Part Number: DAC8750 Other Parts Discussed in Thread: TIPD101 , TIPD102 , DAC8771 Hello Expert,
I have some question for configuration about below.
Could you please check and send it guide and document?
The DAC8750 is currently being used as the Source…
Hello,
I am not sure that the DAC161S997 would be the best solution for the application. Specifically your comment about the loop speed raises some concerns. The DAC161S997 utilizes a ΣΔ architecture, which has limited rate of change. Figure…

There are several circuits that use op amps and BJT or MOS pass devices to create current sources with high output impedance. Take a look at the following reference designs: TIPD101 , TIPD102 , TIPD107 and also the XTR110 and XTR111 integrated circuits…
Other Parts Discussed in Thread: DAC9881 , DAC8750 , TIPD101 , TIPD102 Hi Everyone,
I am looking for a DAC with current output. The current range i am looking for is from 10uA to 1mA.
I found some TI parts that can generate from 0 to 20mA.
Is there anything…
1.) They used a 10M resistor for the input resistor, which sets the effective input impedance for this circuit. The resistor from IN+ to GND is used for input bias current cancellation. This was useful for older BJT op amps where the input bias current…
Sainer,
I suspect your stability issues are more related to the feedback loop of the switching regulator as opposed to the op amp itself. In general, capacitive load or capacitance on the inverting feedback node causes stability issues. Also, the output…

Hello Christian,
Thanks for the PCB layout.
No need for C3. Connect pin 4 directly to the GND plane. Place a capacitor as close to pins 7 and 8 as possible (right between the pins and the via). In general I prefer to see the supply voltage traces on the…
