LALD-400/500/800/1500 Series Low Drift Linear Amplifiers
The LALD (linear amplifier, low drift) Linear Servo Amplifiers are designed for high precision applications which require ultra-low current drift, in the range of micro amps per degree C. Furthermore, Varedan’s proprietary circuitry provides gain switching to allow very accurate low-level current (<500mA) control. This design is inherently balanced and requires no extra setup or adjustment for operation. These high power linear amplifiers are well suited to drive loads such as brushless and brush servo motors or voice coils. Our designs incorporate class AB linear output stages for true linear output.
The design of these amplifiers includes an onboard high-speed DSP that monitors all key system functions in real time, and provides protection for the output bridge by limiting power to a “Safe Operating Area”. An intelligent user interface allows setup and storage of all system parameters via the serial interface. Non-volatile memory provides storage of the parameters during power off conditions.
