GENERAL DESCRIPTION The OP262-EP is a low power, precision op amp that features a rail-to-rail output and a 15 MHz bandwidth. With its low offset voltage of 45 µV (typical) and low noise, it is well suited for precision filter and control applications. This product operates from a single supply as low as 2.7 V or from dual supplies up to ±6 V. The OP262-EP is specified over the military temperature range (−55°C to +125°C) and is available in an 8-lead SOIC_N package. Additional applications information is available in the OP162/OP262/OP462 data sheet.
APPLICATIONS Portable instrumentation Sampling ADC amplifiers Precision filters

Long-term offset voltage is guaranteed by a 1000 hour life test performed on three independent lots at 125°C, with an LTPD of 1.3. Offset voltage drift is the average of the −55°C to +25°C delta and the +25°C to +125°C delta.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Table 5. Package Type 8-Lead SOIC (R) 1
For supply voltages greater than 6 V, the input voltage is limited to less than or equal to the supply voltage. For differential input voltages greater than 0.6 V, the input current should be limited to less than 5 mA to prevent degradation or destruction of the input devices.
