AS358/358A/358B LOW POWER DUAL OPERATIONAL AMPLIFIERS Description Pin Assignments The AS358/358A/358B consists of two independent, high gain and internally frequency compensated operational amplifiers, they are (Top View) specifically designed to operate from a single power supply. OUTPUT 1 1 8 VCC Operation from split power supply is also possible and the low power supply current drain is independent of the magnitude of the power OUTPUT 2 INPUT 1- 2 7 supply voltages. Typical applications include transducer amplifiers, INPUT 1+ 3 6 INPUT 2- DC gain blocks and most conventional operational amplifier circuits. INPUT 2+ GND 4 5 The AS358/358A/358B series is compatible with industry standard (SO-8/TSSOP-8/MSOP-8) 358. The AS358A has more stringent input offset voltage than the AS358. (Top View) The AS358 is available in PDIP-8, TDIP-8, SO-8, TSSOP-8 and MSOP-8 packages, the AS358A is available in PDIP-8 and SO-8 OUTPUT 1 1 8 VCC packages and AS358B is available in TSSOP-8 package. INPUT 1- 2 OUTPUT 2 7 INPUT 1+ 3 Features 6 INPUT 2- Internally Frequency Compensated for Unity Gain GND 4 5 INPUT 2+ Large Voltage Gain: 100dB (Typical) (PDIP-8/TDIP-8) Low Input Bias Current: 20nA (Typical) Low Input Offset Voltage: 2mV (Typical) Low Supply Current: 0.5mA (Typical) Applications Wide Power Supply Voltage: Single Supply: 3V to 36V Battery Charger Dual Supplies: 1.5V to 18V Cordless Telephone Input Common Mode Voltage Range Includes Ground Switching Power Supply Large Output Voltage Swing: 0V to V -1.5V CC Lead-Free Packages: SO-8, PDIP-8 and TSSOP-8 Totally Lead-Free RoHS Compliant (Notes 1 & 2) Lead-Free Packages, Available in Green Molding Compound: SO-8, PDIP-8, TDIP-8, TSSOP-8 and MSOP-8 Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free.
