LTC2635CUD-LZ10#TRPBF

Overview

The LTC2635CUD-LZ10#TRPBF 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 2.5V and a temperature coefficient of 10ppm/°C. The device operates on a single supply ranging from 2.7V to 5.5V and includes rail-to-rail output buffers that are guaranteed monotonic over the commercial temperature range of 0°C to 70°C. Communication is handled via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. The part incorporates a power-on reset circuit configured to reset outputs to zero-scale.

Feature Summary

Quad 10-bit resolution with ±1 LSB maximum INL error
Integrated 2.5V precision reference (10ppm/°C)
Rail-to-rail output buffers, guaranteed monotonic
Power-on reset to zero-scale
I²C interface with selectable slave addresses

Applications

Mobile communications
Process control and industrial automation
Power supply margining
Portable equipment

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a lead-free design in a 2,500-piece tape and reel package. Confirm the 'C' grade corresponds to the commercial operating temperature range of 0°C to 70°C. Ensure the 'L' designation matches the required 2.5V full-scale internal reference specification for the application.

Selection Notes

Select this component when a quad-channel DAC with low crosstalk (3nV•s) and ultralow noise (0.75mV P-P) is required. The LZ suffix specifically configures the power-on reset to zero-scale, which differs from mid-scale or high-impedance options. Verify that the 2.7V to 5.5V supply range aligns with the system power architecture.

Part Context

This part belongs to the LTC2635 family, which offers 12-, 10-, and 8-bit resolutions. The CUD package denotes a 16-pin 3mm × 3mm QFN form factor. Other variants include the H-grade for automotive temperatures (-40°C to 125°C) and different reset configurations such as LMI (mid-scale internal) or LMX (mid-scale external).
