Product details
Overview
TL032IDRG4 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 or ±5 V dual-supply operation, 2.9 V/μs slew rate (positive), 1.5 mV max input offset voltage (at 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 TL032IDRG4 datasheet, TL032IDRG4 pinout, TL032IDRG4 application, or TL032IDRG4 equivalent, this page provides verified specifications, SOIC-8 package details, real-world use cases in AC servo control and string inverter sensing, and validated alternative options for design continuity and supply resilience.
Technical Context
The TL032IDRG4 uses Texas Instruments' enhanced FET process to achieve improved DC accuracy (on-chip offset trimming) and AC performance (higher slew rate and bandwidth) over legacy TL06x amplifiers - without increasing quiescent current. Its 10¹² Ω input resistance and 4 pF input capacitance support high-impedance sensor interfacing with minimal loading.
Designed for dual-supply operation, it 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 RL = 10 kΩ). Single-supply use demands external DC biasing and virtual-ground referencing via devices 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 circuitry |
| Input Offset Voltage (max) | 1.5 mV at 25°C, ±15 V - enables sub-10-bit error in 12-bit ADC front-ends without trimming |
| Unity-Gain Bandwidth | 1.1 MHz - sufficient for anti-aliasing and closed-loop control up to ~100 kHz |
| Slew Rate (positive) | 2.9 V/μs - allows clean 10 Vpp signals up to ~45 kHz before slew-induced distortion |
| Input Bias Current | 200 pA max at 25°C - preserves signal integrity when driving from MΩ-range sources (e.g., piezoelectric sensors) |
| Crosstalk Attenuation | 120 dB - ensures channel isolation critical in dual-path feedback or differential measurement topologies |
| Operating Temperature | −40°C to +85°C - qualified for industrial motor drives and outdoor solar inverter environments |
Pinout & Package
TL032IDRG4 is housed in an 8-pin SOIC (D package), 4.9 mm × 6.0 mm body size, with gull-wing leads and surface-mount compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, channel 1 | Amplified output of first op-amp; rail-to-rail swing limited by supply and load |
| 1IN– | Inverting Input, channel 1 | Differential input node; high-impedance FET gate requiring guarded layout |
| 1IN+ | Non-inverting Input, channel 1 | Reference input for follower or non-inverting gain configurations |
| VCC– | Power supply negative | Negative rail connection; must be decoupled locally with 0.1 μF ceramic capacitor |
| 2IN+ | Non-inverting Input, channel 2 | Independent second amplifier input; electrically isolated from channel 1 except via substrate |
| 2IN– | Inverting Input, channel 2 | Second differential pair input; shares same process characteristics as channel 1 |
| 2OUT | Output, channel 2 | Second independent output; 120 dB crosstalk ensures minimal inter-channel coupling |
| VCC+ | Power supply positive | Positive rail connection; symmetric dual supply required for full spec compliance |
Key Features
| Feature | Design Value |
|---|---|
| On-chip offset-voltage trimming | Reduces initial VIO to ≤1.5 mV (TL032I grade), cutting calibration overhead in production test |
| FET-input architecture | 10¹² Ω input resistance enables direct interface with high-Z sources (e.g., pH electrodes, photodiodes) |
| Low quiescent current | 250 μA per amplifier max at 25°C supports battery-backed or energy-harvesting subsystems |
| Enhanced slew rate vs. TL062 | 2.9 V/μs (vs. 3.5 V/μs for TL062) with identical 200 μA ICC - improves transient response without power penalty |
| Industrial temperature range | −40°C to +85°C operation validated per JEDEC JESD22-A108 - suitable for uncontrolled ambient deployments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel FET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Higher slew rate (13 V/μs), higher input bias current (2 nA), no on-chip offset trim (max VIO = 10 mV) | Better for wideband AC-coupled audio; less suitable for precision DC-coupled sensor front-ends | Select when bandwidth >5 MHz is required and offset calibration is acceptable |
| OPA2134PA | Lower noise (8 nV/√Hz), lower VIO (0.5 mV), higher ICC (4 mA), SO-8 package | Optimized for audio and high-fidelity instrumentation; not qualified for −40°C to +85°C | Choose for ultra-low-noise, low-distortion applications where industrial temp range is not mandatory |
Compared with TL032IDRG4, TL072CDR trades DC precision for speed and cost, while OPA2134PA delivers superior noise and offset performance at significantly higher power and narrower temperature qualification - making TL032IDRG4 the optimal balance for industrial-grade, low-power, dual-channel precision amplification.

FAQ
What is the maximum supply voltage rating for TL032IDRG4?
The absolute maximum supply voltage for TL032IDRG4 is ±18 V, but it is fully specified and characterized only from ±5 V to ±15 V. Operation beyond ±15 V risks exceeding recommended operating conditions and may degrade long-term reliability or cause parametric shift - always refer to Section 5.1 Absolute Maximum Ratings in the official TI datasheet for derating guidance.
Does TL032IDRG4 support single-supply operation?
TL032IDRG4 is designed for dual-supply operation and does not feature rail-to-rail input or output stages. For single-supply use, external DC biasing of inputs and a virtual-ground reference (e.g., using TI's TLE2426) are mandatory to maintain common-mode voltage within −1.5 V to +14 V (at ±15 V equiv.) and avoid clipping or phase reversal - consult TI Application Report SLOA058 for implementation examples.
What is the input offset voltage specification for TL032IDRG4 at 85°C?
For TL032IDRG4 (I-suffix, −40°C to +85°C grade), the input offset voltage is specified at 5.3 mV maximum across full temperature range, with a typical value of 0.69 mV at 25°C and 3.3 mV max at 85°C per Section 5.10 of the datasheet - confirming stable DC performance in high-ambient motor drive enclosures.
How does TL032IDRG4 compare to TL062 in terms of power consumption?
TL032IDRG4 draws 250 μA per amplifier maximum at 25°C, matching the TL062's quiescent current while delivering higher slew rate (2.9 V/μs vs. 3.5 V/μs) and lower input offset voltage (1.5 mV vs. 15 mV). This makes TL032IDRG4 a true drop-in upgrade for TL062 designs where precision and speed improvements are needed without increasing system power budget.
Is TL032IDRG4 pin-compatible with other TL03x variants in SOIC-8?
Yes - TL032IDRG4 shares identical pinout and footprint with TL032CDR, TL032ACDR, and TL032IDR in the SOIC-8 (D) package, as confirmed in Figure 4-3 and Table 4-3 of the datasheet. All TL032x SOIC-8 variants use the same 1OUT/1IN–/1IN+/VCC–/2IN+/2IN–/2OUT/VCC+ assignment, enabling seamless substitution within the same temperature grade.
