Part Number: OPA548 Hi support:
OPA548 works with bipolar power supply (+9V and -2.5V), the schematic diagram is as follows
Question 1:
When the output voltage of OPA548 is higher than V2, the op-amp shows positive voltage and current, that is, in source…
Part Number: OPA548 Hi team,
If the customer wants to increase the output current of the sine wave. Can use OPA548 to design?
Vin signal is +-3V 10mA capability. use Inverting amplifier with G=1. I hope output capability is V=+-3V ,currenct up to 2A
…
Part Number: OPA548 I am trying to design a non-inverting amplifier similar to the one given in Fig 26 of https://www.ti.com/lit/ds/symlink/opa548.pdf .
This is the circuit diagram. The input is a ramp signal with high voltage 3 V and low signal 0.2 Vp…
Part Number: OPA548EVM Other Parts Discussed in Thread: OPA548 I recently purchased the OPA548EVM eval board. Upon arrival, I took it out and began to set it up. After reviewing the datasheet, I connected the rails (AVDD, AVSS, GND) with +/- 6V and expected…
Part Number: OPA548 Dear e2e support,
My customer uses our OPA548 in a high temperature environment, causing it to go into thermal protection regularly.
Could you tell us how much is affected the OPA548 reliability (lifetime) under such conditions? …
Part Number: OPA548 Other Parts Discussed in Thread: DRV8412 Hi,
Does OPA548 operate stably with Unity Gain, 0.25 ohm load, and DC input? The customer's application is 3A constant current output.
In the evaluation by the customer, when 0V is input…
Part Number: OPA548 Other Parts Discussed in Thread: OPA192 , CSD18540Q5B Hi,
We are trying to design a current amplifier with the following requirements:
- An AC signal, isn't necessarily a sinusoidal.
- 10V <=Vout<=16V @ 15HZ - 15KHZ (or as close…
Part Number: OPA548 Hi, Team
I'd like to use OPA548 to build a bridge Howland current source, the schemaitc is posted as below. In the application the load is a coil, the series R8 and L1 is its equivalent circuit model, R8 is 5Ohm, and L1 is 150…
