Texas Instruments TL062ACD

Overview

TL062ACD from STMicroelectronics is a low-power JFET-input dual operational amplifier in SO-8 package, delivering 3.5 V/µs slew rate, ±15 V supply range, and 200 µA quiescent current per amplifier. It operates across 0 °C to +70 °C, features high input impedance (10¹² Ω), 80 dB CMRR, and output short-circuit protection - used in precision signal conditioning for industrial sensor interfaces and audio preamplifier stages.

For engineers reviewing the TL062ACD datasheet, TL062ACD pinout, TL062ACD application, or TL062ACD equivalent, key selection criteria include JFET-input bias current (≤200 pA typ), input offset voltage (3–7.5 mV), channel separation (120 dB), and SO-8 thermal resistance (125 °C/W junction-to-ambient) in low-noise analog front-ends.

Technical Context

The TL062ACD integrates matched high-voltage JFET and bipolar transistors on a monolithic die, enabling rail-to-rail common-mode input range (±11.5 V with ±15 V supplies) and latch-up-free operation. Its internal frequency compensation ensures unity-gain stability without external components.

It delivers 1 MHz gain-bandwidth product at ±15 V, supports dual-channel independent operation with 120 dB channel separation, and maintains low input offset drift (10 µV/°C) - critical for DC-coupled instrumentation amplifiers and multi-stage active filters.

Key Specifications

Pinout & Package

TL062ACD is housed in an SO-8 (small outline integrated circuit) plastic micropackage, 4.8–5.0 mm wide × 5.8–6.2 mm long × 1.25–1.75 mm height, with gull-wing leads and 1.27 mm pitch.

FAQ

What is the maximum operating temperature range for TL062ACD?

The TL062ACD is rated for 0 °C to +70 °C free-air operating temperature, as confirmed in Table 2 of ST's Doc ID 2294 Rev 4. This commercial-grade specification aligns with its SO-8 packaging and intended use in non-automotive, non-military environments such as test equipment and consumer audio.

Does TL062ACD support single-supply operation?

Yes - though optimized for dual ±6 V to ±18 V supplies, TL062ACD can operate from a single 12 V to 36 V rail by biasing inputs and outputs within its common-mode range (e.g., using VCC/2 reference). Its input common-mode range extends to VCC− and up to VCC+, enabling true single-supply configurations with proper level-shifting.

Is TL062ACD pin-compatible with TL062CD?

Yes - both TL062ACD and TL062CD share identical SO-8 package dimensions, pinout, and footprint. The "A" suffix denotes tighter input offset voltage (3–7.5 mV vs. 3–20 mV for TL062CD), but electrical and mechanical compatibility is maintained per ST's ordering table (Table 7, Doc ID 2294 Rev 4).

What is the thermal resistance (R_thJA) of TL062ACD in SO-8 package?

TL062ACD in SO-8 has a typical junction-to-ambient thermal resistance of 125 °C/W, as specified in Table 1 of ST's datasheet (Doc ID 2294 Rev 4). This value assumes standard JEDEC 2-layer board layout; actual performance improves with copper pour and thermal vias under the exposed pad (if present) - though SO-8 variant lacks thermal pad.
