ADA4932-x 2.8V supply operation

Can we use the ADA4932-x in single supply operation with a 2.8V supply and 2 Vp-p output swing?

  • Unfortunately not, this part needs 1V headroom from each rail. This will leave us 0.85V p-p single ended (1.7V differential) at 2.85V supply. However using a rail to rail output differential amplifier such as the AD8139 or the AD8137 will work as long as the other parameters are met.

    A good way to avoid potential problems when designing using our differential amplifiers is to use our Differential Amplifier Calculator (Diffampcalc). This tool helps reduce design time from hours to minutes and helps avoid costly mistakes and ... It's also free to download.
