Data Sheet LOW POWER QUAD OPERATIONAL AMPLIFIERS General Description Features The AS324/324A consist of four independent, high gain and internally frequency compensated operational amplifiers. They are specifically designed to operate from a single power supply. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. Typical applications include transducer amplifiers, DC gain blocks and most conventional operational amplifier circuits. · · Internally Frequency Compensated for Unity Gain Large Voltage Gain: 100dB (Typical) Low Input Bias Current: 20nA (Typical) Low Input Offset Voltage: 2mV (Typical) Low Supply Current: 0.5mA (Typical) Wide Power Supply Voltage Range: Single Supply: 3V to 36V Dual Supplies: ±1.5V to ±18V Input Common Mode Voltage Range Includes Ground Large Output Voltage Swing: 0V to VCC -1.5V · Power Drain Suitable for Battery Operation · · · · · · The AS324/324A series are compatible with industry standard 324. AS324A has more stringent input offset voltage than AS324. The AS324 is available in SOIC-14, DIP-14 and TSSOP-14 packages, AS324A is available in SOIC-14 and DIP-14 packages.
