Function

RESK[2]

RESK[1]

Analog Input

AK1

E34

Reference Resistor Connection. An off-chip 3.16 k

Ω

±1% resistor is connected between these the positive

resistor reference pin RES and a Kelvin ground contact

RESK. An on-chip negative feedback path will force the

1.20 V VREF Voltage onto RES, therefore forcing 252

µA of current to flow through the resistor.
