Piezo Amplifier DEC10.1W

with its minimal footprint, solder-pin integrated interface, and low static power consumption, provides a cost-effective solution for static and low-dynamic piezoelectric driving scenarios where space is constrained and direct PCB integration is required. It is particularly suited for embedded instruments, miniaturized equipment, and multi-channel modular systems.

1. Structural Design

● Ultra-Compact Single-Channel Layout: Dimensions of only 32×20×10.5 mm³ and a weight of approximately 16g. Utilizes a pin-pad design supporting surface mounting or plug-in connection, significantly saving installation space.

● Fully Integrated Pin Interface: Unifies power supply, analog input, and high-voltage output through 5-pin solder pins, simplifying external wiring. Supports direct soldering to the user's PCB, enhancing integration level and reliability.

● Passive Heat Dissipation Structure: Relies on PCB copper pour and natural convection for cooling. No additional heat dissipation measures are required during static operation, making it suitable for low-power, high-density integrated environments.

2. Material Properties

● Low-Ripple Output Design: Output ripple is <2 mVRMS under a capacitive load of 1.8 μF, suitable for high-precision piezoelectric systems sensitive to noise.

● Highly Integrated Circuit Technology: Employs compact SMD components and optimized routing to achieve stable signal transmission and power output within a limited volume.

● Broad Temperature Operating Adaptability: Operating temperature range of -20°C to 50°C, compatible with common industrial and laboratory environments.

3. Core Advantages

● Specialized for Static & Low-Dynamic Use: Optimized for steady-state or slow adjustment scenarios, with a power consumption of only 0.2W, maintaining extremely high voltage stability during low-frequency operation.

● High-Voltage Wide-Range Output: Supports 0 to 150V output voltage, compatible with most low-voltage piezoelectric ceramics and nano-positioning stage driving requirements.

● Easy Integration and Soldering: The 5-pin pad design allows direct connection to the user's PCB, eliminating the need for additional connectors, thereby reducing system complexity and cost.

● Current Protection Mechanism: Provides a peak current of 50mA and an average current of 10mA, balancing instantaneous driving capability and continuous safe operation.

4. Typical Applications

● Embedded Piezoelectric Drive Module: Integrated into PCB-level systems such as optical focus adjustment assemblies, micro-valves, and vibration suppression devices.

● Precision Static Positioning: Used for scenarios like microscope stage fine-tuning, static fiber optic alignment, and sensor zero-point calibration.

● Portable Testing Equipment: Integrated into handheld measuring instruments, micro-probe stations, or low-power scientific instruments.

● Low-Voltage Piezoelectric Stack Driving: Suitable for piezoelectric ceramic actuators or stack actuators requiring voltages below 150V.

5. Usage & Support Notes

● Heat Dissipation Advice: No extra heat dissipation is needed for static use. For continuous operation at higher frequencies or under load, it is recommended to assist heat dissipation via PCB copper pour or increased ventilation.

● Output Characteristic Note: The maximum output voltage may slightly decrease as the output current increases. This characteristic limits the maximum output voltage during dynamic use, whereas static use is unaffected.

● Signal Grounding Optimization: The negative terminal of the analog input signal should be connected directly to the root of the GND pin on the PCB to minimize ground noise interference and improve signal integrity.

● Reliability & Support: Typical connection diagrams and soldering guidelines are provided. Supports small-batch customization of pin arrangements or gain adjustments, and can offer integration design references based on user requirements.
