Product details
Overview
TL032IDR from Texas Instruments is a dual-channel, JFET-input operational amplifier optimized for low-power, precision DC and AC signal conditioning in industrial and energy systems. It delivers 1.1 MHz unity-gain bandwidth, ±15 V operation, 120 dB CMRR, 1.5 mV max input offset voltage (at 25°C), and 2.9 V/μs typical slew rate - all at only 250 μA per amplifier supply current.
For engineers reviewing the TL032IDR datasheet, TL032IDR pinout, TL032IDR application, or TL032IDR equivalent, this device is selected for high-impedance sensor interfacing, solar inverter feedback loops, and motor drive control amplifiers where micropower operation and FET-input stability are critical.
Technical Context
The TL032IDR uses Texas Instruments' enhanced FET process to achieve improved AC performance over TL06x predecessors without increasing quiescent current. Its dual-channel architecture supports independent signal paths with 120 dB crosstalk attenuation, enabling compact multi-loop control designs.
Designed for dual-supply operation (±5 V to ±15 V), it features rail-to-rail compatible output swing (±14.955 V at ±15 V), common-mode input range extending to within 1.5 V of rails, and integrated offset-voltage trimming for stable DC accuracy across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports standard industrial dual-rail supplies without external regulation |
| Input Offset Voltage | Max 1.5 mV at 25°C - enables accurate low-level signal amplification without manual nulling |
| Unity-Gain Bandwidth | 1.1 MHz - sufficient for anti-aliasing, current sensing, and closed-loop control up to ~100 kHz |
| Slew Rate | 2.9 V/μs (typ) - supports fast transient response in motor current feedback and UPS regulation |
| CMRR | Min 75 dB (up to 94 dB typ) - rejects noise in high-common-mode environments like inverter DC-link monitoring |
| Supply Current | 250 μA per amplifier (max) - enables battery-backed or energy-harvesting system integration |
| Input Impedance | 10¹² Ω - preserves signal integrity when driving from high-Z sources (e.g., piezoelectric sensors) |
Pinout & Package
TL032IDR is housed in an 8-pin SOIC (D package), 4.9 mm × 6.0 mm body size, with gull-wing leads and standard JEDEC MS-012AC footprint.

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 supply current (2.8 mA), no on-chip offset trim | Better for wideband audio or fast transient response; unsuitable for ultra-low-power designs | Select TL072CDR only when bandwidth >3 MHz is required and power budget allows 10× higher ICC |
| OPA2134PA | Lower noise (8 nV/√Hz), lower VIO (0.5 mV), higher cost, SO-8 package | Preferred for high-fidelity audio or metrology-grade signal chains where noise dominates error budget | Choose OPA2134PA when total input-referred noise must be <10 nV/√Hz and VIO <0.5 mV is mandatory |
Compared with TL072CDR and OPA2134PA, TL032IDR uniquely balances micropower operation (250 μA), FET-input impedance, and trimmed DC accuracy - making it optimal for cost-sensitive, thermally constrained industrial controls where 1.1 MHz bandwidth suffices.

FAQ
What is the maximum operating supply voltage for TL032IDR?
The TL032IDR supports absolute maximum supply voltages of ±18 V, but is fully specified and characterized for reliable operation from ±5 V to ±15 V. Operation at ±18 V exceeds recommended conditions and may reduce long-term reliability or parametric consistency. For designs requiring ±15 V rails, TL032IDR delivers full performance including 120 dB CMRR and 2.9 V/μs slew rate - confirmed in TI's SLOS180D datasheet Section 5.1 and 5.3.
Does TL032IDR support single-supply operation?
TL032IDR is designed for dual-supply operation and does not feature rail-to-rail input or output. When used in single-supply configurations, external DC biasing of inputs and virtual-ground generation (e.g., using TI's TLE2426) are mandatory to maintain linear operation within common-mode and output swing limits. The datasheet explicitly states that "DC biasing of the input signal is required" and recommends LinCMOS alternatives (TLC prefix) for native single-supply use - confirming TL032IDR's dual-rail dependency.
What is the input offset voltage specification for TL032IDR over temperature?
For TL032IDR (I-suffix, –40°C to +85°C grade), the input offset voltage is specified at 25°C as ≤1.5 mV (TL032AI variant) or ≤3.3 mV (TL032I variant), with a temperature coefficient of 11.4 μV/°C. Over full temperature range, max VIO reaches 4.6 mV (TL032AI) or 5.3 mV (TL032I), per Sections 5.10 and 5.11 of the SLOS180D datasheet. This trimmed performance differentiates TL032IDR from non-A variants and legacy TL062.
How does TL032IDR compare to TL062 in terms of power and speed?
TL032IDR consumes ≤250 μA per amplifier - identical to TL062 - yet achieves 2.9 V/μs slew rate and 1.1 MHz unity-gain bandwidth, versus TL062's 3.5 V/μs and 1.5 MHz. However, TL032IDR adds on-chip offset trimming (1.5 mV vs. TL062's 15 mV) and higher CMRR (94 dB vs. 70 dB), delivering superior DC accuracy without sacrificing AC response - fulfilling its role as a "direct upgrade" per TI's official description in Section 1.
Is TL032IDR pin-compatible with other TL03x variants?
Yes, TL032IDR shares the same 8-pin SOIC (D) package and pinout as TL032CDR, TL032ACDR, and TL032IP. All TL032x variants use identical pin mapping: pins 1/7 = OUT1/OUT2, 2/6 = IN–1/IN–2, 3/5 = IN+1/IN+2, 4 = VCC–, 8 = VCC+. This allows drop-in replacement between C/I/A suffixes when thermal and accuracy requirements align - verified in Figure 4-3 and Table 4-3 of the SLOS180D datasheet.
