PB64 Low Standby Current Power Booster

Apex Microtechnology's 800 V/µs, 1 MHz power bandwidth, PB64 dual channel power booster with 20 mA standby current

Image of Apex Microtechnology's PB64 Low Standby Current Power BoosterApex's PB64 is a high density, low quiescent current, dual channel power booster amplifier designed to perform at slew rates of up to 800 V/µs and provide power bandwidth of 1 MHz for use in high voltage instrumentation, such as pattern generators in flat panel display inspection systems, semiconductor PPS V/I sources, and print head driver electronics in industrial ink jet printers. The PB64 maximizes design flexibility when used in tandem with a general purpose small signal op amp.

The user defined driver and booster combination tailors voltage and current gain and optimizes accuracy, offset, input noise and settling time. The power booster’s dual channel design further extends circuit layout flexibility by allowing each booster channel to be paired with separate small signal amplifiers operating with different parameters. The PB64 can be used without a small signal driver in some applications requiring only an external current limit resistor to function properly.

The PB64A is the A grade version providing enhance performance in the areas of offset voltage and input bias current. The output current per channel also improves to 2 A typical versus a “PEAK” 2 A performance with the base model PB64.
