Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO representative nearest you before using any SANYO products described or contained herein in such applications. SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other parameters) listed in products specifications of any and all SANYO products described or contained herein.

Sample Application Circuit : Equalizer Amplifier with Automatic Level Control designed for Cassette Tape Recorder, Radio
Description of External Parts C1 : Input coupling capacitor (10F) DC current blocking capacitor used to prevent the DC current applied to the base from mixing in the AC signal source. The C1 is calculated using C1=1/2fTzi (zi : input resistance, fT : low cutoff frequency). If the capacitance value is too decreased, your set is subjected to inductive hum. We recommend using a capacitor of 2.2F or greater. We also recommend using 6.3WV or greater because the chemical capacitor becomes less leaky as the withstand voltage gets higher. C2 : Decoupling capacitor (33F) Used to bypass the power source ripple. Decreasing the capacitance value makes the starting time shorter. We recommend using a capacitor of 33F. C3 : Bypass capacitor (100F) Used to AC-Short the emitter resistance and prevent AC components from being fed back to the input. C4 : Output capacitor (10F) Used to block DC components and pass AC Components only. The C4 is calculated using C4=1/1fL * RL (fL : low cutoff frequency, RL : load resistance). C5 : Phase compensation capacitor (30pF) Used to prevent high-frequency oscillation caused by phase shift when a deep feedback is provided. It should be noted that the high frequency response depends on the capacitance value of C5. Continued on next page.

Continued from preceding page. R1 : Decoupling resistor used to bypass the power source ripple through C2. R2 : Collector resistor of the first stage transistor of IC. Taken as load resistance in terms of AC. C6, R3, R4 : Equalizer parts on which the closed-loop voltage gain depends. NAB 4.75cm/s is provided.

Proper Cares in Using IC 1. If the IC is used in the vicinity of the maximum rating, even a slight variation in conditions may cause the maximum rating to be exceeded, thereby leading to a breakdown. Allow an ample margin of variation for supply voltage, etc. and use the IC in the range where the maximum rating is not exceed. 2. Pin-to-pin short If the supply voltage is applied when the space between pins is shorted, a breakdown or deterioration may occur. When installing the IC on the board or applying the supply voltage, make sure that the space between pins is not shorted with solder, etc.

Specifications of any and all SANYO products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer's products or equipment. SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all semiconductor products fail with some probability. It is possible that these probabilistic failures could give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design.
