GENERAL DESCRIPTION
The OP490 is a high performance micropower quad op amp
that operates from a single supply of 1.6 V to 36 V or from dual
supplies of ±0.8 V to ±18 V. 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 20 μA of quiescent supply
current per amplifier, but each amplifier is able to deliver over
5 mA of output current to a load. Input offset voltage is under
0.5 mV. Gain exceeds over 400,000 and CMR is better than
90 dB. A PSRR of under 5.6 μV/V minimizes offset voltage
changes experienced in battery-powered systems.
The quad OP490 combines high performance with the space
and cost savings of quad amplifiers. 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.
