Tosnipa NTEGRATED CIRCUIT TAT240AP -TAT24 AP TECHNICAL DATA AMP.1 is noninverting amplifier and AMP.2 is inverting one. The output voltage is divided by resistors R5 and Ro. This divided voltage is applied to inverting input of AMP.2. R5 and R6 are determined in the following equation. _RStRE _ yn R'tRet+RQ" R3'+Ry! ev in D RS 20 fog RR 20 Fog a rae v in Dual Mode The voltage gain in this circuit is 6dB higher than that in dual mode Ry+RE+R2 R3+R4 fan} by = 2 ast + (dB!) Gy 0 log RitRe 20 Fog Ra 6 dB In case of Rf=0 Gy=52+6= 58! dB} In case of Rf=7502 Gy=34+6=40(dB} 2. MUTING Audio muting can be accomplished by connecting pin 3 (ripple filter) to GND as shown in Fig.3. Then, the bias circuits are cut off. off on Amount of muting attenuation is more than 60dB. ce sw Precaution in muting operation is as follows. (1) The recovery time at muting off depends on Fig.3 Capacitance C2, C4 and C5 in the test Circuti. (2) As this muting system is operated by the shart-circuit of ripple filter : C5, the ripple rejection ratio becomes warse in a muting mode. Note that some "POP-Noise" occur when bias is shut off with mute-on. 3. CAPACITOR C7, Cg The purpose of capacitor C7, Cg is to prevent oscillation. These capacitors need to be small temperature coefficient. So celamic capacitor is unsuitabel. A voltage gain less than 40dB results occasionally in a parastic oscillation. Stability for parastic oscillation is promoted by connecting capacitor of 500 1000pF between pin@ and pin@ (pin@® and pin®@ ). The additional capacitors are recommended to be inserted. 240AP-4 1989-4-4 peg TOSHIBA CORPORATION

TosHipa NTEGRATED CIRCUIT TAT7240AP ,TA7241AP TECHNICAL DATA 4. PRECAUTION AT PRINT BOARD DESIGN (1) Print Pattern board should be designed in consideration of stability for parastic oscillation. The following parts-layout is recommended. lst. Capacitors C6 and Cio are spaced most close to the output pin. 2nd. Capacitor C7 or Cg is spaced close to the output pin next to C6 and Clo. 3rd. Capacitor C9 is spaced close to it next to C7 and Cg. 4th. Capacitor C1] is spaced close to it next to Cg. (2) Input line (pin ®) and PW-GND line (pin@) should not be spaced in parallel. In the paralled layout, output current signal in PW-GND line is bed back to input line by electromagnetic coupling. Then it deteriorates the total harmonic distortion, especially at high audio frequency region. (3) Undesirable terminating of capacitors deteriorates "pop" noise or THD. Capacitors C2, C4 and C5 should be terminated to Pre-GND (pin@). Capacitors C7, C11, and C14 should be terminated to PW-GND (rin@). (4) It is recommended to refer the standard print board.
