Hi Matt,
You should be able to expand on the two parallel power op amp connections shown in Fig. 14 of the OPA569 datasheet. The upper circuit showing "inputs connected in parallel" would simply involve connecting an A3, A4, etc. as A1 and A2 are connected…
Other Parts Discussed in Thread: OPA569 , TINA-TI i am planning to use OPA569 as a voice coil driver. my driving current requirement is just 250mA. so first question can i design a circuit with OPA569 which source only 250mA current? second question is…
Thank you for your feedback, it's really insightful. I have a follow-up question. I have tried simulating with several high-current opamps ( OPA569, OPA549, OPA567 etc). I have noted that they give good current output at low frequency and low inductance…
Part Number: OPA593 Other Parts Discussed in Thread: OPA552 , OPA521 , OPA548 , ALM2402F-Q1 , ALM2402-Q1 , OPA567 , OPA569 , OPA564 , OPA547 , OPA551 Hi all,
I was hoping to get some help selecting an alternative solution for the OPA593, the proposed application…
Hi Ludovic,
Errol has moved on to his next engineering rotation position and is no longer available to assist with your OPA569 application. He spent a great amount of time constructing and evaluating your application circuit and his findings about the…
Other Parts Discussed in Thread: TLV4113 , OPA567 , OPA569 Hi,
An application requires couple of TI op amps for a new circuit design.
The parts that are interested: TLV4113, OPA567, and OPA569.
The part needs to drive has reasonably high continuous output…
Other Parts Discussed in Thread: OPA569 I am using the OPA569 in a design and followed the 'basic connections' diagram in the datasheet (image copied below).
V+ is 5V DC from a power brick and V- is grounded.
What is the purpose of the 47uF capacitor…
Thank you for your answer. I just tried to add 1 uF and 10 uF capacitors. With 1 uF capacitor, no spike but strong reverse current is possible (> 30 mA). With 10 uF capacitor, just small negative current (30nA, I think it should not damage a laser diode…
Hi Marek and Frank,
I have continued testing on the TF of the OPA569. Additional measurements show a clear relation between the TF behavior and switch node of 5V supply (unfortunately I cannot add pictures to the post for some reason...).
As a next step…
Part Number: DAC8541 Other Parts Discussed in Thread: OPA569 , OPA335 , DAC80501 Dear e2e Support,
One of my customer intend to design a power booster on the output of our DAC8541, as seen fig 22 of our OPA569:
The question is to know if the OPA335 could…
