OP4177ARZ: 运算放大器SOIC-14封装
The OPx177 family consists of very high precision, single, dual, and quad amplifiers featuring extremely low offset voltage and drift, low input bias current, low noise, and low power consumption. Outputs are stable with capacitive loads of over 1000 pF with no external compensation. Supply current is less than 500 μA per amplifier at 30 V. Internal 500 Ω series resistors protect the inputs, allowing input signal levels several volts beyond either supply without phase reversal.
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 performance in the SOIC package. MSOP and TSSOP are available in tape and reel only.
The OPx177 family offers the widest specified temperature range of any high precision amplifier in surface-mount packaging. All versions are fully specified for operation from −40°C to +125°C 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 controls–thermocouple, RTD, strain-bridge, and other sensor signal conditioning–and precision filters.
OP1177与OP2177是高精度放大器单和双放大器,具有极低的失调电压与温漂、低输入偏置电流、低噪声、低功耗等特点。双放大器OP2177与单放大器OP1177的性能指标相同。对于1000pF以上的电容负载,在没有外部补偿的情况下,其输出稳定。在30V电源电压时,两个放大器的供电电流都小于500µA。其内置500欧姆串行电阻器可以保护输入信号,允许输入信号电平高出电源电压若干伏特,并保证无反相。
