STA515W 40 V, 3 A, quad power half bridge Datasheet - production data Description The STA515W is a monolithic quad half-bridge stage in Multipower BCD Technology. The device can be used as a dual bridge or reconfigured, by connecting pin CONFIG to pins VDD, as a single bridge with double-current capability. The device is designed, particularly, to be the output stage of a stereo all-digital high-efficiency amplifier. It is capable of delivering 10 W x PowerSO36 package 4 channels into 4 loads with 10% THD at with exposed pad up V = 18 V in single-ended configuration. CC It can also deliver 20 W + 20 W into 8 loads with 10% THD at V = 18 V in BTL configuration CC or, in single parallel BTL configuration, 40 W into Features a 8 load with 10% THD at V = 26 V. CC Multipower BCD technology The input pins have a threshold proportional to Low input/output pulse width distortion the voltage on pin V .
