Part Number: OPA2544 Tool/software: I am designing a voice coil driver to drive a Fast Steering Mirror. I have found some similar designs on this forum, and basing my design on these. The coil resistance is 8 ohms, and I estimate the inductance ~200uH…
Part Number: OPA2544 Other Parts Discussed in Thread: OPA541 Hi
May I know if there is a layout guideline for OPA2544?
if not, is there any other reference guideline that can apply?
Thanks.
Part Number: OPA2544 hi,
we are using an OPA2544 dual amplifier as Bridge Driver Circuit is shown in figure 4 in datasheet document. The power supply is ±35 V and power consumption is less than ratting. we use a good heat sink and ESD safety is taken into…
Hello Jim,
Yes, you are observing crossover distortion from the OPA2544 at 50 kHz. The gain-bandwidth where the open-loop gain is 1 V/V for the OPA2544 is specified with a typical value of 1.4 MHz. Therefore, at 50 kHz there isn't much open-loop gain (Aol…
Part Number: OPA2544 Hi Team,
My customer are looking for a amplifier which can output the signal with the voltage larger than 50V.
So I have found that the OPA2455 can support the ±35V supply voltage, and can swing to Vcc-+1 and Vcc+-1V.
1.Can…
Thank you for the detailed answer.

Other Parts Discussed in Thread: OPA2544 I am currently simulating the OPA2544/544 as a Howland current source using TINA from the TI site. The model is correctly holding the current I am expecting at .6A with a 10ohm load. However, I am checking the total…
