TDA1190Z

The TDA1190Z can give an output power of 4.2W(d=10%)into a 16 load at Vs=24V,or 1.5W (d=10%)into an 8load at Vs=12 V.This performance, together with the FM-IF section characteristics of high sensitivity, high AM rejection and low distortion, enables the device to be used in almost every type of television receivers.The device has no irradiation problems, hence no external screening is needed.

The TDA1190Z has the following features including:(1)if limiter-amplifier; (2)active low-pass filter; (3)FM detector; (4)DC volume control; (5)AF preamplifier; (6)AF output stage.The electrical characteristics of the TDA 11902 remain almost constant over the frequency range of 4.5 to 6 MHz, therefore it can be used in all television standard (FM mod.).The TDA1190Z has a high input impedance, so it can work with a ceramic filter or with a tuned circuit that provide the necessary input selectivity.The value of the resistors connected to pin 7, determine the AC gain of the audio frequency amplifier.This enables the desired gain to be selected in relation to the frequency deviation at which the output stage of the AF amplifier must enter into clipping.

The absolute maximum ratings of the TDA1190Z are:(1)supply voltage:28V;(2)output peak current(non-repetitive):2A;(3)power disspation:5W; (4)storage and junction temperature:-40 to 150; (5)output peak current(repetitive):1.5A.The  capacitor connected  between  pin  12 and ground, toghether with the internal resistor of 10 K, forms the de-emphasis network.The Boucherot cell eliminates the high frequency oscillations caused by inductive load and the wires connecting the loud-speaker.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics. Before ordering, purchasers are advised to contact the Sensitron Semiconductor sales department for the latest version of the datasheet(s).In cases where extremely high reliability is required (such as use in nuclear power control, aerospace and aviation, traffic equipment,medical equipment, and safety equipment), safety TDA1190Z should be ensured by using semiconductor devices that feature assured safety or by means of users' fail-safe precautions or other arrangement.
