PIN CONFIGURATIONS 8-Lead MSOP (RM-8) 8-Lead SO (R-8) A D8671 A D8672 GENERAL DESCRIPTION 8-Lead SO (R-8) 14-Lead TSSOP (RU-14) The AD8671, AD8672 and AD8674 are precision single, dual and quad amplifiers featuring very low noise, very low offset voltage and drift, low input bias current, 10Mhz bandwidth and low power consumption. Outputs are stable with capacitive loads of over 100pF. Supply current is less than 3 mA per amplifier at 30V. Applications for these amplifiers include high quality PLL filters, instrumentation--thermocouple, RTD, strain-bridge and other sensor signal conditioning-precision filters and professional quality audio. The AD8671, AD8672 and AD8674 are specified over the extended industrial (-40° to +125°C) temperature range. The AD8671, single, is available in the 8-lead MSOP and 8-lead SOIC packages. The AD8672, dual, is available in the 8-lead MSOP and 8-lead SOIC packages. The AD8674, quad, is Information furnished by Analog Devices is believed to be accurate and reliable.
