Review BURR BROWN Pcs Lot General Purpose Amplifiers
The Burr-Brown OPA547T is a high-performance dual operational amplifier (op-amp) designed for audio applications. This amplifier chip is a direct upgrade from the popular OPA547, offering enhanced specifications and improved performance.
The OPA547T op-amps are fully differential and feature a low voltage noise floor of just 2.5 nV/ Hz at room temperature. They have a wide bandwidth of 1 MHz and a low power consumption of 11 mA per amplifier when operating from a 15V and -15V power supply. The input voltage range is from -5V to 5V and the output voltage range is from -15V to 15V.
These amplifiers are known for their high common-mode rejection ratio (CMRR) of 110 dB at 1 kHz and 126 dB at 10 Hz, making them well-suited for use in audio applications where common-mode interference is present. They also have a low output impedance of 75 , ensuring that they can drive complex loads such as speakers with ease.
The OPA547T op-amps are available in a compact SO-8 package and are RoHS compliant. They come in a pack of 25 pieces, making them an excellent choice for applications that require multiple amplifiers. The amplifiers are easy to use, requiring only basic external components such as resistors and capacitors to form a complete amplifier circuit.
In summary, the Burr-Brown OPA547T is a high-performance, low noise, and low power dual op-amp that is ideal for audio applications. Its wide bandwidth, high CMRR, and low output impedance make it an excellent choice for driving speakers, microphone preamplifiers, and other audio circuits. The pack of 25 pieces makes it a cost-effective solution for bulk orders.
Burr-Brown OP2547T General-Purpose Operational Amplifiers (OPAs) are widely used in various electronic applications due to their high performance and versatility. Here are some pros and cons of buying 25 pieces of Burr-Brown OP2547T amplifiers:
Pros:1. High gain and low noise: The OP2547T has a high gain bandwidth of 12MHz and a low noise floor, making it suitable for applications that require high gain and low noise.
2. Low power consumption: With a quiescent current of just 1.4mA per amplifier, these devices are energy efficient and suitable for battery-powered applications.
3. Wide range of applications: The OP2547T is a versatile amplifier that can be used in a wide range of applications, including instrumentation, audio, and filters.
4. Good stability: The OP2547T has good stability, with a voltage gain stability of 0.01% and a temperature coefficient of 25ppm/ C.
5. High input and output impedance: The OP2547T has a high input impedance of 10M and a high output impedance of 75 , making it suitable for use with low source and load impedances.
Cons:1. Limited supply voltage range: The OP2547T can operate over a supply voltage range of only 5V to 18V, which may limit its use in certain applications.
2. Relatively high cost: Compared to some other OPAs, the OP2547T can be more expensive, especially when purchasing in smaller quantities.
3. Limited slew rate: The OP2547T has a relatively low slew rate of 0.5V/ s, which may limit its use in high-speed applications.
Conclusion:The Burr-Brown OP2547T is a high-performance, versatile operational amplifier that is suitable for a wide range of applications. Its low noise, high gain, and low power consumption make it an excellent choice for many instrumentation and audio applications. However, its limited supply voltage range, relatively high cost, and relatively low slew rate may be drawbacks for some users.
Recommendation:If you require a high-performance, low-noise operational amplifier with a wide range of applications, the Burr-Brown OP2547T is an excellent choice. However, if you need an amplifier with a wider supply voltage range, a higher slew rate, or a lower cost, you may want to consider other options. In general, the OP2547T is a reliable and high-quality amplifier that is worth considering for many electronic design projects.
