AP358SL-13

Overview

The AP358SL-13 is a low power dual operational amplifier from Diodes Incorporated, packaged in SOP-8L. It operates on a single supply voltage ranging from 3V to 32V or dual supplies of ±1.5V to ±16V. Key electrical parameters include a typical input offset voltage of 2mV, an input bias current of 45nA, and a unity gain bandwidth of 1MHz. The device features a large DC voltage gain of 100dB and a supply current drain of 500μA at 5V. It supports rail-to-rail output swing down to ground and includes internal frequency compensation for stability.

Feature Summary

• Internally frequency compensated for unity gain operation
• Input common-mode voltage range includes ground potential
• Output voltage swings to ground with single supply operation
• Temperature compensated unity gain cross frequency

Applications

• Transducer amplifiers
• DC gain blocks
• Single power supply systems replacing dual supplies
• Direct interface electronics for digital +5V systems

Procurement Notes

Verify the package code 'S' corresponds to SOP-8L and suffix '-13' indicates tape and reel packaging. Confirm RoHS compliance and green molding compound status (no Br, Sb). Check datasheet revision DS31007 Rev. 6-2 for latest thermal derating guidelines and absolute maximum ratings before finalizing procurement specifications.

Selection Notes

Select this component when single-supply operation near ground is required without external biasing networks. The low supply current makes it suitable for battery-powered applications. Ensure load capacitance does not exceed stability limits; use resistive isolation for larger capacitive loads. Verify that input voltages do not go negative beyond -0.3V to prevent forward biasing of input diode clamps.

Part Context

Part of the AP358 series of low power dual operational amplifiers designed for wide voltage ranges. The SL variant specifically denotes the SOP-8L lead-free package. This series allows direct operation from standard digital logic supplies, eliminating the need for additional ±15V rails commonly used in conventional op amp circuits.

FAQ

Can the AP358 handle differential input voltages exceeding the supply voltage?

Yes, the differential input voltage may be larger than V+ without damaging the device, as no large input currents result from such conditions.

What is the minimum operating supply voltage?

Amplifier operation is possible down to a minimum supply voltage of 2.3VDC at 25°C, though the rated range starts at 3V.
