DAC7718SRGZR

Digital To Analog Converters Overview

The DAC7718SRGZR is an octal, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a resistor-string architecture with buffered voltage outputs capable of reaching high voltages. The device supports serial input interfaces including SPI, Microwire, and QSPI. It operates on a single analog supply ranging from 4.5 V to 18 V and a digital supply from 2.7 V to 5.5 V. Key performance metrics include a maximum settling time of 15 µs, integral nonlinearity (INL) of ±1 LSB, and differential nonlinearity (DNL) of ±1 LSB. The component functions within a temperature range of -40°C to +105°C and is housed in a 48-VQFN package.

Digital To Analog Converters Feature Summary

• Octal configuration providing eight independent 12-bit channels for multi-channel signal generation.
• High-voltage output capability allowing direct drive of industrial loads without external amplification.
• Low-power design utilizing a resistor-string architecture for efficient operation.
• Flexible serial interface compatibility supporting standard DSP and microcontroller protocols.

Digital To Analog Converters Applications

• Industrial process control systems requiring multiple isolated analog outputs.
• Programmable logic controller (PLC) modules for sensor simulation.
• Data acquisition systems needing precise voltage reference distribution.
• Automotive test equipment requiring stable high-voltage analog signals.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when ordering. Confirm that the 48-VQFN footprint matches the target PCB layout constraints. Ensure the design accounts for the specified thermal dissipation requirements under the maximum operating temperature conditions defined in the datasheet.

Digital To Analog Converters Selection Notes

Select this component when eight synchronized 12-bit channels are required with high-voltage output swings. Compare against the DAC8718 if higher 16-bit resolution is necessary, or the DAC7718SRGZT if cut-tape quantities are preferred over reel packaging. Validate that the serial interface timing meets the system clock requirements.

Digital To Analog Converters Part Context

This part belongs to the DAC7718 family of octal digital-to-analog converters. It shares architectural similarities with the DAC8218 but offers lower 12-bit resolution compared to the 16-bit DAC8718. The SRGZR variant specifically denotes the surface-mount VQFN package delivered in a reel format for automated assembly processes.

Digital To Analog Converters Replacement Considerations

The DAC7718SRGZT serves as a functional equivalent with identical electrical specifications, differing only in packaging format (cut tape versus reel). The DAC8218 provides similar functionality with increased 14-bit resolution. Verify pinout compatibility before substituting these alternatives.
