Hi Support team 

my customer is looking for close to 500Khz bandwidth AMC1311 

do we have suitable part to support this request?

    Hi Red,

    We do not have an isolated amplifier with a bandwidth greater than 310kHz. 

    It is possible to get a higher bandwidth measurement using an isolated modulator such as the AMC1336 or AMC1306. However, this comes at the expense of resolution. 

    Is the 500kHz bandwidth requirement for safety or a measurement?  It may be an option for the customer to feed the output from an isolated modulator to two different SDFMs, one for high resolution and lower bandwidth, the other for higher bandwidth and lower resolution. 

    Please see this paper for additional information: http://www.ti.com/lit/an/sbaa359a/sbaa359a.pdf
