Key Parameters

Substitute Part Grouping Explanation

Substitution of the AS358P-G1 is determined by strict equivalence across the following critical parameters:

• Amplifier Configuration: Dual general-purpose operational amplifier with identical circuit count (2 circuits)
• Electrical Performance: Input bias current (20 nA), input offset voltage (2 mV), supply current (700µA per channel), and output current capability (40 mA per channel) must match exactly
• Supply Voltage Range: Operating range from 3 V to 36 V minimum and maximum supply span
• Temperature Rating: Operating temperature range of -40°C to 85°C
• Package Compatibility: 8-DIP through-hole package with 0.300" (7.62mm) pitch
• Moisture Sensitivity: MSL rating of 1 (Unlimited)

The AS358P-E1 qualifies as a direct substitute based on complete electrical and mechanical parameter equivalence. The primary distinction is product status: AS358P-E1 is active production, whereas AS358P-G1 is obsolete.
