Digital to Analog Converters (DACs) are devices that are used to convert a digital signal into an analog signal. The most common types are voltage-to-frequency converters, and current-to-frequency converters. These are used in a wide variety of applications, such as home audio systems, recording equipment, musical instruments, and automotive audio systems. The DAC102S085EB/NOPB is a voltage-to-frequency DAC from Texas Instruments that is specifically designed for audio applications.

Application Field

The DAC102S085EB/NOPB is designed to be used in professional audio applications, such as pro-audio mixing boards, studio monitors, and professional amplifiers. It can be used for a wide variety of applications, including noise shaping, crossover networks, and dynamic range compression. The device has a wide dynamic range of up to 105dB, and can be configured to a voltage range of up to 5V. It has low distortion and low power consumption, making it suitable for a wide range of applications.

Working Principle

The DAC102S085EB/NOPB uses an internal voltage-to-frequency converter to convert an input voltage into an analog signal. The circuit consists of a comparator, a frequency divider, and a sample-and-hold element. The comparator looks at the input voltage and compares it to a reference voltage. If the input voltage is higher than the reference voltage, then the frequency divider will divide the clock signal, resulting in a lower frequency output. If the input voltage is lower than the reference voltage, then the frequency divider will multiply the clock signal, resulting in a higher frequency output. The sample-and-hold element is used to keep the output signal at the same frequency, even when the input voltage is changing. This ensures that the output signal follows the input signal accurately. The device can be configured to have a voltage output of up to 5V, and the frequency range can be set to between 20Hz-20kHz.

The DAC102S085EB/NOPB is a powerful and versatile voltage-to-frequency DAC that is ideal for pro-audio applications. Its wide dynamic range, low distortion, and low power consumption make it well suited for a wide range of professional audio applications.
