Product Summary

The STA518 is a monolithic quad half bridge stage in Multipower BCD Technology. The device can be used also as dual bridge or reconfigured, by connecting CONFIG pin to Vdd pin, as single bridge with double current capability. The STA518 is particularly designed to make the output stage of a stereo All-Digital High Efficiency (DDX) amplifier capable to deliver an output power of 24W * 4 channels @ THD = 10% at Vcc 30V on 4W load in single ended configuration.

Parametrics

STA518 absolute maximum ratings: (1)VCC DC Supply Voltage (Pin 4,7,12,15): 40 V; (2)Vmax Maximum Voltage on pins 23 to 32: 5.5 V; (3)Top Operating Temperature Range: -40 to 90℃; (4)Ptot, Power Dissipation (Tcase = 70℃): 21 W; (5)Tstg, Tj, Storage and Junction Temperature: -40 to 150℃.
