Product details
Overview
LT1013MDREP from Texas Instruments is a dual precision operational amplifier engineered for high-accuracy analog signal conditioning in military-temperature-range applications (−55°C to 125°C). It delivers 150 µV max input offset voltage at 25°C, 2 µV/°C max offset drift, 0.8 nA max input offset current, 1.5 V/µV min open-loop gain (RL = 2 kΩ), and 0.5 mA max supply current per amplifier - enabling stable low-side current sensing and thermocouple amplification in harsh environments.
For engineers reviewing the LT1013MDREP datasheet, LT1013MDREP pinout, LT1013MDREP application, or LT1013MDREP equivalent, this page provides verified specifications, military-grade thermal and electrical performance data, SOIC-8 package mapping, and validated alternatives for precision analog designs requiring guaranteed operation across −55°C to 125°C.
Technical Context
The LT1013MDREP implements a bipolar-input, internally compensated op-amp architecture optimized for DC precision and low-noise AC performance. Its input stage supports rail-to-rail common-mode range down to ground on single 5-V supplies and extends to ±15 V with full differential input voltage tolerance of ±30 V.
It features phase reversal protection, crossover distortion elimination, and output swing within millivolts of ground while sinking current - critical for unidirectional sensor interfaces and instrumentation amplifier front-ends operating under wide supply and temperature variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 150 µV max at 25°C - ensures ≤0.015% gain error in 10-V full-scale precision measurement circuits |
| Offset Tempco | 2 µV/°C max - limits drift to ≤250 µV over full −55°C to 125°C range, enabling stable calibration |
| Input Offset Current | 0.8 nA max at 25°C - minimizes voltage error across high-impedance sources (e.g., thermocouples, pH electrodes) |
| Open-Loop Gain | 1.5 V/µV min (RL = 2 kΩ) - supports ≥120 dB loop gain in unity-gain-stable configurations |
| Supply Current | 0.5 mA max per amplifier - enables dual-channel precision amplification within 1 mA total budget |
| Input Noise | 0.55 µV p-p (0.1–10 Hz), 22 nV/√Hz @ 1 kHz - preserves SNR in sub-mV sensor signal chains |
| Operating Temp | −55°C to 125°C - qualified per MIL-PRF-38535 for aerospace, defense, and downhole industrial systems |
Pinout & Package
LT1013MDREP is housed in an 8-pin SOIC package (body size 4.90 mm × 3.91 mm) with standard dual-op-amp pinout and no internal connections on pins 4 and 5 (VCC− and 2OUT are functional; pin 4 is VCC−, pin 5 is 2OUT).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier 1 output - drives feedback networks or downstream ADC drivers with rail-to-rail swing capability |
| 2 | 1IN− | Inverting input for channel 1 - accepts differential or single-ended signals with 4 GΩ common-mode input resistance |
| 3 | 1IN+ | Noninverting input for channel 1 - supports ground-referenced inputs and low-side current sensing topologies |
| 4 | VCC− | Negative supply terminal - must be connected to system ground on single-supply operation (0 V) |
| 5 | 2OUT | Amplifier 2 output - independent channel enables dual-stage filtering or matched gain paths |
| 6 | VCC+ | Positive supply terminal - operates from 5 V to 30 V total supply range (VCC+ − VCC−) |
| 7 | 2IN− | Inverting input for channel 2 - electrically isolated from channel 1; supports separate sensor inputs |
| 8 | 2IN+ | Noninverting input for channel 2 - identical DC specs to channel 1; enables matched dual-channel instrumentation |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Input common-mode range includes ground; output swings to ground while sinking current - eliminates level-shifting in 5-V microcontroller-based systems |
| Phase reversal protection | Prevents output latch-up during input overvoltage - critical for robustness in noisy industrial I/O modules |
| Military temperature qualification | Tested and characterized from −55°C to 125°C per MIL-PRF-38535 - guarantees parametric compliance without derating |
| Low peak-to-peak noise | 0.55 µV p-p (0.1–10 Hz) - enables resolution of <1 µV DC signals in thermopile and strain gauge amplifiers |
| High CMRR & PSRR | ≥97 dB CMRR and ≥100 dB PSRR - suppresses power supply ripple and common-mode interference in precision bridges |
Applications
| Thermocouple Amplifiers | Low-Side Current Measurement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP27GP | Higher speed (2.8 V/µs slew), lower noise (3.5 nV/√Hz), but wider VIO spec (25 µV typ, not max) and only commercial temp range (0°C to 70°C) | Not qualified for −55°C to 125°C operation; unsuitable for military/aerospace deployments | Select OP27GP only for cost-sensitive commercial systems where speed outweighs temperature stability requirements |
| LM158J | Wider VIO (3 mV max), higher supply current (1.2 mA max), and lower gain (25 V/mV) - but same military temp rating and CDIP-8 package | Lower precision and higher power consumption limit use to non-critical biasing or comparator functions | Choose LM158J when legacy footprint compatibility and extreme ruggedness are prioritized over DC accuracy |
Compared with OP27GP and LM158J, LT1013MDREP uniquely balances military-temperature operation, 150 µV max VIO, and 0.5 mA supply current - making it the only option among the three that meets both precision and extended-temperature requirements simultaneously.

FAQ
What is the maximum input offset voltage specification for LT1013MDREP at 25°C?
The LT1013MDREP has a maximum input offset voltage of 150 µV at 25°C, as specified in the Electrical Characteristics table for LT1013AM-grade devices under ±15 V supply conditions. This value is guaranteed across all units and forms the basis for its classification as a precision op-amp suitable for high-accuracy measurement applications.
Does LT1013MDREP support single-supply operation with ground-referenced inputs?
Yes, LT1013MDREP supports true single-supply operation: its input common-mode voltage range extends to VCC− (ground when VCC− = 0 V), and its output can swing to within millivolts of ground while sinking current. This allows direct interfacing with grounded shunt resistors and thermocouple cold junctions without external level-shifting circuitry.
What temperature range is LT1013MDREP qualified for, and what standard applies?
LT1013MDREP is characterized and tested over the full military temperature range of −55°C to 125°C, compliant with MIL-PRF-38535 Class B requirements. This qualification ensures guaranteed parametric performance and reliability in aerospace, defense, and industrial systems exposed to extreme thermal environments.
What is the supply current consumption of LT1013MDREP per amplifier?
The LT1013MDREP consumes a maximum of 0.5 mA per amplifier at TA = 25°C, as specified in the Electrical Characteristics section for LT1013AM devices. Total device supply current is therefore ≤1.0 mA - enabling dual-channel precision amplification within tight power budgets typical of battery-backed or thermally constrained systems.
Is LT1013MDREP pin-compatible with other packages in the LT1013 family?
LT1013MDREP uses the SOIC-8 package (D package), which shares the same pinout as LT1013D and LT1013C in SOIC-8. It is not pin-compatible with CDIP-8 (JG), PDIP-8 (P), or LCCC-20 (FK) variants due to differing pin counts and layouts - board redesign is required when migrating between these packages.
