Product details
Overview
TL062ACDRG4 from Texas Instruments is a dual JFET-input operational amplifier optimized 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, ±11 V common-mode input range (with VCC+ inclusion), and 1 MHz unity-gain bandwidth - enabling precision DC-coupled amplification and filtering in battery-powered or thermally constrained systems such as tablet audio front-ends and white-goods sensor interfaces.
For engineers reviewing the TL062ACDRG4 datasheet, TL062ACDRG4 pinout, TL062ACDRG4 application, or TL062ACDRG4 equivalent, key selection considerations include its JFET-input stage enabling picoampere-level bias current, rail-to-rail compatible common-mode range, output short-circuit protection, and SOIC-8 packaging suitable for space-constrained industrial and consumer PCB layouts.
Technical Context
The TL062ACDRG4 implements a two-stage JFET-input transconductance amplifier architecture with internal frequency compensation, delivering stable unity-gain operation without external components. Its differential pair input stage provides high input impedance (>1012 Ω) and low input bias current (30 pA typ at 25°C), while the Class-A output stage supports ±10 V output swing into 10 kΩ loads at ±15 V supplies.
Designed as a lower-power counterpart to the TL072/TL082 families, the TL062ACDRG4 maintains comparable AC performance (1 MHz GBW, 3.5 V/µs slew rate) while reducing quiescent current by ~50%. It operates across 0°C to 70°C (Commercial grade), supports ±5 V to ±15 V dual supplies, and includes integrated EMI/RF filters and 1.5 kV HBM ESD protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables dual op-amp operation from microamp-level power budgets, critical for always-on sensor signal chains. |
| Input Bias Current | 30 pA (typ, 25°C) - preserves signal integrity in high-impedance source applications (e.g., piezoelectric sensors, photodiode transimpedance stages). |
| Slew Rate | 3.5 V/µs (typ) - supports faithful reproduction of audio-band signals (<20 kHz) and fast-settling DC-coupled instrumentation paths. |
| Unity-Gain Bandwidth | 1 MHz - ensures stable closed-loop gain ≥1 with minimal phase margin degradation, validated for single-pole compensation. |
| Common-Mode Input Range | Includes VCC+ - allows direct interfacing with rail-referenced sources (e.g., DAC outputs, voltage dividers) without level-shifting circuitry. |
| Input Offset Voltage | 3 mV (max, 25°C) - enables accurate DC amplification in 12-bit system resolution contexts where offset drift <10 µV/°C is acceptable. |
| ESD Rating | 1.5 kV HBM - meets IEC 61000-4-2 Level 2 requirements for robustness in handheld and appliance-level end-equipment assembly. |
Pinout & Package
TL062ACDRG4 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.90 mm × 6.00 mm, with standard 1.27 mm pitch and gull-wing leads compatible with automated SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives feedback networks or downstream stages; internally protected against short-circuit to either supply rail. |
| 2 | IN– A | Inverting input of Amplifier A - high-impedance JFET node; requires matched trace routing to minimize CMRR degradation. |
| 3 | IN+ A | Non-inverting input of Amplifier A - accepts DC- or AC-coupled signals up to VCC+; no external offset null required for most applications. |
| 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 of Amplifier B - electrically isolated from Amplifier A; supports independent gain configurations. |
| 6 | IN– B | Inverting input of Amplifier B - identical electrical characteristics to Pin 2; crosstalk attenuation >120 dB prevents inter-channel interference. |
| 7 | OUT B | Amplifier B output - fully independent output stage; capable of sourcing/sinking equal current to Pin 1. |
| 8 | VCC+ | Positive supply rail - connects to main system +V supply; thermal resistance RθJA = 97°C/W enables operation up to 70°C ambient without heatsinking. |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | Input impedance >1012 Ω and bias current ≤200 pA enable direct connection to megohm-range sensors without loading error. |
| Low power consumption | 200 µA per amplifier allows dual op-amp integration in sub-1 mA system power envelopes, extending battery life in portable devices. |
| Output short-circuit protection | Internal current limiting prevents latch-up or permanent damage during accidental output shorts, eliminating need for external foldback circuitry. |
| Wide common-mode range | Input voltage range extends to VCC+, supporting single-supply configurations with ground-referenced inputs and rail-to-rail output swing capability. |
| Integrated EMI/RF filters | On-die filtering suppresses high-frequency noise coupling (e.g., from switching regulators or RF transceivers), improving SNR in noisy environments. |

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 supply current (2.8 mA vs 0.2 mA), 13 V/µs slew rate, tighter input offset (10 mV max), same SOIC-8 package. | Better AC performance but 14× higher power draw - suitable only when speed and precision outweigh battery life or thermal constraints. | Select TL072CDR only if system requires >10× faster settling or <10 µV/°C offset drift; otherwise TL062ACDRG4 offers superior power efficiency. |
| RC4558DR | Bipolar-input (not JFET), 1.3 mA supply current, 1.7 V/µs slew rate, 5 mV input offset, wider temp range (–40°C to 85°C). | Lacks ultra-low bias current and rail-inclusive common-mode range - unsuitable for high-Z sensor interfaces but more tolerant of input overvoltage. | Choose RC4558DR for cost-driven industrial controls where input impedance >1 MΩ is sufficient and bipolar input ruggedness is preferred. |
Compared with TL072CDR and RC4558DR, TL062ACDRG4 uniquely balances ultra-low power (200 µA), JFET-input benefits (pA bias, >1 TΩ impedance), and SOIC-8 compatibility - making it the optimal choice for battery-powered, high-impedance, and thermally sensitive dual-amplifier applications.

FAQ
What is the maximum supply voltage rating for TL062ACDRG4?
The TL062ACDRG4 has an absolute maximum supply voltage rating of ±18 V across VCC+ and VCC–. For reliable long-term operation, TI specifies recommended operating conditions of ±5 V to ±15 V. Exceeding ±15 V may increase power dissipation beyond safe limits and accelerate parameter drift, especially at elevated temperatures.
Does TL062ACDRG4 support single-supply operation?
Yes, TL062ACDRG4 supports single-supply operation due to its common-mode input voltage range extending to VCC+. When operated from a +15 V and ground supply, inputs can accept signals up to +15 V, and the output swings within ±10 V of the rails. Proper biasing of the non-inverting input (e.g., via resistor divider) is required to establish DC operating point.
What is the input offset voltage specification for TL062ACDRG4 at room temperature?
The TL062ACDRG4 has a maximum input offset voltage of 3 mV at 25°C, with a typical value of 1.5 mV. This specification applies to the "A" grade variant (TL062A), which offers tighter initial offset than the standard TL062C (6 mV max). The temperature coefficient is 10 µV/°C, resulting in ≤9 mV total offset over the full 0°C to 70°C commercial temperature range.
How does TL062ACDRG4 compare to TL072 in terms of power consumption and performance?
TL062ACDRG4 consumes only 200 µA per amplifier versus 2.8 mA for TL072 - a 14× reduction - while maintaining comparable bandwidth (1 MHz vs 3 MHz) and slew rate (3.5 V/µs vs 13 V/µs). The trade-off is lower speed and slightly higher input offset; TL062ACDRG4 is ideal where power efficiency and input impedance outweigh raw bandwidth needs.
Is TL062ACDRG4 pin-compatible with other dual op-amps in SOIC-8 packages?
TL062ACDRG4 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, RC4558, and LM833. However, differences in input stage (JFET vs bipolar), supply current, and ESD protection require verification of biasing and stability in drop-in replacements.
