Texas Instruments TL062IPWR

Overview

TL062IPWR 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 V_CC+, enabling use in rail-to-rail-sensing front-ends for industrial sensor interfaces.

For engineers reviewing the TL062IPWR datasheet, TL062IPWR pinout, TL062IPWR application, or TL062IPWR equivalent, key selection considerations include its JFET-input bias current (≤200 pA at 25°C), unity-gain bandwidth (1 MHz), output short-circuit protection, and SOIC-8 packaging compatible with automated PCB assembly.

Technical Context

The TL062IPWR 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 currents while maintaining 10¹² Ω input resistance and 80 dB minimum CMRR across –40°C to 85°C.

Designed as a lower-power counterpart to the TL072 and TL082 families, the TL062IPWR supports split-supply operation from ±5 V to ±15 V, features latch-up-free silicon, and integrates EMI/RF filtering to sustain performance in electrically noisy environments such as motor control feedback loops and audio preamplifier stages.

FAQ

What is the maximum supply voltage rating for TL062IPWR?

The TL062IPWR has an absolute maximum supply voltage rating of ±18 V across V_CC+ and V_CC–. However, the recommended operating range is ±5 V to ±15 V. Operating beyond ±15 V risks exceeding thermal limits and degrading long-term reliability, even if within absolute ratings. Always refer to the thermal derating curves in the datasheet when designing for high ambient temperatures.

Does TL062IPWR support single-supply operation?

Yes, TL062IPWR supports single-supply operation with appropriate biasing. Its common-mode input range extends to V_CC+, allowing the non-inverting input to be biased at mid-supply (e.g., V_CC/2) using resistive dividers. The output swing is limited to approximately V_CC – 2 V and 2 V above ground under load, so proper headroom must be maintained for intended signal amplitude.

How does TL062IPWR compare to TL072 in terms of input bias current?

TL062IPWR specifies a typical input bias current of 30 pA at 25°C, significantly lower than TL072's typical 65 pA. This difference becomes critical in high-impedance applications like photodiode transimpedance amplifiers or pH probe buffers, where TL062IPWR reduces input offset error and improves long-term stability-especially at elevated temperatures where FET leakage increases exponentially.

Is TL062IPWR pin-compatible with other dual op-amps in SOIC-8 packages?

TL062IPWR uses the industry-standard dual op-amp pinout (pin 1 = OUT A, pin 2 = IN– A, pin 3 = IN+ A, pin 4 = V_CC–, pin 5 = IN+ B, pin 6 = IN– B, pin 7 = V_CC+, pin 8 = OUT B), matching TL072, TL082, and LM358 variants. However, electrical differences-including supply current, input offset, and bandwidth-require circuit validation before substitution, even with identical pinouts.

What is the typical input voltage noise density of TL062IPWR at 1 kHz?

The TL062IPWR exhibits a typical input voltage noise density of 30 nV/√Hz at 1 kHz, as confirmed in Section 6.10 of the official datasheet. This value is lower than earlier TL06x revisions (which specified 42 nV/√Hz) and reflects process improvements. At lower frequencies (<100 Hz), 1/f noise dominates; at higher frequencies (>10 kHz), thermal noise becomes dominant-both consistent with JFET-input architecture behavior.
