MT-043 TUTORIAL Op Amp Power Supply Rejection Ratio (PSRR) and Supply Voltages POWER SUPPLY REJECTION RATIO (PSRR) If the supply of an op amp changes, its output should not, but it typically does. If a change of X volts in the supply produces an output voltage change of Y volts, then...
Also see page 16 , kSVR Supply-voltage rejection ratio (ΔVCC±/ΔVIO) VCC = ±15 V to ±9 V, VO = 0, RS = 50 Ω +/-9V is fine. Thanks Ronald, In the same light, would we be able to run the 5962-9851503Q2A OP AMP at supply voltages of +9V for +Vs and -15V for ...
A voltage regulator circuit with high accuracy and Power Supply Rejection Ratio (PSRR) is provided. In one embodiment, an op-amp with a voltage reference input to an inverting input has the first output connected to a PMOS transistor's gate. The PMOS transistor's source and drain are each ...

least 10 times the RC time constant of the input RC coupling network (R1/C1 and Rin/Cin) will help insure a reasonable common-mode rejection ratio. With 100-k ohm resistors for RAand RB, practical values of C2 can be kept fairly small as long as the circuit bandwidth is not too low...

This voltage is introduced to provide linear operation in the absence of light falling on the photodiode. Photodiode dark current is approximately 2.5 pA, and contributes virtually no offset error at room temperature. The bias current of the op amp summing junction (negative input) is ...
(R1/C1 and RIN/CIN) will help ensure a reasonable common-mode rejection ratio. With 100 kΩ resistors for RAand RB, practical values of C2 can be kept fairly small as long as the circuit bandwidth is not too low. However, another way to provide the necessary VS/2 biasing for single...
Extending the Usable Power Supply Range of the OPA462 High-Voltage Op Amp Thomas Kuehl, Jonathan McClure, Raymond Zhang Precision Amps ABSTRACT The OPA462 high-voltage (HV), precision op amp is designed for applications using dual supply voltages as high as ±90 V, or a single supply of ...
