AP358 LOW POWER DUAL OPERATIONAL AMPLIFIERS AP358 Rev. 4 4 of 15 OCTOBER 2006 www.diodes.com © Diodes Incorporated Electrical Characteristics ( TA = 25 oC, V+ = +5.0V, unless otherwise stated ) (Note 7) Symbol Parameter Conditions Min. Typ. Max. Unit VIO Input Offset Voltage TA = 25 oC, (Note 8) - 2 7 mV IB Input Bias Current IIN(+) or IIN(−), TA = 25°C, VCM = 0V, (Note 9) - 45 250 nA IIO Input Offset Current IIN(+) - IIN(−),VCM = 0V, TA = 25°C - 5 50 nA VICM Input Common-Mode Voltage Range V + = 30V, (Note 10) TA = 25°C 0 - V + -1.5 V V + = 30V - 1 2 IS Supply Current Over Full Temperature Range RL = ∞ on All Op Amps V + = 5V - 0.5 1.2 mA AV Large Signal Voltage Gain V + = 15V, T A = 25°C, RL > 2kΩ, (For VO = 1V to 11V) 25 100 - V/mV CMRR Common-Mode Rejection Ratio TA = 25°C, VCM = 0V to V + -1.5V 65 85 - dB PSRR Power Supply Rejection Ratio V + = 5V to 30V, TA = 25°C 65 100 - dB Amplifier-to-Amplifier Coupling f = 1KHz to 20 KHz, TA = 25°C (Input Referred), (Note 11) - -120 - dB Note: 7. The AP358 temperature specifications are limited to 0°C < TA < +70°C. Note: 8. VO ≅ 1.4V, RS = 0Ω with V + from 5V to 30V; and over the full input common-mode range (0V to V+ -1.5V) at 25°C. Note: 9. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output so no loading change exists on the input lines. Note: 10. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (at 25°C). The upper end of the common-mode voltage range is V + -1.5V (at 25°C), but either or both inputs can go to +32V without damage, independent of the magnitude of V +. Note: 11. Due to 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. |
