Hi Henry,
Below a couple of ideas:
The INA592 difference amplifier configured on G=2 has a differential input impedance of 6kΩ + 6kΩ = 12kΩ. Since the sense resistor is 1kΩ and relatively large compared to the 12kΩ input impedance of…
Part Number: OPA2320 Other Parts Discussed in Thread: ADS127L11 , , OPA2206 , PGA280 Hello TI,
I'm working on a signal chain that inputs into an ADS127L11 for measurement. The chain was designed and simulated specifically for low noise.
Unfortunately…
Part Number: TL074 Other Parts Discussed in Thread: , OPA2206 , OPA206 , OPA2310 , TLV9154 Hi team,
Could inverting/ no-inverting input be high impedance when VCC not powered? Thanks.
The inputs are diode-clamped to the power supply, so even with a current-limiting resistor, some current will flow from the input into the power supply, and can partially power up the TLV9001 or anything else connected to that supply.
You should use an…
Sasaki-san,
The OPA2205 datasheet was just recently released and it looks like there is at least one "bug" that didn't get caught. You are correct about Fig. 6-22, its title states "Voltage Noise Density vs Frequency", but in reality it…

Hi Art,
In OPA1671, I believe that that input voltage can only be approx. 0.3V above V+ supply, which is zero.
What is the application? OPA1671 is audio amplifier. If this is battery application, I would recommend OPA2206 , which it has input overvoltage…
