Introduction

AI Translation

The OPx177 series consists of single, dual, and quad amplifiers with ultra-high precision, featuring extremely low offset voltage and drift, low input bias current, low noise, and low power consumption. Capacitive loads above 1000 pF are driven without external compensation while maintaining output stability. At a supply voltage of 30V, supply current per amplifier is less than 500 μA. An internal 500 Ω series resistor protects the inputs, allowing input signal levels to exceed either supply voltage by several volts without causing phase reversal. Unlike previous ultra-low offset voltage, high-voltage amplifiers, the OP1177 (single) and OP2177 (dual) amplifiers are available in compact 8-pin surface-mount MSOP and 8-pin narrow-body SOIC packages. The OP4177 (quad) amplifier is available in TSSOP and 14-pin narrow-body SOIC packages. Furthermore, devices in MSOP and TSSOP packages are rated to the same performance as those in SOIC packages. MSOP and TSSOP package products are available in tape and reel form only. Among all high-precision amplifiers in surface-mount packages, the OPx177 series offers the widest rated temperature range. All versions are rated for operation from -40°C to +125°C, making them suitable for the most demanding operating environments. Applications for these amplifiers include precision diode power measurement, voltage and current level setting, and level detection in optical and wireless transmission systems. Additional applications include line-powered and portable instrumentation and control circuits: thermocouple, RTD, strain bridge and other sensor signal conditioning, as well as precision filters.
