LTC2631ACTS8-HZ12#TRPBF

Digital To Analog Converters Overview

The LTC2631ACTS8-HZ12#TRPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features an integrated precision reference with a full-scale output of 4.096V and operates from a 4.5V to 5.5V supply. The device utilizes a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical characteristics include a maximum integral nonlinearity (INL) error of ±1 LSB, a typical settling time of 4.6µs at 5V, and power consumption of 200µA at VCC = 5V. It incorporates a power-on reset circuit that defaults the output to zero-scale upon initialization.

Digital To Analog Converters Feature Summary

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a 2,500-piece tape and reel packaging format. Confirm the H-grade designation corresponds to the automotive temperature range of –40°C to 125°C. Ensure the Z suffix for power-on reset behavior matches system initialization requirements. Cross-reference the ACTS8 package type with PCB footprint specifications.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit DAC with high accuracy (±1 LSB INL) and a 4.096V internal reference is required. The H-grade is necessary for applications operating between –40°C and 125°C. The Z suffix ensures the DAC outputs zero-scale immediately after power-up. Verify that the supply voltage remains within the 4.5V to 5.5V range for specified performance.

Digital To Analog Converters Part Context

This part belongs to the LTC2631 family of single-channel DACs. Variants differ by resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), temperature grade (C, I, or H), and power-on reset state (mid-scale or zero-scale). The 'A' prefix denotes the higher accuracy grade with ±1 LSB INL for the 12-bit version.
