TC1321EUATR

Digital To Analog Converters Overview

The TC1321EUATR is a monolithic 10-bit digital-to-analog converter (DAC) manufactured by Microchip Technology. It operates from a single power supply ranging from 2.7V to 5.5V and features a buffered voltage output alongside an unbuffered DAC-OUT pin. Communication is handled via a 2-wire SMBus/I²C serial interface, where the device functions exclusively as a slave. The component includes a Power-on Reset (POR) function and supports a low-power standby mode with typical current consumption of 0.5 µA. It is housed in an 8-pin MSOP package and is designed for industrial temperature ranges between -40°C and +85°C.

Digital To Analog Converters Feature Summary

• Integrates a 10-bit current steering DAC architecture with a buffered rail-to-rail output amplifier.
• Supports simple two-wire SMBus/I²C communication protocols with a fixed default slave address.
• Features a dedicated low-power standby mode accessible through the configuration register.

Digital To Analog Converters Applications

• Programmable voltage sources
• Digital controlled amplifiers and attenuators
• Process monitoring and control systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'TR' confirms tape and reel packaging rather than tube. Confirm the 'UA' suffix corresponds to the 8-lead MSOP package variant. Ensure the 'I' designation matches the required industrial temperature range specifications for your deployment environment.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 10-bit resolution is required with I²C compatibility. Consider the buffered VOUT pin for driving loads directly or the unbuffered DAC-OUT for high-impedance connections. Verify that the external reference voltage requirements align with the specified input range relative to the supply voltage.

Digital To Analog Converters Part Context

This part belongs to the TC1321 family of 10-bit DACs. The 'EUATR' suffix indicates the specific package type (MSOP), temperature grade (Industrial), and shipping format (Tape and Reel). Other variants in the series include SOIC packages and different shipping configurations.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same package and specification profile include the TC1321EUA. Check datasheets for pinout and electrical characteristic compatibility before swapping components in existing designs.

Digital To Analog Converters FAQ

What is the default SMBus slave address for the TC1321?

The TC1321 is internally programmed with a default 7-bit SMBus address value of 1001000b.

How does the device enter Standby mode?

Standby mode is activated by setting the SHDN bit to logic 1 in the CONFIG register, reducing typical supply current to 0.5 µA.

What is the maximum settling time for the DAC output?

The full-scale output voltage settling time is typically 10 µs when loaded with 1 kΩ in parallel with 100 pF.
