Key Features
- Class G amplifier topology delivering 14 V peak-to-peak output swing for high SPL from ceramic speakers
- 2.4 W nominal output power from a compact 28-pin 4×4 mm LFCSP footprint
- Single-channel design optimized for ceramic (piezoelectric) speaker loads in portable devices
- Efficient Class G supply modulation reduces heat generation and extends battery life
- Introduced 2007 with JESD-609 e3 lead-free packaging for consumer RoHS compliance
Applications
The MAX9788ETI+ is designed for driving ceramic and piezoelectric speakers in smartphones, feature phones, and compact consumer electronics where loud audio output is needed from a small PCB footprint. Its Class G topology dynamically switches supply rails to match signal amplitude, reducing average power dissipation compared to a fixed-rail Class AB amplifier. This makes it well suited for battery-powered portable devices such as handheld GPS units, digital cameras, and personal media players where audio efficiency directly impacts battery runtime.

Frequently Asked Questions
What output voltage swing does the MAX9788ETI+ provide for a ceramic speaker, and why does that matter?
The MAX9788ETI+ generates up to 14 V peak-to-peak across its output. Ceramic speakers have a capacitive impedance that requires high voltage drive to produce sufficient acoustic displacement; a 14 V peak-to-peak swing provides the necessary excursion for audible volume levels from a small piezoelectric element at 2.4 W nominal power.
How does the Class G architecture of the MAX9788ETI+ improve power efficiency over a conventional Class AB speaker driver?
Class G amplifiers use multiple supply voltage rails and switch to the higher rail only when signal peaks require it. For the MAX9788ETI+, this means most of the time the amplifier operates from a lower supply voltage, reducing the average voltage drop across the output stage and lowering dissipation, which is critical for portable devices with limited battery capacity.
What PCB footprint does the MAX9788ETI+ occupy, and is it compatible with standard pick-and-place assembly?
The MAX9788ETI+ is housed in a 28-pin LFCSP (QFN-style) package measuring 4×4×0.75 mm with an exposed pad. This compact footprint is fully compatible with standard automated pick-and-place and solder-reflow assembly, and the 0.5 mm pin pitch allows placement on typical high-density consumer PCBs.
Is the MAX9788ETI+ still in production, and what is the lifecycle risk for a new design?
The MAX9788ETI+ was introduced in January 2007 and carries a YTEOL (years to end of life) indicator of 10 years from its database entry. Designers starting new projects should verify the current lifecycle status with Analog Devices or authorized distributors and consider the long-term availability of this single-channel 2.4 W Class G device before committing to it for a production design.
