LT1013CD - Dual Precision 1MHz Op Amp | Texas Instruments
MPN: LT1013CD ✓ Hoạt độngLT1013CD Tóm tắt
An operational amplifier is an analog signal-processing semiconductor that uses high open-loop gain to amplify voltage differences accurately. Within the broader hierarchy, an operational amplifier is a linear amplifier, analog IC, and signal-conditioning component. The LT1013 fits precision instrumentation because its dual configuration supports common differential, summing, filtering, threshold, or transimpedance stages while reducing board area.
Verified product information identifies high gain, low noise, low supply current, and a low-offset-voltage temperature coefficient as principal family characteristics. The device can operate from a single 5 V supply, has a common-mode input range that includes ground, and produces output swings to within a few millivolts of ground, as stated in the supplied comparison-source material. These properties are useful in battery-powered measurements where larger supply headroom would be inconvenient.
The LT1013 family supports broad supply operation from 4 V to 44 V, allowing the same precision amplifier architecture to serve low-voltage instrumentation and higher-voltage industrial signal chains. Its 1 MHz gain-bandwidth product supports moderate-bandwidth closed-loop functions rather than high-speed waveform or communications applications. The 0.4 V/us slew rate likewise favors low-frequency precision conditioning over wideband pulse acquisition.
Analog Devices lists battery-powered precision instrumentation, strain-gauge signal conditioners, thermocouple amplifiers, instrumentation amplifiers, 4 mA to 20 mA current-loop transmitters, multiple-limit threshold detection, and active filters as representative LT1013 applications. These uses benefit from dual-channel operation, low supply current, precision behavior, and the ability to work across single and split supplies.
When designing with the LT1013CD, preserve the required bypass capacitance, maintain common-mode and output headroom, and confirm that closed-loop bandwidth matches the 1 MHz family characteristic. Check noise, offset, supply current, and common-mode limits against the actual precision requirements. Pricing shown for LCSC is $0.4097 as of 2026-10-22; other distributor prices and current stock must be confirmed at purchase.
This page combines verified manufacturer and distributor information, packaging details, applications, pricing context, and engineering guidance. It also identifies which parameters remain unavailable in the supplied evidence instead of estimating them, enabling engineers to make a more defensible LT1013CD selection.

Ứng dụng tiêu biểu
LT1013CD phù hợp cho 6 Áp dụngs: Battery-Powered Precision Instrumentation, Strain-Gauge Signal Conditioning, Thermocouple Amplification, 4 mA to 20 mA Current-Loop Transmitters, Active Filters and Gain Blocks, Threshold Detection and Limit Monitoring.
Battery-Powered Precision Instrumentation
The LT1013CD fits battery-powered precision instrumentation because it combines two amplifiers, low-power operation, and a verified 4 V to 44 V supply range. According to Texas Instruments, the family also provides high gain, low noise, low supply current, and a low-offset-voltage temperature coefficient. Each channel can implement gain, buffering, summing, or active filtering where the 1 MHz gain-bandwidth product is sufficient. Designers should still verify input bias current and supply-current values against the source impedance and battery budget, because those numerical limits were not supplied.
Được đề xuất
Strain-Gauge Signal Conditioning
The LT1013CD is appropriate for low-frequency strain-gauge excitation and return-path conditioning because the LT1013 family emphasizes high gain, low noise, and low offset-voltage temperature coefficient. Its 1 MHz gain-bandwidth product allows useful closed-loop bandwidth below the device's unity-gain frequency, while two amplifiers can form gain or filtering stages without requiring another dual package. The 4 V minimum supply also supports compact low-voltage bridges. Exact input bias current and noise values must be checked before selecting amplifier topology.
Được đề xuất
Thermocouple Amplification
The LT1013CD can amplify the small voltage produced by a thermocouple because the family is designed for precision gain and low-noise signal conditioning. Two amplifiers provide useful flexibility for instrumentation stages, filters, or gain blocks, while the verified 5 V single-supply capability simplifies low-energy measurement systems. Since thermocouple accuracy can be limited by input bias current, offset, and drift, those parameters must be verified in the official data sheet before choosing resistor values and calibration strategy.
Được đề xuất
4 mA to 20 mA Current-Loop Transmitters
The LT1013CD fits 4 mA to 20 mA current-loop transmitter front ends because Analog Devices identifies current-loop transmitters as an LT1013 application. The dual precision configuration can amplify a sensor signal and support filtering in a compact eight-pin SOIC package. A 5 V supply is within the verified 4 V to 44 V operating range, while the common-mode input range includes ground. Designers must confirm output-current capability, loop compliance requirements, offset, and bias current from the complete device data before finalizing the transmitter.
Được đề xuất
Active Filters and Gain Blocks
The LT1013CD is suitable for active-filter and multiple-gain-block positions listed for the LT1013 family. Its 1 MHz gain-bandwidth product is more than adequate for many low-frequency sensor filters, and the 0.4 V/us slew rate helps preserve large-signal behavior at moderate frequencies. Both amplifiers are independent, allowing two filters, two gain stages, or one filter plus one buffer in the same 8-pin SOIC. Exact noise, gain error, and stability limits should be verified before selecting closed-loop gain and compensation values.
Được đề xuất
Threshold Detection and Limit Monitoring
The LT1013CD can support multiple-limit threshold detection because the LT1013 family combines precision gain with two amplifiers in one package. One channel can amplify the monitored signal, while the other can compare it with a reference or provide hysteresis. The low-power characteristic is beneficial in unattended instrumentation, and operation from a single 5 V supply helps reduce system complexity. Input offset, input bias current, output swing, and temperature drift must be checked numerically because those values are absent from the supplied evidence.

Ghi chú thiết kế
Do not treat the family-level LT1013 specifications as proof that every ordering code has identical temperature, offset, or qualification limits. Confirm the exact LT1013CD ordering row and electrical table in the Texas Instruments documentation. Likewise, do not accept a dual op amp merely because it uses an 8-pin SOIC package; verify pin functions, common-mode limits, output swing, supply span, offset, bias current, noise, bandwidth, and stability requirements before substitution.
Design power-supply bypassing around the manufacturer's recommendations and keep traces short. The verified LT1013 family supports 4 V to 44 V operation and a single 5 V supply, but the available evidence does not contain exact supply-current or capacitor values. Use the official data sheet for minimum capacitance and ESR or stability requirements. Estimated: power dissipation is calculated as P = (VIN - VOUT) × IOUT plus quiescent power, using the final operating voltage, load current, and measured supply current rather than an assumed value.
Keep sensor inputs and feedback components away from switching nodes and noisy return paths because precision amplification can amplify both interference and offset. The verified 1 MHz gain-bandwidth product supports moderate-bandwidth closed-loop designs, while 0.4 V/us slew rate limits large-signal response. Calculate closed-loop bandwidth, output swing, and slew-rate requirements, and place compensation or filter components directly at the relevant amplifier pins.
