HIGH VOLTAGE AMPLIFIER

High voltage amplifier converts input voltage to high voltage waveform as it is as shown in fig. These days the demand of high voltage amplifier is growing more and more, and now becoming an indispensable tool for research and development, experiments and integrating to a system for such fields as electronics, physics, biochemical and medical industries. With high voltage technologies Matsusada Precision Inc. manufactures various high voltage amplifiers to meet all requirements from customers.

FOUR-QUADRANT OUTPUT RANGE

High voltage amplifier is generally equipped with the "sink" function for output currents that provides constant voltage operation without regard to the type of load whether it is capacitive or conductive.
As it gives fast response, it is an ideal power supply for applications which require AC output. Matsusada Precision high voltage amplifiers are all bipolar type and can be operated in full four-quadrant area. (I, · II, · III, · IV, and area)

Output range

SLEW RATE

Slew rate | Matsusada Precision

The responsivity of our high speed amplifier is determined with slew rate (SR). The step responsivity of our amplifier is as shown in fig. SR = ΔV/μs In case of output amplitude is smaller the response time become shorter. AMP series reach to greater than SR = 700 V/μs at maximum.

RISE TIME (STEP RESPONSE)

Step response can be indicated with rise time. (fig)
Usually the rise time of amplifier of response (= bandwidth) fc (Hz) is given by a formula below. tr 0.35/fc The fall time tf is equals to tr.
