LTC2640CTS8-LZ10#TRPBF

Overview

The LTC2640CTS8-LZ10#TRPBF is a single-channel, 10-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 SPI/MICROWIRE compatible 3-wire serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a settling time of 3.8µs at 3V, and a typical supply current of 180µA. It incorporates a power-on reset circuit that defaults the output to zero-scale.

Feature Summary

Integrated 10ppm/°C precision reference with 2.5V full-scale output
SPI/MICROWIRE compatible 3-wire serial interface supporting up to 50MHz clock
Power-on reset to zero-scale for consistent system initialization
Rail-to-rail output buffer guaranteed monotonic over temperature

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF corresponds to the 2,500-piece tape and reel packaging configuration as defined in the manufacturer's documentation. Confirm that the C-grade temperature rating (0°C to 70°C) aligns with the operational environment requirements. Ensure the package type matches the 8-lead TSOT-23 form factor specified for this part number.

Selection Notes

Select this component when a single-channel DAC with low power consumption and high accuracy is required. The 10-bit resolution offers a balance between cost and performance. The internal 2.5V reference eliminates the need for external components, simplifying board layout. Verify that the supply voltage range of 2.7V to 5.5V meets the system power constraints.

Part Context

This part belongs to the LTC2640 family of single voltage-output DACs available in 12-, 10-, and 8-bit resolutions. The 'L' designation indicates the 2.5V full-scale version powered by a 2.7V to 5.5V supply. The 'Z' suffix specifies the power-on reset behavior to zero-scale, while 'TS8' denotes the 8-lead ThinSOT package.
