PHILIPS TDA1522 Data Sheet
Summary
This datasheet describes the Philips TDA1522 stereo cassette head preamplifier and equalizer designed for car radio/cassette player applications. The device contains two independent amplifiers with 90dB typical open-loop gain and internal DC feedback via 140kΩ resistors, eliminating the need for input coupling capacitors since the head input references DC ground. AC equalization characteristics are set externally via an RC network, with stability maintained down to a gain of 30dB. Key specificat

Frequently Asked Questions
What is the required supply voltage range for the device?
The operating supply voltage (pin 8) must be between 7.5 V and 23 V.
How can I determine the open-loop gain of the preamplifier?
The general description notes an open-loop gain of 90 dB (typical).
What are the limits for total power dissipation?
The allowable maximum total power dissipation (tot) is -800 mW.
If I use the mute function, what voltage must be applied to pin 2 when it is active or inactive?
Mute ON requires a voltage of 0-1V, while Mute OFF needs a minimum of 7.5 V.
