Product details
Overview
TL032AIDR from Texas Instruments is a dual-channel, JFET-input operational amplifier optimized for low-power, low-offset precision applications. It delivers 1.1 MHz unity-gain bandwidth, ±15 V and ±5 V supply operation, 2.9 V/μs slew rate (positive), and 1.5 mV max input offset voltage at 25°C - enabling high-impedance sensor interfacing in solar inverter feedback loops and motor drive current sensing.
For engineers reviewing the TL032AIDR datasheet, TL032AIDR pinout, TL032AIDR application, or TL032AIDR equivalent, this device is selected for micropower FET-input performance where DC accuracy, input impedance >1 TΩ, and stable AC response under ±5 V to ±15 V dual supplies are required - especially in space-constrained industrial analog signal conditioning.
Technical Context
The TL032AIDR uses TI's enhanced FET process with on-chip offset-voltage trimming, achieving tighter DC specs than the TL06x family without increasing quiescent current. Its dual-amplifier architecture supports independent channel operation with 120 dB crosstalk attenuation, ensuring minimal inter-channel interference in multi-loop control systems.
Designed for dual-supply use, it requires attention to common-mode input range (–11.5 V to +14 V at ±15 V supplies) and output swing limits; single-supply operation demands DC biasing and virtual-ground referencing via external circuitry like the TLE2426.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±5 V to ±15 V - supports standard industrial dual-rail power domains without level-shifting. |
| Input Offset Voltage (max) | 1.5 mV at 25°C - enables accurate amplification of sub-10 mV sensor signals without nulling circuitry. |
| Unity-Gain Bandwidth | 1.1 MHz - sufficient for closed-loop control up to ~100 kHz with phase margin ≥60°. |
| Slew Rate (SR+) | 2.9 V/μs - allows clean reproduction of 100 kHz sine waves at ~1.8 VPP without distortion. |
| Input Bias Current (max) | 200 pA at 25°C - preserves signal integrity when driving from high-impedance sources (>100 MΩ). |
| Common-Mode Rejection Ratio | 94 dB - suppresses noise coupled equally to both inputs in noisy motor-drive environments. |
| Supply Current per Amplifier | 280 μA max at ±15 V - enables battery-powered or energy-harvesting designs with <600 μA total quiescent draw. |
Pinout & Package
TL032AIDR is housed in an 8-pin SOIC (D package), 4.9 mm × 6.0 mm body size, with surface-mount compatibility and thermal resistance θJA = 86 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, channel 1 | Amplified output signal for first op-amp; drives loads ≥10 kΩ to maintain specified swing. |
| 1IN– | Inverting Input, channel 1 | Differential input node; high-impedance FET path enables precision feedback network design. |
| 1IN+ | Non-Inverting Input, channel 1 | High-Z input for reference or sensor signal; common-mode range must stay within spec limits. |
| VCC– | Power supply negative | Negative rail connection; must be decoupled locally with 0.1 μF ceramic capacitor. |
| 2IN+ | Non-Inverting Input, channel 2 | Independent second input; no internal coupling - usable for separate signal paths or dual-loop control. |
| 2IN– | Inverting Input, channel 2 | Second differential input; identical electrical characteristics to channel 1 for matched performance. |
| 2OUT | Output, channel 2 | Second independent output; 120 dB crosstalk attenuation prevents interaction with channel 1. |
| VCC+ | Power supply positive | Positive rail connection; shared supply with both amplifiers; requires local decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip offset-voltage trimming | Reduces max VIO to 1.5 mV (vs. 3.5 mV untrimmed), lowering calibration overhead in production test. |
| FET-input architecture | Input impedance >1012 Ω enables direct interface with piezoelectric sensors, pH electrodes, and photodiode transimpedance stages. |
| Enhanced slew rate vs. TL062 | 2.9 V/μs (TL032A) vs. 3.5 V/μs (TL062) - achieves comparable speed at lower power (280 μA vs. 350 μA). |
| Wide supply range support | Operates from ±5 V to ±15 V - simplifies reuse across legacy and new designs without redesigning bias networks. |
| Industrial temperature grade | Specified from –40°C to +85°C - qualified for motor drives and solar inverters exposed to ambient thermal cycling. |
Applications
| Solar Inverter Current Sensing | AC Motor Drive Feedback |

Use Value: 120 dB crosstalk attenuation ensures phase-current measurements remain independent, critical for vector control fidelity. |
| Single-Phase Online UPS Monitoring | Industrial Sensor Signal Conditioning |

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 |
|---|---|---|---|
| TL032CDR | Wider input offset voltage (3.5 mV max), C-temp grade (0°C to 70°C), same pinout and SOIC-8 package. | Suitable for commercial-grade systems where extended temperature range is not required. | Select TL032CDR only if cost sensitivity outweighs need for –40°C startup capability and tighter offset spec. |
| TL072CDR | Higher slew rate (13 V/μs), higher supply current (2.8 mA), no on-chip offset trim (10 mV max VIO). | Better for wideband AC-coupled audio or fast transient detection; less suitable for precision DC-coupled sensing. | Choose TL072CDR when bandwidth >3 MHz is needed and power budget allows >5× higher ICC; avoid for low-offset DC applications. |
Compared with TL032CDR and TL072CDR, the TL032AIDR provides the optimal balance of low offset (1.5 mV), micropower operation (280 μA), and industrial temperature range - making it uniquely suited for precision, low-power, high-reliability analog signal chains in renewable energy and motion control.

FAQ
What is the maximum operating temperature range for TL032AIDR?
The TL032AIDR is rated for operation from –40°C to +85°C, meeting industrial temperature requirements. This specification is validated per the I-suffix designation in the TL032A product family and confirmed in Section 5.10 of the SLOS180D datasheet, where electrical characteristics are guaranteed across the full range.
Does TL032AIDR support single-supply operation?
TL032AIDR is designed for dual-supply operation and does not feature rail-to-rail input or output. Single-supply use requires external DC biasing of inputs and a virtual-ground reference (e.g., TI TLE2426) at mid-supply to maintain proper common-mode and output swing - as explicitly stated in the "Description" section of the datasheet.
How does TL032AIDR differ from TL032IDR?
TL032AIDR features on-chip offset-voltage trimming, resulting in tighter input offset voltage (1.5 mV max vs. 3.5 mV for TL032IDR) and lower temperature coefficient (10.8 μV/°C vs. 11.5 μV/°C). Both share identical pinout, package, and temperature range, but TL032AIDR delivers superior DC precision for measurement-critical roles.
What is the typical input capacitance of TL032AIDR?
The TL032AIDR has a typical input capacitance of 4 pF per input terminal, as specified in Table 5.4–5.15 of the SLOS180D datasheet. This low value minimizes phase shift in high-frequency feedback networks and supports stable operation with capacitive sources up to ~100 pF.
Can TL032AIDR replace TL062 in existing designs?
Yes - TL032AIDR is a direct upgrade for TL062, offering higher slew rate (2.9 V/μs vs. 3.5 V/μs), lower input offset (1.5 mV vs. 15 mV), and identical SOIC-8 pinout. No PCB changes are required, though layout review is recommended to verify decoupling and grounding for improved noise immunity.
