Part Number: OPA2189 Other Parts Discussed in Thread: INA826 , TLV3502 Hi Team,
My cusotmer is surveying high accuracy current sensing solution for OCP(over-current protection) function, the OPA's output error needs to be < 2.4%(I think OPA2189 might…
Part Number: OPA2189 Other Parts Discussed in Thread: OPA2197 Hi teams,
My customer original use ADA4610-2 on compensation topology. Application is AC source.
But the test results THD worse than ADA4610-2.So could you provide a better suggestion to replace…
Part Number: OPA2189 Other Parts Discussed in Thread: OPA2182 , OPA189 Hello,
I require input offset and bias current temperature drift data of opa2189. The information is not given in the datasheet. In my design I use large resistors therefore the bias…
Part Number: OPA2189 Other Parts Discussed in Thread: OPA2140 , OPA2197 Hello
How can I reproduce the specified noise figures for the OPA2189 if source impedances are not well matched at both inputs? or is there another part where I can have similar or…
Part Number: OPA2189 Our customer ask us the following question to register the device in which Sn is used, and could you kindly tell us the detail?
Material: OPA2189IDGKR
1. Use Ni for grounding or not. : Yes / No
2. Thickness of outermost layer plating…
Part Number: OPA2189 Other Parts Discussed in Thread: OPA189 Hi,
I'm trying to reconcile the OPA2189's capacitive drive (see typ op fig 26 which implies 1nF is close to the max capacitive load) with the differential gain applications figure (54) that…
Part Number: OPA2189 Other Parts Discussed in Thread: THS4561 , OPA2140 , OPA2192 , OPA2210 I am prototyping with OPA2189 because its very low 1/f noise. I use it for the input differential stage with 2 opamps and found there is big offset which is different…
Part Number: OPA2189 Other Parts Discussed in Thread: LM7705 Hi, I'm designing using the OPA2189 in a simple differential amp configuration. I am also using the PSPICE model you supply to validate. I have a somewhat unexpected behaviour from the device…
