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	DIG	0.038
1	UA1	INA122UA	Instrumentation Amp SO8 package G = 5+200K/R	DIG	5.80	INA122 is good for gain to 10k - but has a Ft of around 200KHz. 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))
