Alfa Rpar - AS401 - Hi-End Audio Operational Amplifier
Product information "Alfa Rpar - AS401 - Hi-End Audio Operational Amplifier"
AS401 / AS401A is bipolar-input Hi-End audio operational amplifier and provide ultra-low THD+Noise level - 130dB (1Khz) and -110dB (40kHz) for RL= 600 Ohm & CL=100 pF. Amplifier drives a 32 Ohm load at 10 mW and 600 Ohm load at 70 mW. AS401 is unity-gain stable and provides excellent dynamic behavior over a wide range gain and load conditions at a wide supply range of ±4,5 to ±18 V.
AS401A benefits from additional balance inputs (offset trimming) and additional pin for case shielding.
AS401 / AS401A is a hybrid module with DIP8 footprint.
Features:
• Hi-End sound quality
• less then 2 nV/√Hz low input voltage noise
• ultra-low total harmonic distortion+ noise (RL = 600 Ohm CL = 330 pF):
0,00015 % at 20 kHz
0,00036 % at 40 kHz
• unity-gain stable at RL=600 Ohm CL=1000 pF
• phase margin at G=+1 & RL = 600 Ohm without external correction:
125° at CL=100 pF
60° at CL=330 pF
• slew rate G=+1 30 V/μS & RL = 600 Ohm CL = 330 pF
• low input offset voltage 250μV (max)
• bandwidth > 35MHz
• wide supply range +9 V to +36 V (±4,5 V -±18 V)
• input current < 1μA
• linear output stage class A
• low small-signal overshoot with capacitive load (100mV output step):
8% RL=600 Ohm, RSL=0 Ohm, CL=100 pF;
10% RL=600 Ohm, RSL=0 Ohm, CL=250 pF;
30% RL=600 Ohm, RSL=0 Ohm, CL=1000 pF;
15% RL=600 Ohm, RSL=25 Ohm, CL=1000 pF
• no phase reversal
• peak-to-peak output voltage swing 32V typ. with Vcc= ±18V and Rl=600 Ohm

Safety Instructions for Electronic and Mechanical Components
Intended Use:
• Electronic components, including potentiometers, knobs, switches, connectors, resistors, capacitors or integrated circuits (ICs), are designed for use in electronic circuits and devices.
• Use these components only for their intended purposes in electrical and electronic applications, according to their specified voltage, current, and environmental conditions.
• Any use outside the intended applications may result in malfunction or safety risks.
Handling and Installation
Installation:
• Handle electronic components with appropriate tools, such as tweezers, to avoid physical damage or exposure to electric shock.
• Ensure that the components are installed in the correct orientation and according to manufacturer specifications to avoid malfunction or damage to the circuit.
Storage:
• Store components in a dry, cool, and static-free environment to avoid damage from moisture, extreme temperatures, or electrostatic discharge (ESD).
• Avoid direct exposure to sunlight, which could affect component stability and performance.
Protection from Static Electricity:
• Use antistatic equipment (e.g., wrist straps, ESD mats) when handling electronic components to prevent electrostatic discharge, which can damage sensitive devices like ICs.
Compatibility:
• Make sure electronic components are compatible with the circuit in terms of voltage, current, and other technical specifications.
Warnings
Electrical Shock Hazard:
• Some components can retain charge even when disconnected. Use appropriate tools and take precautions when handling components to minimize the risk of electric shock.
Burn or Fire Risk:
• Overloading or misusing electronic components may result in overheating, which could lead to burning or fires. Ensure that components are used within their specified voltage and current ratings.
Danger from Misuse:
• Incorrect handling or use outside specified limits can damage the components or affect the performance and functionality of connected devices. Only use components within their specified tolerances and conditions.
Choking Hazard:
• Small electronic components can pose a choking hazard if swallowed. Keep components out of reach of children.
