SL324 Low Power Quad Operational Amplifier The SL324 contains four independent high gain operational amplifiers with internal frequency compensation. The four op-amps operate over a wide voltage range from a single power supply. Also use a split power supply. The device has low power supply current drain, regardless of the power supply voltage. The low power drain also makes the SL324 a good choice for battery operation. When your project calls for a traditional op-amp function, now you can streamline your design with a simple single power supply. Use ordinary +5VDC common to practically any digital system or personal computer application, without requiring an extra 15V power supply just to have the interface electronics you need. The SL324 is a versatile, rugged workhorse with a thousand-andone uses, from amplifying signals from a variety of transducers to dc gain blocks, or any op-amp function. The attached pages offer some recipes that will have your project cooking in no time. • Internally frequency compensated for unity gain • Large DC voltage gain: 100dB • Wide power supply range: 3V ~ 32V (or ±1.5V ~ ±16V) • Input common-mode voltage range includes ground • Large output voltage swing: 0V DC to VCC-1.5V DC • Power drain suitable for battery operation • Low input offset voltage and offset current • Differential input voltage range equal to the power supply voltage LOGIC DIAGRAM PIN 4 = VCC PIN 11= GND SLS System Logic Semiconductor ORDERING INFORMATION SL324N Plastic SL324D SOIC TA = 0° to 70° C for all packages.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.
