[ Product description ]

BU7150NUV is Audio Amplifier designed for Single-cell battery operated audio products (VDD = 0.93 ~ 3.5V, at Ta=0~85°C). BU7150NUV can be selected in single-ended mode for stereo headphone and BTL mode for mono speaker operations. For BU7150NUV at VDD = 1.5V, THD+N = 1%, the output power is 14mW at RL = 16Ω in single-ended mode and the output power is 85mW at RL = 8Ω in BTL mode.
