Product details
Overview
TL062CPW 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 slew rate, and ±11 V common-mode input range extending to VCC+, enabling use in rail-to-rail-sensing front-ends for industrial sensor interfaces and battery-powered instrumentation.
For engineers reviewing the TL062CPW datasheet, TL062CPW pinout, TL062CPW application, or TL062CPW equivalent, key selection criteria include its JFET-input bias current (≤200 pA at 25°C), unity-gain bandwidth (1 MHz), output short-circuit protection, and TSSOP-8 package compatibility with space-constrained PCB layouts.
Technical Context
The TL062CPW implements a two-stage JFET-input transconductance amplifier architecture with internal frequency compensation, delivering stable unity-gain operation without external components. Its high-impedance differential pair enables ultra-low input bias current while maintaining 80 dB CMRR and 80 dB PSRR across –40°C to 85°C.
Designed as a low-power counterpart to the TL072 and TL082 families, the TL062CPW trades 10–15% bandwidth and slew rate for >50% reduction in quiescent current - making it suitable for always-on monitoring stages where thermal budget and battery life are critical constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables dual op-amp operation from microamp-level power rails in portable or energy-harvesting systems |
| Slew Rate | 3.5 V/µs typical - supports audio-band signal amplification and moderate-speed sensor signal conditioning without distortion |
| Input Bias Current | ≤200 pA at 25°C - preserves signal integrity in high-impedance source applications like piezoelectric sensors or pH electrodes |
| Common-Mode Range | Extends to VCC+ - allows direct interface with single-supply sensors operating near positive rail |
| Unity-Gain Bandwidth | 1 MHz - sufficient for anti-aliasing filters, active RC networks, and DC-coupled gain stages up to ~10× closed-loop gain |
| Input Resistance | 1012 Ω - minimizes loading error on high-Z sources such as photodiode transimpedance feedback networks |
| ESD Rating | 1.5 kV HBM - provides robustness against handling-induced discharge during assembly of consumer and industrial PCBs |
Pinout & Package
TSSOP-8 (PW) package: 3.00 mm × 6.40 mm body, 0.65 mm lead pitch, exposed pad not electrically connected, RoHS-compliant matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads ≥10 kΩ; short-circuit protected to ground or either supply rail |
| 2 | IN− A | Inverting input A - high-impedance JFET node; requires guarding in sensitive low-noise layouts |
| 3 | IN+ A | Non-inverting input A - accepts common-mode voltage up to VCC+; matched to IN− A for offset optimization |
| 4 | VCC− | Negative supply - referenced to system ground in single-supply configurations; must be decoupled locally |
| 5 | IN+ B | Non-inverting input B - independent channel; no crosstalk coupling to Channel A (120 dB attenuation) |
| 6 | IN− B | Inverting input B - symmetrical to IN− A; supports dual-channel instrumentation or differential receiver topologies |
| 7 | OUT B | Amplifier B output - electrically isolated from OUT A; shares same thermal and supply characteristics |
| 8 | VCC+ | Positive supply - supplies both amplifiers; requires 0.1 µF ceramic + 10 µF tantalum decoupling per supply pin |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input op-amp applications.

|---|---|---|---|
| TL072CPW | Higher supply current (2.5 mA vs 200 µA), 13 V/µs slew rate, lower input noise (18 nV/√Hz) | Better suited for high-fidelity audio or wideband signal paths where power is not constrained | Choose TL072CPW when bandwidth and noise performance outweigh power savings requirements |

Compared with TL072CPW and TL082CPW, the TL062CPW offers the lowest power envelope among TI's industry-standard dual JFET op-amps - making it the optimal choice for always-on sensing, battery-backed monitoring, and thermally limited embedded systems where 200 µA per amplifier directly translates to extended operational lifetime or reduced heatsinking needs.

FAQ
What is the maximum supply voltage rating for TL062CPW?
The TL062CPW has an absolute maximum supply voltage rating of ±18 V (36 V total). However, its recommended operating range is ±5 V to ±15 V. Operating beyond ±15 V risks exceeding thermal limits and degrading long-term reliability, especially in the TSSOP-8 package where RθJA = 149°C/W limits power dissipation to ~7.5 mW per amplifier at room temperature.
Does TL062CPW support single-supply operation?
Yes, TL062CPW supports true single-supply operation. Its common-mode input voltage range extends to VCC+, allowing the non-inverting input to accept signals up to the positive rail. For proper output swing, the negative supply (Pin 4) must be tied to ground or a reference voltage, and the output will swing within ±10 V of the mid-supply point when loaded with ≥10 kΩ.
How does TL062CPW differ from TL072CPW in practical design?
TL062CPW consumes 10× less supply current than TL072CPW (200 µA vs 2.5 mA per amplifier), making it ideal for battery-powered or thermally constrained systems. In exchange, it offers lower slew rate (3.5 V/µs vs 13 V/µs) and higher input noise (30 nV/√Hz vs 18 nV/√Hz), which affects high-frequency fidelity but not DC or low-speed sensor applications.
Is TL062CPW pin-compatible with other dual op-amps in TSSOP-8?
TL062CPW 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 matches TL072CPW, TL082CPW, and LM358 variants - enabling drop-in replacement where power and noise specifications permit.
What layout practices improve noise performance of TL062CPW?
To minimize noise in TL062CPW circuits, use guard rings around IN+ and IN− traces, place 0.1 µF ceramic and 10 µF bulk capacitors within 5 mm of Pins 4 and 8, avoid routing digital traces beneath the device, and connect the TSSOP-8 thermal pad to a solid ground plane if thermal relief is not required. Input bias current errors are further reduced by matching trace impedances to both inputs.
