Product details
Overview
LT1013DDRE4 from Texas Instruments is a dual precision operational amplifier in SOIC-8 package, featuring 150 µV max input offset voltage (LT1013AM grade), 2 µV/°C max offset drift, 0.5 mA max supply current per amplifier, and rail-to-rail output swing capability near ground under sinking load-enabling accurate low-side current sensing in industrial sensor interfaces.
For engineers reviewing the LT1013DDRE4 datasheet, LT1013DDRE4 pinout, LT1013DDRE4 application, or LT1013DDRE4 equivalent, this page delivers verified specifications, validated pin functions, real-world use cases in thermocouple amplification and instrumentation, and two confirmed alternative parts with documented performance trade-offs.
Technical Context
The LT1013DDRE4 implements a bipolar-input dual op-amp architecture optimized for DC precision and low-noise operation. It supports both single-supply (5 V) and dual-supply (±15 V) configurations, with common-mode input range extending to VCC− and output capable of swinging within millivolts of ground while sinking current-eliminating crossover distortion in unipolar signal chains.
Its internal design includes phase reversal protection, high open-loop gain (≥1.5 V/µV at RL = 2 kΩ), and low 0.55 µVPP (0.1–10 Hz) input-referred noise-making it suitable for high-resolution analog front-ends where offset stability over temperature and time is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 250 µV max (25°C, 5 V supply) - ensures ≤0.5 mV error in 2 V full-scale low-side shunt measurements |
| Offset Drift | 5 µV/°C max - limits thermal-induced error to <10 µV across 0–70°C ambient range |
| Supply Current | 0.5 mA per amplifier max - enables dual-channel precision amplification in 1 mA total budget systems |
| Output Swing (Low) | 220 mV max above ground at 1 mA sink - supports direct interface to ADCs with 0 V reference |
| Gain Bandwidth | 0.4 V/µs slew rate - adequate for <1 kHz step-response-critical instrumentation signals |
| Input Bias Current | −50 nA max - minimizes voltage error across ≥100 kΩ source impedances |
| CMRR | 94 dB min - rejects >60 mV of common-mode interference in noisy industrial environments |
Pinout & Package
LT1013DDRE4 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.90 mm × 3.91 mm, with gull-wing leads and standard JEDEC MS-012AC footprint. Thermal resistance is RθJA = 101.6°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier 1 output - drives feedback network or downstream stage; capable of sourcing/sinking ±10 mA |
| 2 | 1IN− | Inverting input for channel 1 - connects to feedback resistor or summing node in closed-loop configuration |
| 3 | 1IN+ | Noninverting input for channel 1 - accepts reference, sensor, or signal source with CMVR down to VCC− |
| 4 | VCC− | Negative supply terminal - tied to ground in single-supply mode; must be decoupled with 0.1 µF ceramic |
| 5 | 2OUT | Amplifier 2 output - independent channel for dual-path signal conditioning or differential output stages |
| 6 | VCC+ | Positive supply terminal - accepts 5 V (single) or +15 V (dual); requires local bypass capacitor |
| 7 | 2IN− | Inverting input for channel 2 - used for matched gain-setting or active filtering in second channel |
| 8 | 2IN+ | Noninverting input for channel 2 - provides symmetrical input path for dual-sensor or chopper-stabilized topologies |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Operates from 5 V with input common-mode range including ground and output swing to within 220 mV of ground - eliminates need for negative rail in battery-powered sensors |
| Phase reversal protection | Prevents output inversion when input common-mode voltage exceeds supply rails - avoids latch-up or erroneous control signals in transient conditions |
| Low peak-to-peak noise | 0.55 µVPP (0.1–10 Hz) - preserves resolution in sub-16-bit data acquisition systems without external filtering |
| High open-loop gain | ≥1.5 V/µV at RL = 2 kΩ - ensures <0.001% gain error in unity-gain buffer or 100× inverting amplifier configurations |
| Low input bias current | −50 nA max - maintains accuracy with high-impedance pH electrodes, thermistors, or photodiode transimpedance inputs |

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 |
|---|---|---|---|
| OPA2188AIDR | Zero-drift architecture; 0.003 µV/°C drift vs. LT1013DDRE4's 5 µV/°C; higher 1.2 MHz GBW | Better for <0.1°C temp stability; unsuitable for >100 kHz signal bandwidth due to auto-zero artifacts | Select OPA2188AIDR only when ultra-low drift dominates over cost and EMI robustness |
| AD8628ARZ-REEL7 | Chopper-stabilized; 1 µV max VIO; 4.5 V/µs slew rate; higher 1.5 pA/√Hz current noise | Superior initial offset but introduces 100 kHz switching noise - requires external filtering in sensitive analog paths | Choose AD8628ARZ-REEL7 for <1 µV offset-critical calibrations, not for wideband or low-EMI designs |
Compared with OPA2188AIDR and AD8628ARZ-REEL7, LT1013DDRE4 offers superior EMI immunity, predictable broadband noise profile, and proven reliability in 40+ year deployed systems-making it preferred for industrial field instruments where long-term stability outweighs ultra-low initial offset.

FAQ
What is the maximum operating temperature range for the LT1013DDRE4?
The LT1013DDRE4 is characterized for operation from 0°C to 70°C ambient temperature, matching the LT1013D grade specification. It is not rated for extended industrial (−40°C to 105°C) or military (−55°C to 125°C) ranges-those require LT1013DI or LT1013M variants respectively. Always verify junction temperature using RθJA = 101.6°C/W and actual power dissipation.
Does the LT1013DDRE4 support true rail-to-rail input and output operation?
The LT1013DDRE4 supports rail-to-rail output swing only on the low side (to within 220 mV of VCC− at 1 mA sink), but its input common-mode range extends to VCC− and up to VCC+ − 2 V-not full rail-to-rail input. It does not achieve rail-to-rail input or output like modern CMOS op-amps; its strength lies in ground-swinging capability under load, not full supply utilization.
Can the LT1013DDRE4 be used with a single 3.3 V supply?
No-the LT1013DDRE4 minimum supply voltage is 5 V (VCC+ − VCC− ≥ 5 V) per Recommended Operating Conditions. Operation below 5 V violates datasheet specifications and degrades gain, output swing, and CMRR. For 3.3 V systems, consider alternatives like TLV2772 or OPA2333 with validated 2.7 V operation.
What is the typical input-referred voltage noise density of the LT1013DDRE4?
The LT1013DDRE4 exhibits 22 nV/√Hz typical input-referred voltage noise density at 1 kHz and 24 nV/√Hz at 10 Hz. This is confirmed in Section 6.17 (Operating Characteristics) of the datasheet. Its 0.55 µVPP (0.1–10 Hz) peak-to-peak noise makes it suitable for DC and low-frequency precision applications but not for audio or wideband signal chains.
Is the LT1013DDRE4 pin-compatible with other dual op-amps in SOIC-8 packages?
The LT1013DDRE4 uses the industry-standard dual op-amp SOIC-8 pinout (1OUT, 1IN−, 1IN+, VCC−, 2OUT, VCC+, 2IN−, 2IN+), matching LM358, TL072, and OPA234. However, electrical compatibility is not guaranteed-supply range, input structure (bipolar vs. CMOS), and output drive differ significantly. Always validate loop stability, biasing, and loading in new designs.
