DAC7578SPWR

Digital To Analog Converters Overview

The DAC7578SPWR is a monolithic, low-power, voltage-output digital-to-analog converter featuring eight independent channels with 12-bit resolution. It utilizes a versatile two-wire serial interface compatible with I2C standards, supporting clock rates up to 3.4 MHz. The device operates on a single analog power supply ranging from 2.7 V to 5.5 V and includes an integrated power-on-reset circuit that ensures outputs initialize to zero-scale or midscale. Designed for high linearity and minimal transient voltages, it offers a settling time of 12 µs under standard load conditions.

Digital To Analog Converters Feature Summary

• Ultra-low glitch energy design minimizes undesired code-to-code transient voltages.
• Integrated power-on-reset circuit guarantees defined output states upon initialization.
• Versatile two-wire serial interface allows multiple devices to share the same bus.
• Low power consumption supports battery-operated portable equipment applications.

Digital To Analog Converters Applications

• Portable instrumentation
• Closed-loop servo control
• Process control systems
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP-16 package configuration required for your PCB layout. Confirm that the component meets RoHS compliance standards if mandated by your manufacturing regulations. Ensure the external reference voltage source aligns with the specified input range to maintain accuracy specifications across the operating temperature range.

Digital To Analog Converters Selection Notes

Select this component when eight simultaneous voltage outputs are required within a compact footprint. Consider the DAC7578 over lower-resolution variants if precise 12-bit linearity is critical for the application. Evaluate the power-down current specifications against system standby requirements to ensure optimal energy efficiency during inactive periods.

Digital To Analog Converters Part Context

This device belongs to the DACx578 family, which also includes the 8-bit DAC5578 and 10-bit DAC6578. All members share identical pinouts and functionality, differing primarily in resolution and relative accuracy specifications. The DAC7578 serves as the highest precision option within this specific series, offering 1 LSB INL performance.

Digital To Analog Converters Replacement Considerations

The DAC7678 is functionally compatible and pin-compatible with the DAC7578. Note that the DAC7678 incorporates an internal reference, whereas the DAC7578 requires an external reference source. Verify schematic compatibility regarding reference voltage routing before substitution.
