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 sig-
nals 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
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 with offset drift below 5
µV/°C
over the military tem-
perature range. Gain exceeds over 700,000 and CMR is better
than 100 dB. A PSRR of under 5.6
µV/V
minimizes offset volt-
age 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 makes it ideal for battery
and solar powered applications, such as portable instruments
and remote sensors.
