STMicroelectronics TL062CDT

Overview

TL062CDT from STMicroelectronics is a low-power JFET-input dual operational amplifier in SO-8 package, delivering 3.5 V/µs slew rate, 1 MHz gain-bandwidth product, and 200 µA supply current per amplifier at ±15 V. It features high input impedance (10¹² Ω), rail-to-rail common-mode range (±11.5 V), and output short-circuit protection - used in precision signal conditioning for industrial sensor interfaces and audio preamplifier stages.

For engineers reviewing the TL062CDT datasheet, TL062CDT pinout, TL062CDT application, or TL062CDT equivalent, key selection considerations include its JFET-input bias current (≤200 pA typ), dual-channel isolation (120 dB channel separation), temperature-stable offset voltage (≤20 mV max over 0–70°C), and SO-8 footprint compatibility with legacy TL062 designs requiring low quiescent power.

Technical Context

The TL062CDT integrates matched high-voltage JFET and bipolar transistors on a monolithic die to achieve low input bias current and high slew rate simultaneously. Its internal frequency compensation ensures unity-gain stability without external components across load capacitances up to 100 pF.

It operates from ±3 V to ±18 V supply rails (6–36 V total), supports common-mode inputs up to the positive rail (VCC+), and maintains 4 V/mV large-signal voltage gain with 80 dB CMRR and 80 dB SVR - enabling robust performance in noisy industrial environments where ground-referenced sensing is required.

Key Specifications

FAQ

What is the maximum operating temperature range for TL062CDT?

TL062CDT is rated for 0 °C to +70 °C ambient operating temperature, as indicated by the "C" suffix in its part number. This commercial-grade rating is validated per Table 2 of ST's Doc ID 2294 Rev 4, with guaranteed electrical performance including input offset voltage ≤20 mV and supply current ≤250 µA across that full range.

Does TL062CDT support single-supply operation?

Yes - TL062CDT supports single-supply operation with common-mode input range extending to VCC+ (e.g., up to +36 V when VCC− = 0 V). However, its output swing does not reach the negative rail; minimum output is typically ~1.5 V above VCC−, so level-shifting or rail-splitting is needed for true ground-referenced output.

Is TL062CDT pin-compatible with other SO-8 dual op-amps?

TL062CDT uses standard SO-8 pinout (Pin 1 = Out1, Pin 2 = In−1, Pin 3 = In+1, Pin 4 = V−, Pin 5 = In+2, Pin 6 = In−2, Pin 7 = Out2, Pin 8 = V+), matching industry-standard dual op-amp footprints including LM358, TL072, and RC4558. Mechanical compatibility is confirmed by ST's SO-8 mechanical data (Table 6, Doc ID 2294 Rev 4).

What is the typical input offset voltage drift over temperature for TL062CDT?

TL062CDT exhibits a temperature coefficient of input offset voltage of 10 µV/°C (typical), as specified in Tables 3 and 4 of the datasheet. This means offset voltage changes by approximately ±0.5 mV across a 50°C ambient shift - critical for DC-coupled sensor amplifiers requiring long-term baseline stability.
