LT1013DP 概述
What is a precision operational amplifier? A precision op amp is a voltage-feedback amplifier used to amplify small differential signals while controlling offset, bias current, drift, and output behavior. Within the signal-chain hierarchy, the LT1013DP is a dual amplifier IC that can serve as an instrumentation amplifier building block, a buffer, an active-filter element, or a precision gain stage. Its dual channel count allows two signal paths or a differential signal-conditioning structure in one package.
Key verified features include a 4 V to 44 V supply range, dual precision operation, and the industry-standard 8-pin configuration identified by Analog Devices as the first precision dual op amp in that configuration. The LT1013DP is listed by DigiKey as a two-circuit, 8-PDIP amplifier. The Analog Devices product page specifically identifies 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 as application areas.
The LT1013DP is especially relevant where a low-power amplifier must operate across a broad supply range or support single-supply signal paths whose input and output approach ground. Compared with a conventional dual precision amplifier in a different package, its 8-PDIP format favors through-hole prototyping, educational platforms, legacy industrial equipment, and repair assemblies where pin compatibility and mechanical replacement matter. The product family is not limited to ±15 V operation; the verified product description confirms single 5 V operation as well.
The principal design trade-off is that a PDIP package is larger and less suitable for high-density surface-mount assemblies than a modern small-outline package. Designers should still verify the exact ordering variant, pinout, common-mode limits, output swing, input bias current, offset voltage, drift, noise, and supply-current limits against the manufacturer datasheet before production release. The verified product family is described as low power, but the precise quiescent-current value is not supplied in the provided web data and should be treated as .
This page synthesizes the verified LT1013 family descriptions, distributor identification, package information, application references, and cross-reference search results. It distinguishes exact verified facts from parameters that require the full manufacturer datasheet, helping engineers evaluate the LT1013DP for precision instrumentation, bridge sensing, thermocouple signal conditioning, current-loop transmission, filtering, and legacy through-hole amplifier designs.

典型应用
LT1013DP 适用于 6 应用s: Battery-Powered Precision Instrumentation, Strain-Gauge Signal Conditioning, Thermocouple Amplifier, 4-20 mA Current-Loop Transmitter, Precision Active Filter, Precision Gain Block.
Battery-Powered Precision Instrumentation
The LT1013DP fits battery-powered precision instrumentation because the LT1013 family combines a dual precision amplifier configuration with a verified 4 V to 44 V supply range and is explicitly identified as low power. The device can amplify low-level sensor signals while the instrumentation system operates from a single 5 V supply. Single-supply operation is especially useful when the signal remains within the verified input and output behavior near ground. The designer must still check offset voltage, input bias current, common-mode limits, quiescent current, and output loading against the exact manufacturer datasheet.
推荐
Strain-Gauge Signal Conditioning
Strain-gauge conditioning is an explicitly listed LT1013 application, making the LT1013DP suitable for bridge-amplifier front ends where small differential signals must be amplified accurately. Its dual precision architecture can support a gain stage or instrumentation-amplifier arrangement while operating from the verified 4 V to 44 V family supply range. The principal design checks are input offset, bias-current error, common-mode range, output swing, bridge excitation noise, and grounding. The supplied data does not quantify those detailed limits, so the exact grade datasheet is required before calibration.
推荐
Thermocouple Amplifier
The LT1013DP is suitable for thermocouple signal conditioning because thermocouple amplifiers are explicitly included in the Analog Devices LT1013 application list. The amplifier can provide a low-level gain stage before digitization or control circuitry, while the wide family supply range supports instrumentation systems with different supply choices. Designers should account for microvolt-class input errors, cold-junction compensation, input protection, common-mode limits, and output settling. Those numerical performance requirements are not fully supplied in the verified data and must be checked in the manufacturer documentation.
推荐
4-20 mA Current-Loop Transmitter
For 4 mA to 20 mA current-loop transmitter designs, the LT1013DP provides two precision amplifier channels in the verified 8-PDIP package. The dual configuration can support signal conditioning and active stages around a transmitter front end, while the LT1013 family's 4 V to 44 V supply range is useful for industrial instrumentation. The circuit must maintain loop compliance, protect the input from wiring transients, and avoid amplifier saturation when the sensor approaches an endpoint. Verify common-mode range, output current, and slew behavior against the exact datasheet.
推荐
Precision Active Filter
The LT1013DP can participate in precision active-filter circuits because the Analog Devices product page explicitly identifies active filters and multiple-gain blocks as LT1013 applications. Its dual channel arrangement allows two filter stages or a gain-and-filter combination in one package, reducing board space relative to two separate amplifiers. The design must confirm gain-bandwidth product, slew rate, output loading, noise, and stability for the intended cutoff and Q. Since those values are [DATA_NEEDED: gain bandwidth product] and [DATA_NEEDED: slew rate] in the supplied data, engineers should use the exact manufacturer electrical table.
推荐
Precision Gain Block
The LT1013DP is suitable for precision gain blocks because the LT1013 family is described as a dual precision operational amplifier and the Analog Devices application list includes multiple gain blocks. The through-hole 8-PDIP format is useful for prototypes, educational instruments, and legacy equipment where a compact surface-mount package would be mechanically inconvenient. In practice, resistor accuracy, input bias current, offset drift, output swing, and load capability determine the achievable gain accuracy. Review those parameters with the exact datasheet and test the complete gain network at the intended supply voltage.

设计说明
For precision gain and instrumentation circuits, keep the non-inverting and inverting input traces short and pair them with a stable ground reference. The verified LT1013DP identity supports dual precision operation and a single-supply signal path, but the supplied data does not state offset, bias-current, common-mode, or noise limits. Before finalizing resistor values, verify those parameters and calculate the resulting error budget for the intended gain.
Choose the supply rails and input/output operating points from the verified 4 V to 44 V family range, not from the package name alone. The Analog Devices documentation explicitly covers ±15 V and single 5 V applications, while the verified family description also notes single-supply operation extending to ground. Confirm common-mode range, output swing, load current, and supply-current limits in the exact LT1013DP datasheet before connecting sensor or bridge circuits.
The 8-pin PDIP format is intended for through-hole assembly, so preserve adequate spacing around the package and route sensitive input traces away from switching regulators, relays, and high-current return paths. Use short feedback connections and a clean ground reference to reduce pickup and ground-potential error. The supplied web data does not contain a manufacturer-recommended land pattern or layout drawing, so verify the exact package drawing before fabrication.
合规信息
The supplied verified data identifies the manufacturer, product family, package, distributor listing, price, and applications, but it does not provide RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification data. Compliance status must be confirmed from current manufacturer documentation.
