Ian,
I have put together a simulation showing how to take a differential signal from either the CXD3782 or LM27762 and inputting the differential signal into the OPA1656 to convert to single ended. The simulation can be found at the bottom of this post…
Part Number: ADS1284 Other Parts Discussed in Thread: LM27762 , REF6250 We are evaluating ADS1284 and during our tests, on our prototype board, we have noticed that while we achieve very similar SNR (RMS noise) numbers to the datasheet, we are seeing…
Part Number: PCM5102A Other Parts Discussed in Thread: OPA1678 , LM27762
Hi,
Sometime ago I asked you a question about possibility of using op-amp with PCM5102A to have higher Vrms at lower loads than 10k and you recommended me to use something like…
Part Number: INA818 Other Parts Discussed in Thread: LM27762 , , INA126 , INA826 , INA828 , INA333 , TPS65133 , OPA365 Hello,
I need to amplify a signal with hundreds of mV DC + tenths of mV AC at tenths of kHz. The voltage signal will be read between…
Part Number: ADS1262 Other Parts Discussed in Thread: TPS60403 , LM27762 , TPS61220 I'm revisiting this project. I have the ADS1262 working with my loadcell on a 0-5v supply, but would like to run it off a single cell battery.
I found this document…
Part Number: TPS60403 Other Parts Discussed in Thread: LM27762 , , ADS1294 , ADS1298 , LM2776 Can someone help me find an alternative part for TPS60403 for using it along with ADS1294 (ECG FE ADC) application. I am not able to find TPS60403 on any of…
Hi Nick,
The nominal AC gain of my proposed circuit is equal to 20log(R3/R1)+6dB=20log(10k/330) + 6dB = 35.6dB. If you could change the resistor value R1=10k, R3=200k, the Ac gain is equal to 32dB.
While, the cut-off frequency of low frequency side…
Part Number: ADS1291 Other Parts Discussed in Thread: LM27762 customer currently evaluating the ADS1291
trying to use LM27762 for the supply voltage, but seems to have too much consumption for the wearable device.
is there other voltage supply reference…
Hi Ryan,
the LM27762 could also do the trick. You could generate +5V with the LM2596 and generate +/-2.5V by the help of LM27762. The +5V for the comparator could be taken from the +5V of LM2596.

Emil,
I'll just throw out a few comments to start out. If the internal reference is being used, the unused REFP and REFN can be left floating. However, the LMP2234 isn't able to drive much capacitive load. I don't know if LMP2234 can drive that much…
