Vacuum cleaner STWA. When driving a 4 load off a 9V supply, the BAA does not require a heatsink. The BA uses a lost-cost package. The basic characteristics total harmonic distortion etc. Application Radio cassette players. Features 1 High output. Output is not influenced by the standby pin voltage. Symbol VCC Min. Block diagram T. Measurement circuit T. Operation notes 1 Input circuit The structure of the input circuit is shown in Fig.
The IC can be used without coupling capacitors, but a maximum of 0. To prevent degradation of the IC characteristics, the input bias resistor is not built into the IC. We recommend that you set the gain to 30dB or higher. S pin and the VCC pin for oscillation prevention be a metal-film component with good temperature and high-frequency characteristics.
Ceramic capacitors have poor temperature characteristics, so if used, allow sufficient oscillation margin. It is also possible to connect a capacitor for oscillation prevention between the output and GND C2. The oscillation margin depends on the PCB pattern and the mounting position of the capacitor. GND and Pow. GND are joined at pin12, so there is a chance of crosstalk or degraded distortion performance due to common ground impedance in the PCB pattern.
Design the PCB after referring to the application example PCB the recommended value for the power supply capacitor is F of greater. The on voltage V1 can be in the range 3V to VCC, so the standby switch will not adversely influence circuit characteristics as with conventional methods.
This also increases design freedom. The ripple rejection can be increased somewhat by increasing the capacitance, but this also affects the starting time, so we recommend a value in the range F to F. The standard starting time is 0. During normal operation, operate the IC within its recommended operating voltage range; exceeding this range will result in destruction of the IC.
However, we recommend that you confirm the characteristics of the circuit in actual use. If you change the circuit constants, check both the static and transient characteristics of the circuit, and allow sufficient margin to accommodate variations in both ICs and external components.
