F10AD
Two channels, fixed ×10 gain, ±100 V wideband high-voltage linear amplifier
The F10AD is two F10A amplifiers in one enclosure: two independent channels, each with fixed ×10 gain, ±100 V output, 185 mA and about 30 W. The reason to buy a dual-channel unit is usually not price but rack space and wiring. The two channels share one supply and one ground, so there is no ground potential difference between them, a real technical difference wherever two signals must stay tightly aligned. It suits XY piezo stages, differential drive of paired elements, and any setup that needs two outputs from one common source.
Overview
Two single-channel amplifiers side by side and one dual-channel instrument rarely behave the same. Two separate units each have their own supply and ground, the chassis can sit at slightly different potentials, and the common-mode relationship between the two outputs is uncontrolled. Where two signals must line up precisely, in XY positioning, differential drive or synchronized dual-element tests, that uncertainty shows up directly in the result. The two F10AD channels share one supply and one ground plane, so the common-mode relationship is fixed. Each channel matches the F10A: ×10 gain, ±100 V bipolar, 185 mA output current, about 30 W, DC to 1 MHz. The channels are controlled independently, so the unit can also serve as two unrelated amplifiers that happen to share a box and a supply, which is practical where rack space is tight. Sizing is the same exercise as for the single-channel model: work out the capacitive load current at your highest operating frequency, and account for total power when both channels run at full swing at once.

Features
Shared supply and ground
The common-mode relationship between the two outputs is fixed; XY positioning and differential drive are not disturbed by chassis potential differences.
Each channel equals an F10A
×10 gain, ±100 V, 185 mA, about 30 W; nothing is derated for the sake of integration.
Independent channel control
When needed it works as two unrelated amplifiers.
Half the rack space
Two channels, one enclosure, one supply: less cabling and fewer rack units.
Watch total power
Include both channels at full swing in your supply and cooling budget.
Who uses it
Two-axis stages in research institutes, characterization stations at component makers, and display and MEMS development lines are where this unit usually lands.
Typical applications
Piezo drive
Piezo actuator positioning and vibration control
Researchers use the F10AD to raise a ±10 V function generator waveform to ±100 V for piezo actuators doing nanometer positioning or active vibration suppression. The shared-ground dual-channel layout lets one instrument drive X and Y together, which is what a scanning probe microscope or an optical table isolation system needs for coordinated two-axis motion.
MEMS characterization
Electrostatic actuation and functional test of MEMS devices
In MEMS development labs, engineers apply bipolar high-voltage excitation from the F10AD to comb drives or micromirrors and record pull-in voltage and displacement linearity. The 1 MHz bandwidth and 400 V/µs slew rate reproduce the waveform faithfully across a wide sweep, so distortion does not creep into the measurement.
Optoelectronic testing
Electrical evaluation of liquid-crystal and OLED devices
Display makers and research groups drive LC cells and OLED samples with accurate AC high voltage from the F10AD to measure threshold voltage, C-V curves and emission efficiency. The amplifier's linearity keeps harmonic distortion out of the test signal, so the data reflects the device rather than the driver.
