TECNICAL DATA Low Power Dual Operational Amplifier IL38 The IL38 contains two independent high gain operational amplifiers with internal frequency compensation.

1 TECNICAL DATA Low Power Dual Operational Amplifier IL38 The IL38 contains two independent high gain operational amplifiers with internal frequency compensation. The two 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 IL38 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 +DC common to practically any digital system or personal computer application, without requiring an extra 1 power supply just to have the interface electronics you need. The IL38 is a versatile, rugged workhorse with a thousand-and-one 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: 3 ~ 32 (or 1. ~ 16) Input common-mode voltage range includes ground Large output voltage swing: 0 DC to CC -1. DC Power drain suitable for battery operation Low input offset voltage and offset current Differential input voltage range equal to the power supply voltage Possible to exchange the position of Pin9 for Pin1 because of Pin Connection being symmetric (IL38S only) ORDERIN INFORMATION IL38N Plastic IL38D SOIC T A = -40 to 8 C for all packages.

For proper operation, IN and OUT should be constrained to the range ND( IN or OUT ) CC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either ND or CC ). Unused outputs must be left open.
