Apex Microtechnology, PB64 Low Standby Current Power Booster

PB64 Low Standby Current Power Booster

800V/µs, 1MHz Power Bandwidth, Dual Channel Power Booster with 20mA Standby Current

The PB64 is a high density, low quiescent current, dual channel power booster amplifier designed to perform at slew rates of up to 800V/µs and provide power bandwidth of 1MHz 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 2A typical versus a “PEAK” 2A performance with the base model PB64.
