Part Number: OPA856 Other Parts Discussed in Thread: LM828 , LM27761 , TPS60400 Hi ,
I'm using OPA856 Op-amp in my simulation as error amplifier. In this op-amp i need to give Negative Voltage supply for VS– Pin,
Here i've choosen LM828 (Switched…
Part Number: LM828 Other Parts Discussed in Thread: LM2776 , TPS60400 Hello E2E team.
I have a question about charge-pump capacitor for LM828.
Would it be possible for charge-pump capacitor to use of ceramic capacitor instead of electric capacitor…
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…
I had a spare PCB on which I mounted just the LDO and the LM828 without any other components on the board and bingo I now see the full -3.3V on the board. What am I missing here?
Hello Dajon,
You can check LM828 if it fits your application. See attached datasheet for reference. lm828.pdf

Part Number: TPS60151 Other Parts Discussed in Thread: TPS60400 , LM828 Hello:
We need +5v & -5V to bias TL2172 opamp. Output current will <5mA
We have any input from 3.3 to 5.5V
TPS60151 gives a regulated +5v
Which chip similar to this one will…
I would recommend scoping your power supply line. That ripple seems odd and roughly calculates to 17kHz, while the LM828 is specified for around 12 kHz. Nonetheless your charge pump power supply should be scoped to be sure it is not the cause of the problem…
Hello Lennert,
The PGA2311 datasheet is specific about the +/-5 V analog supplies and +5 V digital supply.
One way, an possibly the easiest way to meet these supply requirements and when only a single + 5 V supply is available, is to follow the+5…
Other Parts Discussed in Thread: LMP91200 , ADS1118 , ADS1120 , ADS1115 Hello! I want to use lmp91200 to measure pH in a tank and arduino is not capable of detecting differential voltage(like in lmp91200 case). I want to send the analog signal to only…
Hello,
I am reaching out to you from the Technical Support Team at NI to request, if possible, some assistance from your end. I am currently working with a customer who recently purchased several TI Power Electronics Boards for NI ELVIS III and noticed…
