LTC2640CTS8-LM8#TRMPBF

Overview

The LTC2640CTS8-LM8#TRMPBF is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing 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 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±0.5 LSB, a typical settling time of 3.2µs at 3V, and a supply current of 180µA at 3V. It incorporates a power-on reset circuit that defaults the output to mid-scale.

Feature Summary

Integrated 2.5V full-scale precision reference with 10ppm/°C temperature coefficient
Rail-to-rail output buffer guaranteed monotonic over temperature
Bidirectional REF pin allows selection between internal or external reference modes
Power-on reset to mid-scale for consistent system initialization

Applications

Mobile communications
Process control and industrial automation
Automatic test equipment
Portable equipment
Automotive systems

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel packaging quantity as defined in the manufacturer's documentation. Confirm the package type is 8-lead TSOT-23 and the temperature grade is Commercial (0°C to 70°C). Ensure compatibility with single-supply operation within the 2.7V to 5.5V range.

Selection Notes

Select this part when an 8-bit resolution is sufficient for the application requirements. The LM suffix designates a mid-scale power-on reset state; choose LZ if a zero-scale reset is required instead. This component is suitable for designs needing a compact 8-lead TSOT-23 footprint and low power consumption under 200µA.

Part Context

This component belongs to the LTC2640 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares a common architecture featuring an integrated low-drift reference and a rail-to-rail output buffer. Variations exist based on resolution, reset behavior, and full-scale voltage options (2.5V or 4.096V).
