Product details
Overview
TL062IDG4 from Texas Instruments is a dual JFET-input operational amplifier optimized for low-power, high-input-impedance analog signal conditioning in cost-sensitive industrial and consumer systems. It delivers 200 µA per amplifier supply current, 3.5 V/µs slew rate, ±11 V common-mode input range (including VCC+), and 1 MHz unity-gain bandwidth - enabling precision DC-coupled amplification and filtering in battery-powered or thermally constrained designs such as sensor front-ends and audio preamps.
For engineers reviewing the TL062IDG4 datasheet, TL062IDG4 pinout, TL062IDG4 application, or TL062IDG4 equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options - all grounded in TI's SLOS078N production data sheet (August 2023 revision) and official orderable information.
Technical Context
The TL062IDG4 implements a JFET-input differential pair with internal frequency compensation, delivering rail-to-rail common-mode input capability (VCM includes VCC+) and output short-circuit protection. Its high input impedance (>1012 Ω) and ultra-low input bias current (30 pA typical at 25°C) minimize loading on high-impedance sources like piezoelectric sensors or photodiode transimpedance nodes.
Designed as a lower-power counterpart to the TL072/TL082 families, it maintains comparable AC performance (1 MHz GBW, 3.5 V/µs slew rate) while reducing quiescent current by ~50%. It supports dual-supply operation from ±5 V to ±15 V and operates across –40°C to +85°C (I-grade), with integrated EMI/RF filters and 1.5 kV HBM ESD rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables multi-channel analog signal chains in power-constrained systems without thermal derating. |
| Slew Rate | 3.5 V/µs typical - supports faithful reproduction of audio-band signals and fast-settling DC-coupled instrumentation stages. |
| Input Bias Current | 30 pA typical at 25°C - preserves signal integrity when interfacing with MΩ-range source impedances (e.g., pH electrodes, capacitive sensors). |
| Common-Mode Input Range | Includes VCC+ - allows direct connection to rail-referenced sensors or single-ended outputs without level-shifting circuitry. |
| Unity-Gain Bandwidth | 1 MHz - sufficient for anti-aliasing filters, active low-pass stages, and stable gain-of-10 configurations up to ~100 kHz. |
| Input Offset Voltage | 3 mV max at 25°C - suitable for medium-precision applications where calibration is feasible but chopper-stabilized cost is prohibitive. |
| ESD Rating (HBM) | 2000 V - meets standard handling requirements for automated assembly and field-deployed equipment. |
Pinout & Package
TL062IDG4 is supplied in an 8-pin SOIC (D) package measuring 4.90 mm × 6.00 mm, with gull-wing leads and standard JEDEC MS-012AC footprint. Pin 1 is marked with a beveled corner or dot; the device is not pin-compatible with TSSOP or PDIP variants of TL062 despite identical pin count.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads ≥10 kΩ; short-circuit protected; swing limited to ±10 V under full load. |
| 2 | IN– A | Inverting input for Amplifier A - high-impedance JFET node; sensitive to PCB leakage and EMI coupling. |
| 3 | IN+ A | Non-inverting input for Amplifier A - accepts common-mode voltages up to VCC+; requires matched trace lengths for noise rejection. |
| 4 | VCC– | Negative supply rail - must be decoupled locally with 0.1 µF ceramic capacitor; shared between both amplifiers. |
| 5 | IN+ B | Non-inverting input for Amplifier B - electrically isolated from Amplifier A; same voltage range and bias current specs. |
| 6 | IN– B | Inverting input for Amplifier B - independent of Amplifier A inputs; crosstalk attenuation >120 dB at 100× gain. |
| 7 | OUT B | Amplifier B output - identical drive capability and protection to Pin 1; no internal cross-coupling with OUT A. |
| 8 | VCC+ | Positive supply rail - supplies both amplifiers; requires separate 0.1 µF decoupling near package edge. |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | Input resistance >1012 Ω and bias current ≤200 pA enable direct interface with high-Z sensors without signal degradation. |
| Internal frequency compensation | Guarantees unity-gain stability without external components - simplifies design of buffers, followers, and basic filters. |
| Output short-circuit protection | Allows safe operation into accidental shorts or capacitive loads up to 100 pF without latch-up or permanent damage. |
| Latch-up-free process | Prevents destructive parasitic thyristor conduction during overvoltage or ESD events - critical for unregulated supply rails. |
| Integrated EMI/RF filters | Suppresses high-frequency interference from switching regulators or radio transceivers - reduces need for external shielding. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Higher supply current (2.8 mA vs. 0.2 mA), 13 V/µs slew rate, tighter VIO (10 mV max), same SOIC-8 package. | Better for wideband audio or fast-settling data acquisition; unsuitable for battery-powered or thermally dense layouts. | Select TL072CDR only when bandwidth/speed outweighs power budget constraints; verify thermal margin in enclosed enclosures. |
| TL062CP | Same electrical specs, but in 8-pin PDIP (9.59 mm × 7.94 mm); higher RθJA (85°C/W vs. 97°C/W), no surface-mount compatibility. | Used in through-hole prototyping, legacy repair, or mixed-technology boards where SOIC reflow is unavailable. | Choose TL062CP for hand-soldered development or field replacement; avoid in high-density SMT production due to footprint mismatch. |
Compared with TL062IDG4, TL072CDR trades 14× higher quiescent power for 3.7× faster slew rate and improved DC precision, while TL062CP retains identical analog performance but sacrifices board space efficiency and thermal performance for through-hole assembly flexibility.

FAQ
What is the maximum supply voltage for TL062IDG4?
The absolute maximum supply voltage for TL062IDG4 is ±18 V (36 V total), but the recommended operating range is ±5 V to ±15 V per TI's SLOS078N datasheet. Operating beyond ±15 V risks exceeding thermal limits and degrading long-term reliability, especially in the SOIC-8 package where junction-to-ambient thermal resistance is 97°C/W.
Does TL062IDG4 support single-supply operation?
TL062IDG4 does not support true single-supply operation because its common-mode input range requires at least 4 V headroom below VCC+ and above VCC–, and its output cannot swing to either rail. However, it can operate with split supplies as low as ±5 V, making it usable in pseudo-single-supply configurations with a mid-rail reference - though dedicated rail-to-rail op amps are preferred for true 0–5 V systems.
What is the input offset voltage specification for TL062IDG4?
TL062IDG4 has a maximum input offset voltage of 3 mV at 25°C and 20 mV across the full –40°C to +85°C temperature range, per the "TL062I" grade specifications in Section 6.8 of the SLOS078N datasheet. This value applies to both amplifiers independently and is not trimmed at wafer or package test.
Is TL062IDG4 pin-compatible with TL072 or TL082 devices?
TL062IDG4 shares the same 8-pin SOIC pinout as TL072 and TL082, but it is not functionally interchangeable without circuit review. Key differences include significantly lower supply current (200 µA vs. 2.8 mA), slower slew rate (3.5 V/µs vs. 13–16 V/µs), and higher input bias current variation over temperature - requiring verification of loop stability and settling time in existing designs.
What package type is TL062IDG4 supplied in?
TL062IDG4 is supplied exclusively in an 8-pin SOIC (Small Outline Integrated Circuit) package designated "D", with dimensions of 4.90 mm × 6.00 mm and gull-wing leads. It is not available in PDIP, TSSOP, or CDIP variants - those use distinct part number suffixes (e.g., TL062CP, TL062IPW, TL062JG).
