Part Number: INA134 Other Parts Discussed in Thread: INA1651 , INA1650 Hello,
Looking at the INA134 datasheet it shows that the frequency response has a 2-3dB peak at 2MHz, which is also observable when measuring in real life.
What is the standard way…
Part Number: INA134 Other Parts Discussed in Thread: OPA2192 Hi,
INA134 differential input impedance is 50kOhm stated in datasheet.
And in the blog below:
Overlooking the obvious: the input impedance of a difference amplifier - Precision Hub - Archives…
Part Number: INA134 Other Parts Discussed in Thread: INA137 , , INA1651 Dear Madam/Sir, Currently, I utilized Woofer audio out (line+, Line-) differential signal as the input of Audio-to-LED strip (LED will be ON/OFF according to woofer audio frequency)…
Lucas,
The input resistance is listed for many amplifiers. You can find it in the same section as the input capacitance (see example below for OPA206). If the data sheet does not list the input impedance Marek provides a procedure for finding this value…
Hello Vinnie,
The DRV134 is a different architecture with a 50 ohm series output resistor that when tied to ground keeps the amplifier from shorting. The INA1650 outputs do not have this resistor, therefore the output shorts to ground if configured like…
Heiko,
Regarding the offset drift: I will mention your comment to the development team (i.e. that it would be good to specify drift over 0C to 85C). Over the full range the two products are somewhat comparable(0.6uV/C vs 0.8uV/C).
I will loop the product…
Other Parts Discussed in Thread: INA134 , DRV135 Hi,
I have an audio system where we are using a DRV135 and upto thirteen INA134 receivers over a twisted pair unshielded cable. the bus length is about 400meters with a receiver placed every 30 odd meters…
Part Number: INA137 Other Parts Discussed in Thread: INA134 , LME49720 , INA1620 Why is the through-hole version of the INA137 not recommended for new designs, "NRND," but the INA134PA is not?
The -6dB INA137 is more useful in pro audio applications…
Other Parts Discussed in Thread: INA2137 , INA137 , INA134 , INA2134 , TPS60403 , LM2664 Is it possible to use an INA134 or INA2134 (INA137/INA2137) with a single supply?
Either 5V, 12V, or 24V.
What would be the common mode and differential mode input voltage…
Other Parts Discussed in Thread: INA134 Hello,
I have a high voltage amplifier bridge circuit to drive a piezo (see attached diagram) and I find that the INA134 chip is damaged quite often in that it's output goes to the rails. I'm fairly sure that…
