LT1013DD - Dual Precision 5V-44V Op Amp | Texas Instruments
MPN: LT1013DD ✓ AktifLT1013DD Ringkasan
An operational amplifier is an active analog signal-processing device that uses feedback to amplify the difference between its inverting and non-inverting inputs. The dual LT1013 provides two amplifiers in one package, allowing designers to implement two signal paths without using separate packages. In the broader semiconductor hierarchy, the LT1013DD is an analog integrated circuit, specifically a precision operational amplifier used within instrumentation and embedded signal-conditioning systems.
The verified product information identifies the LT1013DD as a standard general-purpose dual amplifier with an 8-SOIC package and a 0 °C to 70 °C operating-temperature range. The TI product-page snippet describes the LT1013D as a low-power device with a 5 V to 44 V wide supply range. The wider LT1013 product page states a 4 V to 44 V supply range, so the exact minimum operating supply for the selected LT1013DD ordering option should be confirmed against the manufacturer datasheet before design release.
The LT1013DD is suited to battery-powered precision instrumentation, strain-gauge signal conditioners, thermocouple amplifiers, instrumentation amplifiers, 4 mA-to-20 mA current-loop transmitters, multiple-limit threshold detection, active filters, and multiple gain blocks. Its dual-channel configuration is useful where two related signals must be conditioned consistently, such as sensor excitation and monitoring or differential and common-reference measurements.
Designers should pay particular attention to the SOIC-8 pin mapping, supply bypass capacitors, input common-mode range, output swing, and the operating-temperature limits for this ordering code. The precision characteristics make the device useful for instrumentation, but they do not make it a universal rail-to-rail amplifier. Verify signal levels, noise requirements, load conditions, and stability requirements against the manufacturer datasheet rather than assuming that a substitute is electrically identical.
This product page consolidates the verified manufacturer and distributor information, source-backed alternatives, package details, pricing fields, application guidance, and design notes. It is intended to support initial component selection and comparison rather than replace the complete LT1013D datasheet during sign-off.

Aplikasi Biasa
LT1013DD patut untuk 6 aplikasis: Battery-Powered Precision Instrumentation, Strain-Gauge Signal Conditioning, Thermocouple Amplification, 4 mA to 20 mA Current-Loop Transmitter, Active Precision Filtering, Threshold and Limit Detection.
Battery-Powered Precision Instrumentation
The LT1013DD fits battery-powered precision measurement systems because it combines two amplifier channels, low-power characteristics, and operation from a 5 V to 44 V supply range. Two precision amplifiers can condition related inputs while keeping the analog front end compact, which is valuable when board area and standby consumption are constrained. In an instrumented sensor module, one channel can amplify a differential sensor signal while the other handles a reference, monitor, or filtering function. The selected LT1013DD supports a 0 °C to 70 °C operating range, making it appropriate for indoor commercial or industrial equipment. Actual battery performance depends on the actual supply current, sensor load, gain, duty cycle, and whether the system can disable unused channels.

Strain-Gauge Signal Conditioning
The LT1013DD is applicable to strain-gauge signal conditioning because the LT1013 family is specifically identified for strain-gauge applications. Its dual-channel architecture can support a differential amplifier arrangement and a related reference or monitor path in the same 8-pin SOIC package. The wide 5 V to 44 V supply range gives designers flexibility across laboratory, process-control, and industrial excitation systems. Designers should verify input common-mode range, offset voltage, bias current, noise, and output swing against the bridge excitation level and required gain. Starved or filtered power rails are important because the amplifier’s low-offset characteristics cannot compensate for unstable reference voltage or common-mode signals outside its specified operating region.
Disebarkan
Thermocouple Amplification
The LT1013DD can serve as a low-offset amplifier in thermocouple measurement circuits because the verified LT1013 applications include thermocouple amplifiers. The 150 µV maximum input-offset figure cited for the LT1013A family illustrates the precision orientation, although engineers must confirm the limits applicable specifically to LT1013DD. A dual package permits one amplifier to amplify the thermocouple junction voltage while the second channel supports cold-junction compensation, filtering, or monitoring. Since thermocouple signals are small and slow, offset drift and noise matter more than wide bandwidth. The design must also account for the 0 °C to 70 °C grade of this ordering code and ensure that the thermocouple loop remains within the amplifier’s specified common-mode limits.

