GENERAL DESCRIPTION
The OP290 is a high performance micropower dual 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 OP290 to accommodate input signals
down to ground in single-supply operation. The OP290 output
swing also includes ground when operating from a single
supply, enabling zero-in, zero-out operation.
The OP290 draws less than 20 μA of quiescent supply current
per amplifier, while being able to deliver over 5 mA of output
current to a load. Input offset voltage is below 200 μV, eliminating the need for external nulling. Gain exceeds 700,000 and
common-mode rejection is better than 100 dB. The power
supply rejection ratio of under 5.6 μV/V minimizes offset
voltage changes experienced in battery-powered systems. The
low offset voltage and high gain offered by the OP290 bring
precision performance to micropower applications. The
minimal voltage and current requirements of the OP290 suit it
for battery- and solar-powered applications, such as portable
instruments, remote sensors, and satellites. For a single op amp,
see the OP90; for a quad, see the OP490.

THEORY OF OPERATION
INPUT VOLTAGE PROTECTION
The OP290 can be operated on a minimum supply voltage of
1.6 V, or with dual supplies of ±0.8 V, and draws only 19 µA of
supply current. In many battery-powered circuits, the OP290
can be continuously operated for thousands of hours before
requiring battery replacement, reducing equipment downtime
and operating cost.
The OP290 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 provide a large amount of input protection, allowing
the inputs to be taken 20 V beyond either supply without
damaging the amplifier.
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 voltage
requirement of the OP290, combined with the flat discharge
characteristic of the lithium cell, indicates that the OP290 can
be operated over the entire useful life of the cell. Figure 18
shows the typical discharge characteristic of a 1 Ah lithium cell
powering an OP290, with each amplifier, in turn, driving full
output swing into a 100 kΩ load.
SINGLE-SUPPLY OUTPUT VOLTAGE RANGE
In single-supply operation, the OP290 input and output ranges
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 OP290 has voltage gain
equal to the specification in Table 1. Output current source
capability is maintained over the entire voltage range including
ground.

APPLICATIONS INFORMATION
Calibration of the transmitter is simple. First, the slope of the
output current vs. temperature is calibrated by adjusting the
span trim, R7. A couple of iterations may be required to ensure
that the slope is correct.
TEMPERATURE TO 4 MA TO 20 mA TRANSMITTER
A simple temperature to 4 mA to 20 mA transmitter is shown in
Figure 20. After calibration, the transmitter is accurate to +0.5°C
over the −50°C to +150°C temperature range. The transmitter
operates from 8 V to 40 V with supply rejection better than
3 ppm/V. One half of the OP290 is used to buffer the VTEMP pin
while the other half regulates the output current to satisfy the
current summation at its noninverting input.

From Equation 1 and Equation 2, it can be seen that if the span
trim is adjusted before the zero trim, the two trims are not
interactive, which greatly simplifies the calibration procedure.

VARIABLE SLEW RATE FILTER
LOW OVERHEAD VOLTAGE REFERENCE
The circuit shown in Figure 21 can be used to remove pulse
noise from an input signal without limiting the response rate to
a genuine signal. The nonlinear filter has use in applications
where the input signal of interest is known to have physical
limitations. An example of this is a transducer output where a
change of temperature or pressure cannot exceed a certain rate
due to physical limitations of the environment. The filter consists
of a comparator that drives an integrator. The comparator
compares the input voltage to the output voltage and forces
the integrator output to equal the input voltage. A1 acts as a
comparator with its output high or low. Diode D1 and Diode
D2 clamp the voltage across R3, forcing a constant current to
flow in or out of C2. R3, C2, and A2 form an integrator with the
output of A2 slewing at a maximum rate of
Figure 22 shows a voltage reference that requires only 0.1 V of
overhead voltage. As shown, the reference provides a stable
4.5 V output with a 4.6 V to 36 V supply. Output voltage drift is
only 12 ppm/°C. Line regulation of the reference is under
5 μV/V with load regulation better than 10 μV/mA with up to
50 mA of output current.

For an input voltage slewing at a rate under this maximum slew
rate, the output simply follows the input with A1 operating in
its linear region.
The REF43 provides a stable 2.5 V that is multiplied by the
OP290. The PNP output transistor enables the output voltage to
approach the supply voltage.
Resistor R1 and Resistor R2 determine the output voltage.

For the lowest temperature drift, parallel resistors can be used
in place of the variable resistor and taken out of the circuit as
