It is specifically designed for professional audio applications and fields that require low noise, low distortion, and high linearity non-staining performance. The noise is below 500nv/rms 20KHz, and the maximum output current can reach 80mA. The current structure adopts multiple pairs of HIFI low-noise transistors and low error mount transistors, paired with multiple precision transistors. The overall sound quality is wide and full, with a grand scene and distinct layers. The mid frequency brightness is clear, the density is high, and the low frequency is deep and elastic. High performance temperature stable power supply current source is used, which allows bias to remain locked at the optimal operating point regardless of power supply voltage or temperature. Specification:The OPS200 Dual operational amplifier can directly replace chips such as NE5532, OPA2604, OP275, LM49720, etc. Application: Low impedance line amplifier and driver Active filters and equalizers Sum/Mixing Amplifier High performance microphone preamplifier High performance A/D or D/A front-end preamplifier High current buffer amplifier High performance D/A I-V converter Output Current: 60mA Working Voltage: 5V-18V Noise Density: Less than 500 nv RMS Distortion Factor: 0.0002% Conversion Rate: 20V/s Color: As Shown Material: PCB Package Contents: 1 x Operational Amplifier Module Only the above package content, other products are not included.
