LM10QML LM10QML Operational Amplifier and Voltage Reference Literature Number: SNOSAP1 LM10QML Operational Amplifier and Voltage Reference General Description The LM10 is a monolithic linear IC 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 com- parator, 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.

Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), θJA (package junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDmax = (TJmax - TA)/ θJA or the number given in the Absolute Maximum Ratings, whichever is lower.. Note 3: 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 VI< VS-. 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: Guaranteed parameter, not tested, Note 6: This defines operation in floating applications such as the bootstrapped regulator or two-wire transmitter. Output is connected to the VS+ terminal of the IC and input common mode is referred to VS- (see typical applications). Effect of larger output-voltage swings with higher load resistance can be accounted for by adding the positive-supply rejection error. www.national.com 6 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 VS+ terminal of the IC. The load and power source are connected between the VS+ and VS- terminals, and input common-mode is referred to the VS- terminal. 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. 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 VS-, 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. 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. 7 www.national.com LM10QML Definition of Terms LM10QML Typical Performance Characteristics (Op Amp) Input Current Common Mode Limits 20149719 20149718 Output Voltage Drift Input Noise Voltage 20149720 20149721 DC Voltage Gain Transconductance 20149722 www.national.com 20149723 8 LM10QML Output Saturation Characteristics Output Saturation Characteristics 20149725 20149724 Output Saturation Characteristics Minimum Supply Voltage 20149727 20149726 Minimum Supply Voltage Minimum Supply Voltage 20149728 20149729 9 www.national.com LM10QML Frequency Response Output Impedance 20149730 20149731 Typical Stability Range Large Signal Response 20149733 20149732 Comparator Response Time For Various Input Overdrives Comparator Response Time For Various Input Overdrives 20149734 www.national.com 20149735 10 LM10QML Follower Pulse Response Noise Rejection 20149737 20149736 Rejection Slew Limiting Supply Current 20149739 20149738 Thermal Gradient Feedback Thermal Gradient Cross-coupling 20149740 20149741 11 www.national.com LM10QML Shunt Gain Shunt Gain 20149743 20149742 Shunt Gain Shunt Gain 20149744 20149742 Shunt Gain Shunt Gain 20149743 www.national.com 20149744 12 LM10QML Typical Performance Characteristics (Reference) Line Regulation Load Regulation 20149745 20149746 Reference Noise Voltage Minimum Supply Voltage 20149748 20149747 Output Saturation Typical Stability Range 20149749 20149750 13 www.national.com LM10QML Typical Applications (Note 8) (Pin numbers are for devices in 8-pin packages) Op Amp Offset Adjustment Standard Limited Range With Boosted Reference 20149751 Limited Range 20149753 20149752 www.national.com 14 LM10QML Positive Regulators (Note 7) Low Voltage Best Regulation 20149754 20149755 Zero Output 20149756 Note 7: Use only electrolytic output capacitors. 15 www.national.com LM10QML Current Regulator Shunt Regulator 20149757 20149758 Required For Capacitive Loading Negative Regulator Precision Regulator 20149759 *Electrolytic 20149760 www.national.com 16 LM10QML Laboratory Power Supply 20149761 *VO=10−4 R3 HV Regulator 20149762 20149784 17 www.national.com LM10QML Protected HV Regulator 20149763 Flame Detector 20149764 *800°C Threshold Is Established By Connecting Balance To VRef.
