Texas Instruments TL062CPG4

Overview

TL062CPG4 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.

For engineers reviewing the TL062CPG4 datasheet, TL062CPG4 pinout, TL062CPG4 application, or TL062CPG4 equivalent, key selection criteria include its JFET-input stage (10¹² Ω input resistance), low input bias current (30 pA typ.), output short-circuit protection, and compatibility with ±5 V to ±15 V dual supplies across –40°C to +85°C ambient operation.

Technical Context

The TL062CPG4 implements a two-stage JFET-input op amp architecture with internal frequency compensation, delivering stable unity-gain operation without external components. Its input stage uses matched JFET pairs to achieve ultra-low input bias and offset currents, while the output stage provides rail-to-rail compatible swing (±10 V into 10 kΩ) and short-circuit protection.

Designed as a low-power counterpart to the TL072/TL082 families, the TL062CPG4 maintains comparable AC performance (1 MHz GBW, 3.5 V/µs SR) while reducing quiescent current by ~50%. It supports single-supply operation via input common-mode range extending to V_CC+, and includes integrated EMI/RF filters for robustness in noisy environments.

FAQ

What is the maximum supply voltage rating for TL062CPG4?

The TL062CPG4 has an absolute maximum supply voltage rating of ±18 V (36 V total). However, its recommended operating range is ±5 V to ±15 V. Operating beyond ±15 V may increase power dissipation and thermal stress without improving performance, and is not validated for long-term reliability. Always observe derating guidelines in the datasheet's thermal information section for the PDIP package.

Does TL062CPG4 support single-supply operation?

Yes, TL062CPG4 supports single-supply operation due to its common-mode input voltage range extending to V_CC+. When powered from a single +15 V rail with V_CC– tied to ground, the input can accept signals from 0 V up to +15 V. Output swing remains limited to approximately 0 V to +10 V under load, so level-shifting or rail-splitting may be needed for full-scale AC coupling.

What is the input offset voltage specification for TL062CPG4?

The TL062CPG4 has a maximum input offset voltage of 6 mV at 25°C and full temperature range (0°C to 70°C), with a typical value of 3 mV. Its temperature coefficient is 10 µV/°C, meaning offset drift contributes ≤0.7 mV over a 70°C span. This makes TL062CPG4 suitable for medium-accuracy DC amplification where trimming is impractical.

How does TL062CPG4 compare to TL062CDR in terms of package and performance?

TL062CPG4 (PDIP-8) and TL062CDR (SOIC-8) share identical electrical specifications, including supply current, slew rate, and input characteristics. The difference lies solely in packaging: PG4 denotes through-hole PDIP for prototyping and legacy systems; D indicates surface-mount SOIC for automated assembly and space-constrained layouts. Thermal resistance differs (R_θJA = 85°C/W for PG4 vs. 97°C/W for D), affecting power handling in high-density boards.

Is TL062CPG4 suitable for driving capacitive loads?

TL062CPG4 is not optimized for heavy capacitive loads. Its internal compensation targets resistive loads ≥2 kΩ. Driving >100 pF directly may cause peaking or oscillation. For capacitive loads, use a series isolation resistor (e.g., 100 Ω) between output and capacitance, or add a unity-gain buffer stage. Refer to Figure 7-1 in the datasheet for verified test conditions using 100 pF.
