Rail-to-rail output swing Low supply current: 500 μA typical per amplifier Wide bandwidth Gain bandwidth product (AV = 100): 3.5 MHz typical Unity-gain crossover (AV = 1): 3.5 MHz typical −3 dB bandwidth (AV = 1): 6 MHz typical Dual-supply operation Specified at ±5 V to ±15 V, operates over ±2.5 V to ±18 V Unity-gain stable No phase reversal APPLICATIONS Wireless base station control circuits Optical network control circuits Instrumentation Sensors and controls Thermocouples, RTDs, strain gages, shunt current measurements GENERAL DESCRIPTION
The ADA4177-2CHIPS is a dual-channel amplifier that features signal excursions 32 V beyond either supply, as well as 70 dB of low offset voltage (3 μV typical), low input bias current, low rejection for electromagnetic interference (EMI) at 1000 MHz. noise, and low current consumption (500 μA typical). Outputs Additional application and technical information can be found are stable with capacitive loads of more than 1000 pF with no in the ADA4177-2 data sheet. external compensation. The ADA4177-2CHIPS is specified for +25°C only, and is The inputs of the ADA4177-2CHIPS feature outstanding functional over the −40°C to +125°C temperature range. The precision amplifier robustness, providing input protection against ADA4177-2CHIPS is guaranteed only on the specifications of this data sheet.
