Additionally, a power-on reset (POR) circuit is integrated, which clears the DAC output to 0V in unipolar mode when power is initially applied. This ensures a stable and predictable startup sequence.\u003c\/p\u003e\n\u003cp\u003eThe 10MHz 3-wire serial interface is compatible with SPI, QSPI, and MICROWIRE protocols, enabling seamless communication with a wide range of microcontrollers and other devices. Furthermore, the interface can be directly connected to optocouplers, making it suitable for applications that require isolation.\u003c\/p\u003e\n\u003cp\u003eTo provide a stable reference voltage, the\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eREF3025\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003echip is used, which supplies a precise 2.5V reference voltage to the DAC. This ensures that the DAC output is accurate and reliable, making it suitable for a variety of applications that require high-precision voltage output.\u003c\/p\u003e\n\u003cp\u003eThe\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eMAX5541\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003evoltage-output, 16-bit digital-to-analog converter (DAC) offers 16-bit monotonicity with less than 1LSB differential linearity error. Serial-data transfer minimizes the number of package pins required.

This architecture allows the lowest glitch energy to be transferred to the DAC output on major-carry transitions. It also decreases the DAC output impedance by a factor of eight compare to a standard R-2R ladder, allowing unbuffered operation in medium-load applications.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePower Supply 5V DC\u003c\/li\u003e\n\u003cli\u003eFull 16-Bit Performance Without Adjustments\u003c\/li\u003e\n\u003cli\u003eLow Power: 1.5mW\u003c\/li\u003e\n\u003cli\u003e1µs Settling Time\u003c\/li\u003e\n\u003cli\u003eOn Bord Ref-Voltage Chip Output 2.5V (REF3025)\u003c\/li\u003e\n\u003cli\u003eUnbuffered Voltage Output Directly Drives 60kΩ Loads\u003c\/li\u003e\n\u003cli\u003eSPI\/QSPI\/MICROWIRE-Compatible Serial Interface\u003c\/li\u003e\n\u003cli\u003ePower-On Reset Circuit Clears DAC Output to 0V (unipolar mode)\u003c\/li\u003e\n\u003cli\u003eSchmitt Trigger Inputs for Direct Optocoupler Interface\u003c\/li\u003e\n\u003cli\u003eHeader Connector for Serial Interface and output\u003c\/li\u003e\n\u003cli\u003eOn Board Power LED\u003c\/li\u003e\n\u003cli\u003ePCB Dimensions: 20.85 x 15.92 mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":47184405168300,"sku":"C103","price":18.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/C103A.jpg?v=1789113199","url":"https:\/\/dotfry.com\/products\/serial-input-voltage-output-16-bit-dac","provider":"dotfry","version":"1.0","type":"link"}
