Hello Michael,
The propagation delay on the output of the OPA861 will be controlled by the capacitor, noted Ccomp. If the capacitor is greater on one side than the other, the pole formed by the output impedance of the C output (current source) and Ccomp…
Other Parts Discussed in Thread: OPA861 , OPA615 , OPA2673 Hi.
I would like to make a laser diode driving circuit for M5-905-0100.
I want drive the laser diode with current varying from 20 to 200mA.
Applied signal is 225MHz PAM.
Can I use OPA861 and high…
Alex,
On +10V, the OPA861 can source/sink ±15mA, on +5V, this goes down to ±8mA, so to achieve 150mA drive, you will have to use 10x OPA861 in parallel. Each OPA861 will consume ~6mA quiescent current.
The maximum number of OPA861 the…
Hi Andree,
Thank you for your feedback. Here are some additional notes that may prove useful to you.
1) The OPA861 is using a very different architecture than the CA3080 or the CA3280 and as such teh lienarization technique used in the CA3x80 does not…
David,
You are correct, you can use two 9V batteries in series. The midpoint connection is ground. Use a 7805 on the +9V side referenced to ground to create +5V. Use a 7905 on -9V referenced to ground to regulate down to -5V. An additional 9V battery…
