Marshall P-QTDA7293 Integrated Circuit - Marshall, TDA7293 amplifier

Manufacturer Part Number: P-QTDA7293 120V - 100W DMOS audio amplifier with mute/standby. The TDA7293 is a monolithic integrated circuit in Multiwatt15 package, intended for use as audio class AB amplifier in Hi-Fi field applications, such as home stereo, self powered loudspeakers and Topclass TV. Thanks to the wide voltage range and to the high output current capability it is able to supply the highest power into both 4-? and 8-? loads. The built-in muting function with turn-on delay simplifies the remote operation avoiding on-off switching noises. Parallel mode is possible by connecting several devices and using pin11. High output power can be delivered to very low impedance loads, so optimizing the thermal dissipation of the system Measurements and Specs Closed Loop Voltage Gain (GV(closed))29 dB - 31 dB, 30 dB typical Continuous Output Power (PO)75 W min, 80 W typical Current Limiter Threshold (ISC)6.5 A Harmonic Distortion0.005 % typical Input Offset Current (IIO)0.2 μA Input Offset Voltage (VIO)-10 mV to 10 mV Input Resistance (RIN)≥ 100 kΩ Mute Attenuation (ATTmute)60 dB - 80 dB Mute Off Threshold (VMoff)≥ 3.5 V Mute On Threshold (VMon)≤ 1.5 V Open Loop Voltage Gain (GV(open))80 dB Quiescent Current (IQ)≤ 100 mA, 50 mA typical Quiescent Current, standby (Iq st-by)≤ 1 mA, 0.5 mA typical Slew Rate (sr)≥ 5 V/μs, 10 V/μs typical Standby Attenuation (ATTst-by)≥ 70 dB, 90 dB typical Standby Off Threshold (VSToff)≥ 3.5 V Standby On Threshold (VSTon)≤ 1.5 V Supply Range (VS)± 12 V to ± 50 V Supply Voltage Rejection Ratio (svr)75 dB Thermal Protection (Ts)150°C Thermal Resistance, junction to case (RθJC)≤ 1.5°C/W, 1°C/W typical Total Input Noise (eN)1 μV input bias current (IB)≤ 1 μA, 0.3 μA typical Packaging Dimensions0.786 in. × 1 in. × 0.38 in.