4 mA to 20 mA Current-Loop Transmitter
The LT1013DD is relevant to 4 mA-to-20 mA current-loop transmitter signal conditioning because the LT1013 family explicitly supports this application. Its dual precision channels can be used for input conditioning and an auxiliary current-source or buffer function, helping reduce external component count. The wide 5 V to 44 V supply range is useful in industrial loops where supply voltage may vary across installed equipment. For reliable operation, the selected amplifier must remain compatible with the loop input range, sensor signal magnitude, required output compliance, and load impedance. The 0 °C to 70 °C LT1013DD grade also requires confirmation against the environmental range of industrial field equipment, where a wider-temperature option may be necessary.
Disebarkan
Active Precision Filtering
The LT1013DD can implement active filters because the verified LT1013 applications include active filters and multiple gain blocks. Precision characteristics help preserve low-level signals through cascaded stages, while the dual-channel package allows paired filter sections or independent signal paths with consistent device matching. The 5 V to 44 V supply range permits operation from conventional single-supply rails through higher-voltage instrumentation systems. Designers should determine stable gain-bandwidth and slew-rate requirements for the selected filter topology, then confirm output settling and noise performance from the manufacturer data. High-Q filters are particularly sensitive to component tolerances, so resistor and capacitor accuracy should be calculated alongside the amplifier’s offset and bias-current contributions.
Disebarkan
Threshold and Limit Detection
The LT1013DD is suitable for multiple-limit threshold detection, an application explicitly listed for the LT1013 family. Two channels can compare a control signal against upper and lower reference levels, reducing the number of packages required for window detection. The wide 5 V to 44 V supply range accommodates both low-voltage logic-adjacent measurement systems and higher-voltage industrial interfaces, provided the input and output remain within their specified limits. Precision offset behavior can improve threshold repeatability, but reference accuracy, input noise, and comparator propagation delay remain part of the total error budget. The selected ordering code’s 0 °C to 70 °C range should also be matched to the expected enclosure temperature.

Catatan Desain
Place a supply bypass capacitor close to pins 8 and 4 and route each supply connection directly to the device. The verified source identifies a 5 V to 44 V wide operating range for LT1013DD, but it does not provide the manufacturer’s recommended capacitance values. Use the LT1013D datasheet and stability guidance for the exact capacitor selection, especially when the amplifier drives cables, sensors, or capacitive loads.
Preserve the LT1013DD pin mapping shown in the datasheet: OUTA is pin 1, the two amplifier-A inputs are pins 2 and 3, V- is pin 4, the amplifier-B inputs are pins 5 and 6, OUTB is pin 7, and V+ is pin 8. Avoid interchanging the operational-amplifier pinout with the common industry-standard configuration because the verified cross-reference discussion notes that LT1013D uses a specific footprint arrangement.
Do not assume that every 8-pin dual op amp is a drop-in replacement for LT1013DD. The alternatives listed by the verified cross-reference sources share the general package class, but supply range, common-mode range, offset, noise, bias current, output swing, and stability can differ. Check every affected signal and power parameter in the candidate device datasheet and confirm the alternative’s exact ordering code and pin map.
For precision instrumentation, keep input-loop area small and avoid routing high-impedance inputs beside supply, clock, switching-converter, and digital return paths. Connect the two channels according to the required precision topology and provide a quiet ground reference appropriate to the signal source. The LT1013DD is not specified as rail-to-rail, so verify that the selected feedback network keeps inputs and outputs inside their operating limits.
Maklumat Kesediaan
The supplied verified data does not provide explicit RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive-qualification statements. The 0 °C to 70 °C commercial operating range does not by itself establish AEC-Q100 qualification.
