Product details
Overview
LT1014DING4 from Texas Instruments is a quad precision operational amplifier in 14-pin plastic DIP (N) package, designed for single- and dual-supply operation (±15 V or +5 V/0 V). It delivers 300 µV max input offset voltage at 25°C, 2.5 µV/°C max offset drift, 1.2 V/µV min large-signal gain (RL = 2 kΩ), 2.2 mA max total supply current, and 0.55 µV peak-to-peak input noise (0.1–10 Hz). It enables precision signal conditioning in industrial sensor front-ends requiring rail-to-rail input and ground-swinging output.
For engineers reviewing the LT1014DING4 datasheet, LT1014DING4 pinout, LT1014DING4 application, or LT1014DING4 equivalent, this page provides verified electrical specifications, thermal performance across −40°C to 105°C, single-supply phase-reversal immunity, low-noise design context, and validated alternatives for analog signal chain upgrades.
Technical Context
The LT1014DING4 integrates four independent high-gain amplifiers with all-NPN output stages enabling true ground-swinging output (≤13 mV above GND at 1 mA sink) and common-mode input range extending to ground - critical for single-supply instrumentation. Its internal 400-Ω series input resistors and dedicated phase-reversal protection circuitry (Q21–Q28) prevent destructive latch-up and output inversion when inputs dip to −1.5 V.
It operates over −40°C to 105°C with guaranteed 300 µV max VIO and 2.5 µV/°C max TCVO at 25°C, supported by 70 MΩ min differential input resistance and 4 GΩ common-mode input resistance. The architecture eliminates crossover distortion in dual-supply mode and maintains >94 dB CMRR across full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 300 µV max at 25°C - ensures ≤0.3 mV DC error in 1× gain configurations without trimming. |
| Offset Drift | 2.5 µV/°C max - limits thermal-induced error to <25 µV over 10°C ambient shift. |
| Large-Signal Gain | 1.2 V/µV min (RL = 2 kΩ) - supports ≥120 dB open-loop gain for stable closed-loop precision filtering. |
| Supply Current | 2.2 mA max total (550 µA per amp) - enables low-power multi-channel sensing with minimal thermal load. |
| Output Swing (Single-Supply) | ≤13 mV above GND at 1 mA sink - allows direct interfacing with 0-V referenced ADCs or logic. |
| Input Noise (0.1–10 Hz) | 0.55 µV p-p - suitable for sub-100 nV/√Hz applications like strain gauge or thermopile amplification. |
| Common-Mode Range | Includes ground (0 V) on single +5 V supply - eliminates need for level-shifting bias networks. |
Pinout & Package
LT1014DING4 uses a 14-pin plastic DIP (N) package with industry-standard pinout. Pin 1 is 1OUT; pins 2 and 3 are 1IN− and 1IN+; pin 4 is VCC+; pins 5 and 6 are 2IN+ and 2IN−; pin 7 is 2OUT; pin 8 is NC; pin 9 is 4OUT; pins 10 and 11 are 4IN− and 4IN+; pin 12 is VCC−/GND; pins 13 and 14 are 3IN+ and 3IN−; pin 15 is 3OUT; pin 16 is NC (note: N package has 14 pins - pins 15/16 do not exist; J/N pinout matches schematic labeling).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 9, 15 | Amplifier Output (1OUT, 2OUT, 4OUT, 3OUT) | Low-impedance NPN emitter-follower output capable of sinking ≥1 mA to GND while maintaining linearity. |
| 2, 6, 10, 14 | Inverting Input (1IN−, 2IN−, 4IN−, 3IN−) | Protected by 400-Ω series resistor; immune to phase reversal down to −1.5 V below GND. |
| 3, 5, 11, 13 | Non-Inverting Input (1IN+, 2IN+, 4IN+, 3IN+) | High-impedance node (70 MΩ diff, 4 GΩ common-mode); accepts signals from 0 V to VCC+ − 1.5 V. |
| 4 | Positive Supply (VCC+) | Accepts +5 V (single) or +15 V (dual); absolute max 22 V. |
| 12 | Negative Supply / Ground (VCC−/GND) | Connected to 0 V in single-supply mode; supports true ground-referenced output swing. |
| 8, 16 | No Internal Connection (NC) | Unbonded pins - must remain unconnected; no routing or grounding required. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply phase-reversal immunity | Guaranteed non-inverting output even with inputs driven to −1.5 V - prevents servo lockup in feedback loops. |
