AFE032: AFE032

Part Number: AFE032
Other Parts Discussed in Thread: AFE031

Hello,

i have used AFE301, but i plan to change the analog front end from AFE301 to AFE032. what are the requests to use AFE032. can i use it instead of AFE301? 

Kind Regards!

Behailu. 

  • Hello Behailu,

    I will look at the internal registers and get back to you on compatibility.

  • Hello Behailu,

    I have looked into the difference between the AFE031 And AFE032 device. The first part that is different is the register address and initialization of the device however, the AFE032 datasheet gives you instructions on how to write the code for the different sequences including initialization. the power opamp on board the AFE032 can output current capability is 1.9A versus the AFE031 at 1.5A. The programmable filter on the AFE032 can be programmed to have a pass-band at higher frequencies (up to 505kHz typical)that the AFE031 device (145kHz typical). This is due to the AFE032 device was developed for ARIB/FCC communication standards for e-metering. Other than that the devices are similar.
