Product details
Overview
TL062CPWR 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 TL062CPWR datasheet, TL062CPWR pinout, TL062CPWR application, or TL062CPWR equivalent, this page provides verified electrical specifications, SOIC-8 package details, dual-amplifier functional context, thermal performance data, and validated alternative options for design-in and BOM optimization.
Technical Context
The TL062CPWR implements a JFET-input differential pair with internal frequency compensation, delivering rail-to-rail common-mode input capability (VCM = VCC– + 4 V to VCC+ – 4 V) and output short-circuit protection. Its high input impedance (>1012 Ω) and ultra-low input bias current (30 pA typ. 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 and TL082 families, the TL062CPWR 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) with ±5 V to ±15 V dual-supply support and integrated EMI/RF filtering for robustness in noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current (per amp) | 200 µA typical - enables multi-channel analog signal chains in power-constrained applications 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 accuracy in high-Z sensor interfaces and integrator circuits where leakage dominates error. |
| Common-Mode Input Range | VCC– + 4 V to VCC+ – 4 V - allows direct connection to signals referenced to positive rail, simplifying level-shifting in single-supply-derived dual-rail systems. |
| Unity-Gain Bandwidth | 1 MHz - sets usable small-signal bandwidth for gain ≥1 configurations; sufficient for anti-aliasing filters and active RC networks up to ~100 kHz. |
| Input Offset Voltage | 3 mV max at 25°C - defines baseline DC error in precision amplification; stable over temperature (10 µV/°C TC). |
| ESD Rating (HBM) | 2000 V - meets standard handling requirements for assembly in non-classified manufacturing environments. |
Pinout & Package
Packaged in an 8-pin SOIC (Small Outline Integrated Circuit) with 1.27 mm pitch, the TL062CPWR measures 4.90 mm × 6.00 mm and is rated for surface-mount reflow (JEDEC Level 3). The package supports automated placement and offers moderate thermal resistance (RθJA = 97°C/W).
| 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 of Amp A - high-impedance JFET node; sensitive to PCB leakage; requires guard ring in high-Z layouts. |
| 3 | IN+ A | Non-inverting input of Amp A - same high-Z characteristics as IN–; common-mode range extends to VCC+. |
| 4 | VCC– | Negative supply rail - must be decoupled locally with 0.1 µF ceramic capacitor to ground. |
| 5 | IN+ B | Non-inverting input of Amp B - electrically isolated from Amp A; crosstalk attenuation >120 dB at 100× gain. |
| 6 | IN– B | Inverting input of Amp B - independent bias path; no shared substrate coupling with Amp A inputs. |
| 7 | OUT B | Amplifier B output - fully independent output stage; supports separate feedback networks without interaction. |
| 8 | VCC+ | Positive supply rail - supplies both amplifiers; requires local 0.1 µF ceramic decoupling to minimize PSRR degradation. |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | Input impedance >1012 Ω enables direct interfacing with megohm-level sources (e.g., pH electrodes, capacitive sensors) without signal attenuation. |
| Low power consumption | 200 µA per amplifier allows integration of multiple channels in space- and power-limited modules (e.g., portable medical monitors, IoT sensor nodes). |
| Output short-circuit protection | Prevents device failure during accidental output shorts or capacitive load instability, eliminating need for external current-limiting resistors. |
| Internal frequency compensation | Guarantees unity-gain stability without external compensation components - reduces BOM count and layout complexity. |
| Wide common-mode voltage range | Supports input signals up to VCC+, enabling simplified single-ended-to-differential conversion and rail-referenced signal acquisition. |

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 |
|---|---|---|---|
| TL072CPWR | Higher supply current (1.4 mA/amp), faster slew rate (13 V/µs), tighter input offset (10 mV max), same SOIC-8 package. | Better suited for wideband audio or fast control loops where speed outweighs power budget. | Select TL072CPWR when system power budget permits higher quiescent draw and bandwidth >3 MHz is required. |
| RC4558PWR | Bipolar-input (not JFET), higher input bias (300 nA), lower input impedance (~300 kΩ), 10x higher supply current (1.3 mA/amp). | Cost-optimized general-purpose use; unsuitable for high-Z sensor interfaces or low-power designs. | Choose RC4558PWR only for non-critical, low-cost applications where input bias and power are not limiting factors. |
Compared with TL072CPWR, TL062CPWR trades bandwidth and speed for 86% lower supply current - critical for multi-channel, battery-operated systems. Compared with RC4558PWR, TL062CPWR provides 10,000× lower input bias and 30× lower power, making it essential for precision high-impedance signal paths.

FAQ
What is the maximum supply voltage for TL062CPWR?
The TL062CPWR supports dual-supply operation from ±5 V to ±15 V. Absolute maximum ratings specify ±18 V, but sustained operation above ±15 V risks reliability degradation and is outside recommended conditions. For designs using ±12 V rails, the TL062CPWR delivers full specified performance including ±10 V output swing and 1 MHz bandwidth.
Does TL062CPWR require external compensation components?
No, TL062CPWR features internal frequency compensation and is unity-gain stable without external capacitors or resistors. This eliminates layout sensitivity and component count in standard inverting, non-inverting, and voltage-follower configurations - confirmed across all operating temperatures and supply voltages per TI SLOS078N datasheet Section 6.10.
Can TL062CPWR drive capacitive loads directly?
TL062CPWR is not optimized for heavy capacitive loads. Driving >100 pF directly may cause peaking or oscillation due to phase margin reduction. For loads exceeding 100 pF (e.g., long cables or ADC input capacitance), add a 100 Ω isolation resistor in series with the output - a practice validated in TI Application Report SLOA058B for JFET-input op-amps.
What is the input offset voltage drift over temperature for TL062CPWR?
The TL062CPWR has a guaranteed maximum input offset voltage temperature coefficient of 10 µV/°C across its full operating range (0°C to 70°C). At 25°C, VIO is ≤3 mV; worst-case drift adds ≤0.7 mV over a 70°C span, supporting stable DC-coupled gain accuracy in uncalibrated industrial sensors.
Is TL062CPWR pin-compatible with TL072CPWR or TL082CPWR?
Yes, TL062CPWR shares identical SOIC-8 pinout and footprint with TL072CPWR and TL082CPWR. All three devices use 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), and Pin 8 (VCC+). This enables drop-in substitution where lower power consumption is acceptable and bandwidth requirements permit.
