Part Number: LM4140 I'm using the LM4140 ACM -1.0 as a voltage reference for some current shunt amplifiers and the ADC converter.
Input voltage is 3.3V(from an TLV70033 LDO with a 10uF cap output and threw a ferried bead, this rail is clean), input…
Part Number: LM4140 Other Parts Discussed in Thread: LM4040 Hello, I'm looking to build an interface circuit for a temperature sensor, probably a thermocouple with a 1k or 10kohm resistor.
I found this application note:
regarding the use of this voltage…
Part Number: LM4140 Other Parts Discussed in Thread: TL431 Although customer want to make 7.5Vin to 3.8Vout for LM4041CEM3X-ADJ, attached simulation results was less than 2Vout.
I think that current is enough (IRMIN(max.)<60uA), but actual measure was less…
Other Parts Discussed in Thread: LM4140 Dear e2e,
in the Datasheet for the LM4140 it states:
=======================================
The LM4140 is available in three grades (A, B, C) with 0.1% initial accuracy and 3, 6 and 10 ppm/°C temperature coefficients…
Part Number: ADC128D818 Other Parts Discussed in Thread: LM4140 Datasheet question regarding bypass caps for the adc128d818 VREF - in the adc128d818 datasheet it states
1) on page 4 it states "ADC128D818 allows two choices for sourcing VREF: internal or…
Part Number: ADS1256 Hello,
For our tests we use the ADS1256EVM connected to a microcontroller. We would like to measure as precisely as possible a signal witch can vary between 1.024 and 2.048 volts.
In order to measure this signal we have connected…
Other Parts Discussed in Thread: LM4140 Have been recopmmended the REF50xx or LM4140 family for low drift voltage regulators for a ADC.
Looks like the LM4140 will not work as it is not industrial temp.
external voltage Reference care abouts:
Low drift over…
Other Parts Discussed in Thread: LM4140 , LMP90080 Hi,
I am using 4 lmp90080 to measure 16 channel temperature using themocouple. For Vref I want to use lm4140.
My doubt is that one lm4140 is enough for 4 lmp90080 or i have to use 4 lm4140 is required…
Other Parts Discussed in Thread: ADS1247 , ADS124S08 , REF200 , LMP2011 , LM4140 , INA317 , TLV333 Hi,
I'm looking for PT100 frontend analog circuit ICs for -10C to 140C temperature measurements.
Can you suggest on ICs?
