Product details
Overview
LT1013CPE4 from Texas Instruments is a dual precision operational amplifier in an 8-pin PDIP package, featuring 150 µV max input offset voltage (25°C), 2 µV/°C max offset drift, 0.5 mA max supply current per amplifier, rail-to-rail output swing capability near ground under sinking load, and phase reversal protection - used in thermocouple amplifiers, low-side current sensing, and instrumentation amplifier front-ends.
For engineers reviewing the LT1013CPE4 datasheet, LT1013CPE4 pinout, LT1013CPE4 application, or LT1013CPE4 equivalent, this page delivers verified specifications, validated pin functions, real-world use cases for precision analog signal conditioning, and confirmed alternative options for dual op-amp designs requiring low offset, single-supply compatibility, and military-grade temperature stability.
Technical Context
The LT1013CPE4 implements a bipolar-input, internally compensated dual op-amp architecture optimized for precision DC performance. Its input stage supports common-mode voltage down to VCC− (ground in single-supply mode), and its output stage drives within millivolts of ground while sinking current - enabling true single-supply operation without level-shifting circuitry.
It features phase reversal protection to prevent output inversion during input overdrive, and achieves high open-loop gain (≥1.2 V/µV at RL = 2 kΩ) with low 0.55 µVPP (0.1–10 Hz) input-referred noise. The device operates across 0°C to 70°C ambient temperature and supports ±15 V dual or +5 V single supply configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 150 µV max at 25°C - ensures ≤0.15 mV DC error in unity-gain buffer or differential amplifier configurations. |
| Offset Drift | 2 µV/°C max - limits thermal-induced error to <10 µV over 50°C ambient shift, critical for stable sensor interfaces. |
| Supply Current | 0.5 mA max per amplifier - enables low-power operation in battery-backed instrumentation or portable test equipment. |
| Output Swing (to Ground) | 220–350 mV at 1 mA sink - allows direct interfacing with 0 V–5 V ADC references and logic-level comparators. |
| Open-Loop Gain | 1.2 V/µV min (RL = 2 kΩ) - provides ≥120 dB loop gain for high-accuracy closed-loop gains up to 1000. |
| Input Bias Current | −30 nA max - minimizes voltage error across high-impedance sources like thermocouples or pH electrodes. |
| CMRR | 94 dB min - rejects >99.99% of common-mode noise in bridge-based transducer circuits. |
Pinout & Package
LT1013CPE4 uses an 8-pin plastic dual in-line package (PDIP), 9.81 mm × 6.35 mm body size, with through-hole mounting and industry-standard pin spacing (0.1 inch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of amplifier channel 1 - drives external loads, feedback networks, or ADC inputs with rail-to-ground swing. |
| 2 | 1IN− | Inverting input of channel 1 - connects to feedback resistor in inverting configuration or to reference in differential setups. |
| 3 | 1IN+ | Noninverting input of channel 1 - accepts sensor signals, reference voltages, or buffered inputs with full common-mode range to ground. |
| 4 | VCC− | Negative supply terminal - tied to ground in single-supply mode; enables true zero-input-voltage operation. |
| 5 | 2OUT | Output of amplifier channel 2 - independent output for second signal path, e.g., reference buffer or dual-channel sensor conditioning. |
| 6 | VCC+ | Positive supply terminal - accepts +5 V (single) or +15 V (dual); supports wide supply range (5 V to 30 V total). |
| 7 | 2IN− | Inverting input of channel 2 - used for matched gain-setting or common-mode rejection in instrumentation topologies. |
| 8 | 2IN+ | Noninverting input of channel 2 - pairs with 2IN− to form second precision gain stage or active filter section. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Input common-mode range extends to VCC− (ground); output swings to within 350 mV of ground while sinking 1 mA - eliminates need for negative rail in 0–5 V systems. |
| Phase reversal protection | Prevents output inversion when input common-mode voltage exceeds supply rails - avoids latch-up or erroneous control signals in overvoltage fault conditions. |
| Low peak-to-peak noise | 0.55 µVPP (0.1–10 Hz) - enables sub-16-bit resolution in low-frequency sensor digitization without external filtering. |
| High CMRR & PSRR | 94 dB CMRR min, 97 dB PSRR min - maintains accuracy in noisy industrial environments with shared power/ground paths. |
| Stable over temperature | Specified for 0°C to 70°C operation with guaranteed 150 µV VIO and 2 µV/°C drift - supports calibration-free operation in commercial-grade embedded systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP27GP | Lower 0.1 µV/°C drift and 25 µV max VIO, but requires dual ±15 V supply and lacks single-supply ground-swing capability. | Better for lab-grade instruments with dual supplies; unsuitable for 5 V-only systems needing ground-referenced output. | Select OP27GP only if ultra-low drift dominates over supply flexibility and cost. |
| LM358N | Higher 2 mV max VIO, no phase reversal protection, 700 kHz GBW vs LT1013CPE4's 1 MHz, but lower cost and wider availability. | Acceptable for non-critical consumer applications; insufficient for thermocouple or precision current sensing where <100 µV error is required. | Choose LM358N only for cost-sensitive, non-precision designs where 0.1% accuracy is not mandatory. |
Compared with OP27GP and LM358N, LT1013CPE4 uniquely balances low offset (150 µV), ground-swing output, phase reversal immunity, and 0°C–70°C commercial qualification - making it optimal for industrial sensor interfaces where single-supply operation and DC precision coexist.

FAQ
What is the maximum operating temperature range for the LT1013CPE4?
The LT1013CPE4 is characterized for operation from 0°C to 70°C ambient temperature. This commercial-grade specification ensures guaranteed performance in office, laboratory, and factory-floor environments where thermal management is moderate. It does not meet extended or military temperature requirements - those are covered by LT1013M or LT1013AM variants. The LT1013CPE4 remains fully functional within this range without derating.
Does the LT1013CPE4 support true single-supply operation with input and output referenced to ground?
Yes, the LT1013CPE4 supports true single-supply operation: its input common-mode voltage range extends to VCC− (ground), and its output can swing to within 220–350 mV of ground while sinking 1 mA. This enables direct interfacing with 0 V–5 V ADCs and microcontrollers without level-shifting circuitry - a key advantage over older op-amps that require dual supplies for ground-referenced signals.
What is the typical input-referred noise performance of the LT1013CPE4?
The LT1013CPE4 delivers 0.55 µVPP (0.1–10 Hz) peak-to-peak input-referred noise and 22 nV/√Hz at 1 kHz. This low noise floor supports high-resolution digitization of low-level sensor signals such as thermocouples or bridge outputs without requiring additional filtering stages - preserving signal integrity and simplifying PCB layout in precision analog front-ends.
Is the LT1013CPE4 pin-compatible with other packages in the LT1013x family?
No - the LT1013CPE4 uses an 8-pin PDIP (P package), while LT1013D variants use SOIC-8 and LT1013M/AM variants use CDIP-8 or LCCC-20. Pinout is identical across all 8-pin versions (P, D, JG), but physical dimensions, thermal resistance, and soldering methods differ. Board redesign is required when substituting PDIP with SOIC or LCCC packages due to footprint and reflow profile incompatibility.
How does phase reversal protection function in the LT1013CPE4?
Phase reversal protection in the LT1013CPE4 prevents output inversion when either input exceeds the supply rails - a failure mode common in bipolar op-amps under overvoltage or ESD stress. This internal circuitry ensures the output remains predictable and does not latch or oscillate, maintaining system safety in industrial sensor interfaces where transient overvoltages may occur on unshielded lines.
