Part Number: LM3900 Other Parts Discussed in Thread: TINA-TI , LM348 , LM324 , LM358 , LM2900 Tool/software: Hi, Does anyone have a TINA-TI or PSpice model for the LM3900, I've been given a circuit diagram using two and I wanted to run some simulation on…
Part Number: LM3900 Hi Sir/Mam,
I am using LM3900N part in my design. Circuit image attached.
1.) 5V input given to Inverting input pin, Input current taking 0.25A. why this too much current taking for this 1channel input ? pls clarify. ( Attached figure…
Part Number: LM3900 Hi Team
I am debugging one of the board issue which has LM3900N. I could not understand the design configuration of below circuit. Could you please help to provide any application note for this?

Part Number: LM3900 I built up a simple audio amp using lm3900, gain of approximately 10, Inverting. Resistor between 12 volt supply and (+) non-inverting input is 270K, RFeedback from output to inverting input is 135K. Input resistor of 12k to inverting…
Part Number: LM3900 Other Parts Discussed in Thread: LM359 , , RC4136 , OPA2196 , OPA4196 Good Morning,
I'm working with a ~ 40yr old amp that has about half a dozen of your LM3900N's in it. My question, is there an up-grade to the LM3900N given it's age…
Other Parts Discussed in Thread: LM3900 , TL974 , LM324 , LM348 , TLV2262A Hi,
i started a new project, in that i am using a audio mixer LM3900 and TL974IPWR , for the simulation purpose i need the spice model for above par tnumbers.I could't find in the…
Hi Matt,
The LM2900 is a "Norton", or current-differencing amplifier. It is not a "normal" voltage input op-amp. The inputs will look like a diode to ground. It uses current instead of voltage.
You may want to look at the LM2900-N…
