Product details
Overview
TL032AID from Texas Instruments is a dual-channel, JFET-input operational amplifier optimized for low-power, low-offset precision applications 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), 1.5 mV max input offset voltage (25°C, ±15 V), and 120 dB crosstalk attenuation - enabling high-accuracy signal conditioning in solar inverters and motor drive feedback loops.
For engineers reviewing the TL032AID datasheet, TL032AID pinout, TL032AID application, or TL032AID equivalent, this page provides verified electrical specifications, SOIC-8 package layout, real-world use cases in AC servo control and string inverter sensing, and two validated alternative op-amps with documented parameter trade-offs.
Technical Context
The TL032AID uses Texas Instruments' enhanced LinCMOS™ FET process to achieve higher slew rate and bandwidth than TL06x predecessors without increasing quiescent current - maintaining 120–280 μA per amplifier at ±5 V to ±15 V. Its JFET input stage provides 1 TΩ input resistance and 4 pF input capacitance, supporting high-impedance sensor interfacing.
Designed for dual-supply operation, it specifies common-mode input range from −11.5 V to +14 V (±15 V supplies) and output swing to within 50 mV of rails under 10 kΩ load. Offset voltage is trimmed on-chip, yielding tighter DC performance than standard TL032 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports legacy industrial rail standards and enables direct replacement of TL062 in existing ±12 V or ±15 V designs. |
| Input Offset Voltage | Max 1.5 mV at 25°C, ±15 V - enables sub-10-bit accuracy in 12-bit ADC front-ends without external trimming. |
| Unity-Gain Bandwidth | 1.1 MHz - sufficient for anti-aliasing filtering up to ~100 kHz and closed-loop control loop compensation in servo drives. |
| Slew Rate | 2.9 V/μs (positive), 5.1 V/μs (negative) - allows clean amplification of 100 kHz sine waves at 2 VPP without distortion. |
| Input Bias Current | Max 200 pA at 25°C - preserves signal integrity when buffering piezoelectric sensors or high-value RC networks. |
| Crosstalk Attenuation | 120 dB - ensures channel isolation in dual-sensor monitoring (e.g., phase A/B current sensing) without cross-coupling errors. |
| Operating Temperature | −40°C to +85°C - qualified for industrial motor drives and outdoor solar inverter environments. |
Pinout & Package
TL032AID is supplied in an 8-pin SOIC (D) package measuring 4.9 mm × 6.0 mm, with standard JEDEC MS-012AC footprint and gull-wing leads. Thermal resistance θJA = 86°C/W enables operation up to 85°C ambient without forced cooling in typical PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, channel 1 | Amplified output of first op-amp; capable of sourcing/sinking ±40 mA into 10 kΩ load. |
| 1IN− | Inverting Input, channel 1 | Differential input node; high-impedance (1 TΩ) JFET gate requiring guarded routing in sensitive analog sections. |
| 1IN+ | Non-Inverting Input, channel 1 | Reference input for follower or non-inverting gain configurations; matched bias current minimizes offset error. |
| VCC− | Power supply negative | Negative rail connection; must be decoupled with ≥0.1 μF ceramic capacitor near pin. |
| 2IN+ | Non-Inverting Input, channel 2 | Independent second amplifier input; electrically isolated from channel 1 except via shared supply rails. |
| 2IN− | Inverting Input, channel 2 | Second differential pair input; identical DC and AC specs to channel 1 per datasheet Table 5.10. |
| 2OUT | Output, channel 2 | Second independent output; 120 dB crosstalk ensures <1 μV coupling from 1OUT under full-scale swing. |
| VCC+ | Power supply positive | Positive rail connection; requires local 0.1 μF bypass capacitor to suppress supply noise propagation. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip offset trimming | Reduces max input offset to 1.5 mV (vs. 3.5 mV untrimmed TL032C), cutting initial error by >50% in precision transducer interfaces. |
| FET input architecture | 1 TΩ input resistance and 2 fA/√Hz noise current enable stable biasing of photodiode or strain gauge bridges without leakage-induced drift. |
| Low quiescent current | 120–280 μA per amplifier across ±5 V to ±15 V - supports battery-backed monitoring circuits with multi-year runtime. |
| Enhanced AC performance | 1.1 MHz GBW and 5.1 V/μs negative slew rate exceed TL062 by 2×, allowing faster transient response in overcurrent protection comparators. |
| Industrial temperature grade | Specified from −40°C to +85°C with guaranteed parameters - eliminates derating calculations for outdoor UPS and motor control enclosures. |
Applications
| Solar String Inverter Sensing | AC Servo Drive Feedback |
|---|---|

