Product details
Overview
TL032CD from Texas Instruments is a dual FET-input operational amplifier optimized for low-power, low-offset precision analog signal conditioning in industrial and energy systems. It delivers 1.1 MHz unity-gain bandwidth, ±15 V or ±5 V dual-supply operation, 120 dB CMRR, 1.5 mV max input offset voltage (C-suffix, 25°C), and 2.9 V/μs typical slew rate - enabling accurate amplification of high-impedance sensor outputs in solar inverters and motor drive feedback loops.
For engineers reviewing the TL032CD datasheet, TL032CD pinout, TL032CD application, or TL032CD equivalent, this page provides verified specifications, SOIC-8 package details, real-world use cases in AC drive control and string inverter monitoring, and validated alternative options for design continuity and sourcing resilience.
Technical Context
The TL032CD uses Texas Instruments' enhanced LinCMOS™ FET process to achieve higher input impedance (>1012 Ω) and improved AC performance over legacy TL06x amplifiers without increasing supply current - maintaining only 120–250 μA per amplifier at ±5 V or ±15 V. Its rail-to-rail compatible output swing (±14.955 V at ±15 V, RL = 10 kΩ) and 120 dB crosstalk attenuation support multi-channel isolation in compact dual-amplifier configurations.
Designed explicitly for dual-supply operation, the TL032CD requires attention to common-mode input limits (e.g., −11.5 V to +14 V at ±15 V) and output swing constraints when adapted to single-supply topologies; biasing via virtual-ground generators like the TLE2426 is recommended for such implementations.
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 external biasing. |
| Input Offset Voltage | ≤1.5 mV (max, 25°C, C-suffix) - enables DC-coupled precision gain stages with sub-mV error in temperature-stable environments. |
| Unity-Gain Bandwidth | 1.1 MHz - sufficient for anti-aliasing, current sensing, and loop compensation up to ~100 kHz closed-loop bandwidth. |
| Slew Rate | 2.9 V/μs (typical, positive); 5.1 V/μs (typical, negative) - supports fast transient response in motor phase-current feedback paths. |
| Common-Mode Rejection | 75–94 dB - rejects noise coupled across differential sensor inputs in noisy power-stage environments. |
| Input Bias Current | ≤200 pA (max, 25°C) - preserves signal integrity when interfacing with >1 MΩ source impedances (e.g., piezoelectric sensors, pH electrodes). |
| Operating Temperature | 0°C to +70°C - qualified for commercial-grade embedded control modules, not extended industrial or automotive ranges. |
Pinout & Package
TL032CD is supplied in an 8-pin SOIC (D) package measuring 4.9 mm × 6.0 mm, compliant with JEDEC MS-012, with standard surface-mount footprint and thermal resistance θJA = 86°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, channel 1 | Amplified output of first op-amp; drives external load or next stage with ±14.955 V swing at ±15 V supply. |
| 1IN− | Inverting Input, channel 1 | High-impedance (≥1012 Ω) node for feedback or signal inversion; sensitive to PCB leakage and EMI. |
| 1IN+ | Non-Inverting Input, channel 1 | High-impedance node for reference or sensor input; requires matched trace routing to minimize offset drift. |
| VCC− | Power supply negative | Negative rail connection; must be decoupled locally with 0.1 μF ceramic capacitor near pin. |
| 2IN+ | Non-Inverting Input, channel 2 | Independent second high-Z input; enables dual-path signal conditioning (e.g., current + voltage sensing) on one IC. |
| 2IN− | Inverting Input, channel 2 | Second independent inverting input; supports separate feedback networks per channel without interaction. |
| 2OUT | Output, channel 2 | Second independent output; crosstalk attenuation ≥120 dB ensures minimal inter-channel coupling. |
| VCC+ | Power supply positive | Positive rail connection; shared supply for both amplifiers; requires local 0.1 μF ceramic decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| FET input architecture | Input resistance ≥1012 Ω enables direct interface with high-impedance transducers without loading error. |
| On-chip offset trimming | Reduces initial VIO to ≤1.5 mV (TL032C), improving DC accuracy in open-loop sensor interfaces. |
| Low quiescent current | 120–250 μA per amplifier allows battery-backed or energy-harvesting applications with tight power budgets. |
| Enhanced slew rate vs. TL062 | 2.9 V/μs (vs. 3.5 V/μs for TL062) with identical supply current - improves transient fidelity without power penalty. |
| Dual-channel integration | Two fully independent amplifiers in SOIC-8 reduce board area and component count versus discrete solutions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual FET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL062CD | Higher input offset (6 mV max), lower slew rate (3.5 V/μs), same SOIC-8 package and pinout. | Acceptable where DC accuracy <5 mV and bandwidth <0.6 MHz suffice; less suitable for fast current sensing. | Lower-cost drop-in replacement if system-level calibration compensates for higher VIO and slower dynamics. |
| TLV2462IDR | Rail-to-rail I/O, 6.4 V/μs slew rate, 2.2 MHz GBW, 600 μA supply current - significantly faster but higher power. | Better for single-supply designs and wider dynamic range; unsuitable where ultra-low quiescent current (<250 μA) is mandatory. | Select when higher speed and rail-to-rail operation justify 2.4× higher supply current and different input/output voltage ranges. |
Compared with TL032CD, TL062CD trades precision and speed for cost and legacy compatibility, while TLV2462IDR offers modern rail-to-rail performance at higher power - making TL032CD optimal for dual-supply, low-power, medium-bandwidth industrial analog signal chains.

FAQ
What is the maximum supply voltage rating for TL032CD?
The TL032CD has an absolute maximum supply voltage rating of ±18 V, but it is fully specified and characterized for reliable operation from ±5 V to ±15 V. Operation beyond ±15 V may exceed guaranteed performance limits and is not recommended for production designs without thorough validation of parameters like input offset drift and output swing.
Does TL032CD support single-supply operation?
The TL032CD is designed for dual-supply operation and is not characterized for true single-supply use. To operate from a single rail, external DC biasing (e.g., using TI's TLE2426 virtual-ground generator) is required to establish mid-supply common-mode references for inputs and outputs - otherwise, input range violations and output clipping will occur.
What is the input offset voltage specification for TL032CD at 70°C?
For TL032CD (C-suffix), the input offset voltage is specified at ≤4.5 mV maximum across the full 0°C to +70°C operating range. At 25°C, it is tighter - ≤1.5 mV max - and the temperature coefficient is 11.5 μV/°C, contributing to predictable drift behavior in thermally managed enclosures.
How does TL032CD compare to TL032ID in terms of temperature range?
The TL032CD is rated for 0°C to +70°C operation, while the TL032ID extends to −40°C to +85°C. Both share identical electrical characteristics at 25°C, but TL032ID guarantees performance across the wider industrial temperature range - including higher input bias current (up to 0.9 nA at 85°C) and slightly relaxed offset drift specs.
Is TL032CD pin-compatible with TL062CD?
Yes, TL032CD and TL062CD share identical SOIC-8 pinouts and package dimensions (4.9 mm × 6.0 mm), allowing direct PCB replacement. However, TL032CD offers improved input offset (1.5 mV vs. 6 mV), higher slew rate (2.9 V/μs vs. 3.5 V/μs), and better CMRR - delivering measurable performance gains without layout changes.
