They are designed for use in TV and monitors, but also suitable for battery-fed portable • Mute mode recorders and radios. • Thermal protection • Short-circuit proof Missing Current Limiter (MCL) • No switch-on and off clicks A MCL protection circuit is built-in. The MCL circuit is • Good overall stability activated when the difference in current between the output terminal of each amplifier exceeds 100 mA (typical • Low power consumption 300 mA). This level of 100 mA allows for headphone • Low HF radiation applications (single-ended). • ESD protected on all pins QUICK REFERENCE DATASYMBOLPARAMETERSCONDITIONSMIN.TYP.MAX.UNIT VP positive supply voltage range 4.5 − 18 V PO output power TDA7052A RL = 8 Ω; VP = 6 V 1.0 1.1 − W TDA7052AT RL = 16 Ω; VP = 6 V 0.5 0.55 − W Gv maximum total voltage gain 34.5 35.5 36.5 dB φ gain control range 75 80 − dB IP total quiescent current VP = 6 V; RL = ∞ − 7 12 mA THD total harmonic distortion TDA7052A PO = 0.5 W − 0.3 1 % TDA7052AT PO = 0.25 W − 0.3 1 % ORDERING INFORMATIONEXTENDED TYPEPACKAGENUMBERPINSPIN POSITIONMATERIALCODE TDA7052A 8 DIL plastic SOT97(1) TDA7052AT 8 mini-pack plastic SOT96A(2) Notes 1.
