TC1321EOA

Digital To Analog Converters Overview

The TC1321EOA 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, with the device acting as a slave. The component includes a Power-on Reset function and supports a low-power standby mode. It is housed in an 8-pin SOIC package and is rated for an operating temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Features a current steering architecture with a buffered rail-to-rail output amplifier.
• Supports low-power operation with a dedicated standby mode accessible via the configuration register.
• Includes a built-in Power-on Reset function to ensure known startup conditions.

Digital To Analog Converters Applications

• Programmable Voltage Sources
• Digital Controlled Amplifiers/Attenuators
• Process Monitoring and Control

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's Product Identification System documentation. Confirm that the package type matches the required form factor, such as the standard Small Outline Package or alternative variants like Tape and Reel options. Ensure the temperature grade aligns with the intended industrial application environment before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a 10-bit resolution is sufficient for the application requirements. Verify that the external reference voltage input remains within the allowable range relative to the supply voltage. Consider the I/O leakage characteristics and the need for high-impedance connections if utilizing the unbuffered DAC-OUT pin for signal routing.

Digital To Analog Converters Part Context

This part belongs to the TC1321 family of serially accessible DACs. The 'E' designation indicates the industrial temperature range (-40°C to +85°C), while 'OA' specifies the 8-lead Small Outline Package. Other variations exist, including MSOP packages and tape-and-reel packaging options, all sharing the same core functional specifications.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other parts within the TC1321 family, such as TC1321VUA or TC1321VOA, provided the package and temperature range requirements are met. Custom SMBus addresses are available upon request from the manufacturer for system integration purposes.
