Introduction

Data acquisition - digital to analog converters (DACs) are fundamental components in many modern technologies. The LTC2630AHSC6-HZ12 is a twelve-bit, voltage-output DAC that offers excellent dynamic performance and is ideal for a wide range of applications.

Application Field

The LTC2630AHSC6-HZ12 is an ideal choice for systems requiring low noise output and excellent dynamic performance. Its twelve-bit accuracy allows it to provide an extremely wide range of analog voltage outputs—from 0V to 12V with a 0.25V step size. This makes it suitable for applications that require precise signal levels over a wide dynamic range.Applications for the LTC2630AHSC6-HZ12 include signal generation, signal amplification, signal conditioning, control systems, and test and measurement systems. It can also be used in automotive, industrial, and medical devices.

Working Principle

The DAC operates on the basic principle of digital-to-analog conversion, which involves translating a digital signal consisting of a series of binary numbers into a corresponding analog voltage or current. The DAC works by adding or subtracting an increment of the input signal (expressed in volts) to the output voltage. This process is controlled by a reference voltage and a feedback loop, which ensures the accuracy and stability of the output signal.The LTC2630AHSC6-HZ12 utilizes a standard R-2R ladder architecture to produce its analog output. An R-2R ladder consists of a network of resistors and switches that convert a digital input signal into a corresponding analog output. When a logic “1” is applied to a resistor, it is connected to the reference voltage. When a logic “0” is applied, the corresponding resistor is connected to ground. The resulting voltage is then amplified and buffered, producing an analog output.The LTC2630AHSC6-HZ12 is capable of outputting an extremely low voltage—as low as 1mV—with 0.25mV resolution. It also offers fast settling times, low noise performance, and excellent power supply rejection. It can operate from a single supply voltage of 1.7V to 5.5V and consumes only 70µA of quiescent power.

Conclusion

The LTC2630AHSC6-HZ12 is a twelve-bit, voltage-output DAC designed for a wide range of applications. It is ideal for systems requiring low noise output, fast settling times, low-voltage operation, and excellent power supply rejection. Its R-2R ladder architecture enables high-precision conversions with resolution down to 0.25mV. This makes it an excellent choice for a variety of data acquisition and signal conditioning tasks.
