T he 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. T he OP490’s
output swing also includes ground when operating from a single
supply, enabling “zero-in, zero-out” operation.
T he quad OP490 draws less than 20
μ
A 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
μ
V/
°
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
μ
V/V minimizes offset volt-
age changes experienced in battery powered systems.
T he quad OP490 combines high performance with the space
and cost savings of quad amplifiers. T he minimal voltage and
current requirements of the OP490 makes it ideal for battery
and solar powered applications, such as portable instruments
and remote sensors.
