DAC121C081CISDX/NOPB - Texas Instruments 12-Bit Digital-to-Analog Converter

The DAC121C081CISDX/NOPB is a highly precise 12-bit Digital-to-Analog Converter (DAC) designed by Texas Instruments to provide a cost-effective solution for demanding applications requiring high-resolution digital-to-analog conversion. This integrated circuit features a single DAC channel with an output voltage range that can be set by an external reference voltage, offering flexibility for various output requirements.

The device operates from a single 2.7V to 5.5V power supply, making it suitable for battery-powered and portable applications. It also boasts a low-power consumption profile, with a typical active mode current of just 210 µA and a power-down mode that reduces the current to 0.4 µA, thereby extending battery life in portable devices.

The DAC121C081CISDX/NOPB communicates via an I²C-compatible serial interface, which supports standard (100 kbps), fast (400 kbps), and high-speed (3.4 Mbps) modes. This interface allows for easy connection to microcontrollers and other digital systems, making the DAC an ideal choice for a wide range of applications including process control, data acquisition systems, and digital gain and offset adjustment.

With its built-in precision internal reference, the DAC121C081CISDX/NOPB ensures accurate and stable output performance. The device also features a power-on reset circuit that ensures the DAC output powers up at zero volts and remains there until a valid write to the device takes place. This feature is critical for applications that require a predictable startup behavior.

The DAC121C081CISDX/NOPB is available in a tiny 6-pin WSON package, making it an excellent choice for space-constrained applications. In addition, the device is specified over the extended industrial temperature range of -40°C to +105°C, ensuring reliable performance across various environmental conditions.

Texas Instruments' commitment to quality and reliability is evident in this product, which is designed to meet the stringent requirements of industrial and commercial applications. The DAC121C081CISDX/NOPB is a versatile and reliable component for any system requiring high-precision analog output.
