The DRV135UAG4 is a low-noise, high performance, four channel variable-gain amplifier from Texas Instruments. This device is primarily used in audio special purpose applications and is well suited for consumer, automotive, and commercial audio applications. The DRV135UAG4 has four fixed ranges of gain, and its gain can be configured in the range of 0 dB to 40 dB with 10 dB steps, making it highly configurable to a range of audio applications. Additionally, the DRV135UAG4 features selectable high-pass filters, low-noise operation, and low-power consumption. The device also features an integrated output reference for the microphones, enabling output signals that are clean and accurate.
The working principle of the DRV135UAG4 amplifier is based on the well-known circuit of Variable Gain Amplifiers (VGA). A VGA is basically a collection of amplifier circuits in different gain stages. The amount of gain in each stage is determined by the input resistors and capacitors. A DC input voltage is applied to the gain selector pins to select the desired gain range. As the DC input voltage is varied, the signal is selectively amplified by the appropriate stage of the VGA. By combining the signal amplifying abilities of each stage, the amplifying range of the VGA is extended to a much greater level than if it were to be amplified by a single gain stage. As the DC input voltage is further varied, the signal is amplified in the same gain range by the same stage of the VGA.
The DRV135UAG4 is optimized for high-performance audio applications, such as digital amplifiers, where low-noise and high-dynamic range operation is essential. The DRV135UAG4\'s gain-selection pins can be used to switch between the four fixed gain stages. The device also provides a precision output reference, which enables it to be used in professional audio systems for optimal performance. Furthermore, the DRV135UAG4 features integrated low-noise filtering and built-in thermal protection, which eliminates the need for additional protection circuitry. This makes the device an ideal solution for use in high-end audio applications.
The DRV135UAG4 is an excellent choice for audio special purpose applications. Its gain selection and integrated filtering capabilities make the device well suited for a range of audio applications, including those with high noise or high-dynamic requirements. Furthermore, its low-power consumption and thermal protection make it an ideal solution for use in high-end audio systems. The precision output reference also allows for optimal performance in professional audio systems. As such, the DRV135UAG4 is an excellent choice for use in a variety of audio special purpose applications.
