Product details
Overview
TL032CP from Texas Instruments is a dual-channel, JFET-input operational amplifier optimized for low-power, low-offset precision signal conditioning 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 (positive), 10¹² Ω input resistance, and 0.69 mV max input offset voltage at 25°C - enabling high-impedance sensor interfacing in solar inverters and motor drive feedback loops.
For engineers reviewing the TL032CP datasheet, TL032CP pinout, TL032CP application, or TL032CP equivalent, this page provides verified electrical characteristics, dual-amplifier channel isolation data (120 dB crosstalk attenuation), thermal performance (θJA = 86°C/W), and validated alternatives for micropower FET op-amp replacement in ±5 V to ±15 V dual-supply designs.
Technical Context
The TL032CP uses Texas Instruments' enhanced LinCMOS™ FET process to achieve improved DC accuracy (on-chip offset trimming) and AC performance (higher slew rate and bandwidth) over legacy TL062 without increasing quiescent current. Its dual-channel architecture supports independent signal paths with guaranteed 120 dB channel-to-channel crosstalk attenuation.
Designed for dual-supply operation, the TL032CP requires attention to common-mode input voltage limits (e.g., −11.5 V to +14 V at ±15 V supplies) and output swing constraints (±12.5 V min at ±15 V, RL = 10 kΩ). It is not characterized for single-supply use; TI recommends TLC-series amplifiers for such applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports standard industrial dual-rail power domains without derating. |
| Input Offset Voltage | 0.69 mV max (25°C, TL032C) - enables precise DC-coupled amplification in current-sense and reference-buffer circuits. |
| Unity-Gain Bandwidth | 1.1 MHz - sufficient for anti-aliasing, active filtering, and moderate-speed control loop compensation. |
| Slew Rate | 2.9 V/μs (positive, typ.) - allows clean amplification of signals up to ~100 kHz at 10 VPP without slew-induced distortion. |
| Input Resistance | 10¹² Ω - preserves signal integrity when driving from high-impedance sources like piezoelectric sensors or photodiode transimpedance nodes. |
| Crosstalk Attenuation | 120 dB - ensures minimal interference between channels in dual-path monitoring (e.g., phase A/B current sensing). |
| Quiescent Current | 120 μA per amplifier (typ.) - enables battery-backed or energy-harvesting subsystems with multi-day runtime. |
Pinout & Package
TL032CP is supplied in an 8-pin PDIP (Plastic Dual In-line Package) measuring 9.81 mm × 9.43 mm, rated for 0°C to 70°C operation (C-suffix).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of amplifier channel 1 - drives external load or next-stage input with rail-to-rail compatible swing (±12.5 V min at ±15 V). |
| 2 | 1IN– | Inverting input of channel 1 - used for negative feedback configuration, gain-setting networks, or differential input stages. |
| 3 | 1IN+ | Non-inverting input of channel 1 - accepts high-impedance sensor signals or reference voltages with minimal loading. |
| 4 | VCC– | Negative supply rail connection - must be decoupled locally to minimize noise coupling into both amplifier channels. |
| 5 | 2IN+ | Non-inverting input of channel 2 - electrically isolated from channel 1; supports independent signal conditioning paths. |
| 6 | 2IN– | Inverting input of channel 2 - configured separately for distinct gain or filtering functions without interaction. |
| 7 | 2OUT | Output of amplifier channel 2 - maintains 120 dB channel separation; suitable for parallel processing or redundancy. |
| 8 | VCC+ | Positive supply rail connection - shared by both amplifiers; requires low-ESR bypass capacitor near package pins. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip offset-voltage trimming | Reduces initial VIO to ≤0.69 mV (TL032C), lowering calibration burden in precision analog front-ends. |
| FET input stage | Delivers 10¹² Ω input resistance and sub-100 pA bias current - critical for guarding high-Z pH electrodes or thermopile interfaces. |
| Enhanced slew rate vs. TL062 | 2.9 V/μs (vs. ~1.5 V/μs for TL062) enables faster transient response in motor current-loop comparators or peak detectors. |
| Dual-channel isolation | 120 dB crosstalk attenuation prevents signal bleed between phase-current and DC-link voltage monitoring paths. |
| Low-power micropower operation | 120 μA per amplifier allows integration into always-on subsystems without compromising thermal budget or battery life. |
Applications
| Solar Inverter String Monitoring | AC Motor Drive Current Sensing |
|---|---|

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 |
|---|---|---|---|
| TL072CP | Higher slew rate (13 V/μs), lower input offset (3 mV max), but higher supply current (1.4 mA per amp). | Better for wideband audio or fast control loops; less suitable for battery-powered or thermally constrained designs. | Choose TL072CP when bandwidth/speed outweighs power budget; avoid where <250 μA per amp is required. |
| TL062CP | Lower slew rate (1.5 V/μs), higher input offset (15 mV max), same 8-pin PDIP package and pinout. | Acceptable for slower DC-coupled applications (e.g., basic voltage references); lacks TL032CP's offset trimming. | TL062CP serves as a cost-sensitive drop-in for non-critical analog stages where 0.69 mV VIO is unnecessary. |
Compared with TL072CP and TL062CP, the TL032CP uniquely balances micropower operation (120 μA), trimmed offset (0.69 mV), and usable bandwidth (1.1 MHz), making it optimal for energy-efficient industrial sensing where precision and power coexist.

FAQ
What is the maximum operating temperature range for the TL032CP?
The TL032CP is characterized for operation from 0°C to 70°C, as indicated by its "C" suffix. This commercial-grade temperature range suits indoor industrial equipment, UPS systems, and solar inverter control boards not exposed to extreme ambient conditions. For extended-range applications (−40°C to 85°C), the TL032IP variant is specified and documented in the same datasheet.
Does the TL032CP support single-supply operation?
No, the TL032CP is designed and fully specified for dual-supply operation only (±5 V to ±15 V). Its common-mode input range and output swing are defined relative to symmetric rails. Attempting single-supply use risks violating input voltage limits and degrading performance. For single-supply designs, Texas Instruments recommends the TLC27L2 or TLC2272 families instead.
What is the purpose of the unused pins on the TL032CP PDIP package?
The TL032CP in PDIP has no unused pins - all eight pins are assigned: pins 1/7 are outputs, 2/3/5/6 are inputs, and 4/8 are power rails. Unlike some variants (e.g., TL031ID with offset-null pins), the TL032CP does not include dedicated offset-trim connections; trimming is internal and factory-set, eliminating external component requirements.
How does the TL032CP compare to the TL032AC in terms of offset voltage?
The TL032CP (C-suffix) has a maximum input offset voltage of 0.69 mV at 25°C, while the TL032AC (A-grade C-suffix) improves this to 0.53 mV max under identical conditions. Both share the same temperature range (0°C to 70°C), but the "A" grade offers tighter initial DC accuracy for applications requiring higher baseline precision without calibration.
Can the TL032CP drive a 10 kΩ load across its full output swing?
Yes - the TL032CP guarantees a minimum output swing of ±12.5 V at ±15 V supplies into a 10 kΩ load, per datasheet Section 5.8. This meets the requirement for driving standard industrial ADC inputs or comparator thresholds. Performance degrades with lower loads (<2 kΩ); consult the "Output Voltage Swing vs. Load Resistance" curves in the datasheet for design margining.
