NSC LM10 Operational amplifier and voltage reference Datasheet

LM10
Operational Amplifier and Voltage Reference
General Description
The LM10 series are monolithic linear ICs consisting of a
precision reference, an adjustable reference buffer and an
independent, high quality op amp.
The unit can operate from a total supply voltage as low as
1.1V or as high as 40V, drawing only 270µA. A complementary output stage swings within 15 mV of the supply terminals or will deliver ± 20 mA output current with ± 0.4V saturation. Reference output can be as low as 200 mV.
The circuit is recommended for portable equipment and is
completely specified for operation from a single power cell.
In contrast, high output-drive capability, both voltage and
current, along with thermal overload protection, suggest it in
demanding general-purpose applications.
The device is capable of operating in a floating mode, independent of fixed supplies. It can function as a remote comparator, signal conditioner, SCR controller or transmitter for
analog signals, delivering the processed signal on the same
line used to supply power. It is also suited for operation in a
wide range of voltage- and current-regulator applications,
from low voltages to several hundred volts, providing greater
precision than existing ICs.
This series is available in the three standard temperature
ranges, with the commercial part having relaxed limits. In addition, a low-voltage specification (suffix “L”) is available in
the limited temperature ranges at a cost savings.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits.
Note 2: The Input voltage can exceed the supply voltages provided that the voltage from the input to any other terminal does not exceed the maximum differential
input voltage and excess dissipation is accounted for when VIN < V−.
Note 3: The maximum, operating-junction temperature is 150˚C for the LM10, 100˚C for the LM10B(L) and 85˚C for the LM10C(L). At elevated temperatures, devices
must be derated based on package thermal resistance.
Note 4: Internal thermal limiting prevents excessive heating that could result in sudden failure, but the IC can be subjected to accelerated stress with a shorted output
and worst-case conditions.
Note 5: These specifications apply for V−≤VCM≤V+−0.85V (1.0V), 1.2V (1.3V) < VS≤VMAX, VREF = 0.2V and 0≤IREF≤1.0 mA, unless otherwise specified: VMAX = 40V
for the standard part and 6.5V for the low voltage part. Normal typeface indicates 25˚C limits. Boldface type indicates limits and altered test conditions for
full-temperature-range operation; this is −55˚C to 125˚C for the LM10, −25˚C to 85˚C for the LM10B(L) and 0˚C to 70˚C for the LM10C(L). The specifications do
not include the effects of thermal gradients (τ1 ≅ 20 ms), die heating (τ2 ≅ 0.2s) or package heating. Gradient effects are small and tend to offset the electrical error (see
curves).
Note 6: For TJ > 90˚C, IOS may exceed 1.5 nA for VCM = V−. With TJ = 125˚C and V−≤VCM≤V−+0.1V, IOS≤5 nA.
Note 7: This defines operation in floating applications such as the bootstrapped regulator or two-wire transmitter. Output is connected to the V+ terminal of the IC
and input common mode is referred to V− (see typical applications). Effect of larger output-voltage swings with higher load resistance can be accounted for by adding
the positive-supply rejection error.
Note 8: Refer to RETS10X for LM10H military specifications.
Definition of Terms
Supply-voltage rejection: The ratio of the specified
supply-voltage change to the change in offset voltage between the extremes.
Line regulation: The average change in reference output
voltage over the specified supply voltage range.
Load regulation: The change in reference output voltage
from no load to that load specified.
Feedback sense voltage: The voltage, referred to V−, on
the reference feedback terminal while operating in regulation.
Reference amplifier gain: The ratio of the specified reference output change to the change in feedback sense voltage
required to produce it.
Feedback current: The absolute value of the current at the
feedback terminal when operating in regulation.
Input offset voltage: That voltage which must be applied
between the input terminals to bias the unloaded output in
the linear region.
Input offset current: The difference in the currents at the input terminals when the unloaded output is in the linear region.
Input bias current: The absolute value of the average of the
two input currents.
Input resistance: The ratio of the change in input voltage to
the change in input current on either input with the other
grounded.
Large signal voltage gain: The ratio of the specified output
voltage swing to the change in differential input voltage required to produce it.
Shunt gain: The ratio of the specified output voltage swing
to the change in differential input voltage required to produce
it with the output tied to the V+ terminal of the IC. The load
and power source are connected between the V+ and V− terminals, and input common-mode is referred to the V− terminal.
Supply current: The current required from the power
source to operate the amplifier and reference with their outputs unloaded and operating in the linear range.
Common-mode rejection: The ratio of the input voltage
range to the change in offset voltage between the extremes.

Application Hints
With heavy amplifier loading to V−, resistance drops in the V− lead can adversely affect reference regulation. Lead resistance can
approach 1Ω. Therefore, the common to the reference circuitry should be connected as close as possible to the package.
