Review SEMICONDUCTOR CIRCUITS INC Inc. Power Source 5/17v

The PA23-020 power amplifier circuit from Texas Instruments, specifically the SP6489 version, is a high-performance, monolithic micropower audio power amplifier designed for low power portable applications. This amplifier circuit can deliver a maximum output power of 1 watt into a 4 ohm load, making it suitable for powering a variety of small speakers or headphones.

The PA23-020 operates on a supply voltage range of 5V to 17V and features a low quiescent current of just 4.7mA, making it an ideal choice for battery-operated devices. It is also compliant with the EN55011 Class B conduced and radiated emission standards, ensuring minimal electromagnetic interference.

This amplifier circuit utilizes Texas Instruments' patented PowerOrchard technology which optimizes power supply and audio output stages to achieve high efficiency and minimal power consumption. It also includes a built-in current limiting feature to protect against short circuits and overloads.

The PA23-020 features a simple single-supply operation, making it easy to integrate into various audio systems. It also includes a thermal shutdown feature that automatically turns off the amplifier when it exceeds a safe operating temperature, ensuring reliable operation and extended lifespan.

The SP6489 version of the PA23-020 power amplifier circuit from Texas Instruments is a versatile and efficient solution for powering small audio systems in battery-operated devices. With its high power output, low quiescent current, and compliance with electromagnetic interference standards, it offers excellent performance and reliability for a wide range of applications.

The PA23-020 power amplifier chip from Texas Instruments and the SP6489 power supply regulator from ON Semiconductor are two separate components used in electronic circuits. Let's discuss the pros and cons of buying these components individually.

1. High Power Density: The PA23-020 can deliver 23W of output power from a small 14-pin package, making it ideal for space-constrained applications.

2. Low Quiescent Current: This power amplifier has a low quiescent current, which reduces power consumption when not in use.

3. High Voltage Gain: With a voltage gain of up to 16dB, the PA23-020 can effectively amplify input signals.

4. Wide Operating Temperature Range: The chip can operate at temperatures ranging from -40 C to 85 C, making it suitable for various environments.

1. Limited Input Voltage Range: The input voltage range is relatively narrow, which may necessitate additional components to ensure proper voltage levels for the power amplifier.

2. Sensitivity to Input Signal: The PA23-020 is sensitive to input signal levels and may require careful calibration to ensure optimal performance.

1. Wide Input Voltage Range: The SP6489 can accept input voltages ranging from 10V to 36V, making it adaptable to various power sources.

2. High Load Current: This regulator can supply up to 1.2A of continuous current, which is sufficient for many low-power applications.

3. Low No-Load Voltage Ripple: The SP6489 exhibits a low no-load voltage ripple, ensuring stable output voltage levels.

1. Limited Output Voltage Range: The regulator can only output voltages between 5V and 17V, which may not be suitable for all applications.

2. Higher Quiescent Current: The SP6489 has a higher quiescent current compared to some other regulators, which increases power consumption.

Both the PA23-020 power amplifier chip and the SP6489 power supply regulator offer unique advantages and challenges. The PA23-020 is ideal for applications requiring high power density and low quiescent current, while the SP6489 is suitable for applications with a wide input voltage range and high load current requirements.

When deciding whether to purchase the PA23-020 power amplifier chip and the SP6489 power supply regulator, consider the specific requirements of your application. If you need a power amplifier with high power density and low quiescent current, the PA23-020 is a good choice. However, if you require a power supply regulator with a wide input voltage range and high load current capacity, the SP6489 would be a better fit. It's essential to evaluate the trade-offs and select the components that best meet your project's needs.

Details:

The SP6489 series ensures reliability and performance in industrial commercial applications, making it an essential component for businesses settings that require stable consistent power sources.
