APEX ~ MP106 and MP204 ~ Power Amplifiers for Driving Dynamic Capacitive Loads

The MP106 is a high output power amplifier optimized for producing negative output voltages.

The MP204 is a four-channel power amplifier optimized for 7.5A PEAK output current per channel.

Both are good choices for inkjet printer drive circuits.

 

MP106

The MP106 is a high output power amplifier optimized for driving negative voltages. Rated with a 0 to 540nF drive capability, the MP106 is tailored for dynamically changing loads, such as capacitive loads used in piezo devices for inkjet printing applications, such as Dimatix "Samba" or similar heads. This amplifier is an open frame product design featuring a small footprint measuring just 73.4mm x 41.4mm and capable of up to 130W of internal power dissipation.
