With a maximum offset voltage of just 60 \u00b5V and maximum offset drift of 0.7 \u00b5V\/\u00b0C, the OP2177 provides outstanding DC precision for demanding measurement applications. The input bias current is specified at 2 nA maximum, and voltage noise density is 8 nV\/sqrt(Hz) typical. Despite drawing only 400 \u00b5A per amplifier, the device achieves greater than 120 dB CMRR, PSRR, and open-loop gain. The amplifiers are unity-gain stable and can drive capacitive loads up to 1000 pF without external compensation. Internal 500 ohm series resistors protect the inputs against signals exceeding the supply rails without phase reversal. Available in an 8-lead SOIC package rated for -40\u00b0C to +125\u00b0C operation.","working_principle":"The OP2177ARZ uses a precision bipolar input stage with trimmed and balanced input transistors to achieve the 60 \u00b5V maximum offset voltage. The input stage incorporates 500 ohm internal series resistors that protect the input differential pair from overvoltage conditions, allowing input signals to exceed the supply rails by several volts without causing phase reversal or damage. The amplifier topology uses a folded-cascode input stage feeding a high-gain intermediate stage, followed by a Class AB output stage capable of driving heavy loads. Internal compensation provides unity-gain stability with capacitive loads up to 1000 pF. The low 8 nV\/sqrt(Hz) input noise is achieved through careful optimization of the input pair operating current and device geometry. The 400 \u00b5A per-channel supply current balances precision performance against power consumption, making it suitable for both line-powered and battery-operated precision instruments.","pin_description":"
