Texas Instruments TL062CDRE4

Overview

TL062CDRE4 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 TL062CDRE4 datasheet, TL062CDRE4 pinout, TL062CDRE4 application, or TL062CDRE4 equivalent, this page provides verified electrical specifications, SOIC-8 package layout, dual-channel functional context, thermal derating guidance, and validated alternative options for design continuity and sourcing resilience.

Technical Context

The TL062CDRE4 implements a JFET-input differential pair with internal frequency compensation, delivering rail-to-rail common-mode input capability (V_CM = V_CC– + 4 V to V_CC+ – 4 V) and output short-circuit protection. Its high input impedance (>10¹² Ω) and low input bias current (30 pA typ. at 25°C) minimize loading on high-impedance sources like piezoelectric sensors or photodiode transimpedance nodes.

Designed for single-supply or split-supply operation (±5 V to ±15 V), it supports stable unity-gain configurations without external compensation and exhibits 120 dB crosstalk attenuation between channels - critical for dual-channel instrumentation where inter-channel coupling must be minimized.

FAQ

What is the maximum supply voltage for TL062CDRE4?

The absolute maximum supply voltage for TL062CDRE4 is ±18 V (36 V total). However, the recommended operating range is ±5 V to ±15 V. Operation at ±18 V risks exceeding thermal limits and reducing long-term reliability; sustained use above ±15 V is not advised unless transient conditions are strictly controlled and junction temperature remains below 150°C.

Does TL062CDRE4 require external compensation capacitors?

No, TL062CDRE4 features internal frequency compensation and is stable in unity-gain configurations without external components. This simplifies layout and reduces bill-of-materials cost. External compensation is unnecessary for standard inverting, non-inverting, or voltage-follower circuits - though careful PCB routing and local decoupling remain essential for noise immunity.

Can TL062CDRE4 operate from a single 5-V supply?

Yes, TL062CDRE4 supports single-supply operation down to 5 V total (e.g., 0 V and +5 V). In this configuration, the common-mode input range extends from 4 V below V_CC+ (i.e., +1 V) to V_CC+ – 4 V (+1 V), and output swing is typically ±10 V with ±15 V supplies - so expect ~1 V to ~4 V output range with 5 V supply. Input biasing and level-shifting may be needed for full-rail signal handling.

What is the input offset voltage drift over temperature for TL062CDRE4?

The temperature coefficient of input offset voltage (αV_IO) for TL062CDRE4 is 10 µV/°C maximum across the full operating range (0°C to 70°C). This means offset can drift up to ±0.7 mV over a 70°C ambient change - a critical factor in precision DC amplification. For applications requiring tighter drift control, consider TL062BC variants or external nulling circuitry using pins 1 and 5 (not available on SOIC-8).

Is TL062CDRE4 pin-compatible with other dual op amps in SOIC-8 packages?

TL062CDRE4 shares the industry-standard SOIC-8 pinout with TL072, TL082, and RC4558 - all follow the same 1=OUT A, 2=IN– A, 3=IN+ A, 4=V_CC–, 5=IN+ B, 6=IN– B, 7=OUT B, 8=V_CC+ assignment. However, electrical differences (bias current, noise, slew rate) mean direct substitution requires validation of signal chain performance - especially in high-impedance or wideband applications.
