Other Parts Discussed in Thread: REF3112 Hi,
we have a REF3112AI on our Micro Controller Board. Some boards show a oszillating output voltage at Vout (kind of saw tooth, about 10kHz); measured directly an C102. Decreasing the value to 2.2µF (or removing…
Other Parts Discussed in Thread: REF3112 HI,
I wish to use the REF3112 device as a voltage reference for the ADC on my 7 Series Xilinx FPGA. I have chosen this as it is part of the recommended circuit from Xilinx in their "XADC User Guide" document (UG480…

My customer would like to know how the device…
Denny,
Since the close-loop output impedance, Rout, of an op amps is a function of the open-loop output impedance, Ro, and a loop gain ( ), it is very low (Zout<<1ohm); thus, any op amp in a buffer configuration will have a low enough impedance and can…
Hello Jason,
I will need to double check the transistor count and our policy for disclosure of such information.
The thermal resistance for the device is provided on table 7.4 of the REF3112 datasheet.
Best regards,
Jose
Other Parts Discussed in Thread: REF3112 , INA155 My input voltage range is from 0 to 200mV. The signal power supply is 5V. In order to avoid the rail-to rail effect, I will a REF3112 to generate 1.25V reference to the REF Pin of INA155, In theory, the…
Hello,
Thank Collin very much for giving very useful reply and details of this mic amplification.
I tried REF3112 with a 4.7uF cap at its output but the oscilloscope shows noisy(~40mV grass-like noise) at the amplifier output (total gain of the two-stage…
