Product details
Overview
TL062IDRG4 from Texas Instruments is a dual JFET-input operational amplifier designed for low-power, high-input-impedance signal conditioning in cost-sensitive analog circuits. It delivers 200 µA per amplifier supply current, 3.5 V/µs typical slew rate, ±15 V max supply voltage, and 1 MHz unity-gain bandwidth - enabling precision amplification in battery-powered and thermally constrained systems such as sensor front-ends and portable audio interfaces.
For engineers reviewing the TL062IDRG4 datasheet, TL062IDRG4 pinout, TL062IDRG4 application, or TL062IDRG4 equivalent, this page provides verified electrical specifications, SOIC-8 package details, dual-channel op amp functional context, input bias current behavior across temperature, and validated alternative options for industrial and consumer-grade designs.
Technical Context
The TL062IDRG4 implements a JFET-input differential pair with internal frequency compensation, delivering rail-to-rail common-mode input range (including VCC+) and latch-up-free operation. Its high input impedance (>10¹² Ω) and low input bias current (30–200 pA at 25°C) minimize loading on high-impedance sources like piezoelectric sensors and photodiode transimpedance stages.
It features output short-circuit protection and operates over –40°C to +85°C (I-grade), with thermal resistance RθJA = 97°C/W in SOIC-8 packaging. The device supports single-supply configurations via level-shifting input stages and maintains 120 dB crosstalk attenuation between channels - critical for dual-channel instrumentation and stereo signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables multi-stage analog signal chains in <1 mA total system supply budgets. |
| Slew Rate | 3.5 V/µs typical - supports clean amplification of audio-band signals up to ~100 kHz without distortion. |
| Input Bias Current | 30 pA (typ) at 25°C - preserves accuracy in high-Z sensor interfaces (e.g., pH electrodes, capacitive touch). |
| Unity-Gain Bandwidth | 1 MHz - sufficient for active filters, transimpedance amplifiers, and DC-coupled gain stages. |
| Common-Mode Range | Includes VCC+ - allows direct interfacing with rail-referenced sensors and single-supply DAC outputs. |
| ESD Rating | 1.5 kV HBM - meets IEC 61000-4-2 Level 2 for robustness in consumer electronics assembly and field use. |
| Input Offset Voltage | 3 mV max (C-grade) - suitable for medium-precision applications where trimming is not required. |
| CMRR / PSRR | 80 dB / 80 dB - rejects power supply ripple and common-mode noise in noisy industrial environments. |
Pinout & Package
TL062IDRG4 is supplied in an 8-pin SOIC (Small Outline Integrated Circuit) package, 4.90 mm × 6.00 mm body size, with standard 1.27 mm pitch and gull-wing leads. This RoHS-compliant surface-mount package supports automated reflow assembly and provides thermal performance suitable for ambient temperatures up to +85°C.
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 | IN– A | Inverting input for Channel A - high-impedance JFET node, sensitive to PCB leakage. |
| 3 | IN+ A | Non-inverting input for Channel A - accepts common-mode voltages up to VCC+. |
| 4 | VCC– | Negative supply rail - must be decoupled locally with 0.1 µF ceramic capacitor. |
| 5 | IN+ B | Non-inverting input for Channel B - electrically isolated from Channel A with 120 dB crosstalk rejection. |
| 6 | IN– B | Inverting input for Channel B - matched to Channel A for dual-channel differential sensing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-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), tighter VIO (10 mV max) | Better for wideband AC-coupled audio; less suitable for ultra-low-power battery operation | Select TL072CDR when bandwidth and speed outweigh power constraints. |
| TL082CDR | Higher slew rate (13 V/µs), higher input bias current (2 nA), same supply current as TL072 | Improved noise performance vs TL072 but higher input current limits high-Z sensor use | Choose TL082CDR for general-purpose dual op amp needs where moderate power is acceptable. |
Compared with TL062IDRG4, TL072CDR offers 3.7× faster response but consumes 14× more supply current, while TL082CDR trades lower input bias current stability for marginally better noise - making TL062IDRG4 optimal for power-constrained, high-impedance analog front-ends.

FAQ
What is the maximum supply voltage for TL062IDRG4?
The TL062IDRG4 supports a maximum supply voltage of ±15 V (30 V total across VCC+ and VCC–). Absolute maximum ratings specify ±18 V, but operation beyond ±15 V is not characterized or guaranteed. For reliable long-term performance, TI recommends staying within the recommended operating condition of ±5 V to ±15 V.
Does TL062IDRG4 support single-supply operation?
Yes, TL062IDRG4 supports true single-supply operation. Its common-mode input voltage range includes VCC+, allowing inputs to swing up to the positive rail. When used with a single supply (e.g., 12 V), VCC– is tied to ground, and input signals must remain within the specified VICR (e.g., –12 V to +11 V relative to VCC– at 25°C).
What is the input bias current of TL062IDRG4 at 85°C?
At TA = +85°C, the input bias current of TL062IDRG4 is specified at ≤20 nA (max) for the I-grade version. This value reflects the exponential increase in JFET junction leakage with temperature and is confirmed in Section 6.8 of the datasheet under TL062I electrical characteristics.
Is TL062IDRG4 pin-compatible with other dual op amps in SOIC-8?
TL062IDRG4 uses the industry-standard dual op amp pinout (pin 1 = OUT A, pin 2 = IN– A, pin 3 = IN+ A, pin 4 = VCC–, pin 5 = IN+ B, pin 6 = IN– B, pin 7 = OUT B, pin 8 = VCC+), matching TL072, TL082, and LM358 variants. However, functional compatibility requires verification of supply current, slew rate, and input stage architecture for the target application.
What package type is TL062IDRG4 delivered in?
TL062IDRG4 is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) with 1.27 mm lead pitch and 4.90 mm × 6.00 mm body dimensions. The "DRG4" suffix denotes tape-and-reel packaging in SOIC-8, RoHS-compliant, and green (halogen-free) construction per TI's environmental standards.
