To maximize such a high performance with stable operation, theNJMOP177 should be operated by clean and low impedance supply voltage. So, the bypass capacitor should be connected to theNJMOP177’s both power supply terminals (V+ and V-) as shown in Fig.1.The bypass capacitors should be placed as close as possible to IC package V+ 2 7 − NJMOP177 3 + 6 4 V- Fig.1 Power Supply Bypassing Circuit ●Thermoelectric Effect The NJMOP177 is a high precision operational amplifier featuring low offset voltage and low offset voltage thermal drift. To achieve such a high performance, take care about thermoelectric effect possibly occurs on each input terminal of the NJMOP177. Generally, if there are thermal mismatches at the junction of different types of metals, the thermoelectric voltage (Seebeck effect) occurs at the junction. The thermoelectric voltages possibly occur at the junction of PCB metal patterns and NJMOP177’s each input terminal metal. If there is thermal mismatch in-between NJMOP177’s each input terminal metal, the thermoelectric voltages generated on each input terminal possibly have different voltage each. This voltage difference causes offset voltage and offset voltage thermal drift of the NJMOP177. To minimize this voltage difference, the thermal mismatch in-between NJMOP177’s each input terminal and PCB metal should be minimized. ●Offset Voltage Adjustment The NJMOP177 has offset voltage trim terminals (pin1 and pin8) as shown in below Fig.2. By connecting external potentiometer in the range of 20Kohm, the offset voltage trim range is ±3mV. This offset voltage trim is effective only for offset voltage at room temperature, not for offset voltage thermal drift. If offset voltage adjustment is not in use, leave pin1 and pin8 open (un-connected).

A matching between the ratio R1/R2 = R3/R4 and R1=R3 makes the high CMR. For example, acceptable error range to obtain CMR of 130dB or more is about 0.1ppm.
