• OP290: Drop in replacement

    We are having difficulties obtaining this part. Do you have a 'drop-in'
    replacement for this part, with a similarly low input offset voltage, in a 8pin
    DIL package. We are using this amplifier in a battery powered, portable,
  • RE: AD5412 with I and V out on same pin

    Hi,

    The following part would suit your needs.

    The OP290 is a high performance micropower dual op amp that operates from a single supply of +1.6V to +36V or from dual supplies of ±0.8V to ±18V. Input voltage range includes the negative rail allowing…
