Product details

The BU7150NUV-E2: The BU7150NUV-: The ROHM BU7150NUV- is a low-voltage Class AB audio amplifier that can drive either a single 8-ohm speaker at 85 mW or a stereo 16-ohm headphone pair at 14 mW per channel. The part includes depop circuitry to suppress turn-on clicks, plus short-circuit and thermal protection, so it can survive a miswired output in a field-repair scenario.

The 85 mW into 8 ohms is enough for a small internal speaker or earpiece; the 14 mW into 16 ohms suits standard headphone outputs. If your design needs more than 100 mW or a bridged load, this part is not the right choice — step up to a Class D like the BD5426EFS- (10 W into 4 ohms). The sub-1 V minimum supply (0.93 V) means the amp stays alive as a Li-ion cell discharges below 3.0 V, which extends usable runtime in battery gear. No external charge pump or DC-DC is needed.

The BU7150NUV- comes in a 10-VFDFN with exposed pad (VSON010V3030). The package is surface-mount only; no socket option, so plan for reflow or hot-air rework.

Frequently asked questions

What are alternatives or equivalents to BU7150NUV-?

The closest functional peer is the BH3547F-, also a Class AB stereo headphone amplifier, but it runs on a 4.5 V supply and lacks the sub-1 V capability of the BU7150NUV-. For higher power, the BD5426EFS- is a Class D amplifier delivering 10 W, but it requires a 10 V supply and external output filters. Neither is a drop-in replacement — the BU7150NUV- is unique for its 0.93 V minimum supply and integrated depop.
