4 x 45W Audio Power Amplifier

General description:
The TDA8595 is a complementary quad Bridge Tied Load (BTL) audio power amplifier made in BCDMOS technology. It contains four independent amplifiers in BTL configuration. Through the I2C-bus, diagnosis of temperature warning and clipping level is fully programmable and the information available via two diagnostic pins is selectable. The status of each amplifier (output offset, load or no load, short-circuit or speaker incorrectly connected) can be read separately.
Features and benefits:
Operates in legacy mode (non I2C-bus) and I2C-bus mode (3.3 V and 5 V compliant)Three hardware-programmable I2C-bus addressesDrive 4  or 2  loadsSpeaker fault detectionIndependent short-circuit protection per channelLoss of ground and open VP safe (with 150 m series impedance and a supply  decoupling capacitor of 2200 F maximum)All outputs short-circuit proof to ground, supply voltage and across the loadAll pins short-circuit proof to groundTemperature-controlled gain reduction to …

2 x 23 W high efficiency car radio power amplifier

FEATURES:
Low dissipation due to switching from Single-Ended (SE) to Bridge-Tied Load (BTL) mode High Common Mode Rejection Ratio (CMRR) Mute/standby/operating/SE-only (mode select pin) Zero crossing mute and standby circuit Load dump protection circuit Short-circuit safe to ground, to supply voltage and across load Loudspeaker protection circuit Device switches to single-ended operation at excessive junction temperatures.
GENERAL DESCRIPTION:
The TDA1561Q is a monolithic power amplifier in a 13 lead single-in-line (SIL) plastic power package. It contains two identical 23 W amplifiers. The dissipation is minimized by switching from SE to BTL mode, only when a higher output voltage swing is needed. The device is primarily developed for car radio applications.
