LTC2640CTS8-LZ10#TRMPBF

Overview

The LTC2640CTS8-LZ10#TRMPBF is a single-channel, 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a high-accuracy reference with a temperature coefficient of ±10ppm/°C and a full-scale output of 2.5V. The device operates on a single supply ranging from 2.7V to 5.5V and features a rail-to-rail output buffer guaranteed monotonic over temperature. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. It includes a power-on reset circuit that defaults the output to zero-scale.

Feature Summary

10-bit resolution with integrated precision reference providing 2.5V full-scale output
Low drift reference specification of ±10ppm/°C for stable performance
Rail-to-rail output buffer ensuring monotonic operation across the temperature range
Power-on reset function configured to initialize DAC output to zero-scale

Applications

Mobile communications systems
Process control and industrial automation
Automatic test equipment
Portable battery-powered equipment
Optical networking devices

Procurement Notes

Verify the specific suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration as defined in the manufacturer's ordering guide. Confirm the C-grade designation matches the required commercial operating temperature range of 0°C to 70°C for the target application environment.

Selection Notes

Select this component when a single-channel DAC with low power consumption and compact TSOT-23 packaging is required. Ensure the system supply voltage remains within the 2.7V to 5.5V range suitable for the L-grade internal reference. Consider the H-grade variant if a higher 4.096V full-scale output or extended automotive temperature range is necessary.

Part Context

This part belongs to the LTC2640 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The LTS8 package provides an 8-lead ThinSOT form factor designed for space-constrained designs. Variants within the family differ by resolution accuracy, power-on reset behavior, and full-scale voltage capabilities.
