GENERAL DESCRIPTION
The OP490 is a high performance micropower quad op amp 0.5 mV. Gain exceeds over 400,000 and CMR is better than that operates from a single supply of 1.6 V to 36 V or from dual 90 dB. A PSRR of under 5.6 μV/V minimizes offset voltage supplies of ±0.8 V to ±18 V. The input voltage range includes changes experienced in battery-powered systems. the negative rail allowing the OP490 to accommodate input The quad OP490 combines high performance with the space signals down to ground in single-supply operation. The output and cost savings of quad amplifiers. The minimal voltage and swing of the OP490 also includes ground when operating from current requirements of the OP490 make it ideal for battery and a single supply, enabling zero-in, zero-out operation. solar-powered applications, such as portable instruments and The quad OP490 draws less than 20 μA of quiescent supply remote sensors. current per amplifier, but each amplifier is able to deliver over 5 mA of output current to a load. Input offset voltage is under
