STMicroelectronics TDA7851F
The TDA7851F is a breakthrough MOSFET technology class AB audio power amplifier, deFEATURES
● Multipower BCD technology● High output power capability: – 4 x 48 W/4 Ω max. – 4 x 28 W/4 Ω @ 14.4 V, 1 kHz, 10% – 4 x 72 W/2 Ω max.
● MOSFET output power stage
● Excellent 2 Ω driving capability
● Hi-Fi class distortion
● Low output noise
● Standby function
● Mute function
● Automute at min. supply voltage detection
● Low external component count: – Internally fixed gain (26 dB) – No external compensation – No bootstrap capacitors
● Output DC offset detector
● Protections: – Output short circuit to GND, to Vs, across the load – Very inductive loads – Overrating chip temperature with soft thermal limiter – Load dump voltage – Fortuitous open GND – Reversed battery – ESD
