LTC2640AITS8-HZ12#TRPBF

Overview

The LTC2640AITS8-HZ12#TRPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 4.096V and operates within a supply voltage range of 4.5V to 5.5V. The device includes a rail-to-rail output buffer guaranteed monotonic over temperature, with a maximum integral nonlinearity error of ±1LSB. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface supporting clock rates up to 50MHz. Power-on reset options allow the output to initialize to zero-scale or mid-scale.

Feature Summary

12-Bit Resolution with ±1LSB Maximum INL
Integrated 4.096V Reference (10ppm/°C Drift)
SPI/MICROWIRE Compatible 3-Wire Serial Interface
Power-On Reset to Zero-Scale

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a 2,500-piece tape and reel packaging format. Confirm the H-grade designation corresponds to the automotive temperature range of –40°C to 125°C. Ensure the Z suffix is correctly interpreted as the power-on reset to zero-scale configuration for system initialization requirements.

Selection Notes

Select this component when a single-channel DAC with high accuracy (±1LSB INL) and low drift is required in a compact 8-lead TSOT-23 package. Choose the H-grade variant if operation above 85°C is necessary, noting the higher minimum supply voltage requirement of 4.5V compared to the L-grade. Verify that the 4.096V internal reference range matches the application's output span needs.

Part Context

This part belongs to the LTC2640 family of single-channel DACs available in 12-, 10-, and 8-bit resolutions. The family distinguishes between L-grade (2.7V–5.5V supply, 2.5V FS) and H-grade (4.5V–5.5V supply, 4.096V FS) variants. The A grade specifically denotes the tighter ±1LSB linearity specification for the 12-bit version.
