The slew rate is typically 9 V/µs with a supply current of less than 250 µA per amplifier. These unity-gain stable amplifiers have a typical gain bandwidth of 4 MHz. The JFET input stage of the OP282/OP482 ensures that the bias current is typically a few picoamps and is less than 500 pA over the full temperature range. The offset voltage is less than 3 mV for the dual amplifier and less than 4 mV for the quad amplifier. With a wide output swing (within 1.5 V of each supply), low power consumption, and high slew rate, the OP282/OP482 are ideal for battery-powered systems or power-restricted applications. An input common-mode range that includes the positive supply makes the OP282/OP482 an excellent choice for highside signal conditioning. The OP282/OP482 are specified over the extended industrial temperature range. The OP282 is available in the standard 8-lead, narrow SOIC and MSOP packages. The OP482 is available in the PDIP and narrow SOIC packages, as well as a 14-ball WLCSP. 3 V+ 4 +IN B 5 –IN B 6 OUT B 7 – + 13 –IN D + – 12 +IN D OP482 11 V– 10 +IN C – + + – 9 –IN C 8 OUT C Figure 3. 14-Lead PDIP (P-Suffix) [N-14] OUT A 1 14 OUT D –IN A 2 13 –IN D 12 +IN D +IN A 3 V+ 4 OP482 11 V– +IN B 5 10 +IN C –IN B 6 9 –IN C OUT B 7 8 OUT C 00301-004 GENERAL DESCRIPTION 2 +IN A 14 OUT D 00301-003 OUT A Figure 4. 14-Lead, Narrow-Body SOIC (S-Suffix) [R-14] BALL A1 CORNER 2 1 OUT D –IN D A 3 OUT A B –IN A +IN D +IN A C D F +IN B –IN B +IN C –IN C G H V+ V– E OUT C OUT B TOP VIEW (BALL SIDE DOWN) Not to Scale 00301-048 J Figure 5. 14-Ball WLCSP [CB-14-2] Rev.
