Part Number: OPA4188 Tool/software: Hi,
I need a amplifier for these applicatons:
High precision shunt current sensing
Thermocouple/resistance temperature detector (RTD) sensors measurement
Please share your alternative amplifier suggestions to ADA4522…
Part Number: OPA4188 Hi,
Say I am using Vs=+/-18V and there is a short at the output when trying to output +18V. Based on Figure 9 in the datasheet , at 85C for example, the output current (or Isc) will be ~16mA and at most 15V. Since the IC does not appear…
Part Number: OPA4188 Other Parts Discussed in Thread: OPA4187 We are trying to do AC and Transient modeling of a circuit with the OPA4188 and OPA4187 with TINA, and would like to get spice models for these devices. Where do we go to look for device models…
Part Number: OPA4188 Other Parts Discussed in Thread: OPA2188 , OPA2197 , OPA2192 , OPA4196 I'm using the OPA4188 to measure voltage drop across a .006 Ohm shunt resistor. My test setup is a programmable supply that I can vary from 0.6V to 5V which connects…
Part Number: OPA4188 Other Parts Discussed in Thread: LM224 , OPA4196 Hi team,
There are some problems in using OPA4188.
The triangle wave generator composed of lm244 in the original design circuit, but it is easily affected by temperature and the signal…
Part Number: OPA4188 Hi,
I am using OPA4188AIPWR for low side current sensing circuit. In the normal condition output I am getting is OK but if I introduce noise at the input I am not getting the exact waveform it's a noisy one. I am using first order…
Part Number: OPA4188
Hi,
The below LPF is built using OPA4188, I have following questions
1. The pole in feedback because of input capacitance (Ccm, Cd, Cstray and Req = RF||Rin), causes the zero in 1/beta plot as show at ~130kHz, plots are shown below…
