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.

High performance portable equipment and instruments
frequently use lithium cells because of their long shelf life, light
weight, and high energy density relative to older primary cells.
Most lithium cells have a nominal output voltage of 3 V and are
noted for a flat discharge characteristic. The low supply current
requirement of the OP490, combined with the flat discharge
characteristic of the lithium cell, indicates that the OP490 can
be operated over the entire useful life of the cell. Figure 21
shows the typical discharge characteristic of a 1 Ah lithium cell
powering an OP490 with each amplifier, in turn, driving full
output swing into a 100 kΩ load.

The OP490 can be operated on a minimum supply voltage of
1.6 V or with dual supplies of ±0.8 V drawing only 60 μA of
supply current. In many battery-powered circuits, the OP490
can be continuously operated for hundreds of hours before
requiring battery replacement, thereby reducing equipment
downtime and operating costs.
In single-supply operation the input and output ranges of the
OP490 include ground. This allows true zero-in, zero-out
operation. The output stage provides an active pull-down to
around 0.8 V above ground. Below this level, a load resistance of up
to 1 MΩ to ground is required to pull the output down to zero.
In the region from ground to 0.8 V, the OP490 has voltage gain
equal to the data sheet specification. Output current source
capability is maintained over the entire voltage range including
ground.

charging current symmetrically to yield positive and negative
ramps. The integrator is bounded by B, which acts as a Schmitt
trigger with a precise hysteresis of 1.67 V, set by Resistors R5,
R6, and R7, and the associated CMOS switches. The resulting
output of A is a triangle wave with upper and lower levels of
3.33 V and 1.67 V. The output of B is a square wave with almost
rail-to-rail swing. With the components shown, frequency of
operation is given by the equation
INPUT VOLTAGE PROTECTION
The OP490 uses a PNP input stage with protection resistors in
series with the inverting and noninverting inputs. The high
breakdown of the PNP transistors coupled with the protection
resistors provides a large amount of input protection, allowing
the inputs to be taken 20 V beyond either supply without
damaging the amplifier.

but this is easily changed by varying C1. The circuit operates

MICROPOWER SINGLE-SUPPLY QUAD VOLTAGEOUTPUT 8-BIT DAC
The circuit shown in Figure 23 uses the DAC8408 CMOS quad
8-bit DAC, and the OP490 to form a single-supply quad voltage
output DAC with a supply drain of only 140 μA. The DAC8408
is used in voltage switching mode and each DAC has an output
resistance (≈10 kΩ) independent of the digital input code. The
output amplifiers act as buffers to avoid loading the DACs. The
100 kΩ resistors ensure that the OP490 outputs swing below 0.8 V
when required.

Figure 24. High Output Amplifier
HIGH OUTPUT AMPLIFIER
The amplifier shown in Figure 24 is capable of driving 25 V p-p
into a 1 kΩ load. Design of the amplifier is based on a bridge
configuration. A amplifies the input signal and drives the load
with the help of B. Amplifier C is a unity-gain inverter which
drives the load with help from D. Gain of the high output
amplifier with the component values shown is 10, but can easily
be changed by varying R1 or R2.
SINGLE-SUPPLY MICROPOWER QUAD
PROGRAMMABLE GAIN AMPLIFIER
The combination of a quad OP490 and the DAC8408 quad 8-bit
CMOS DAC creates a quad programmable-gain amplifier with
a quiescent supply drain of only 140 μA. The digital code
present at the DAC, which is easily set by a microprocessor,
determines the ratio between the fixed DAC feedback resistor
and the resistance of the DAC ladder seen by the op amp feedback loop. The gain of each amplifier is:
VOUT
V IN
=−
256
n
where n equals the decimal equivalent of the 8-bit digital code
present at the DAC. If the digital code present at the DAC
consists of all zeros, the feedback loop opens causing the op
amp output to saturate. The 10 MΩ resistors placed in parallel
with the DAC feedback loop eliminate this problem with a very
small reduction in gain accuracy. The 2.5 V reference biases the
amplifiers to the center of the linear region providing maximum
output swing.
