What are the key features of HPA00910YZFR?
- Selectable gain range from -28 dB to +30 dB in 1 dB steps via digital control, eliminating external gain-setting resistors and enabling software-defined volume control
- 3 W Class-D output with 95 dB signal-to-noise ratio and 20 kHz audio bandwidth, delivering high-fidelity amplification in a 9-ball BGA package
- High-efficiency Class-D switching topology significantly reduces heat generation compared to Class-AB amplifiers, enabling passive cooling in compact portable speaker designs
What is HPA00910YZFR used for?
HPA00910YZFR is well suited for portable Bluetooth speakers, tablet audio output stages, and smart home devices where a 3 W mono speaker must be driven efficiently from a 3.7 V to 5 V battery supply. Its digitally programmable gain from -28 dB to +30 dB allows the host DSP or MCU to implement precise software volume control over the full audio range without mechanical potentiometers. The compact BGA footprint and high efficiency reduce both board area and thermal management requirements in slim form-factor consumer electronics.

Frequently Asked Questions
What gain range does HPA00910YZFR offer and how is the gain set in a system design?
HPA00910YZFR provides a selectable gain range from -28 dB to +30 dB in 1 dB steps, giving 59 discrete gain levels. The gain is set via a digital control interface, eliminating the need for external resistor-divider networks that drift with temperature. This allows a microcontroller or DSP to implement precise digital volume control across the full range, suitable for smart speakers and tablets where dynamic range adjustment is controlled by application software.
How does the Class-D topology of HPA00910YZFR improve efficiency compared to a Class-AB amplifier at 3 W output?
Class-D amplifiers like HPA00910YZFR switch the output transistors between fully-on and fully-off states, achieving typical efficiency above 85% at rated output versus 50% to 78% for Class-AB designs at 3 W into an 8 ohm load. This means HPA00910YZFR dissipates less than 0.5 W as heat when delivering 3 W of audio power, compared to over 1 W for a comparable Class-AB device, allowing passive cooling and extended battery runtime in portable designs.
What audio bandwidth and SNR specification does HPA00910YZFR achieve and how does that meet consumer audio standards?
HPA00910YZFR delivers a nominal 20 kHz audio bandwidth covering the full human hearing range of 20 Hz to 20 kHz, with a 95 dB signal-to-noise ratio. A 95 dB SNR exceeds the CD audio standard of 90 dB and ensures that background noise is inaudible on typical consumer speakers with 85 dB sensitivity, providing distortion-free reproduction of music and voice at all volume levels within the 3 W output power envelope.
For a portable speaker design, what is the BGA package footprint of HPA00910YZFR and what does that mean for PCB routing?
HPA00910YZFR uses a 9-ball BGA package with a very small body area, typically under 2 mm x 2 mm, which consumes minimal PCB real estate in compact speaker modules and tablets. BGA packages require solder-ball reflow placement and may need blind or through vias for signal routing beneath the device, but the small footprint and short lead inductances improve high-frequency switching performance compared to leaded SOIC packages, reducing EMI on the Class-D output stage.
