Part Number: OPA227 Other Parts Discussed in Thread: OPA277 In the datasheet for the OPAx2 2 7 parts, Figure 15 shows the typical bias current change over temperature. I'd like to clarify my interpretation of this graph, as these typical bias currents …
Part Number: OPA227 Hi Team, My customer is evaluating offset voltage of OPA227 under thermostat bath. He said offset voltage is slightly different (~0.5uV) between before and after ambient temperature cycling. (20°C -> 90°C -> 20°C) Is it…
Other Parts Discussed in Thread: CSD17585F5 , OPA2277 , OPA197 , OPA277 , OPA191 , OPA192 , INA149 Hello,
The purpose of our system is to measure a 80VAC signal generated by an independent power supply (Totally different ground) , and convert it into a -/+ 10…
Other Parts Discussed in Thread: OPA227 , OPA197 Hi,
I am planning to use OPA227 in my application to attenuate a single ended signal.
As this support is wide supply input range from 5V - 36V (+/-2.5V to +/-18V)
Can I bias this opamp using +5V Dc supply…
Other Parts Discussed in Thread: OP07 , OPA227 , LM324 Hi,
I am using OP07 and OPA227 opamps for my analog filtering circuits. I have a problem with OP07 and OP227 with single supply mode. It is running fine when I use dual supply but on single supply…
Hi Katlynne Jones,
Thank you. I reviewed this application circuit. To drive the Op-Amp (OPA227), is it required +/- Dual 5V supply or Single supply 5V?.
In my design, only 5V supply is available.
Regards,
Gopal

I need to implement a buffer for VcomDA of a codec, and i only have OPA227 or OPA1642...
The VComDA is 2.5V DC voltage as i'm using…
Darren,
The values that you mentioned for the resistors are correct (they are also listed in the datasheet as 12kΩ typical). With those values, you would see the currents that you mentioned as well.
As for the filtering, I guess you could use a…
I simulated the RL=10K / 600ohm in TITINA, the OLG is only 155 dB which is different from the data sheet OLG=160dB for OPA 227.

Part Number: ADS1258 Other Parts Discussed in Thread: OPA227 I am using the ADS1258 in a design that requires high DC accuracy.
First of all, is the "external chopping" functionality even available when sampling single ended inputs? I got the impression…
