Product details
Overview
TL062CPSR 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 amplification in battery-powered and thermally constrained systems such as sensor front-ends and portable audio preamps.
For engineers reviewing the TL062CPSR datasheet, TL062CPSR pinout, TL062CPSR application, or TL062CPSR equivalent, key selection criteria include its JFET-input stage (1012 Ω input resistance), rail-to-rail-compatible common-mode range, low 30 nV/√Hz input voltage noise at 1 kHz, and guaranteed operation from 0°C to 70°C with ±5 V to ±15 V dual supplies.
Technical Context
The TL062CPSR implements a two-stage JFET-input transconductance amplifier architecture with internal frequency compensation, delivering stable unity-gain operation without external components. Its differential pair uses matched JFETs to achieve ultra-low input bias currents (30 pA typ. at 25°C) and low input offset current (5 pA typ.), critical for high-impedance source interfacing.
Designed as a low-power counterpart to the TL072 and TL082 families, it maintains comparable AC performance (1 MHz GBW, 3.5 V/µs slew rate) while reducing quiescent current by ~50%. It supports single-supply operation via level-shifting input stages and includes output short-circuit protection and latch-up-free process technology.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables dual op-amp operation from microamp-level power budgets, suitable for always-on sensor nodes. |
| Input Resistance | 1012 Ω - preserves signal integrity when amplifying from high-impedance sources like piezoelectric sensors or pH electrodes. |
| Slew Rate | 3.5 V/µs typical - supports clean amplification of audio-band signals (≤100 kHz) without distortion under load. |
| Unity-Gain Bandwidth | 1 MHz - allows stable closed-loop gain configurations up to ×10 at 100 kHz, sufficient for anti-aliasing and active filtering. |
| Input Voltage Noise | 30 nV/√Hz at 1 kHz - ensures minimal added noise in low-level signal chains where SNR is critical. |
| Common-Mode Range | Includes VCC+ - permits direct interface with rail-referenced sensors and simplifies biasing in single-supply designs. |
| ESD Rating | 1.5 kV CDM - provides robustness against handling-induced discharge during PCB assembly and field service. |
Pinout & Package
TL062CPSR is supplied in an 8-pin SOIC (PS) package measuring 6.20 mm × 7.80 mm, with standard dual-op-amp pinout compatible with industry layout practices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads ≥10 kΩ; short-circuit protected to either rail or ground. |
| 2 | IN– A | Inverting input A - high-impedance JFET node; sensitive to PCB leakage and EMI coupling. |
| 3 | IN+ A | Non-inverting input A - referenced to same high-Z node; used for unity-gain buffers and precision references. |
| 4 | VCC– | Negative supply rail - must be decoupled locally with ≥0.1 µF ceramic capacitor to suppress PSRR degradation. |
| 5 | IN+ B | Non-inverting input B - electrically isolated from Channel A; crosstalk attenuation >120 dB prevents inter-channel interference. |
| 6 | IN– B | Inverting input B - shares same JFET process as Channel A; matched offset and bias characteristics enable dual-channel instrumentation. |
| 7 | OUT B | Amplifier B output - independent drive capability; no shared internal nodes with Channel A. |
| 8 | VCC+ | Positive supply rail - accepts up to ±15 V; common-mode range extends to this rail, enabling rail-sensing applications. |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | Delivers 1012 Ω input resistance and sub-100 pA input bias current - essential for photodiode transimpedance and electrochemical sensor interfaces. |
| Internal frequency compensation | Guarantees stability in unity-gain follower and inverting configurations without external compensation networks. |
| Output short-circuit protection | Allows indefinite shorting to either supply or ground without damage - improves reliability in test fixtures and fault-prone industrial I/O. |
| Wide common-mode range (includes VCC+) | Enables direct connection to high-side current-sense resistors and rail-referenced thermistor dividers without level-shifting circuitry. |
| Latch-up-free process | Prevents destructive parasitic conduction during overvoltage or ESD events - critical for automotive and industrial 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 (2.5 mA per amp), 13 V/µs slew rate, lower input noise (18 nV/√Hz) | Better suited for wideband audio and fast transient response; less suitable for battery life-critical designs | Select TL072CDR when bandwidth and speed outweigh power constraints; not drop-in due to 12× higher ICC. |
| TL082CDR | Higher supply current (1.4 mA per amp), 13 V/µs slew rate, higher input bias current (300 pA typ.) | Offers improved AC performance but trades off input impedance and power efficiency | Choose TL082CDR for legacy designs requiring proven reliability in high-speed analog; verify input bias impact on high-Z sources. |
Compared with TL062CPSR, TL072CDR delivers superior speed and noise performance at significantly higher power cost, while TL082CDR offers a middle-ground trade-off between speed and input impedance - making TL062CPSR the optimal choice for low-quiescent, high-Z, thermally constrained applications.

FAQ
What is the maximum supply voltage for TL062CPSR?
The absolute maximum supply voltage for TL062CPSR is ±18 V (36 V total). However, the recommended operating range is ±5 V to ±15 V. Operation beyond ±15 V risks exceeding thermal limits and degrading long-term reliability, especially in the PS package with its 95 °C/W junction-to-ambient thermal resistance.
Does TL062CPSR support single-supply operation?
Yes, TL062CPSR supports single-supply operation because its common-mode input voltage range includes VCC+, allowing the non-inverting input to be biased near the positive rail. For proper linear operation, the output swing must remain within ±10 V of mid-supply when loaded with ≥10 kΩ, and input signals must stay within the specified VICR limits.
What is the input offset voltage specification for TL062CPSR?
TL062CPSR has a maximum input offset voltage of 15 mV at 25°C and 20 mV across the full 0°C to 70°C operating range. This parameter is production-tested per the TL06xC grade, and its temperature coefficient is limited to 10 µV/°C - ensuring predictable drift in temperature-varying environments.
How does TL062CPSR compare to TL072 in terms of power consumption?
TL062CPSR consumes only 200 µA per amplifier, whereas TL072 draws approximately 2.5 mA per amplifier - a 12.5× reduction. This makes TL062CPSR suitable for always-on, battery-powered applications where TL072 would drain energy too rapidly, despite TL072's higher slew rate and lower noise.
Is TL062CPSR pin-compatible with other dual op-amps in SOIC-8 packages?
TL062CPSR 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, electrical differences (e.g., supply current, input bias) require verification in the target circuit before substitution.
