... Unlike previous high voltage amplifiers with very low offset voltages, the OP1177 (single) and OP2177 (dual) amplifiers are available in tiny 8-lead surface-mount MSOP and 8-lead narrow SOIC packages. The OP4177 (quad) is available in TSSOP and 14-lead narrow SOIC packages. Moreover, specified performance in the MSOP and the TSSOP is identical to Rev ...

... OP1177/OP2177/OP4177 FUNCTIONAL DESCRIPTION The OPx177 series is the fourth generation of Analog Devices, Inc., industry-standard OP07 amplifier family. OPx177 is a high precision, low noise operational amplifier with a combination of extremely low offset voltage and very low input bias currents. Unlike JFET amplifiers, the low bias and offset currents are relatively insensitive to ambient temperatures, even up to 125° ...

... OP1177/OP2177/OP4177 PROPER BOARD LAYOUT The OPx177 is a high precision device. To ensure optimum performance at the PCB level, care must be taken in the design of the board layout. To avoid leakage currents, the surface of the board should be kept clean and free of moisture. Coating the surface creates a barrier to moisture accumulation and helps reduce parasitic resistance on the board ...

... The OPx177 is an ideal amplifier for thermocouple circuits because it has a very low offset voltage, excellent PSRR and CMRR, and low noise at low frequencies. It can be used to create a thermocouple circuit with great linearity. Resistor R1, Resistor R2, and Diode D1, shown in Figure 64, are mounted in an isothermal block.
