Product details
Overview
LT1013DIPG4 from Texas Instruments is a dual precision operational amplifier in an 8-pin PDIP package, featuring 200 µV max input offset voltage (25°C), 0.5 mA max supply current per amplifier, and rail-to-rail output swing capability down to ground under sinking load. It operates from single 5-V or dual ±15-V supplies and is used in low-side current sensing circuits where ground-referenced input and output are required.
For engineers reviewing the LT1013DIPG4 datasheet, LT1013DIPG4 pinout, LT1013DIPG4 application, or LT1013DIPG4 equivalent, this page delivers verified specifications, validated pin functions, real-world use cases in instrumentation and thermocouple amplification, and confirmed alternative parts with documented parameter differences.
Technical Context
The LT1013DIPG4 integrates two independent high-gain, low-noise op-amp channels sharing a common supply domain. Its input stage supports common-mode voltage down to VCC− (ground in single-supply mode), and its output stage drives to within millivolts of VCC− while sinking current - enabling true single-supply operation without level-shifting circuitry.
It features phase reversal protection, 0.55 µVPP (0.1–10 Hz) input noise, and 0.07 pA/√Hz current noise. The device is characterized for 0°C to 70°C ambient operation and meets JEDEC HBM ±1000 V and CDM ±500 V ESD ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 200 µV max at 25°C - ensures ≤0.5 mV error in 2.5 V full-scale differential measurements |
| Supply Current per Amplifier | 0.5 mA max at 25°C - enables dual-channel precision amplification in <1 mA total supply budget |
| Input Bias Current | –30 nA max at 25°C - minimizes voltage error across ≥100 kΩ source impedances |
| Common-Mode Input Range | 0 V to 3.5 V (5 V supply) - allows direct connection to ground-referenced sensors like shunt resistors |
| Output Swing (Low) | 220 mV max at 1 mA sink (25°C) - supports accurate low-voltage signal reconstruction near ground |
| Gain Bandwidth Product | 0.4 V/µs slew rate - sufficient for DC–1 kHz closed-loop applications including thermocouple conditioning |
| Equivalent Input Noise | 0.55 µVPP (0.1–10 Hz) - critical for stable DC-coupled measurement of microvolt-level sensor outputs |
Pinout & Package
LT1013DIPG4 uses an 8-pin plastic dual in-line package (PDIP) with 9.81 mm × 6.35 mm body size and 0.1 inch lead pitch. Pin 1 is located at the left end of the top row when viewed from top with notch or dot oriented left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of amplifier channel 1 - drives external load or feedback network |
| 2 | 1IN− | Inverting input of channel 1 - accepts feedback or inverted signal path |
| 3 | 1IN+ | Noninverting input of channel 1 - connects to reference or sensor signal |
| 4 | VCC− | Negative supply terminal - tied to ground in single-supply configurations |
| 5 | 2OUT | Output of amplifier channel 2 - independent output for second signal path |
| 6 | VCC+ | Positive supply terminal - accepts 5 V (single) or +15 V (dual supply) |
| 7 | 2IN− | Inverting input of channel 2 - supports dual-channel instrumentation topologies |
| 8 | 2IN+ | Noninverting input of channel 2 - enables simultaneous dual-sensor conditioning |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Input common-mode range includes ground and output swings to ground - eliminates need for negative rail in low-voltage systems |
| Phase reversal protection | Prevents output latch-up during input overvoltage beyond rails - improves reliability in noisy industrial environments |
| Low peak-to-peak noise | 0.55 µVPP (0.1–10 Hz) - enables stable DC amplification of thermocouple and strain gauge signals |
| Low input offset drift | 5 µV/°C max temperature coefficient - maintains accuracy across 0°C to 70°C operating range without recalibration |
| High CMRR | 94 dB min over full temperature range - rejects common-mode interference in unshielded sensor wiring |
Applications
| Thermocouple Amplifiers | Low-Side Current Measurement |
|---|---|

IC Role / Device Role / Timing Role: Single-supply difference amplifier measuring voltage drop across low-side shunt, referenced to system ground. Use Value: Input range extending to ground allows direct connection to shunt; 220 mV max output low enables accurate 0–100 mV signal capture. |
