Multi-Channel Amplifier outputs high voltages.

Press Release Summary:

Dual Channel MA01 delivers up to 330 V, at peak output currents of 120 mA per channel, for loads such as MEMS-based optical switching, piezo positioning systems, ink jet printers, electrostatic deflection and push-pull applications. Precision, monolithic IC provides power bandwidth of 26 Khz at full output voltage. Each channel can operate independently or both channels can be bridged for 660 V p-p output with only slight reduction in total output current.

Original Press Release:

Apex Extends Its High Voltage Multi-Channel Amplifier Family With The Dual Channel MA01 That Delivers Up To 330V At Peak Output Currents Of 120mA Per Channel With No Second Breakdown Into A Wide Variety Of Loads

TUCSON, AZ -- Apex Microtechnology has long been recognized as the industry leader in high voltage and high current power operational amplifiers for applications in the industrial controls, ATE, aerospace, medical and military markets. Apex has now applied that expertise to a growing need in the industrial controls market for high voltage, low quiescent current multi-channel amplifiers, or multi-channel ICs, to drive a wide range of loads such as:
- MEMS-based optical switching
- Piezo positioning systems
- Ink jet printers/electrostatic deflection
- Push-pull applications

The new Apex MA01 is a dual channel precision monolithic high voltage IC solution in an industry standard PSOP package. With a foot print measuring less than 0.5" square, the MA01 drastically reduces the board space requirements in applications where multiple independent loads must each be precisely controlled.

The MA01 features high voltage operation up to 350V and output voltage up to 330V per channel with no second breakdown. It also addresses a key requirement for low quiescent current with less than 2 mA per channel. Power bandwidth is 26 Khz at full output voltage. Each channel can operate independently or both channels can be bridged for 660V p-p output with only a slight reduction in total output current as defined by SOA curves.