Use Scenario: Monitoring DC-link voltage and string current in photovoltaic inverters using shunt resistors and voltage dividers. IC Role / Device Role / Timing Role: Dual-channel signal conditioning: one amplifier buffers shunt voltage (low VOS critical), the other amplifies scaled DC-link voltage. Use Value: 1.5 mV max VOS ensures ≤0.015% full-scale error in 10 V measurement range; 120 dB crosstalk prevents current-sense corruption from high-voltage rail noise. |
Use Scenario: Closed-loop current control in three-phase IGBT gate drivers, where two amplifiers condition phase-A and phase-B motor currents. IC Role / Device Role / Timing Role: Precision current sense amplifier with matched gain paths and rail-to-rail output swing capability. Use Value: 2.9 V/μs slew rate supports accurate reconstruction of 20 kHz PWM-modulated current waveforms; −40°C to +85°C rating matches servo enclosure thermal profile. |
| Single-Phase Online UPS | Industrial Sensor Signal Conditioning |
|
Use Scenario: Real-time battery voltage monitoring and inverter output waveform shaping in line-interactive UPS units. IC Role / Device Role / Timing Role: Dual op-amp implementing battery SOC estimator and sine-wave reference buffer with low THD. Use Value: 115 nV/√Hz input noise preserves resolution in 16-bit battery voltage digitization; SOIC-8 footprint fits compact UPS PCB layouts. |
Use Scenario: Amplifying microvolt-level outputs from thermocouples, RTDs, or piezoresistive pressure sensors in factory automation nodes. IC Role / Device Role / Timing Role: Low-drift, high-Z instrumentation amplifier front-end stage before programmable-gain or ADC stages. Use Value: 10.8 μV/°C tempco on VOS limits drift to <0.1 mV over 50°C span; 1 TΩ input resistance avoids loading high-Z sensor elements. |
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 | Untrimmed version: 3.5 mV max VOS (±15 V), same SOIC-8 package and pinout. | Acceptable where system calibration compensates for offset; not suitable for zero-calibration-free designs. | Select TL032CDR only if board-level trimming or digital correction is implemented - TL032AID eliminates that requirement. |
| OPA2134UA | Lower VOS (500 μV max), lower noise (8 nV/√Hz), but higher ICC (4 mA per amp) and no extended temp grade. | Better for audio or high-resolution data acquisition; unsuitable for low-power industrial battery systems. | Choose OPA2134UA only when noise and offset dominate over power and temperature - TL032AID balances all three. |
Compared with TL032CDR, TL032AID reduces worst-case offset error by 57% without layout or supply changes; versus OPA2134UA, it cuts supply current by 97% while retaining adequate bandwidth for motor control loops - making it optimal for cost-sensitive, thermally constrained industrial deployments.

FAQ
What is the maximum supply voltage rating for TL032AID?
The TL032AID has an absolute maximum supply voltage rating of ±18 V, but it is fully specified and characterized for reliable operation from ±5 V to ±15 V. Operating beyond ±15 V risks exceeding internal junction limits and invalidates parametric guarantees - always observe the Recommended Operating Conditions table in the official TL032AID datasheet.
Does TL032AID support single-supply operation?
TL032AID 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 and termination of loads to a virtual ground (e.g., TI TLE2426) are mandatory to stay within common-mode and output swing limits - refer to Figure 7-1 in the TL032AID datasheet for implementation guidance.
How does TL032AID differ from TL032ID?
TL032AID features on-chip offset-voltage trimming, resulting in tighter DC specs: 1.5 mV max VOS (vs. 3.5 mV for TL032ID) and 10.8 μV/°C tempco (vs. 11.5 μV/°C). Both share identical SOIC-8 packaging, pinout, AC performance, and −40°C to +85°C temperature range - TL032AID is the preferred choice where initial offset accuracy is critical.
What is the thermal resistance (θJA) of TL032AID in SOIC-8 package?
The TL032AID in SOIC-8 (D) package has a junction-to-ambient thermal resistance (θJA) of 86°C/W, as specified in Section 5.2 of the datasheet. This value assumes standard JEDEC 2S2P test board conditions; actual PCB layout with copper pour can reduce θJA by 15–25%, improving thermal headroom in enclosed industrial enclosures.
Can TL032AID replace TL062 in existing designs?
Yes - TL032AID is a direct functional upgrade for TL062, offering identical SOIC-8 pinout, same supply voltage range (±5 V to ±15 V), and improved specs: 2× higher slew rate, 1.1 MHz vs. 0.7 MHz bandwidth, and 50% lower input offset voltage. No PCB changes are required, though layout review for high-frequency stability is recommended due to increased bandwidth.
