1 KA324 / KA324A / KA2902 Quad Operational Amplifier Features Internally Frequency Compensated for Unity Gain Large DC oltage Gain: 100 db Wide Power Supply Range: KA324 / KA324A: 3 ~ 32 (or ±1.5 ~ 16 ) KA2902: 3 ~ 26 (or ±1.5 ~ 13 ) Input Common Mode oltage Range Includes Ground Large Output oltage Swing: 0 to CC -1.5 Power Drain Suitable for Battery Operation Description November 2014 The KA324 series consist of four independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide voltage range. Operation from split power supplies is also possible so long as the difference between the two supplies is 3 to 32. Application areas include transducer amplifier, DC gain blocks and all the conventional OP Amp circuits which now can be easily implemented in single power supply systems. 14-DIP 1 14-SOP 1 Ordering Information Part Number Operating Temperature Range Top Mark Package Packing Method KA324 KA324 MDIP 14L Rail KA324A KA324A MDIP 14L Rail 0 to +70 C KA324DTF KA324D SOP 14L Tape and Reel KA324ADTF KA324AD SOP 14L Tape and Reel KA2902DTF -40 to +85 C KA2902D SOP 14L Tape and Reel KA324 / KA324A / KA2902 Rev

3 Absolute Maximum Ratings Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. alues are at T A = 25 C unless otherwise noted.

ANTI-COUNTERFEITING POLICY Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, under Sales Support. Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
