ONET1191P Limiting Amplifier Output

Other Parts Discussed in Thread: ONET1191P, ONET1151M

Hi,

I'm currently using the ONET1191P Limiting Amplifier with the schematics as shown below.

With a 200mV differential input, I get about 650mV to 680mV differential output, which is close to typical value of 700mV as specified in the specsheet.

My question is, the specsheet specifies a maximum output of 900mV. Is there a specific method to achieve this output? Lets just say that the 200mV difference is significant for my application. 

Thanks,

Nasri

  • Nasri,

    The 900mVpp maximum takes into account variation over voltage, temperature and process corners. Therefore, it is referring to the maximum possible that may be found in a very large distribution of parts. It is not a value that is typically within a normal distribution of parts.

    If you have an I2C bus available then the ONET1151M can provide higher output voltage (3Vpp differential) into a 100ohm differential load. You can control the output amplitude through the I2C or with an analog voltage.

    Regards,

    Alex.
