To maximize such a high performance with stable operation, the NJM2739 should be operated by clean and low impedance supply voltage. So, the bypass capacitor should be connected to the NJM2739’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 NJM2739 3 4 6 V- Fig.1 Power Supply Bypassing Circuit ●Thermoelectric Effect The NJM2739 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 NJM2739. 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 NJM2739’s each input terminal metal. If there is thermal mismatch in-between NJM2739’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 NJM2739. To minimize this voltage difference, the thermal mismatch in-between NJM2739’s each input terminal and PCB metal should be minimized. ●Differential Amplifier Differential amplifier (see below Fig.2) is used in high accuracy circuit to improve common mode rejection ratio (CMR). 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.
