Product details
Overview
TL032CPSR 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, 1012 Ω input resistance, and 2.9 V/μs slew rate - enabling accurate amplification of high-impedance sensor outputs in solar inverter feedback loops.
For engineers reviewing the TL032CPSR datasheet, TL032CPSR pinout, TL032CPSR application, or TL032CPSR equivalent, this page provides verified specifications, SOIC-8 package layout, real-world use cases in motor drive current sensing and UPS voltage regulation, and validated alternative options with documented performance trade-offs.
Technical Context
The TL032CPSR uses Texas Instruments' enhanced LinCMOS FET process to achieve micropower operation (120–250 μA per amplifier) without sacrificing AC performance - delivering higher slew rate and bandwidth than TL06x predecessors while maintaining identical supply current. Its FET input stage enables direct interfacing with high-impedance sources such as photodiode arrays or piezoelectric sensors.
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 power domains without level-shifting |
| Input Offset Voltage | 0.69 mV (max, 25°C) - enables sub-mV DC accuracy in precision transducer interfaces |
| Unity-Gain Bandwidth | 1.1 MHz - sufficient for closed-loop control up to ~100 kHz with phase margin ≥60° |
| Slew Rate | 2.9 V/μs (positive), 5.1 V/μs (negative) - handles fast transient signals in motor current sensing |
| CMRR | 94 dB (typ, ±15 V) - rejects common-mode noise in noisy industrial environments |
| Input Resistance | 1012 Ω - preserves signal integrity when buffering megohm-level sensor impedances |
| Supply Current | 120–250 μA per amplifier - enables multi-channel designs with <1 mA total quiescent draw |
Pinout & Package
TL032CPSR is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.9 mm × 6.0 mm, compliant with JEDEC MS-012, and rated for 0°C to 70°C operation (C-suffix).

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL062CDR | Higher input offset (15 mV max), lower slew rate (3.5 V/s), no on-chip trimming | Acceptable where cost sensitivity outweighs precision requirements | Use only if system-level calibration compensates for higher VIO and slower response |
| OPA2340UA | Rail-to-rail output, 1.25 MHz GBW, 200 μA per amp, CMOS input (lower IB) | Better suited for single-supply, low-voltage (<5 V) systems requiring full output swing | Select when operating from 3.3 V or 5 V single rails with load termination to mid-rail |
Compared with TL062CDR, TL032CPSR offers 20× lower input offset and 800× faster slew rate at identical supply current; versus OPA2340UA, TL032CPSR provides superior common-mode rejection (94 dB vs. 80 dB) and higher supply voltage tolerance (±15 V vs. ±8 V), making it more robust in industrial dual-rail environments.

FAQ
What is the maximum operating temperature range for TL032CPSR?
The TL032CPSR is characterized for operation from 0°C to 70°C, as indicated by its "C" temperature suffix. This makes it suitable for commercial and industrial indoor applications but not extended-temperature environments such as under-hood automotive or outdoor power electronics enclosures where −40°C to 85°C rating (I-suffix) would be required. Always verify thermal derating margins in high-power PCB layouts.
Can TL032CPSR operate from a single 5-V supply?
TL032CPSR is designed for dual-supply operation and does not support true single-supply functionality. When used with a 5-V rail, a virtual ground (e.g., TI TLE2426) must be generated at 2.5 V to bias inputs and loads appropriately. Without proper DC biasing, the device will clip or saturate due to violation of common-mode input range (−1.5 V to +4 V referenced to VCC−) and output swing limits.
What is the input bias current specification for TL032CPSR?
TL032CPSR exhibits an input bias current of 10–200 pA at 25°C, rising to 50–400 pA at 70°C. This ultra-low value stems from its FET input stage and enables minimal voltage error across high-value feedback resistors (e.g., 1 MΩ), critical for precision integrators and high-gain transimpedance amplifiers. Always guard input traces and use low-leakage PCB materials in sensitive designs.
How does TL032CPSR compare to TL032CP in terms of package and compatibility?
TL032CPSR and TL032CP share identical electrical specifications and pinout but differ in packaging: TL032CPSR uses SOIC-8 (4.9 mm × 6.0 mm), while TL032CP uses PDIP-8 (9.81 mm × 9.43 mm). They are functionally interchangeable in schematic design, but PCB layout must match the respective footprint - SOIC requires reflow-compatible pads and stencil-defined solder paste, whereas PDIP is through-hole compatible.
Is TL032CPSR RoHS-compliant and lead-free?
Yes, TL032CPSR is RoHS-compliant and lead-free, meeting J-STD-609 Category 1 marking requirements. The SOIC-8 package uses matte tin (Sn) lead finish and conforms to IPC/JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3), requiring bake or dry-pack handling prior to reflow if exposed beyond floor life. Full compliance documentation is available in TI's official product change notices.
