OP2177 General Description
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 1,000 pF with no external compensation. Supply current is less than 500 µA per amplifier at 30 V. In-ternal 500 Ω series resistors protect the inputs, allowing input signal levels several volts beyond either supply with-out phase reversal.
Unlike previous high-voltage amplifiers with very low offset voltages, the OP1177 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 is identical to performance in the SOIC package.
OPx177 family offers the widest specified temperature range of any high-precision amplifier in surface-mount pack-aging. All versions are fully specified for operation from 40°C to +125°C for the most demanding operating envir-onments.
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 port-able instrumentationand controls-thermocouple, RTD, strain-bridge, and other sensor signal conditioning-and pre-cision filters.
The OP1177 (single) and the OP2177 (dual) amplifiers are available in the 8-lead MSOP and 8-lead SOIC packages. The OP4177 (quad) is available in 14-lead narrow SOIC and 14-lead TSSOP packages. MSOP and TSSOP packages are available in tape and reel only.
