LTC2631AITS8-LM12#TRMPBF

Overview

The LTC2631AITS8-LM12#TRMPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 2.5V and operates on a single supply voltage ranging from 2.7V to 5.5V. The device utilizes a 2-wire I²C-compatible serial interface supporting clock rates up to 400kHz. Key electrical specifications include a maximum Integral Nonlinearity (INL) error of ±1 LSB and a typical settling time of 4.1µs at 3V. It incorporates a power-on reset circuit configured to initialize the output to mid-scale upon power-up.

Feature Summary

• 12-bit resolution with ±1 LSB maximum INL error
• Integrated 2.5V full-scale reference with 10ppm/°C temperature coefficient
• I²C interface with 400kHz fast mode support
• Power-on reset to mid-scale option

Applications

• Mobile communications
• Process control and industrial automation
• Portable equipment

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration. Confirm that the 'I' temperature grade designation matches the required operating range of –40°C to 85°C for the target application environment.

Selection Notes

Select this part when a 12-bit DAC with high accuracy (±1 LSB INL) and low power consumption is required in a compact TSOT-23 package. Ensure the system supply voltage remains within the 2.7V to 5.5V range compatible with the LTC2631-L series. Verify that the mid-scale power-on reset behavior aligns with system initialization requirements.

Part Context

This component belongs to the LTC2631 family of single-channel DACs. The 'A' suffix denotes the electrical grade with ±1 LSB maximum INL, while 'LM12' specifies the 2.5V full-scale voltage, mid-scale reset, and 12-bit resolution. The 'TS8' indicates the 8-lead TSOT-23 package type.
