Dual Power Booster triples performance for semiconductor and flat-panel testers

April 10, 2012 // Nick Flaherty

Cirrus Logic has launched a high speed dual-channel booster amplifier to increase the perfomance of high voltage test equipment.

With a 1,000 V/µs slew rate and 1 MHz of power bandwidth, the PB63 provides three times the performance of the previous booster products. By pairing the device with one or two low-cost op amps, semiconductor and flat-panel test equipment manufacturers can now realize a combination of improved test equipment efficiency and productivity – in a more cost-optimized solution compared to traditional high-voltage amplifiers.
The PB63 features voltage operation of ±20 V to ±75 V and continuous output current drive capability of up to 2 A and is designed to provide both voltage and current gain when paired with a small signal, general purpose operational amplifier. This approach allows the user to optimize the accuracy, off set, input noise and settling time of the composite circuit.
“Through the PB63 booster amplifier, Cirrus Logic delivers the high-voltage performance our customers require, along with a significant speed boost, without having to turn to more expensive amplifier products to get the job done,” said Greg Brennan, vice president and general manager, Cirrus Logic’s Apex Precision Powr® business unit. “Being able to pair the PB63 with an op amp of their choosing enables a flexible, cost-effective approach that allows OEMs to tailor performance for their applications.”
The dual-channel amplifier design of the PB63 provides added value for high density board designs, such as pattern generators in flat panel display inspection systems, deflection circuitry in semiconductor inspection systems, scientific scanning electron microscopes, piezoelectric drivers in printer heads for industrial ink jet printers, and programmable power supplies in semiconductor automated test equipment.
The PB63 is packaged in a 12-pin PowerSIP that affords additional savings on valuable board space, with a footprint that measures less than 1.5 square inches. It is available in sample quantities for evaluation and prototyping, as well as volume production and is priced at $128.94 in 1,000 quantities. An evaluation kit that includes a demo board is available.
