With their incredibly low offset voltage of 45 µV (typical) and low noise, they are perfectly suited for precision filter applications and instrumentation. The low supply current of 500 µA (typical) is critical for portable or densely packed designs. In addition, the rail-to-rail output swing provides greater dynamic range and control than standard video amplifiers. These products operate from single supplies as low as 2.7 V to dual supplies of ±6 V. The fast settling times and wide output swings recommend them for buffers to sampling A/D converters. The output drive of 30 mA (sink and source) is needed for many audio and display applications; more output current can be supplied for limited durations. The OPx62 family is specified over the extended industrial temperature range (–40°C to +125°C). The single OP162 amplifiers are available in 8-lead SOIC, MSOP, and TSSOP packages. The dual OP262 amplifiers are available in 8-lead SOIC and TSSOP packages. The quad OP462 amplifiers are available in 14-lead, narrow-body SOIC and TSSOP packages. 6 –IN B TOP VIEW V– 4 (Not to Scale) 5 +IN B Figure 3. 8-Lead Narrow-Body SOIC (S Suffix) OUT A 1 –IN A 2 8 V+ OUT B –IN B +IN B OP262 TOP VIEW (Not to Scale) 7 6 5 +IN A 3 V– 4 Figure 4. 8-Lead TSSOP (RU Suffix) OUT A 1 –IN A 2 +IN A 3 V+ 4 14 13 OUT D –IN D +IN D OP462 12 TOP VIEW 11 V– (Not to Scale) +IN B 5 10 +IN C –IN B 6 OUT B 7 9 8 –IN C OUT C Figure 5. 14-Lead Narrow-Body SOIC (S Suffix) OUT A 1 –IN A 2 +IN A 3 V+ 4 +IN B 5 –IN B 6 OUT B 7 14 13 OUT D –IN D +IN D V– +IN C –IN C OUT C OP462 TOP VIEW (Not to Scale) 12 11 10 9 8 Figure 6. 14-Lead TSSOP (RU Suffix) Rev.

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. ____________________________ 1 θJA is specified for the worst-case conditions, that is, θJA is specified for a device soldered in circuit board for SOIC, MSOP, and TSSOP packages. ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Rev.
