Part Number: OPA192 Other Parts Discussed in Thread: LM2664 , LM7705 , TLV387 Tool/software: Hi.
I have a problem with the OPA192.
OPA192 is used as a low impedance buffer to the input of the MCP2024 ADC.
From time to time, all of a sudden the OPA192 is…
Part Number: LM2664 Other Parts Discussed in Thread: LM2663
LM2664 seems to need about 3.48ms until output voltage becomes stable as a picture I attached. Why these time is required for LM2664? Also this waveform is correct?
Ch1: Input, Ch2: output…
Part Number: LM2664 Other Parts Discussed in Thread: TLV2711 , TPS65130
Hello. I wish to power the TLV2711 low power Op Amp, supplying ±5V.
When testing with my prototype, I used the USB 5V and LM2664M6X to create -5V.
Now, I have to use a LiPo…
Part Number: LM2664 I am designing a circuit for Vin = +3.3V i.e. to get -3.3V.
Please tell how to calculate the value of the charge pump capacitor C1 and the corresponding value for storage capacitor C2.
Is there any importance of Duty cycle in this…
Part Number: LM2664 Other Parts Discussed in Thread: BUF602
Hi, guys.
I'm using MSP-EXP430G2 and its ADC. The ADC will be connected to this bandpass filter.
The Op Amp circuit on the bottom is creating approx 1.6V.
I want the ADC's input signal…
Part Number: LM2664 Other Parts Discussed in Thread: INA828 ,
Hi, I'm using the MSP-EXP432P401R board with some Op Amps. Both +5V from the launchpad's USB and -5V will power the INA828 Instrumentation Amplifier.
May I ask
Q0. do both C1 and C2…

Part Number: ADS124S08 Other Parts Discussed in Thread: LM2664 , , LM828 Hi all,
I want to use the ADS124S08 with a +2.5vdc (AVDD) and -2.5vdc (AVSS) analog voltage supply, 3vdc for the digital supplies (DVDD and IOVDD). I'm wondering if I can use the REFOUT…
Part Number: LM2664
Hello.
During shutdown, just stop switching, all four intenal switches do not turn off?
Is it that LM2664 stops in either of the states below and we do not know which way to go?
S1,S3 = ON S2,S4 = OFF
or
S1,S3 = OFF S2,S4 = ON
Regards…
