STMicroelectronics TL062IN

Overview

TL062IN from STMicroelectronics is a low-power JFET-input dual operational amplifier in an 8-pin DIP package, delivering 3.5 V/µs slew rate, ±11.5 V input common-mode range (up to V_CC+), and 200 µA supply current per amplifier at ±15 V. It features high input impedance (10¹² Ω), output short-circuit protection, and latch-up free operation-used in precision signal conditioning for industrial sensor interfaces and analog front-ends.

For engineers reviewing the TL062IN datasheet, TL062IN pinout, TL062IN application, or TL062IN equivalent, key selection criteria include its JFET-input bias current (≤200 pA), dual-channel isolation (120 dB), wide supply range (±3 V to ±18 V), and temperature-stable offset voltage (3–9 mV over –40°C to +105°C).

Technical Context

The TL062IN integrates matched high-voltage JFET and bipolar transistors on a monolithic die, enabling rail-to-rail input capability (±11.5 V with ±15 V supplies) and high CMRR (80–86 dB). Its internal frequency compensation ensures unity-gain stability without external components.

Designed for low-noise, low-power analog signal processing, it supports dual independent amplifiers sharing only the supply rails-no cross-talk beyond specified 120 dB channel separation-and operates across –40°C to +105°C with guaranteed performance in V_IO, I_IB, and slew rate.

FAQ

What is the maximum operating temperature range for TL062IN?

TL062IN is rated for operation from –40°C to +105°C, as confirmed in Table 2 of ST's Doc ID 2294 Rev 4. This industrial-grade temperature range is validated across all key parameters including input offset voltage (3–9 mV), supply current (200–250 µA), and output swing (≥20 V_PP), making it suitable for deployment in motor control cabinets and outdoor instrumentation enclosures.

Does TL062IN support single-supply operation?

Yes-TL062IN operates with split supplies (±3 V to ±18 V) or single-ended supplies (6 V to 36 V total), per Table 2. When used with single supply, the input common-mode range extends to within 1.5 V of V_CC– and V_CC+, enabling ground-referenced signal handling without level-shifting circuitry in many cases.

How does TL062IN's input bias current compare to bipolar-input op-amps?

TL062IN's JFET input delivers ≤200 pA typical input bias current-over 1,000× lower than bipolar-input equivalents like LM358 (45 nA). This reduces voltage errors across high-value feedback resistors (>1 MΩ) and enables accurate integration in leaky capacitive sensor interfaces where bias-induced drift would otherwise dominate.

Is TL062IN pin-compatible with other dual op-amps in DIP8 packages?

TL062IN follows the industry-standard dual op-amp pinout (Pin 1 = Out A, Pin 2 = In– A, Pin 3 = In+ A, Pin 4 = V–, Pin 5 = In+ B, Pin 6 = In– B, Pin 7 = Out B, Pin 8 = V+), matching LM358, TL072, and NE5532. However, electrical differences-including JFET vs. bipolar input, supply current, and slew rate-require verification of loop stability and noise performance in replacement designs.
