STK401-020 - Sanyo Semicon Device

STK401-020 AF Power Amplifier

of External Circuits C1, 11 For input coupling capacitor. Used for DC current blocking. When capacitor reactance with low frequency is increased, the reactance value should be reduced in order to reduce the output noise from the signal resistance dependent 1/f noise. In response to the popping noise which occurs when the system power is turned on, C1 and C11.

Features

• Pin-compatible STK400-000 series (3-channel/single package) STK401-000 series (2-channel/single package)
• Output load impedance RL=6Ω/3Ω supported
• New pin arrangement To simplify input/output pattern layout and minimize the effects of pattern layout on operational characteristics, pin assignments are grouped into blocks consisting of input, output and power systems.
• Few external circuits Compared to those series used until now, boot-strap capacitors and boot-strap resistors for external circuits can be greatly reduced. ¥ Specifications Maximum Ratings at Ta = 25°C Parameter Maximum su.
