Pre-ampliers for CD-RW systems
TZA1020; TZA1020A
Notes
1. In the application, the reference current will be generated by means of a resistor. The given current can be realized
by a resistor of 1.3844 k
. As these are not available, the actual reference current will be slightly different. This
means that all derived signal currents will be scaled in the same way
.
2. IC1 =IC2 =IC3 =IC4 =10 A; ISA1 =ISA2 =ISB1 =ISB2 = 1.25 A; Inegain =50 A; Isdne =20 A; IRREF = 900 A;
Icagain =35 A; ERON = 1.
3. The voltage on TLN can be clamped with respect to GND (positive and negative) with one or two diodes. The clamp
has an internal resistance of approximately 900
.
4. In the TZA1020A, pin MIRN is clamped with respect to GND (positive) by means of one diode.
5. IC1 =IC2 =IC3 =IC4 =25 A; ISA1 =ISA2 =ISB1 =ISB2 = 3.125 A; Isdfine =20 A; IRREF = 900 A.
6.
7. IC1 =IC2 =IC3 =IC4 =25 A; ISA1 =ISA2 =ISB1 =ISB2 = 3.125 A.
8. Ci = total capacitance connected to all input pins C1 to C4 (between pin and ground).
9.
ΣIC1 = 2e-3.(1 + 0.7 sin(12π.3e6.t)) A; ISA1 =ISB1 =ISA2 =ISB2 =25 A; IMIRN =15 A; Ialphagain =50 A;
Isumref =15 A; IAZIN = 100 A; AMON = 1; alphactrl(2 to 0) = 000; algctr4 = 00; algctr6 = 1; algctr5 = 0;
ICAGAIN = 200 A.
10. IC1 =IC2 =IC3 =IC4 =25 A; Ippnscl =50 A; ppnctrl1 = 1, ppnctrl2 = 1.
11. Bandwidth =
