Texas Instruments TL062ACDE4

Overview

TL062ACDE4 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 V_CC+), 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 TL062ACDE4 datasheet, TL062ACDE4 pinout, TL062ACDE4 application, or TL062ACDE4 equivalent, key selection criteria include its JFET-input stage (10¹² Ω input resistance), low input bias current (30 pA typ at 25°C), rail-to-rail-compatible common-mode range, and SOIC-8 packaging - all critical for low-drift, low-noise, single-supply or split-supply op-amp circuits requiring stable DC performance over temperature.

Technical Context

The TL062ACDE4 implements a two-stage JFET-input transconductance amplifier architecture with internal frequency compensation, delivering stable unity-gain operation without external compensation. Its input stage uses matched JFET pairs to achieve ultra-low input bias and offset currents, while the output stage provides short-circuit protection and ±10 V output swing into 10 kΩ at ±15 V supplies.

Designed as a low-power counterpart to the TL072 and TL082 families, the TL062ACDE4 maintains comparable AC performance (1 MHz GBW, 3.5 V/µs slew rate) while reducing quiescent current by ~50%. It supports operation from ±5 V to ±15 V supplies and features integrated EMI/RF filters and 1.5 kV HBM ESD protection - making it suitable for noisy industrial environments and portable electronics where power efficiency and robustness are co-prioritized.

FAQ

What is the maximum supply voltage for TL062ACDE4?

The absolute maximum supply voltage for TL062ACDE4 is ±18 V, but the 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 SOIC-8 package where R_θJA is 97°C/W. For designs using ±15 V supplies, ensure adequate board-level heat sinking if ambient temperatures exceed 50°C.

Does TL062ACDE4 support single-supply operation?

Yes, TL062ACDE4 supports single-supply operation with appropriate input biasing. Its common-mode input range extends to V_CC+, allowing the non-inverting input to be biased at mid-supply (e.g., 2.5 V on a 5 V rail) while maintaining full output swing. However, output swing is limited to approximately 1.5 V from each rail under load, so design margins must account for headroom in rail-to-rail signal chains.

How does the input offset voltage of TL062ACDE4 compare to TL072?

TL062ACDE4 has a typical input offset voltage of 3 mV (max 15 mV), whereas TL072CDR specifies 3 mV typical (max 10 mV). While both fall within similar ranges, TL062ACDE4's offset drift is 10 µV/°C - identical to TL072 - ensuring comparable thermal stability. The key distinction lies in bias current: TL062ACDE4's 30 pA is one order of magnitude lower than TL072's 300 pA, making it superior for high-Z sources.

Is TL062ACDE4 pin-compatible with other dual op-amps in SOIC-8?

TL062ACDE4 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 = OUT B, pin 8 = V_CC+), matching TL072, TL082, and LM358 families. However, due to differing input stage architectures (JFET vs bipolar), direct substitution may require verification of input bias current impact, common-mode range, and supply current in the target circuit.

What is the thermal resistance (R_θJA) of TL062ACDE4 in SOIC-8 package?

The junction-to-ambient thermal resistance (R_θJA) for TL062ACDE4 in the D (SOIC-8) package is 97°C/W, as specified in TI's datasheet Section 6.5. This value assumes standard JEDEC 2-layer test board conditions. In real-world layouts with copper pour and thermal vias, actual R_θJA can improve to ~60–75°C/W, enabling higher continuous power dissipation - critical when operating two amplifiers near their 7.5 mW per amplifier limit.
