Compact Headphone Amplifiers
Headphone Amplifier
Designed for 0.93V Low Voltage Operation
BU7150NUV
No.15102EET01
●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.
●Features
1) Wide battery operation Voltage (0.93V~3.5V, Ta=0~85°C) (1.03V~3.5V, Ta= -40~85°C)
2) BU7150NUV can be selected in single-ended mode for stereo headphone and BTL mode for mono speaker operation
3) Unity-gain stability
4) Click and pop-noise reduction circuit built-in
5) Shutdown mode(Low power mode)
6) High speed turn-on mute mode
7) Thermal shutdown protection circuit
8) Power-on reset circuit not sensed during start-up slew rate of supply voltage
9) Small package (VSON010V3030)
●Applications
Noise-canceling headphone, IC recorder, Mobile phone, PDA, Electronic toys etc..
●Absolute Maximum Ratings (Ta=25℃)

Note 1: If the supply voltage is 0.93V, BU7150NUV does not operate at less than 0°C.
If the supply voltage is more than 1.03V, BU7150NUV operates until -40°C.
(But, it is not the one which guarantees the standard value for electric characteristics.)
Note 2: Ripple in power supply line should not exceed 400mVP-P.(VDD=1.5 V, Ta=25°C )
