1 Low Power Quad Operational Amplifier Wide gain bandwidth: 1.3MHz Input common-mode voltage range includes ground Large voltage gain: 1dB Very low supply current per amp: 375µA Low input bias current: 2nA Low input offset current: 2nA Wide power supply range: Single supply: +3V to +3V Dual supplies: ±1.5V to ±15V Description This circuit consists of four independent, high gain, internally frequency compensated operational amplifiers designed especially for automotive and industrial control systems. It operates from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.

Short-circuit from the output to V cc can cause excessive heating and eventual destruction. The maximum + output current is approximately 2mA, independent of the magnitude of V cc 2. Pd is calculated with T amb = +25 C, T j = +15 C and R thja = 8 C/W for DIP14 package R thja = 15 C/W for SO-14 package R thja = 175 C/W for TSSOP14 package 3. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistor becoming forward biased and thereby acting as input diodes clamps. In addition to this diode action, there is also NPN parasitic action on the IC chip. This transistor action can cause the output voltages of the op-amps to go to the V CC voltage level (or to ground for a large overdrive) for the time duration than an input is driven negative. This is not destructive and normal output will set up again for input voltage higher than -.3V. 4. Human body model, 1pF discharged through a 1.5kΩ resistor into pin of device. 5. Machine model ESD, a 2pF cap is charged to the specified voltage, then discharged directly into the IC with no external series resistor (internal resistor < 5Ω), into pin to pin of device. 2/14

V O = 1.4V, R S = Ω, 5V < V + CC < 3V, V < V ic < V + CC - 1.5V. 2. The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the output, so no loading charge change exists on the input lines. 3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more + than.3v. The upper end of the common-mode voltage range is V CC 1.5V, but either or both inputs can go to +32V without damage. 4. Due to the proximity of external components insure that coupling is not originating via stray capacitance between these external parts. This typically can be detected as this type of capacitance increases at higher frequencies. mv V/µs MHz % 5/14
