TDA1566 Audio Amplifier 2x46W / 1x92W

TDA1566 general description:

The TDA1566 is a car audio power ampliﬁer with a complementary output stage realized in BCDMOS. The TDA1566 has two Bridge Tied Load (BTL) output stages and comes in a HSOP24 or DBS27P package. The TDA1566 can be controlled with or without I2C-bus. With I2C-bus control gain settings per channel and diagnostic trigger levels can be selected. Failure conditions as well as load identiﬁcation can be read with I2C-bus. The load identiﬁcation detects whether the outputs of a BTL channel are connected with a DC or AC load and discriminates between a speaker load, a line driver load and an open (unconnected) load. The TDA1566 can be conﬁgured in a single BTL mode and drive a 1 Ω load. For the single BTL mode it is necessary to connect on the Printed-Circuit Board (PCB) the outputs of both BTL channels in parallel. TDA1566 Audio Amplifier 2x46W / 1x92W

One Chip AM/FM Radio with Audio Power Amplifier

Description: The integrated circuit TDA1083 includes, with exception of the FM front end, a complete AM-/FM-radio-circuit with audio power amplifier. An internal Z-diode stabilizes the supply voltage at VS 13 V, which allows with the aid of a resistor and a rectifier, the circuit to be driven by a higher external supply voltage. Features: Large supply voltage range VS = 3 to 12 V High AM-Sensitivity Limiting threshold voltage Vi = 50 V Audio output power P0 = 0.7 W AFC-connection for VHF-tuner AM-FM switching without high frequency voltages Applications: AM-/FM- and audio-amplifier Circuit Diagram: Circuit diagram for One Chip AM/FM Radio with Audio Power Amplifier Datasheet for TDA1083: Download

200W Hybrid Audio Amplifier Circuit

200W Hybrid Audio Amplifier Circuit - c onnecting two TDA2030 thru cheap power transistors we can create a amplifier wich can deliver a higher power. With the components value from the schematic the total amplifier gain is 32 dB. The speaker can be 2 ohm instead of 4 ohm if we use the TIP transistors. TDA 2030 is produced by SGS Ates and is a complete audio amplifier. AB class of the final amplifier cand deliver up to 14W on 4 ohm at a +-14V power supply. With a proper designed power supply this audio amplifier can output 200W. Active components: IC1, Ic2 TDA 2030 T1, T3 = BD 250, TIP 36 T2,T4 = BD 249, TIP 35 D1 … D4 = 1N4001 200W Hybrid Audio Amplifier Circuit
