LTC2640HTS8-HZ12#TRPBF

Overview

The LTC2640HTS8-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 4.5V to 5.5V supply. The device includes a rail-to-rail output buffer guaranteed monotonic over temperature, with a maximum integral nonlinearity error of ±2.5 LSB. It utilizes a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. Power-on reset clears the output to zero-scale, and it is housed in an 8-lead TSOT-23 package.

Feature Summary

12-bit resolution with integrated 4.096V reference
Rail-to-rail buffered output, guaranteed monotonic
Power-on reset to zero-scale
3-wire SPI/MICROWIRE interface

Applications

Mobile Communications
Process Control and Industrial Automation
Automatic Test Equipment
Portable Equipment
Automotive
Optical Networking

Procurement Notes

Verify the H-grade automotive temperature rating (-40°C to 125°C) and the specific #TRPBF tape and reel packaging configuration against the required design specifications. Confirm that the system power supply meets the minimum 4.5V requirement for the internal reference mode operation.

Selection Notes

Select this part when a 12-bit resolution and a fixed 4.096V full-scale range are required within an 8-lead TSOT-23 footprint. Ensure the application environment stays within the -40°C to 125°C operating range. Consider the zero-scale power-on reset behavior if downstream circuits are sensitive to initial DAC states.

Part Context

This component belongs to the LTC2640 family of single-channel DACs. The 'H' suffix denotes the automotive temperature grade, while 'Z' indicates the power-on reset function clears the output to zero-scale. The '12' specifies the 12-bit resolution, and 'TS8' identifies the 8-lead TSOT-23 package type.
