Характеристики

OP490GPZ, Низковольтный, микромощный, 4-х канальный …The OP490GPZ is a high-performance micropower quad Operational Amplifier operates from dual supplies of ±0.8 to ±18V. The input voltage range includes the negative rail allowing the OP490 to accommodate input signals down to ground in single-supply operation. The output swing of the OP490 also includes ground when operating from a single supply, enabling zero-in, zero-out operation. The quad OP490 draws less than 20µA of quiescent supply current per amplifier, but each amplifier is able to deliver over 5mA of output current to a load. Input offset voltage is under 0.5mV. Gain exceeds over 400000 and CMR is better than 90dB. A PSRR of under 5.6µV/V minimizes offset voltage changes experienced in battery-powered systems. The minimal voltage and current requirements of the OP490 make it ideal for battery and solar-powered applications, such as portable instruments and remote sensors.
