Data ampliﬁer and laser supply circuit for CD

audio and video optical systems (ADALASLC)

TZA1025

LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 134).

Notes

1. The maximum value VDD + 0.5 must not exceed 5.5 V.

2. The maximum value VDD(L) + 0.5 must not exceed 5.5 V.

3. Pins DIN and RFFB are current inputs with a limitation on the maximum input current.

4. The maximum peak current must not exceed ten times the absolute average input current with a maximum for the

absolute average input current of 1 mA. Averaging is only allowed over a maximum time interval of 100 ms.

5. Equivalent to discharging a 100 pF capacitor via a 1.5 k

Ω series resistor with a rise time of 15 ns.

6. Equivalent to discharging a 200 pF capacitor via a 2.5

µH series inductor.
