Part Number: TLV2254 Tool/software:
Good afternoon! I'm working with an account that manufactured chambers to simulate different environmental changes. Their chamber sensing unit likely uses several repeats of the same/similar precision op-amp in a…
Part Number: TLV2254 Hey,
I've already design a three stages amplifier by using mic863 and all stages gain as 55.5, 11 and 1 and I'm using +/-2.5V dual power supply for this mic863, when i give 8mVp-p as input by varying frequency from 1KHz to 50KHz i…
Part Number: TLV2254 Hello, I am trying to simulate a circuit with TLV2254 but they are notable differences between the simulation and experiments I have made. Is there any way to correct the spice model for a more accurate simulation?
Thank you,
Hi Shinichi,
Shinichi Inoue said: The data sheet only has specifications for 5V-GND and ±5V, so is it not possible to output 1.45V or more at ±2.5V?
The simulation may have some issue. Per the TLC2254 , the linear operating range should be between -2.5 and…
Part Number: TLV2254 Other Parts Discussed in Thread: TLV9064 , dear all,
i'm in a project that need to amplify photodiode output current signal. after signal transfer from current to voltage, i need to amplify this signal multiply 300 through 3 OPA stages…
Part Number: TLV2254 Presently using two cascading amplifiers, and feeding in a very low voltage. The first stage gain is set to 84 and the second stage gain can be varied using a digital potentiometer to ensure that the circuit is tuned to give us the…
Other Parts Discussed in Thread: TLV2254 , TLV2454 Hello,
The customer is using TLV2254 in a voltage follower configuration (see attached). With a 5V supply and the + input sitting at 5V, the output does not get to 5V. It reaches around 4.5V - 4.7V and…
Hello Lothar,
I tested the TLV2254 simulation model and found that it does not work correctly when operated with a single supply; despite the the op amp being capable of powered by a single +2.7 to +16 V supply.
When I examine the model design I see…
