AS324/324A LOW POWER QUAD OPERATIONAL AMPLIFIERS Description Pin Assignments The AS324/324A consist of four independent, high gain and internally frequency compensated operational amplifiers. They are specifically (Top View) designed to operate from a single power supply. Operation from split power supplies is also possible and the low power supply current OUTPUT 4 OUTPUT 1 14 1 drain is independent of the magnitude of the power supply voltage. Typical applications include transducer amplifiers, DC gain blocks and INPUT 1- 13 INPUT 4- 2 most conventional operational amplifier circuits. INPUT 1+ 3 12 INPUT 4+ The AS324/324A series are compatible with industry standard 324. 11 GND V 4 CC The AS324A has more stringent input offset voltage than AS324. INPUT 2+ 10 INPUT 3+ 5 The AS324 is available in SO-14 and TSSOP-14 packages, and the AS324A is available in SO-14 package. INPUT 2- 6 9 INPUT 3- 8 OUTPUT 3 OUTPUT 2 7 Features Internally Frequency Compensated for Unity Gain SO-14/TSSOP-14 Large Voltage Gain: 100dB (Typical) Low Input Bias Current: 20nA (Typical) Applications Low Input Offset Voltage: 2mV (Typical) Low Supply Current: 0.5mA (Typical) Battery Charger Wide Power Supply Voltage Range: Cordless Telephone Single Supply: 3V to 36V Switching Power Supply Dual Supplies: 1.5V to 18V Input Common Mode Voltage Range Includes Ground Large Output Voltage Swing: 0V to V -1.5V CC Power Drain Suitable for Battery Operation Lead-Free Packages: SO-14, TSSOP-14 Totally Lead-Free RoHS Compliant (Notes 1 & 2) Lead-Free Packages, Available in Green Molding Compound: SO-14, TSSOP-14 Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free.
