quad 10-bit DACs with integrated 4.096V precision reference (10ppm/°C drift)
AEC-Q100 qualified for automotive applications (-40°C to 125°C)
Rail-to-rail output buffers with ultralow crosstalk (2.4nV•s typical)
Power-on reset to zero-scale in internal reference mode
SPI/MICROWIRE compatible 3-wire serial interface up to 50MHz

Applications

Automotive systems
Process control and industrial automation
Portable equipment
Mobile communications

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging containing 2,500 pieces. Confirm the H-grade designation corresponds to the automotive temperature range of -40°C to 125°C. Ensure the LZ10 configuration matches the required 10-bit resolution and zero-scale power-on reset behavior for internal reference operation.

Selection Notes

Select this part when automotive qualification (AEC-Q100) is required alongside high accuracy. The H-grade variant necessitates a minimum supply voltage of 4.5V, unlike the L-grade which supports 2.7V. Choose the LZ suffix if system initialization requires outputs to clear to zero-scale upon power-up rather than mid-scale.

Part Context

This component belongs to the LTC2634 family of quad DACs available in 8-, 10-, and 12-bit resolutions. The HUD package denotes a 16-lead QFN form factor. The 'H' indicates the 4.096V full-scale internal reference version, while 'LZ' specifies the zero-scale power-on reset option within the internal reference mode.
