1 OP0C PRECISION OPERATIONAL AMPLIFIERS Low Noise No External Components Required Replace Chopper Amplifiers at a Lower Cost Wide Input-Voltage Range...0 to ± V Typ Wide Supply-Voltage Range...± V to ± V OFFSET N V CC PACKAGE (TOP VIEW) 5 OFFSET N V CC+ NC Description/ordering information These devices offer low offset and long-term stability by means of a low-noise, chopperless, bipolar-input-transistor amplifier circuit. For most applications, external components are not required for offset nulling and frequency compensation. The true differential input, with a wide input-voltage range and outstanding common-mode rejection, provides maximum flexibility and performance in high-noise environments and in noninverting applications. Low bias currents and extremely high input impedances are maintained over the entire temperature range. The OP0 is unsurpassed for low-noise, high-accuracy amplification of very-low-level signals. These devices are characterized for operation from 0 C to 0 C. TA ORDERING INFORMATION ORDERABLE PACKAGE PART NUMBER 0 C to 0 C PDIP SOIC OP0CP OP0CM Symbol OFFSET N OFFSET N +

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES:. All voltage values, unless otherwise noted, are with respect to the midpoint between VCC+ and VCC.. Differential voltages are at with respect to.. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 5 V, whichever is less.. The output may be shorted to ground or to either power supply.

Note 5: Since long-term drift cannot be measured on the individual devices prior to shipment, this specification is not intended to be a warranty. It is an engineering estimate of the averaged trend line of drift versus time over extended periods after the first thirty days of operation. μv V V V/mV db μv/v mw
