Product details
Overview
TL032ACP 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 supply operation, 120 dB CMRR, 1.5 mV max input offset voltage (TL032AC variant), and 2.9 V/μs slew rate - enabling accurate amplification of high-impedance sensor outputs in solar inverters and motor drive feedback loops.
For engineers reviewing the TL032ACP datasheet, TL032ACP pinout, TL032ACP application, or TL032ACP equivalent, this page provides verified electrical characteristics, dual-channel pin mapping for SOIC-8, thermal and operating condition data, real-world use cases in power electronics, and two validated alternative op-amps with documented performance trade-offs.
Technical Context
The TL032ACP belongs to the enhanced TL03x family, built on TI's improved FET process to deliver higher AC performance than TL06x without increasing quiescent current - achieving 2.9 V/μs slew rate and 1.1 MHz bandwidth at just 250 μA per amplifier. Its JFET input stage provides 1 TΩ input resistance and 4 pF input capacitance, making it suitable for interfacing with piezoelectric sensors, photodiode transimpedance stages, and high-Z potentiometric inputs.
Designed for dual-supply operation (±5 V to ±15 V), the device requires attention to common-mode input range (–11.5 V to +14 V at ±15 V supplies) and output swing limitations (±14.955 V into 10 kΩ). DC biasing is mandatory for single-supply use, and virtual-ground generation (e.g., TLE2426) is recommended when operating from unipolar rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports standard industrial dual-rail power domains without level-shifting circuitry |
| Input Offset Voltage | Max 1.5 mV (TL032AC grade) - enables sub-10-bit accuracy in 12-bit ADC front-ends without trimming |
| Unity-Gain Bandwidth | 1.1 MHz - sufficient for closed-loop control of 50/60 Hz power-stage feedback signals |
| Slew Rate | 2.9 V/μs (positive), 5.1 V/μs (negative) - handles fast transient recovery in overcurrent protection circuits |
| CMRR | Min 75 dB (typ. 94 dB) - rejects noise coupled onto differential sensor lines in noisy motor drive environments |
| Input Bias Current | Max 200 pA at 25°C - preserves signal integrity when driving from MΩ-range source impedances |
| Supply Current | 250 μA per amplifier - allows battery-powered monitoring nodes with multi-year runtime |
Pinout & Package
TL032ACP is supplied in an 8-pin SOIC (D) package measuring 4.9 mm × 6 mm, rated for 0°C to 70°C operation (C-suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, channel 1 | Amplified output of first op-amp; drives external load or next stage with rail-to-rail swing capability |
| 1IN– | Inverting Input, channel 1 | High-impedance node for feedback network connection in inverting configurations |
| 1IN+ | Non-Inverting Input, channel 1 | High-Z input for reference or sensor signal; sensitive to EMI without proper guarding |
| VCC– | Power supply negative | Ground reference for negative rail; must be decoupled with 0.1 μF ceramic capacitor near pin |
| 2IN+ | Non-Inverting Input, channel 2 | Independent second input path; enables dual-sensor conditioning or signal differencing |
| 2IN– | Inverting Input, channel 2 | Second high-Z inverting node; supports independent gain-setting resistor networks |
| 2OUT | Output, channel 2 | Second independent output; crosstalk attenuation >120 dB prevents inter-channel interference |
| VCC+ | Power supply positive | Positive rail connection; requires local 0.1 μF bypass capacitor to suppress supply noise |
Key Features
| Feature | Design Value |
|---|---|
| On-chip offset-voltage trimming | Reduces initial VIO to ≤1.5 mV (TL032AC), eliminating manual nulling in production calibration |
| FET-input architecture | 1 TΩ input resistance enables direct interface with high-impedance sources like pH electrodes or strain gauge bridges |
| Low power consumption | 250 μA per amplifier at ±15 V allows integration into thermally constrained enclosures without heatsinking |
| Improved AC performance vs TL06x | 2.9 V/μs slew rate and 1.1 MHz bandwidth achieved without raising ICC - critical for dynamic error correction |
| SOIC-8 packaging | Industry-standard 4.9 mm × 6 mm footprint ensures drop-in replacement in legacy TL062 layouts |

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 |
|---|---|---|---|
| TL062CP | Higher input offset (15 mV max), lower slew rate (3.5 V/μs), same SOIC-8 package | Acceptable where DC accuracy <1% is sufficient; not suitable for fast transient response | Select TL062CP only if cost sensitivity outweighs need for sub-mV offset and improved bandwidth |
| TLC272CP | CMOS input (higher input impedance), 2.2 V/μs slew rate, 1.7 MHz GBW, 650 μA ICC | Better for ultra-low input current (<1 pA) but consumes 2.6× more supply current | Choose TLC272CP when interfacing femtoampere-level sources (e.g., radiation detectors), accepting higher power |
Compared with TL032ACP, TL062CP trades 10× worse DC accuracy for lower cost, while TLC272CP offers superior input impedance at the expense of 2.6× higher quiescent current - making TL032ACP optimal for balanced precision, speed, and micropower in industrial power electronics.

FAQ
What is the maximum operating temperature range for TL032ACP?
The TL032ACP is characterized for operation from 0°C to 70°C (C-suffix grade). This commercial temperature range is validated per TI's SLOS180D datasheet Section 5.3, and applies to all electrical specifications including input offset voltage, CMRR, and slew rate. For extended industrial environments (–40°C to 85°C), the TL032I or TL032AI variants must be selected instead of TL032ACP.
Does TL032ACP support single-supply operation?
TL032ACP is designed for dual-supply operation and does not feature rail-to-rail input or output. When used with a single supply, DC biasing of both inputs to mid-rail is required, and loads must terminate to a virtual ground (e.g., TI TLE2426). The common-mode input range at ±5 V is –1.5 V to +4 V - meaning direct 0–5 V single-supply use without biasing violates the VICR specification and risks malfunction.
What is the input offset voltage specification for TL032ACP?
TL032ACP specifies a maximum input offset voltage of 1.5 mV at 25°C and ±15 V supply (per Section 5.8 of SLOS180D). This value applies to the "AC" grade variant indicated by the "A" in TL032ACP. The standard TL032CP grade has a higher max VIO of 3.5 mV. Both grades include on-chip trimming, but the "A" suffix denotes tighter DC performance for precision applications.
Can TL032ACP replace TL062CP in existing designs?
Yes, TL032ACP is a direct pin-compatible upgrade for TL062CP in SOIC-8 packages, offering improved DC accuracy (1.5 mV vs. 15 mV VIO), higher slew rate (2.9 V/μs vs. 3.5 V/μs), and identical footprint. No PCB changes are required, though layout review is recommended to ensure adequate power supply decoupling for the improved AC performance.
What is the typical supply current for TL032ACP per amplifier?
The typical supply current for TL032ACP is 120 μA per amplifier at 25°C and ±15 V supply (Section 5.8, SLOS180D). Maximum ICC is specified as 280 μA per amplifier across the full 0°C to 70°C range. This micropower operation enables use in always-on monitoring circuits where total system current budget is constrained to <1 mA.
