  TLV8801: performance over temperature

  TI Thinks Resolved

  Part Number: TLV8801 Team, My customer has a question I hope you can help with: We are currently using a TLV8801DBVT as the input stage of a pH amplifier. We are seeing that as the temperature of the component increases (to 140F) our reading drops...

  RE: Ultra-Low-Noise High-Input Impedance Amplifier for Low-Frequency Measurement Applications

  Hi Pawel, What is your application? What are available rail voltages? What is the circuit gain? Is 1/f noise an factor? Here are some suggestions. I am able to refine it further, if I have more information OPA227 OPA1611 and OPA1622 OPA209 ...

  RE: TLV8801: Compatibility with tps61098x and output series resistance

  Hello Prithi, Adding a R-C filter in series with the supply line will help. Since the quiescent current is so small (<1uA), a fairly substantial RC filter can be created with reasonable RC values. Also, The PIR sensor itself (if it is powered...

  RE: TLV8801: PSpice Model

  Hi Shinici, The TLV8801 SPICE model is actually a standard SPICE model. The SPICE model file is the .LIB file. The web naming is "unfortunate". It is not specific to TINA and can be used in any SPICE compatible simulator. Regards,

  MSP430F5419A: ADC input electrical spec

  TI Thinks Resolved

  Part Number: MSP430F5419A Hi, I use TLV8801 for ADC input buffer. I found OPA output will generate a sin wave, but if I remove the resistance between OPA and ADC, this sin wave is gone. OPA input is voltage divider. Ru=1MOhm, Rd=1MOhm. If I pass...

  RE: LPV821: noob question about op-amps

  Hello Kazola, For breadboarding with a DIP at similar supply current levels, I would recommend the TLV2401 ("P" version). There are also DIP adapter boards available to adapt the TLV8801 package to a DIP. These are listed in the 'Tools...

  RE: TINA/Spice/OPA170: OPA170AIDR -replacement for cheaper IC

  Hi Vladimir, The TLV8801 will not work in your current design because the maximum supply voltage is only 5.5V and you are using 10V. Also the bandwidth of the devices is 200 times less than the OPA170. I recommend to take a look at the TLV170. If...
