GENERAL DESCRIPTION

The ADHV4710 is a high voltage, high power, high

speed operational amplifier optimized for driving up

to ±1A at ±1300V/μs into capacitive and resistive

loads. Combining a high voltage amplifier with low

voltage analog circuitry and an SPI programmable

digital engine, the ADHV4710 is ideally suited for

high voltage applications such as automated test

equipment (ATE), programmable power supplies,

and piezo drive.

The ADHV4710 has extensive configurability for high

voltage signal chains. The amplifier achieves high

slew rate and bandwidth at high gain but can

alternatively be configured in low gain for high

voltage input and output. External

transconductance resistor RSLEW enables stability

under any gain and adjustable slew rate. External

compensation capacitor CCOMP enables the amplifier

output to stably drive unlimited capacitive loads.

A proprietary high voltage BCDMOS process, novel high

voltage architecture, and thermally enhanced package

from Analog Devices Inc. enable this high-performance

amplifier. Fault protection and monitoring are

programmable using SPI. Additional analog features

extend functionality: junction temperature sensor

voltage output and adjustable shutdown delay. The

ADHV4710 operates on high voltage dual supplies up to

±55V, asymmetrical dual supplies, or a single supply of

110V.
