Product details
Overview
TL032CDE4 from Texas Instruments is a dual-channel, JFET-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 μA typical supply current per amplifier, 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 TL032CDE4 datasheet, TL032CDE4 pinout, TL032CDE4 application, or TL032CDE4 equivalent, key selection criteria include its FET-input architecture (10¹² Ω input resistance), crosstalk attenuation of 120 dB between channels, guaranteed operation from 0°C to 70°C, and SOIC-8 package compatibility with legacy TL062 layouts.
Technical Context
The TL032CDE4 implements an enhanced LinCMOS™ FET-input process that improves AC performance over the TL062 while maintaining micropower consumption - achieving 2.9 V/μs slew rate and 1.1 MHz bandwidth without increasing ICC beyond 250 μA per channel. Its dual-amplifier topology supports independent signal paths with 120 dB inter-channel crosstalk suppression.
Designed for dual-supply operation, the device requires adherence to common-mode input limits (e.g., −11.5 V to +14 V at ±15 V supplies) and output swing constraints (±12.5 V min into 10 kΩ). DC biasing is mandatory for single-supply use, and virtual-ground generation (e.g., via 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 external regulation |
| Input Offset Voltage | 0.69 mV max (25°C) - enables accurate DC-coupled amplification of mV-level sensor outputs |
| Unity-Gain Bandwidth | 1.1 MHz - sufficient for anti-aliasing, current sensing, and control-loop compensation up to ~100 kHz |
| Slew Rate | 2.9 V/μs (positive), 5.1 V/μs (negative) - handles fast transient signals in motor phase-current monitoring |
| Input Resistance | 10¹² Ω - preserves signal integrity when buffering high-impedance piezoelectric or photodiode sensors |
| Crosstalk Attenuation | 120 dB - ensures channel isolation in dual-path feedback or differential measurement circuits |
| Supply Current | 120–250 μA per amplifier - enables battery-backed or energy-harvesting designs with multi-day runtime |
Pinout & Package
TL032CDE4 is housed in an 8-pin SOIC (D) package measuring 4.9 mm × 6.0 mm, with standard JEDEC MS-012AC footprint and 1.27 mm pitch - compatible with automated SMT assembly and legacy TL062 PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, channel 1 | Amplified output signal for first op-amp; drives loads ≥10 kΩ for full swing compliance |
| 1IN− | Inverting Input, channel 1 | High-impedance node for feedback network connection or inverting gain configuration |
| 1IN+ | Non-Inverting Input, channel 1 | High-Z input for reference, sensor, or buffered signal routing |
| VCC− | Power supply negative | Connect to system ground or negative rail; decoupling capacitor required near pin |
| 2IN+ | Non-Inverting Input, channel 2 | Independent high-Z input for second signal path; no internal coupling to channel 1 |
| 2IN− | Inverting Input, channel 2 | Separate feedback node for second amplifier; supports independent gain/compensation |
| 2OUT | Output, channel 2 | Second independent output; 120 dB isolation from 1OUT prevents cross-modulation |
| VCC+ | Power supply positive | Connect to positive rail; pair with 0.1 μF ceramic decoupling capacitor at package edge |

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 |
|---|---|---|---|
| TL062CDR | Higher input offset (15 mV max), lower slew rate (1.5 V/μs), same SOIC-8 package | Acceptable where DC accuracy and speed are less critical; higher power consumption (250 μA vs. 120 μA) | Select TL062CDR only for cost-sensitive legacy replacements where 0.69 mV VIO and 2.9 V/μs are not required. |
| TL072CDR | Lower input bias current (30 pA vs. 200 pA), higher slew rate (13 V/μs), same pinout and supply range | Better for wideband audio or fast transient capture; higher noise (18 nV/√Hz vs. 30 nV/√Hz at 1 kHz) | Choose TL072CDR when bandwidth >3 MHz or lower noise is needed; avoid if ultra-low power (<250 μA) is mandatory. |
Compared with TL062CDR, TL032CDE4 offers 22× lower input offset and 93% lower quiescent current; versus TL072CDR, it trades 4.5× higher slew rate for 2.3× lower supply current and superior long-term DC stability - making it optimal for precision, low-power industrial sensing.

FAQ
What is the maximum operating temperature range for TL032CDE4?
The TL032CDE4 is characterized for operation from 0°C to 70°C (C-suffix grade). It meets all electrical specifications across this full industrial temperature range, including input offset voltage, common-mode rejection ratio, and supply current - making it suitable for enclosed power electronics environments without active thermal management.
Does TL032CDE4 support single-supply operation?
TL032CDE4 is designed for dual-supply operation but can be used with single supplies when proper DC biasing is applied. The input common-mode range extends to within 1.5 V of the negative rail and 2 V below the positive rail; for +10 V single supply, inputs must stay between 1.5 V and 8 V, and outputs swing between ~2 V and ~8 V - requiring a mid-rail virtual ground (e.g., TI TLE2426) for AC-coupled signals.
How does TL032CDE4 compare to TL072CDR in terms of noise performance?
TL032CDE4 specifies 30 nV/√Hz input voltage noise at 1 kHz, while TL072CDR specifies 18 nV/√Hz. The TL032CDE4's higher noise is a trade-off for its 120 μA supply current (vs. 2.5 mA for TL072CDR); its 10¹² Ω input resistance and <2 fA/√Hz input current noise make it superior for high-impedance sensor interfaces where voltage noise dominates.
Is TL032CDE4 pin-compatible with TL062CDR?
Yes, TL032CDE4 uses the same SOIC-8 (D) package and identical pinout as TL062CDR - pins 1–4 and 5–8 map directly to 1OUT, 1IN−, 1IN+, VCC− and 2IN+, 2IN−, 2OUT, VCC+. This allows direct replacement on existing PCBs to improve offset, slew rate, and power efficiency without layout changes.
What is the typical supply current per amplifier in TL032CDE4 at ±15 V?
The typical supply current per amplifier in TL032CDE4 is 120 μA at ±15 V and 25°C, with a maximum of 280 μA across the full 0°C to 70°C temperature range. This ultra-low quiescent current enables multi-channel analog front-ends in power-constrained applications such as battery-backed monitoring systems or energy-harvesting nodes using TL032CDE4.
