SPA1010 10 W Power Amplifier 1 MHz Bandwidth 15 kOhm Input Impedance X1/X10 Gain

The Siglent SPA1010 is a compact, high‑speed power amplifier designed for output enhancement of functiorbitrary waveform generators. It delivers up to 10 W output power into resistive loads, with a bandwidth up to 1 MHz and a high slew rate of ≥ 90 V/µs, making it ideal for driving power components and fast transients. The amplifier features two gain settings (×1 or ×10), allowing input ranges of ±6.5 Vpp or ±1.3 Vpp, respectively, and produces a maximum output of approximately 25.4 Vpp at 1.12 A. Safety features include overcurrent and overtemperature protection, with status LEDs for power, short, and gain selection. Compact and portable, the SPA1010 is widely used in test benches, power electronics evaluation, and signal amplification tasks.
