LM1972: Alternatives with 0.2 dB stepping

Daniel Waleniak

Part Number: LM1972

Dear Team,

I have a quick question regarding LM1972 alternatives. My customer is interested in a part with 0.2 dB stepping. Do you have any recommendations? My customer uses the part to calibrate sensors with PGA450.

Many thanks,

Daniel

Hello Daniel,

Unfortunately all the Volume Control ICs we offer as found in the link below only go down to .5dB stepping.
