Hi,
DAC11001B best [performance is achieved using +/-5V or +/-10V reference. I suggest use REF7050 as reference source and use an op amp in an inverting configuration ti generate -5V and feed to DAC11001B ( OPA827 can be used as inverting buffer).
Please…
Part Number: THS4304 Other Parts Discussed in Thread: OPA211 , OPA827 , Is there a list of all the opamps that use the SiGe CMOS process? The THS4304 is one, the OPA211 and OPA827 are others. I'm hoping to get a complete list of all options so I don't have…
Part Number: OPA1642 Other Parts Discussed in Thread: OPA2140 , OPA827 , , OPA140 OPA827, OPA2140 & OPA1642 source impedance and distortion issue. Dear Sir/Madam, While reviewing the datasheet OPA1642, by chance, I learnt the specifications in chapter…
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…
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 ,
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…

Part Number: OPA827 Other Parts Discussed in Thread: LMC6001 Hello
I have a general question on JFET input op amps.
What are the main disadvantages or limitations to JFET opamps for precision applications?
HI Shadyn,
We have a few options of modern JFET input amplifiers offering better performance and precision than the legacy OPA111SM; however, these are not available on the PDIP or TO-CAN packages. The OPA627SM is a 45-MHz previous generation JFET amplifier…
Part Number: OPA827 Other Parts Discussed in Thread: TIPD122 We are developing a component test system and need to evaluate flicker noise. Having discovered T.I. Precision Labs 0.1Hz to 10Hz filter design, I am attempting to fabricate and populate the…
