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. Input voltage range includes

the negative rail allowing the OP490 to accommodate input

signals down to ground in single-supply operation. The

OP490’s output swing also includes ground when operating

from a single supply, enabling “zero-in, zero-out” operation.

The quad OP490 draws less than 20

mA 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 with offset drift below 5

mV/∞C over the military

temperature range. Gain exceeds over 700,000 and CMR is

better than 100 dB. A PSRR of under 5.6

mV/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.