| Instrumentation Amplifiers | Medical Sensor Signal Conditioning |
|
Use Scenario: Building 3-op-amp instrumentation amplifier for ECG electrode signal extraction in portable monitors. IC Role / Device Role / Timing Role: Dual-channel core providing matched gain stages for input buffers and output stage. Use Value: Channel separation >120 dB prevents crosstalk between differential inputs; 0.07 pA/√Hz current noise preserves high-impedance electrode interface integrity. |
Use Scenario: Amplifying pH probe output (±400 mV, high impedance) in point-of-care blood analyzers. IC Role / Device Role / Timing Role: First-stage buffer and gain amplifier with ultra-low bias current to avoid probe polarization errors. Use Value: 0.3 nA max IIO limits voltage error to <30 µV across 100 MΩ probe impedance - preserving measurement fidelity. |
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 VIO (25 µV typ), higher slew rate (2.8 V/µs), but no single-supply rail-to-ground output capability | Requires dual ±15-V supply; unsuitable for ground-sensing shunt amplifiers | Select OP27GP only when high-speed AC performance and ultra-low offset outweigh single-supply constraints |
| TL082CP | Higher VIO (10 mV max), higher noise (18 nV/√Hz), but same PDIP-8 package and pinout | Acceptable for non-precision AC-coupled applications; not suitable for DC thermocouple or medical sensor use | Choose TL082CP for cost-sensitive, non-critical analog stages where precision and noise are secondary |
Compared with OP27GP and TL082CP, the LT1013DIPG4 uniquely balances single-supply usability, sub-millivolt DC accuracy, and microvolt-level noise - making it irreplaceable in ground-referenced precision DC measurement where supply simplicity and long-term stability are mandatory.

FAQ
What is the maximum operating temperature range for the LT1013DIPG4?
The LT1013DIPG4 is characterized for operation from 0°C to 70°C ambient temperature. This commercial-grade rating is specified in the device's Recommended Operating Conditions table and applies to all electrical parameters unless otherwise noted. The LT1013DIPG4 is not rated for extended industrial (–40°C to 105°C) or military (–55°C to 125°C) temperature ranges - those require LT1013DI or LT1013M variants respectively.
Does the LT1013DIPG4 support true single-supply operation with input and output referenced to ground?
Yes, the LT1013DIPG4 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 220 mV of ground while sinking 1 mA. This enables direct interfacing with ground-referenced sensors like shunt resistors and thermocouples without level-shifting circuitry - a key differentiator from many legacy op-amps.
What is the typical input-referred voltage noise of the LT1013DIPG4 at 1 kHz?
The LT1013DIPG4 has a typical equivalent input noise voltage of 22 nV/√Hz at 1 kHz, as specified in the Operating Characteristics table. This value is measured under standard conditions (VCC± = ±15 V, TA = 25°C) and reflects the device's suitability for low-frequency precision applications where wideband noise is not dominant - such as DC-coupled sensor signal conditioning.
Can the LT1013DIPG4 be used in place of the LT1013D or LT1013P?
Yes - LT1013DIPG4 is the TI-specified orderable part number for the LT1013D device in PDIP-8 packaging. It is functionally identical to LT1013D and LT1013P (both denote the same commercial-grade dual op-amp in PDIP), with "G4" indicating RoHS-compliant green packaging. No electrical or functional differences exist between these designations; they reflect packaging and compliance variants of the same silicon.
What is the minimum recommended load resistance for stable operation of the LT1013DIPG4?
The LT1013DIPG4 is specified with load resistances down to 600 Ω in its Electrical Characteristics tables (e.g., AVD test condition). While not explicitly stated as a minimum, stable operation is confirmed for RL ≥ 600 Ω across all supply and temperature conditions. Driving lower loads may degrade gain accuracy and increase output distortion - use external buffers if driving <600 Ω loads is required.
