Part Number: OPA567 Other Parts Discussed in Thread: DAC8830 , OPA593 Tool/software: Hi TI expert
I designed to use the opa567 for the TEC temperature control of the laser. The voltage can be adjusted by the DAC8830 design, and the output is to Vset…

3. Output swing limit - the output swing limit is 0.2V for light load and good linear response, and 0.3V under heavy load. So, technically, you…
Part Number: OPA567 Hello team,
I have a question about step response curve of OPA567 datasheet.
There are two step response curves in datasheet p.9 and both show distortion in middle of the rising edge.
What causes the distortion?
It looks like a crossover…
Part Number: OPA567 Hello team,
Do you have Vcm vs offset voltage plot for OPA567?
There is no the plot in datasheet but my customer want to confirm its characteristics.
Best regards,
Part Number: OPA567 Other Parts Discussed in Thread: INA317 Hi，TI expert
I have a TEC application question when I use opa567. My schematic is shown in the pic below.
Vset is the voltage corresponding to the set temperature，Vth is the voltage fed back…
Part Number: OPA567 Hi,
There is damage issue with high temperature.
With start, it works well but output gradually get worse and there is no output finally.
For LD operation, V+: GND, V-: -3.3V
The questions are:
1. if V- supply current rating is lower…
Part Number: OPA567 Hello, Art
Where should the exposed thermal pad of OPA567 be connected?
When designing the circuit as shown above, should the exposed thermal pad be connected to -3.3V or GND?
Thank you.

Part Number: OPA567 Hello,
My customer designed an LD (Laser Diode) drive circuit(0A~2A) as shown below using the OPA567 and checked the simulation results as shown on the right through TINA tool.
However, when the actual circuit is implemented and tested…
Hi Raymond,
thanks for your answer. Please excuse my late response to your reply.
The PWM input is set for a required LED current (LED -- LA W57B) and then is not changed for a longer time. This is a quasi static input voltage at the OPA567.
Should phase…
