POT4b Bill of Materials


Please see POT4a bill of materials and make the following changes :

As desired populate all sections except that entitled "reference" ie don't populate RR1-RR4, UR1, CR1


For the reference section populate:

POT4b reference
NUM REFDES Part# Desc Source Price Notes
1 UR1 MAX6173AASA 2.5V voltage reference Maxim 6.64 2.5V, 5V, or 10V reference depending on application
1 CR1 PCC1853CT-ND 0.1uF EIA0805 25V Y5V DIG 0.052 require : 0.1u chip cap
1 DR1 BZT52C2V4-7-FDICT-ND 2.4V zener diode SOD-123 DIG 0.43 zener voltage should be appx 1/2 of the reference voltage
1 RR2 RHM10.0KCCT-ND 10k EIA0805 DIG 0.038
1 DL1, DL2 P514CT-ND green gull wing SMT 4.2mm LED P514CT-ND DIG 0.038
1 UA1 INA122UA Instrumentation Amp SO8 package G = 5+200K/R DIG 5.80 ALT : many - LT1167, INA128UA (Vsup > 32) gain equation may be different
1 RA1 RHM402FCT-ND (gain=502.5), open (gain=1) 402 ohm, EIA1206 resistor to set gain for INA122 DIG 0.047 for INA122 gain = 5+200K/(RA1 (RA2+RA3))
1 UA1 INA128UA Instrumentation Amp SO8 package G = 1 + 50K/5 DIG 5.80 ALT : many - LT1167, INA122UA (Vsup > 32) gain equation may be different
1 RA1 RHM100FCT-ND (gain=501), open (gain=1) 100 ohm, EIA1206 resistor to set gain for INA122 DIG 0.047 for INA128 gain = 1+50K/(RA1 (RA2+RA3))