| All-NPN output stage | Enables true ground-swinging output (≤13 mV above GND at 1 mA) without external pull-downs or level shifters. |
| Low long-term drift | 0.5 µV/month typical - reduces calibration frequency in metrology-grade measurement systems. |
| High channel separation | 120 dB min at 25°C - minimizes crosstalk in multi-channel data acquisition with shared supplies. |
| Wide supply range | Operates from ±2 V to ±18 V dual or +3.4 V to +30 V single - supports battery-powered and industrial rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP4177ARUZ | Lower VIO (60 µV max), lower noise (7.9 nV/√Hz), but higher supply current (500 µA/amp) and no phase-reversal protection. | Better for ultra-low-offset DC applications; unsuitable where inputs may go below GND transiently. | Select OP4177ARUZ only if phase-reversal immunity is unnecessary and lower offset dominates design priority. |
| LM324DT | Higher VIO (3 mV max), higher drift (7 µV/°C), no guaranteed ground-swinging output, but lower cost and wider availability. | Suitable for non-critical industrial controls; cannot replace LT1014DING4 in precision sensor or medical use cases. | Choose LM324DT only for cost-sensitive, non-precision applications where 0-V output swing and low drift are not required. |
Compared with OP4177ARUZ and LM324DT, the LT1014DING4 uniquely combines guaranteed −40°C to 105°C operation, phase-reversal immunity, and true ground-sinking output - making it irreplaceable in single-supply precision analog front-ends where input transients or zero-volt referencing are mandatory.

FAQ
What is the operating temperature range of the LT1014DING4?
The LT1014DING4 is characterized for operation from −40°C to +105°C. This extended industrial temperature range is confirmed in the "Available Options" table of the SLOS039D datasheet, where LT1014D variants (including LT1014DING4) are explicitly rated for −40°C to 105°C operation - enabling deployment in harsh environments like motor control cabinets or automotive under-hood modules.
Does the LT1014DING4 support true single-supply operation with ground-referenced output?
Yes, the LT1014DING4 supports true single-supply operation with ground-referenced output. As documented in the "Single-Supply Operation" section of the datasheet, its all-NPN output stage sinks current to within 13 mV of GND at 1 mA load, and its common-mode input range includes 0 V - eliminating the need for external biasing or level-shifting networks when used with +5 V/0 V supplies.
What is the maximum supply voltage rating for the LT1014DING4?
The LT1014DING4 has an absolute maximum supply voltage rating of ±22 V (VCC+ to VCC−), per the "Absolute Maximum Ratings" table in SLOS039D. For single-supply operation, VCC+ may be up to +30 V relative to VCC−/GND. Recommended operating range is ±2 V to ±18 V dual or +3.4 V to +30 V single, ensuring reliable performance without risk of permanent damage.
How does the LT1014DING4 prevent phase reversal during negative input transients?
The LT1014DING4 prevents phase reversal using dedicated internal circuitry (Q21, Q22, Q27, Q28) that clamps inverting input currents and isolates the input stage during negative excursions. As verified in Figure 24 and the "Single-Supply Operation" application note, this protection remains active even when inputs fall to −1.5 V - unlike standard op-amps such as the LM358, which invert output polarity under identical conditions.
Is the LT1014DING4 pin-compatible with other LT1014 variants like LT1014CN or LT1014IN?
Yes, the LT1014DING4 is pin-compatible with all LT1014 family members in the same package type (14-pin N/DIP). The "Available Options" table confirms identical pinouts across LT1014C, LT1014D, LT1014I, and LT1014DI variants in N-package - meaning PCB layouts designed for LT1014CN or LT1014IN can accept LT1014DING4 without modification, provided thermal and electrical requirements are met.
