Hot-selling and scarce OP1177AR Low Input Bias Current Operational Amplifiers MSOP8 spot stock

Product Descriptions

The OPx177 family consists of very high-precision, single, dual,and quad amplifiers featuring extremely low offset voltage anddrift, low input bias current, low noise, and low power consumption . Outputs are stable with capacitive loads of over1,000 pF with no external compensation . Supply current is lessthan 500 µA per amplifier at 30 V . Internal 500 Ω series resistors protect the inputs, allowing input signal levels several voltsbeyond either supply without phase reversal .

Unlike previous high-voltage amplifiers with very low offset voltages,theOP1177 and OP2177 are available in the tiny MSOP 8-lead surface-mount package,while the OP4177 is available in TSSOP14 .Moreover, specified performance in the MSOP/TSSOP package isidentical to performance in the SOIC package .

OPx177 family offers the widest specified temperature range ofany high-precision amplifier in surface-mount packaging . Allversions are fully specified for operation from –40°C to +125°C forthe most demanding operating environments .

Applications for these amplifiers include precision diode powermeasurement, voltage and current level setting, and level detection in optical and wireless transmission systems . Additionalapplications include line powered and portable instrumentation and controls—thermocouple, RTD, strain-bridge, and othersensor signal conditioning—and precision filters .
