Product details
Overview
TL032ACDR 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, 1.5 mV max input offset voltage (25°C), and 2.9 V/μs typical slew rate - enabling accurate amplification of high-impedance sensor outputs in solar inverters and motor drive feedback loops.
For engineers reviewing the TL032ACDR datasheet, TL032ACDR pinout, TL032ACDR application, or TL032ACDR equivalent, this page provides verified electrical specifications, SOIC-8 package layout, real-world use cases in AC drive control and UPS monitoring, and validated alternative parts with documented parameter differences.
Technical Context
The TL032ACDR implements enhanced LinCMOS FET-input architecture to achieve higher input impedance (>1 TΩ) and lower input bias current (<200 pA at 70°C) than bipolar-input op-amps, making it suitable for interfacing with piezoelectric sensors and photodiode transimpedance stages. Its on-chip offset-voltage trimming ensures tight DC accuracy without external nulling circuitry.
Designed for dual-supply operation, the device requires attention to common-mode input voltage limits (e.g., −11.5 V to +14 V at ±15 V supplies) and output swing constraints (±14.955 V into 10 kΩ). Single-supply use demands DC biasing and virtual-ground generation via TI's TLE2426 or equivalent.
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 | Max 1.5 mV at 25°C - enables sub-mV error budgets in precision instrumentation front-ends |
| Unity-Gain Bandwidth | 1.1 MHz - sufficient for anti-aliasing, loop compensation, and medium-speed sensor signal conditioning |
| Slew Rate | 2.9 V/μs (typical) - handles fast transient signals in motor current sensing without distortion |
| Common-Mode Rejection | 94 dB (min) - rejects noise coupling from shared ground paths in noisy power electronics environments |
| Input Bias Current | 200 pA (max at 70°C) - preserves signal integrity when driving from MΩ-range source impedances |
| Supply Current per Amp | 280 μA (max at ±15 V) - enables battery-backed or energy-harvesting system designs with ultra-low quiescent power |
Pinout & Package
TL032ACDR is supplied in an 8-pin SOIC (D) package measuring 4.9 mm × 6.0 mm, compliant with JEDEC MS-012, with gull-wing leads and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, channel 1 | Amplified output signal for first op-amp stage; drives loads ≥10 kΩ for full swing performance |
| 1IN− | Inverting Input, channel 1 | Differential input node for negative feedback configuration; high-impedance FET input (≥1 TΩ) |
| 1IN+ | Non-Inverting Input, channel 1 | Reference or signal input node; accepts common-mode voltages up to ±14 V at ±15 V supply |
| VCC− | Power supply negative | Ground reference for negative rail; 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 with 120 dB crosstalk attenuation |
| 2IN− | Inverting Input, channel 2 | Second differential input; identical DC and AC specs to channel 1 for matched dual-channel operation |
| 2OUT | Output, channel 2 | Second independent output; usable for parallel gain stages or differential output generation |
| VCC+ | Power supply positive | Positive rail connection; requires local 0.1 μF ceramic decoupling to minimize supply-induced noise |
Key Features
| Feature | Design Value |

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 (3.5 V/μs), no on-chip trimming | Acceptable where cost is critical and DC accuracy <5 mV is sufficient | Choose TL062CDR only if VIO >5 mV and long-term drift tolerance allow relaxed calibration intervals |
| TLC272CDR | Lower supply current (110 μA), wider VCC range (3–16 V single-supply), but reduced CMRR (80 dB) | Better suited for battery-powered portable instruments with single-rail constraints | Select TLC272CDR when operating from 3.3 V or 5 V single supply and CMRR >85 dB is not required |
Compared with TL032ACDR, TL062CDR trades DC precision for lower cost, while TLC272CDR offers superior power efficiency and single-supply flexibility at the expense of common-mode noise immunity - making TL032ACDR optimal for dual-supply industrial signal chains demanding both accuracy and robustness.

FAQ
What is the maximum operating temperature range for TL032ACDR?
The TL032ACDR is characterized for operation from 0°C to 70°C (C-suffix grade). Its absolute maximum junction temperature is 150°C, and thermal resistance θJA is 86°C/W in SOIC-8 package. For extended temperature applications (−40°C to 85°C), the TL032IDR or TL032AIDR variants are specified and recommended instead of TL032ACDR.
Can TL032ACDR operate from a single 5-V supply?
TL032ACDR is designed for dual-supply operation and is not characterized for single-supply use. While functional with proper input biasing and virtual-ground referencing (e.g., using TI's TLE2426), its common-mode input range and output swing are guaranteed only under ±5 V or ±15 V conditions. For native single-supply applications, TI recommends the TLC272 or TLV2462 families instead of TL032ACDR.
What is the input offset voltage specification for TL032ACDR at full temperature range?
For TL032ACDR, the input offset voltage is specified as 3.8 mV maximum over the full 0°C to 70°C operating range. At 25°C, the typical value is 0.53 mV with a maximum of 2.8 mV. The temperature coefficient is 11.5 μV/°C, contributing to predictable drift behavior in thermally varying environments.
Does TL032ACDR support rail-to-rail input or output?
No, TL032ACDR does not support rail-to-rail input or output. Its common-mode input voltage range is limited to −11.5 V to +14 V at ±15 V supplies, and output swing is ±14.955 V into 10 kΩ - meaning it cannot reach within ~0.05 V of either rail. For rail-to-rail performance, consider TI's TLV2462 or OPA2333 families instead of TL032ACDR.
How is crosstalk between the two amplifiers in TL032ACDR specified?
TL032ACDR specifies 120 dB minimum crosstalk attenuation between channels at AVD = 100 dB. This means a 1 V signal on one amplifier's output induces less than 1 μV of coupled error at the other amplifier's output - ensuring independent operation in dual-channel configurations such as differential signal processing or multi-loop control where channel isolation is essential.
