  • Description

    G1421F31UF is a stereo audio power amplifier in a 24pin TSSOP thermal pad package. It has the capability to drive 1.8W continuous RMS power into a 4Ω load per channel in Bridge-Tied Load (BTL) mode with a 5V supply voltage. With a THD smaller than 1% under the mentioned operation condition, it simplifies the audio system design in notebook applications. G1421F31UF supports Bridge-Tied Load (BTL) mode for driving speakers and Single-End (SE) mode for driving headphones. It can also support a DC value to the phone-jacket and drive headphones without the need for audio amplifier output coupling capacitors. The output can be muted when Mute-In is activated, and the device can be disabled using the SHDN mode for low current consumption applications, reducing it to below 5µA.

    Comparison

    Advantages

    - G1421F31UF has a compact package design, making it suitable for limited space applications.
    - It supports various modes, including Bridge-Tied Load (BTL), Single-Ended (SE), and Stereo Headphone Amplifier (HP-IN), providing flexibility in different audio system designs.
    - The device eliminates the need for headphone amplifier output coupling capacitors, simplifying the design and reducing component count.
    - It has integrated depop circuitry and maximum output power clamping circuitry, ensuring high-quality audio performance.
    - The ability to mute the output and the low current consumption in SHDN mode make it energy-efficient.

    Disadvantages

    - G1421F31UF may not be suitable for high-power audio applications that require greater output power.
    - It is designed for 5V supply voltage, limiting its compatibility with systems that operate at different voltage levels.
    - The device is available in a surface-mount power package, which may not be compatible with all assembly methods or require additional considerations for PCB layout.
