TC1320EOA

Digital To Analog Converters Overview

The TC1320EOA is an 8-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. The device communicates via a two-wire SMBus/I²C compatible serial interface, functioning exclusively as a slave. Key electrical specifications include a typical operating current of 350µA and a standby current of 0.5µA. Integral performance metrics specify ±2 LSB integral non-linearity (INL) and ±0.8 LSB differential non-linearity (DNL). The unit is housed in an 8-pin narrow SOIC package and supports an operating temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates a low-power standby mode activated via the configuration register to minimize energy consumption during idle periods.
• Includes a built-in Power-on Reset function to ensure the device initializes to a known state upon power application.
• Provides both a buffered voltage output for direct driving and an unbuffered DAC output pin for high-impedance connections.

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized Microchip distributors or official sales channels. Confirm that the received units match the specific TC1320EOA designation and package type. Review the latest datasheet revision history for any operational updates or errata sheets prior to finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution with I²C compatibility is required within a 2.7V to 5.5V supply range. Ensure the design accommodates the specified ±2 LSB INL and ±0.8 LSB DNL limits. Verify that the host controller can support the SMBus protocol timing requirements for reliable data transfer.

Digital To Analog Converters Part Context

This part belongs to the TC1320 series of serially accessible digital-to-analog converters. The 'EOA' suffix specifically denotes the 8-pin Narrow SOIC package variant with an industrial temperature rating of -40°C to +85°C. Other variants in the family include MSOP packages and different resolution options like the TC1321.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same package and specification profile are not explicitly listed in the provided documentation. Designers should evaluate other members of the TC132x family or consult Microchip for updated component recommendations if availability becomes an issue.

Digital To Analog Converters FAQ

What is the default SMBus address for the TC1320?

The TC1320 is internally programmed with a default 7-bit SMBus address value of 1001000b.

How does the device handle power-up conditions?

The TC1320 includes a Power-on Reset function that ensures the device starts at a known condition, with a typical reset delay of 500µs.

Can the TC1320 operate with a reference voltage higher than VDD?

No, the VREF input accepts a voltage range from 0V to (VDD – 1.2V), meaning it cannot exceed the supply voltage minus the specified offset.
