Regarding Shutdown function of LMC8101 Datasheet P15
Is it correct to understand that when…
Part Number: LMC8101 Hello,
This opamp has two V+ pins (and one V- pin). In order to bias it properly, do we need to connect the positive supply voltage to both V+ pins, or one can be floated/grounded?
Thanks,
Nima
Part Number: LMC8101 Other Parts Discussed in Thread: LMC7101 , OPA725 , TLV2771 , TLV2770 , OPA726 Hi,
Could you please provide the PCN for the LMC8101MM? Additionally please provide replacement part recommendation. Thank you!
Part Number: LMC8101 Hello, we are attaching this device to an FR4 substrate and experiencing a small % of failures that appear to be caused by a poor connection to the input pins B3 and C3. We recently cross sectioned a failure to find out what is happening…
Hi Antonio,
The lowest cost BGA / CSP device would be the LMC8101 that would fit this application and can run the entire supply voltage range (3.5V - 8V).
TINA-TI simulation looks fine and the MOSFET seems to stay in the Saturation region, where you…
Hi Lionel,
The LMC6482 TINA-TI macromodel does not have adequate input capacitance (~3pF) included. For that, the loop gain analysis I showed you earlier shows some strange behavior starting around 2-4 kHz which makes it look like phase margin is always…

I am using LMC6572 op amps, and need to maintain low input current ( <1pA) even when the circuit is not powered. As it is now, current…
Hi Marceli,
the output current of XTR111 must be limited to less than 50mA or you risk that the XTR111 becomes damaged. The XTR111 is not designed to output a current of 100mA.
I would think about using the improved Howland current pump:

Part Number: OPA547 Other Parts Discussed in Thread: TINA-TI Team,
We are using the OPA547 for an "improved Howland current pump" to turn voltage to a 0–20 mA output.
It works ok until a given input voltage level. When this input voltage is reached…
