Wide bandwidth
The all discrete topology allows the σ22 to be optimally tuned for the best combination of wide bandwidth and solid stability. Since the σ22's output impedance is much lower than even the best low-ESR large aluminum electrolytic capacitors, having wide bandwidth allows the σ22 to respond to fast changing current demands better than a large capacitor (or a bank of capacitors) ever would.
σ22's bandwidth extends beyond the audio band, and maintains supremely low output impedance in the μΩ range. (in fact, the hookup wire will dominate the output impedance).
As such, only a 1μF decoupling capacitor is used on each output rail onboard the σ22. The PSU can supply an amplifier with little additional capacitance for very fast response.
σ22 is also stable with a large capacitive load (tested to 10000μF), making it suitable for use in a wide variety of applications.
宽带宽
全离散拓扑结构可对σ22进行最佳调整,以实现宽带宽和稳固性的最佳组合。 由于σ22的输出阻抗甚至比最好的低ESR大型铝电解电容器低得多,因此具有较宽的带宽使σ22可以比大型电容器(或一组电容器)更好地响应快速变化的电流需求。
σ22的带宽扩展到音频频带之外,并在μΩ范围内保持极低的输出阻抗。 (实际上,连接线将主导输出阻抗)。
因此,在σ22的每个输出轨上仅使用一个1uuF去耦电容器。 PSU可以为放大器提供很少的附加电容,以实现非常快的响应。
σ22在较大的电容性负载(经测试为10000μF)下也很稳定,使其适用于多种应用。 |
