Product details
Overview
TL032ID from Texas Instruments is a dual-channel, JFET-input operational amplifier optimized for low-power, low-offset precision applications in industrial and energy systems. It delivers 1.1 MHz unity-gain bandwidth, ±15 V max supply voltage, 2.9 V/μs typical slew rate, 1.5 mV max input offset voltage (at 25°C), and operates across –40°C to 85°C. It interfaces with high-impedance sensors in solar inverter feedback loops and motor drive current sensing.
For engineers reviewing the TL032ID datasheet, TL032ID pinout, TL032ID application, or TL032ID equivalent, this page provides verified specifications, SOIC-8 package layout, real-world use cases in power conversion and control, and validated alternative parts for design flexibility and supply continuity.
Technical Context
The TL032ID uses Texas Instruments' enhanced LinCMOS™ FET process to achieve higher AC performance than TL06x while maintaining micropower operation (120–280 μA per amplifier). Its dual-channel architecture supports independent signal conditioning paths without crosstalk degradation - VO1/VO2 attenuation exceeds 120 dB.
Designed for dual-supply operation, it requires careful attention to common-mode input range (–11.5 V to +14 V at ±15 V supplies) and output swing limits. Single-supply use demands DC biasing and virtual-ground referencing via external circuitry like the TLE2426.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports standard industrial dual-rail supplies; not rated for single-supply operation without biasing. |
| Input Offset Voltage | Max 1.5 mV at 25°C (TL032AI grade) - enables accurate DC-coupled amplification in precision sensor front-ends. |
| Unity-Gain Bandwidth | 1.1 MHz - sufficient for anti-aliasing, current loop control, and medium-speed signal conditioning up to ~100 kHz closed-loop. |
| Slew Rate | 2.9 V/μs (typical, positive); 5.1 V/μs (typical, negative) - supports fast transient response in motor phase-current monitoring. |
| Input Bias Current | ≤200 pA at 25°C - preserves signal integrity when interfacing with >1 MΩ source impedances (e.g., piezoelectric or photodiode sensors). |
| Common-Mode Rejection | Min 75 dB (±15 V) - rejects noise on shared reference rails in noisy inverter gate-drive circuits. |
| Crosstalk Attenuation | ≥120 dB - ensures channel isolation in dual-path feedback (e.g., voltage + current sensing in UPS inverters). |
Pinout & Package
TL032ID is supplied in an 8-pin SOIC (D) package measuring 4.9 mm × 6.0 mm, with standard JEDEC MS-012AC footprint and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, channel 1 | Amplified output of first op-amp; drives feedback networks or ADC inputs directly. |
| 1IN– | Inverting Input, channel 1 | High-impedance node for precision differential or inverting gain configurations. |
| 1IN+ | Non-Inverting Input, channel 1 | Accepts high-Z sensor signals; common-mode range must stay within spec limits. |
| VCC– | Power supply negative | Ground reference for dual-supply operation; must be connected to system negative rail. |
| 2IN+ | Non-Inverting Input, channel 2 | Independent second input path; no internal coupling to channel 1. |
| 2IN– | Inverting Input, channel 2 | Supports separate gain stage or comparator-like configuration with hysteresis. |
| 2OUT | Output, channel 2 | Second independent output; usable for auxiliary functions (e.g., overcurrent flag generation). |
| VCC+ | Power supply positive | Positive supply rail connection; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip offset-voltage trimming | Reduces initial VIO to ≤1.5 mV (TL032AI), minimizing calibration effort in production test. |
| FET-input architecture | Input resistance ≥1 TΩ and bias current ≤200 pA enable direct interface with high-impedance sources without loading error. |
| Enhanced slew rate vs. TL062 | 2.9 V/μs (vs. ~0.4 V/μs for TL062) allows stable closed-loop response in 50–100 kHz control loops. |
| Low quiescent current | 120–280 μA per amplifier enables battery-backed or energy-harvesting subsystems with extended runtime. |
| Extended temperature range | Rated for –40°C to +85°C operation - suitable for under-hood automotive modules and outdoor solar inverters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Higher slew rate (13 V/μs), wider bandwidth (3 MHz), but higher ICC (1.4 mA) and no factory offset trim. | Better for wideband audio or fast control loops; unsuitable for ultra-low-power designs. | Select when speed outweighs power budget; verify thermal margin due to higher dissipation. |
| OPA2340UA | Rail-to-rail output, lower VIO (0.25 mV typ), but limited supply range (±2.75 V max) and higher cost. | Preferred for low-voltage battery-powered systems; incompatible with ±15 V industrial rails. | Choose only if RRO and sub-mV offset are mandatory and supply voltage ≤±2.75 V. |
Compared with TL032ID, TL072CDR trades micropower operation for speed and bandwidth, while OPA2340UA sacrifices supply voltage headroom and cost efficiency to achieve rail-to-rail output and superior DC accuracy - neither is pin-compatible, requiring PCB redesign.

FAQ
What is the maximum supply voltage rating for TL032ID?
The TL032ID is rated for absolute maximum supply voltages of ±18 V, but its recommended operating range is ±5 V to ±15 V. Operation at ±18 V is not guaranteed for parametric performance or reliability; sustained use beyond ±15 V may degrade long-term stability or cause thermal stress. Always observe derating guidelines in TI's SLOS180D datasheet section 5.1.
Does TL032ID support single-supply operation?
TL032ID is designed for dual-supply operation and does not feature rail-to-rail input or output. To operate from a single supply, the input common-mode range and output swing must be constrained using external biasing - e.g., a mid-supply virtual ground generated by TI's TLE2426. Without such circuitry, valid operation cannot be assured, especially near supply rails.
What is the input offset voltage specification for TL032ID at full temperature range?
For TL032ID (I-suffix, –40°C to +85°C), the input offset voltage is specified at ≤5.3 mV maximum across the full temperature range. At 25°C, it is ≤1.5 mV (TL032AI grade). The temperature coefficient is 11.4 μV/°C, meaning offset drift contributes <1.0 mV over an 85°C span - critical for uncalibrated industrial sensor interfaces.
How does TL032ID compare to TL062 in terms of power and performance?
TL032ID consumes comparable quiescent current (120–280 μA) to TL062 but delivers significantly better AC performance: 1.1 MHz bandwidth vs. 0.35 MHz, and 2.9 V/μs slew rate vs. 0.4 V/μs. It also features on-chip offset trimming, reducing initial VIO by ~50% versus TL062. These improvements make TL032ID a direct functional upgrade without increasing power budget.
Is TL032ID pin-compatible with other dual op-amps in SOIC-8 packages?
TL032ID follows the industry-standard dual-op-amp SOIC-8 pinout (1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, VCC+), matching TL062, TL072, and LM358. However, electrical differences - including input stage topology (JFET vs. bipolar), supply range, and output swing - require verification of signal chain compatibility before drop-in replacement.
