Overview

Pendulum Instruments High Voltage Linear Amplifiers are general-purpose broadband linear amplifiers designed for test and measurement applications where a signal source is too weak for the intended task. Covering a frequency range from DC up to the MHz region, these amplifiers deliver ultra-linear performance with either fixed or variable gain and support both bipolar and unipolar output modes.

They are widely used in research institutes, R&D laboratories, and component manufacturing industries for applications such as driving piezo actuators, MEMS devices, OLEDs, liquid crystals, and other precision loads.

All models are designed to drive resistive and small capacitive loads and include built-in current limiting protection to withstand accidental short circuits, ensuring reliable and safe operation.

Key Features

• Ultra-linear amplification across a wide voltage range
• Broadband operation from DC up to MHz frequencies
• High output power with fast slew rates (up to 500 V/μs)
• Low output impedance (down to 0.1 Ω)
• Flexible configurations for different performance and budget requirements

Product Configurations

Pendulum Instruments offers two main amplifier configurations to match different application needs:

Single-Channel High Voltage Linear Amplifiers

Single-channel amplifiers provide a straightforward and versatile solution for applications requiring one high-voltage output. They are available in multiple series optimized for cost, voltage range, power, and speed, covering output voltages from tens up to hundreds of volts and bandwidths up to several MHz.

Dual-Channel High Voltage Linear Amplifiers

Dual-channel amplifiers integrate two amplifiers in a single unit, enabling synchronized operation or advanced signal configurations. In addition to independent dual outputs, certain models include a phase inverter that allows combining channels to effectively double the output voltage amplitude.

Choose the Right Solution

Whether your application requires a compact single-channel solution or a flexible dual-channel system with enhanced output capabilities, Pendulum Instruments provides a wide range of models to meet your exact performance requirements.
