LTC2640CTS8-HZ12#TRPBF

Overview

The LTC2640CTS8-HZ12#TRPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a full-scale output of 4.096V and operates on a single supply voltage ranging from 4.5V 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 ±2.5 LSB, a typical settling time of 4.6µs at ±1LSB, and a power-on reset function that clears the output to zero-scale. It is housed in an 8-lead TSOT-23 package.

Feature Summary

Integrated 10ppm/°C precision reference yielding a 4.096V full-scale output
SPI/MICROWIRE compatible 3-wire serial interface supporting up to 50MHz clock rates
Power-on reset circuit configured to clear DAC output to zero-scale
Rail-to-rail output buffer guaranteed monotonic over temperature

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF against official documentation to confirm the tape and reel packaging quantity. Confirm that the C-grade temperature range (0°C to 70°C) aligns with the intended operational environment requirements before procurement.

Selection Notes

Select this part for designs requiring a 4.096V full-scale output with a 12-bit resolution. Ensure the system supply voltage remains within the 4.5V to 5.5V range required for the H-grade internal reference configuration. Verify compatibility with the 3-wire serial interface protocol used by the host microcontroller.

Part Context

This component belongs to the LTC2640 family of single-channel voltage-output DACs. Variants within the family differ by resolution (8-, 10-, or 12-bit), full-scale voltage (2.5V or 4.096V), and power-on reset behavior (zero or mid-scale). All variants share the same 8-lead TSOT-23 physical package and low-power architecture.
