Tel: 781/329-4700 www.analog.com Fax: 781/326-8703 © Analog Devices, Inc., 2002 Precision Low Noise, Low Input Bias Current Operational Amplifiers FEATURES Low Offset Voltage: 60 V Max Very Low Offset Voltage Drift: 0.7 V/ C Max Low Input Bias Current: 2 nA Max Low Noise: 8 nV/ √Hz CMRR, PSRR, and AVO > 120 dB Min Low Supply Current: 400 A/Amp Dual Supply Operation: 2.5 V to 15 V Unity Gain Stable No Phase Reversal Inputs Internally Protected Beyond Supply Voltage APPLICATIONS Wireless Base Station Control Circuits Optical Network Control Circuits Instrumentation Sensors and Controls Thermocouples RTDs Strain Bridges Shunt Current Measurements Precision Filters 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 con- sumption. 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. Internal 500 Ω series resis- tors 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 and OP2177 are available in the tiny MSOP 8-lead sur- face-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 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 detec- tion in optical and wireless transmission systems. Additional applications include line powered and portable instrumentation FUNCTIONAL BLOCK DIAGRAM 8-Lead MSOP (RM-Suffix) IN IN V V+ NC NC 1 45 8 OP1177 NC OUT NC = NO CONNECT 8-Lead SOIC (R-Suffix) 1 2 3 4 8 7 6 5 IN V +IN V+ OUT NC NC NC NC = NO CONNECT OP1177 8-Lead SOIC (R-Suffix) 1 2 3 4 8 7 6 5 OP2177 IN A V +IN A OUT B IN B V+ +IN B OUT A 8-Lead MSOP (RM-Suffix) IN A IN A V OUT B –IN B +IN B V+ 1 45 8 OP2177 OUT A 14-Lead TSSOP (RU-Suffix) OUT A –IN A +IN A V+ +IN B –IN B OUT B –IN D +IN D V– OUT D –IN C OUT C +IN C 14 8 1 7 OP4177 14-Lead SOIC (R-Suffix) OUT B 7 8 +IN B 5 10 IN B 6 9 V+ 4 11 OP4177 IN A 2 13 +IN A 3 12 OUT A 1 14 OUT C +IN C IN C V IN D +IN D OUT D OP4177 and controls—thermocouple, RTD, strain-bridge, and other sensor signal conditioning—and precision 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. |
