Product details
Overview
TL062CPWG4 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 slew rate, and ±11 V common-mode input range extending to VCC+, enabling use in battery-powered sensor interfaces and audio preamplifiers.
For engineers reviewing the TL062CPWG4 datasheet, TL062CPWG4 pinout, TL062CPWG4 application, or TL062CPWG4 equivalent, key selection criteria include its JFET-input architecture for pA-level bias current, rail-to-rail-compatible input stage, output short-circuit protection, and TSSOP-8 packaging for space-constrained PCB layouts.
Technical Context
The TL062CPWG4 implements a two-stage JFET-input op amp topology with internal frequency compensation, delivering unity-gain stability without external components. Its differential pair input stage provides high common-mode rejection (80 dB min) and supply-voltage rejection (80 dB min), while the Class AB output stage supports ±10 V output swing into 10 kΩ at ±15 V supplies.
Designed as a low-power counterpart to the TL072 and TL082 families, the TL062CPWG4 maintains comparable bandwidth (1 MHz unity-gain) and noise performance (30 nV/√Hz at 1 kHz) while reducing quiescent current by ~50%. It operates across –40°C to +85°C (I-grade) and features integrated EMI/RF filtering for robustness in noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables multi-channel operation on microampere-scale power budgets |
| Slew Rate | 3.5 V/µs typical - supports audio-band signal fidelity and fast transient response |
| Input Bias Current | 30 pA typical at 25°C - preserves signal integrity in high-impedance sensor and photodiode interfaces |
| Common-Mode Range | –12 V to +15 V (with ±15 V supplies) - includes VCC+, simplifying single-supply design with level-shifting |
| Input Resistance | 1012 Ω - minimizes loading of passive filters and high-Z transducers |
| Unity-Gain Bandwidth | 1 MHz - suitable for active filters, instrumentation amplifiers, and precision DC-coupled gain stages |
| ESD Rating | 1.5 kV CDM - meets industrial handling requirements without additional board-level protection |
Pinout & Package
Texas Instruments TL062CPWG4 is housed in an 8-pin TSSOP package (PW), measuring 3.00 mm × 6.40 mm, with exposed pad not electrically connected. The package supports fine-pitch surface-mount assembly and offers thermal resistance RθJA = 149 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to ±10 V swing into ≥10 kΩ |
| 2 | IN– A | Inverting input for amplifier A - high-impedance JFET node, sensitive to layout-induced leakage |
| 3 | IN+ A | Non-inverting input for amplifier 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 amplifier B - electrically isolated from amplifier A except via shared supply rails |
| 6 | IN– B | Inverting input for amplifier B - crosstalk attenuation >120 dB ensures channel independence |
| 7 | OUT B | Amplifier B output - identical electrical specs to OUT A; no internal interconnection |
| 8 | VCC+ | Positive supply rail - supports ±5 V to ±15 V operation; requires local 0.1 µF bypass |
Key Features
| Feature | Design Value |
|---|---|
| Very low power consumption | 200 µA per amplifier enables dual-op-amp operation under 500 µA total - critical for portable and energy-harvesting systems |
| JFET-input stage | 1012 Ω input resistance and 30 pA bias current preserve signal integrity in pH probes, piezoelectric sensors, and capacitive touch interfaces |
| Output short-circuit protection | Enables safe operation during prototyping, test jig connection errors, or transient overloads without latch-up or permanent damage |
| Wide common-mode voltage range | Includes VCC+, allowing direct interface to signals referenced to positive rail - eliminates level-shifter ICs in single-supply configurations |
| Internal frequency compensation | Guarantees unity-gain stability without external compensation components - reduces BOM count and layout complexity |

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), faster slew rate (13 V/µs), lower noise (18 nV/√Hz) | Better suited for wideband audio or high-speed data acquisition where power is secondary to performance | Select TL072CDR when bandwidth >3 MHz or noise <20 nV/√Hz is required; avoid in battery-powered designs |
| TL082CDR | Higher input bias current (300 pA vs 30 pA), same supply current as TL072, no EMI/RF filtering | Lower cost alternative where moderate input impedance suffices and ESD robustness is less critical | Choose TL082CDR for cost-driven consumer electronics with stable PCB environments and no RF exposure |
Compared with TL072CDR and TL082CDR, the TL062CPWG4 trades bandwidth and raw speed for ultra-low power and superior input impedance - making it the only viable option among the three for multi-year battery operation and femtoampere-level sensor interfacing.

FAQ
What is the operating temperature range for the TL062CPWG4?
The TL062CPWG4 is rated for operation from –40°C to +85°C (I-grade). This range is validated per TI's recommended operating conditions and supports deployment in industrial control panels, home appliance mainboards, and outdoor sensor nodes without derating. The device maintains specified input offset voltage, slew rate, and CMRR across this full span.
Does the TL062CPWG4 require external compensation components?
No, the TL062CPWG4 includes internal frequency compensation and is unity-gain stable. Engineers can configure it as a voltage follower, inverting amplifier, or active filter without adding external capacitors or resistors for stability - reducing bill-of-materials cost and PCB area while ensuring predictable phase margin.
Can the TL062CPWG4 drive capacitive loads directly?
The TL062CPWG4 is not optimized for direct capacitive load driving above 100 pF. For loads exceeding this (e.g., long cables or ADC input capacitance), a series resistor (20–100 Ω) between the output and load is recommended to maintain stability and prevent ringing. This limitation stems from its internal compensation tailored for resistive loads.
How does the input offset voltage of the TL062CPWG4 compare to the TL072?
The TL062CPWG4 has a maximum input offset voltage of 6 mV (TL062C grade), while the TL072CDR specifies 10 mV max. Though both are JFET-input op amps, the TL062CPWG4 achieves tighter initial offset due to process optimization for cost-sensitive precision - making it preferable in DC-coupled gain stages where offset drift dominates error budget.
Is the TL062CPWG4 pin-compatible with other dual op amps in TSSOP-8 packages?
Yes, the TL062CPWG4 uses the industry-standard dual op amp pinout (SOIC-8/TSSOP-8): 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+. This allows drop-in replacement with TL072CDR, TL082CDR, and RC4558P variants in existing TSSOP-8 footprints.
