DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT μ PC835 LOW-POWER, HIGH-STABILITY, LOW-OFFSET VOLTAGE J-FET INPUT DUAL OPERATIONAL AMPLIFIER DESCRIPTION The μ PC835 is the higher version of μ PC832 and 4062, the J-FET input operational amplifiers, in stability and accuracy. The μ PC835 is a J-FET input dual operational amplifier which realizes both low power consumption and high stability, by adopting a high speed PNP transistor of fT = 300 MHz on its output stage. In addition, despite its J-FET input, the μ PC835 realizes low offset voltage characteristics that eclipses conventional general operational amplifiers, by using a resistance trimming system, the proven method for our high accuracy operational amplifier and high accuracy reference voltage. The μ PC835 is ideal for use in measurement instruments and control instruments, which especially requires the stability during capacitive load connections. FEATURES • Input offset voltage ±3 mV MAX. • Slew rate 5.5 V/μ s TYP. • Unity gain frequency 2.8 MHz TYP. • Low power ICC ≤ 2.2 mA MAX. (Reduces circuit currents while maintaining relatively high slew rate and bandwidth) • High stability is secured to capacitive loads (4000 pF, AV = +1) • Internal frequency compensation • Small package The whole size of the package is downsized by 30 to 40% compared with a standard SOP contour, 2 by using a TSSOP (3 x 3 mm body) package ORDERING INFORMATION Part Number μ PC835MN-KAA-E1-AT Note Package Packing Type 8-pin plastic TSSOP (3 x 3) • 12 mm wide embossed taping • Pin 1 at draw-out side • 4000 p/reel μ PC835MN-KAA-E2-AT Note 8-pin plastic TSSOP (3 x 3) • 12 mm wide embossed taping • Pin 1 at reel side • 4000 p/reel Note Pb-free (This product does not contain Pb in the external electrode and other parts.)

Note that reverse connections of the power supply may damage ICs. 2. The input voltage should be allowed to input without damage or destruction. Even during the transition period of supply voltage, power on/off etc., this specification should be kept. The normal operation will establish when the both inputs are within the Common Mode Input Voltage Range of electrical characteristics. 3. This specification is the voltage which should be allowed to supply to the output terminal from external without damage or destructive. Even during the transition period of supply voltage, power on/off etc., this specification should be kept. The output voltage of normal operation will be the Output Voltage Swing of electrical characteristics. 4. This is the value when TA ≤ 59°C during loading a glass epoxy substrate (size: 100 mm x 100 mm, thickness: 1 mm, filling wiring of 15% of the substrate only on the one side of copper foil). When TA > 59°C, conduct a derating in −5.4 mW/°C. The heat resistance between a junction and ambient air under the same condition is Rth(J-A) = 187°C/W. 5. Pay careful attention to the total power dissipation not to exceed the absolute maximum ratings, Note 4. Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any parameter. That is, the absolute maximum ratings are rated values at which the product is on the verge of suffering physical damage, and therefore the product must be used under conditions that ensure that the absolute maximum ratings are not exceeded.

This current flows irrespective of the existence of use. Caution Special attention is required for insulation between pins on a board, since the μ PC835 has a high-input impedance characteristic. 4 Data Sheet G18672EJ1V0DS μ PC835 TYPICAL PERFORMANCE CHARACTERISTICS (TA = 25°C, unless otherwise specified) (Reference value) AV, φ vs. f PT vs. TA (ABSOLUTE MAXIMUM RATING) 180 V± = ±15 V 160 AV − Voltage Gain − dB, φ − Phase Margin − deg.

Data Sheet G18672EJ1V0DS 7 μ PC835 PRECAUTIONS FOR USE O The process of unused circuits If there is an unused circuit, the following connection is recommended. Process example of unused circuits V+ V+ R − + R To potentials within the range of common-mode input voltage (VICM) V V O Power supply to be used (single/dual) Operational amplifiers operate when a given voltage is applied to between V+ and V−. Therefore, they can operate with a single power supply (V− = GND). However, since input/output around the GND is impossible with the single power supply, it is required to pay attention to the common-mode input voltage range and the maximum output voltage when using them. O Ratings of input/output pin voltage When the voltage of input/output pin exceeds the absolute maximum rating, it may cause degradation of characteristics or damages, by a conduction of a parasitic diode within an IC. In addition, when the input pin may be lower than V−, or the output pin may exceed the supply voltage, it is recommended to make a clump circuit by a diode whose forward voltage is low (e.g.: Schottky diode) for protection. O Range of common-mode input voltage When the supply voltage does not meet the condition of electrical characteristics, the range of common-mode input voltage is as follows. VICM (TYP.): V− +3 to V+ (V) (TA = 25°C) During designing, consider variations in characteristics and temperature characteristics for use with allowance. O The maximum output voltage The range of the TYP. value of the maximum output voltage when the supply voltage does not meet the condition of electrical characteristics is as follows: VOm+ (TYP.): V+ −1 (V) (TA = 25°C, RL ≥ 10 kΩ), VOm− (TYP.): V− +1.7 (V) (TA = 25°C, RL ≥ 10 kΩ) During designing, consider variations in characteristics and temperature characteristics for use with allowance. In addition, note that the output voltage range (VOm+ − VOm−) becomes narrow when an the output current increases. O Handling of ICs When stress is added to ICs due to warpage or bending of a board, the characteristic fluctuates due to piezoelectric effect. Therefore, pay attention to warpage or bending of a board. 8 Data Sheet G18672EJ1V0DS μ PC835 PACKAGE DRAWING (Unit : mm) 8-PIN PLASTIC TSSOP (3x3) x2 t S A B 0.15 MAX. detail of lead end 5 8 A3 E θ 4 1 Lp 0.15 MAX.
