Product details
Overview
TL032CPG4 from Texas Instruments is a dual 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, 120 dB CMRR, and 2.9 V/μs slew rate while consuming only 120–250 μA per amplifier at 25°C. It is used in solar inverter voltage sensing and motor drive current feedback circuits.
For engineers reviewing the TL032CPG4 datasheet, TL032CPG4 pinout, TL032CPG4 application, or TL032CPG4 equivalent, key selection criteria include its FET-input high-impedance interface (10¹² Ω), 0.69 mV typical input offset voltage (25°C, ±5 V), crosstalk attenuation of 120 dB between channels, and PDIP-8 package compatibility with legacy board layouts.
Technical Context
The TL032CPG4 implements an enhanced LinCMOS™ FET-input architecture that improves DC accuracy over the TL06x family via on-chip offset-voltage trimming-yielding 0.69 mV typical VIO at 25°C-and maintains micropower operation (120 μA/channel) without sacrificing AC performance. Its phase margin is fixed at 60° for stable unity-gain operation.
Designed explicitly for dual-supply use, it requires careful attention to common-mode input range (−11.5 V to +14 V at ±15 V supplies) and output swing limits (±12.5 V min at RL = 10 kΩ). Single-supply operation demands external DC biasing and virtual-ground referencing, such as with TI's TLE2426.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports standard dual-rail industrial rails; not rated for single-supply operation without biasing |
| Input Offset Voltage | 0.69 mV typ (25°C, ±5 V) - enables precise DC-coupled signal conditioning in sensor front-ends |
| Unity-Gain Bandwidth | 1.1 MHz - sufficient for anti-aliasing, loop compensation, and medium-speed control loops |
| Slew Rate | 2.9 V/μs (positive), 5.1 V/μs (negative) - supports fast transient response in closed-loop motor current sensing |
| CMRR | 90 dB typ (25°C, ±15 V) - rejects common-mode noise in high-impedance differential measurements |
| Input Resistance | 10¹² Ω - preserves signal integrity when interfacing with piezoelectric sensors or photodiode transimpedance stages |
| Crosstalk Attenuation | 120 dB - ensures channel isolation in dual-channel feedback paths (e.g., phase A/B current sensing) |
Pinout & Package
TL032CPG4 is housed in an 8-pin plastic DIP (PDIP-8) package measuring 9.81 mm × 9.43 mm, with through-hole mounting and industry-standard lead pitch (2.54 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, channel 1 | Amplified output of first op-amp; drives feedback networks or ADC inputs |
| 1IN– | Inverting Input, channel 1 | High-impedance node for negative feedback configuration; sensitive to PCB leakage |
| 1IN+ | Non-Inverting Input, channel 1 | High-Z input for reference or sensor signals; requires matched trace impedance |
| VCC– | Power supply negative | Ground reference for dual-supply operation; must be decoupled locally with 0.1 μF ceramic |
| 2IN+ | Non-Inverting Input, channel 2 | Independent second input path; no internal coupling to channel 1 |
| 2IN– | Inverting Input, channel 2 | Separate inverting node; used for differential pair or independent gain stage |
| 2OUT | Output, channel 2 | Second independent output; shares same supply pins but isolated signal path |
| VCC+ | Power supply positive | Positive rail connection; requires local 0.1 μF bypass capacitor near pin |
Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | 10¹² Ω input resistance enables direct interface with high-Z sources (e.g., pH electrodes, strain gauges) |
| On-chip offset trimming | 0.69 mV typical VIO (TL032C) reduces calibration burden in precision analog front-ends |
| Dual-channel integration | Two fully independent amplifiers in one PDIP-8 package save board space vs. discrete TL031 solutions |
| Micropower operation | 120 μA per amplifier at 25°C allows battery-backed or energy-harvesting system use |
| Stable unity-gain configuration | 60° phase margin ensures unconditional stability without external compensation components |

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 |
|---|---|---|---|
| TL072CDR | Higher slew rate (13 V/μs), lower input offset (3 mV max), but higher supply current (1.4 mA/channel) | Better for wideband audio or fast control loops; unsuitable for ultra-low-power designs | Select TL072CDR when bandwidth >3 MHz and power budget >1 mA/channel is acceptable |
| TL062CDR | Lower power (200 μA/channel), but higher input offset (15 mV max) and slower slew rate (3.5 V/μs) | Acceptable for cost-sensitive, non-precision applications where offset drift is managed externally | Choose TL062CDR only if offset calibration is implemented in firmware or external circuitry |
Compared with TL032CPG4, TL072CDR trades micropower operation for speed and precision, while TL062CDR sacrifices DC accuracy to reduce quiescent current-making TL032CPG4 the optimal balance for industrial sensing where both low power and low offset are required.

FAQ
What is the operating temperature range for TL032CPG4?
The TL032CPG4 is characterized for operation from 0°C to 70°C (C-suffix grade). It meets all electrical specifications across this range, including input offset voltage (max 4.5 mV), supply current (120–250 μA/channel), and CMRR (min 70 dB). Operation outside this range is not guaranteed and may impact long-term reliability.
Can TL032CPG4 be used with a single supply?
No, TL032CPG4 is designed exclusively for dual-supply operation (±5 V to ±15 V). Using it with a single supply violates the common-mode input voltage and output swing specifications. For single-supply applications, TI recommends the TLC-series LinCMOS op-amps (e.g., TLC272), which are specified for rail-to-rail or near-rail operation.
What is the maximum load capacitance TL032CPG4 can drive without instability?
TL032CPG4 is tested and specified for stable unity-gain operation with CL ≤ 100 pF and RL = 10 kΩ. Driving larger capacitive loads (e.g., >200 pF) risks peaking or oscillation due to phase margin degradation. For heavier loads, add a series resistor (≥100 Ω) between the output and capacitance to isolate the pole.
Does TL032CPG4 have ESD protection diodes on its inputs?
Yes, TL032CPG4 includes internal ESD protection diodes from each input to the supply rails. These diodes clamp transient voltages exceeding VCC+ or falling below VCC– by ~0.7 V. To avoid forward-biasing them, ensure input signals remain within the absolute maximum ratings: −0.3 V to (VCC+ + 0.3 V) relative to VCC–.
How does TL032CPG4 compare to TL032AC in terms of offset voltage?
TL032CPG4 (C-grade) has a typical input offset voltage of 0.69 mV at 25°C, while TL032AC (A-grade) achieves 0.53 mV typical under identical conditions. The A-grade variant uses tighter trimming, resulting in lower initial offset and reduced temperature drift (11.5 μV/°C vs. 11.4 μV/°C), making it preferable for high-accuracy instrumentation where calibration headroom is limited.
