Well John, couple of easy comments and cautions, The THS4531A is the better DC offset version, here is an old spec comparison I found - the THS4561 is probably a better part, but 3X the Icc. But the faster THS4561 might be able to do the entire gain in…
Part Number: OPA827
Hi team,
I have a question for 5.1. TI Precision Labs - Op Amps: Bandwidth 1. In this video, the input signal frequency is 200kHZ, the closed gain
is set to 100V/V. The GBW for OPA827 is 22MHZ. So, 200kHZ*100V/V=20MHZ<22MHZ, So, the…
Part Number: OPA827 Hi there,
I am learning Precision Labs 10.4 - Op Amps: Stability 4, and I am confused how can user get the curves between phase margin and overshoot % and AC gain peaking on page 11 and 16 of the PPT slide, as below. Seems there is…

Part Number: OPA827 Other Parts Discussed in Thread: OPA604 , OPA140 In a recent design update, we replaced an OPA604 with an OPA827 in a position as a voltage follower (buffer) at the input of an instrument. The input arrives on a BNC connector and feeds…
Part Number: OPA827 Hi ,
I have used 2 OPA827 to build a 2.5mA current source in my design.
a coto relay is inserted inbetween to cut out the current source when it is not used. my problem is that one of OPA827 is from time to time got destroyed.
any…
