Texas Instruments DAC7621E/1K Digital-to-Analog Converter

The Texas Instruments DAC7621E/1K is a highly precise, 12-bit digital-to-analog converter (DAC) designed to meet the stringent requirements of industrial, communication, and test equipment applications. This advanced DAC offers a flexible serial interface that is compatible with standard SPI, QSPI, MICROWIRE, and digital signal processor (DSP) interfaces.

Key Features

• Resolution: 12-bit
• Interface Type: Serial (SPI, QSPI, MICROWIRE)
• Settling Time: 10µs to 0.003%
• Output Type: Voltage
• Supply Voltage Range: 4.75V to 5.25V
• Operating Temperature Range: -40°C to +85°C
• Packaging: VSSOP-10

The DAC7621E/1K features a bipolar output which provides a swing of ±10V. With its integrated precision output amplifier, this DAC can directly drive the analog load, simplifying design and reducing component count. Its low-power operation and wide temperature range make it suitable for portable and high-temperature applications.

Performance Advantages

The DAC7621E/1K delivers outstanding performance with its low glitch energy and high output drive capability. The device ensures a monotonic output over the entire operating temperature range, guaranteeing reliable and consistent performance in all conditions. Its power-on reset circuitry ensures that the DAC output powers up at zero volts and remains there until a valid write to the device takes place.

Application Versatility

This DAC is ideal for a wide range of applications, including process control, data acquisition systems, closed-loop servo-control, and programmable voltage and current sources. Its compact size and precision make it a perfect choice for portable instrumentation and test equipment.

Quality and Reliability

As with all Texas Instruments products, the DAC7621E/1K is manufactured to the highest standards, ensuring both quality and reliability. The device is available in a small VSSOP-10 package, which is RoHS compliant and designed for optimized board space.
