LA75A

Product catalog summary

Product Overview: The LA75A is a linear amplifier designed for piezoelectric actuators, capable of driving up to three channels. It is suitable for high-accuracy positioning applications.

Key Features: The amplifier offers a continuous output of 90 mA and an optional peak output of 300 mA. It operates within an output voltage range of [-20 V; 150 V] and features low noise with an SNR of 85 dB and THD of 0.1%. It includes options for push-pull configuration and is fully protected against overcurrent, overtemperature, and overvoltage.

Specifications:

General: Functions as a driver for piezoelectric actuators with 1 to 3 channels.
Input: Control input voltage ranges from -1 to +7.5 V with an impedance of 10 kΩ.
Output: Voltage range is -20 to +150 V, with a continuous peak output current of ±90 mA and a transient peak output current of ±300 mA.
Power Amplifier: Peak output power is 45 W.
Gain: Gain is 20 V/V with a gain error of ±1% and a linearity error of 0.01%.

Dynamic Performance: The small signal bandwidth is 30 kHz, and the power bandwidth is detailed in a chart. The THD is 0.1%, and the signal-to-noise ratio is 85 dB.

Miscellaneous: The device weighs 1 kg, with dimensions of 10F wide and 3U high. It requires a warm-up time of 15 minutes and operates within a temperature range of 0 to 40 °C.

Interfaces: Includes BNC type order input, LEMO EPL-00-250 piezo actuator output, and a 10-turn screw potentiometer for DC offset.

Included Accessories: Comes with a piezo actuator cable (Coax 1.5m) with Lemo connector and 2x banana 1mm plug.

Options: Offers push-pull capability, specific output connectors, and controllers for position loops. Custom piezo cable lengths and adapters are available upon request.
