LM10 Operational Amplifier and Voltage Reference August 2000 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.

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 Input offset voltage: That voltage which must be applied between the input terminals to bias the unloaded output in the linear region.

Common-mode rejection: The ratio of the input voltage range to the change in offset voltage between the extremes. Supply-voltage rejection: The ratio of the specified supply-voltage change to the change in offset voltage between the extremes.
