Other Parts Discussed in Thread: TLV2460, OPA2373, OPA2363

looking for General purpose  OpAmp - single supply 1.8 - 3.3, rail-to-rail, with with separate shutdown if possible, low cost,small std package and R2R.

TLV2460/1 looks good exept minimum supply of 2.7v. There is a chance for power the board by 2 AAA batteries. would  like to be able to work till 2.4V

    I assume by "separate shutdowns", you want a dual op-amp.

    Then see the LMV982 - down to 1.8V operation, separate shutdowns, R-R I/O, standard VSSOP package & cheap.

    Also see the OPA2363, OPA2373, OPA2763 and OPA2783.

    Hi Eli,

    The recommended operating conditions table on page 4 of the TLV2460 data sheet lists the supply voltage as 1.8 to 3.6 V. Two AAA batteries providing 2.4 V to the VDD pin should be fine.
