Part Number: OPA547 Other Parts Discussed in Thread: OPA170 Hi,
We are using OPA547 in one of our programable power supply design where the voltage can be varied from -5V to 5V & Ilimit current is set to 200mA. In this section when ever the voltage is…
Part Number: OPA547 Other Parts Discussed in Thread: TINA-TI Hi,
I am using OPA547 OP-AMP for our new project and I am using the below approach for limiting the current:
I am using a 100K digital potentiometer instead of a variable resistor to control…
Part Number: OPA547 Hello Guys,
Good day.
I see a theta JC on the data sheet and a theta JA. I would like to know what the case resistance represents. Is it the thermal resistance from the junction to the ground slug? Do you have a value for that thermal…
Part Number: OPA547 Other Parts Discussed in Thread: STRIKE , OPA549 I have a design using the OPA547 that has a 10 ohm resistor in series with the output. This just to aid in stability. Anyway, the resistor is between the output of the amplifier and the…
Part Number: OPA547 Other Parts Discussed in Thread: DAC7811 , , DAC7800
Hi Team,
Good day.
Customer is looking to control the current limit feature of the opa547, using a DAC on the Ilim pin. Customer tried the DAC7811 12bit current output spi dac with…
Part Number: OPA547 Hello Team,
My customer is looking for the ESD rating of OPA547. Can you share this information with us? Also, the website shows that this device operating temperature is –40°C to +85°C, while the datasheet shows –40°C…
Part Number: OPA547 Other Parts Discussed in Thread: TINA-TI Hi All,
I am using OPA547 to generate a voltage source using a DAC. My DAC feeds a voltage to OPA547 which is currently used in non-inverting configuration. OPA547 multiplies it with a fixed…
Part Number: OPA547 Hi Team,
One of my customers is using OPA547 in a programmable power supply .They need to set the current limit through a digital pot .
They are able to do the same in simulation but they need the formula for feeding it into uC .
…
Part Number: OPA547 Other Parts Discussed in Thread: TINA-TI Team,
We are using the OPA547 for an "improved Howland current pump" to turn voltage to a 0–20 mA output.
It works ok until a given input voltage level. When this input voltage…
