Texas Instruments TL062CDRG4

Overview

TL062CDRG4 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 TL062CDRG4 datasheet, TL062CDRG4 pinout, TL062CDRG4 application, or TL062CDRG4 equivalent, this page provides verified electrical parameters, SOIC-8 package mapping, dual-amplifier functional context, thermal derating guidance, and real-world substitution options aligned with TI's SLOS078N revision August 2023 production data.

Technical Context

The TL062CDRG4 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 ultra-low input bias current (30 pA typ. at 25°C) minimize loading on high-impedance sources like piezoelectric sensors or photodiode transimpedance nodes.

Designed as a lower-power counterpart to the TL072 and TL082 families, it maintains comparable AC performance (1 MHz GBW, 3.5 V/µs slew rate) while reducing quiescent current by ~50%. It operates across 0°C to 70°C (Commercial grade) with ±5 V to ±15 V dual-supply support and integrated EMI/RF filtering for noise-resilient operation in mixed-signal environments.

FAQ

What is the maximum operating supply voltage for TL062CDRG4?

The absolute maximum supply voltage for TL062CDRG4 is ±18 V (36 V total). However, the recommended operating range is ±5 V to ±15 V per the datasheet. Operating beyond ±15 V risks exceeding junction temperature limits and may degrade long-term reliability - especially in SOIC-8 packages with R_θJA = 97°C/W. Always verify thermal margin using P_D = (T_J(max) – T_A) / R_θJA for your layout and ambient conditions.

Does TL062CDRG4 support single-supply operation?

TL062CDRG4 is specified for dual-supply operation (±V_CC), but can be used in single-supply configurations with proper biasing. Its common-mode input range extends to V_CC– + 4 V, so with V_CC– = 0 V and V_CC+ = +15 V, inputs can swing from +4 V to +11 V. Output swing is limited to ±10 V under load - meaning a mid-rail reference (e.g., +7.5 V) and AC-coupled inputs are typically required for full-range signal handling in single-supply TL062CDRG4 designs.

What is the input offset voltage specification for TL062CDRG4 at full temperature range?

For TL062CDRG4 (Commercial grade, 0°C to 70°C), the input offset voltage is guaranteed to be ≤20 mV across the full temperature range. At 25°C, it is tighter: ≤3 mV typical and ≤15 mV maximum. The temperature coefficient is ≤10 µV/°C, meaning worst-case drift adds ≤700 µV over the 70°C span - critical for DC-critical applications like precision current sensing or integrator circuits where long-term drift dominates error budgets.

How does TL062CDRG4 compare to TL062CP in terms of performance and packaging?

TL062CDRG4 and TL062CP share identical electrical specifications and temperature grading (Commercial, 0°C to 70°C), but differ in packaging and compliance. TL062CDRG4 is a green, RoHS-compliant, lead-free SOIC-8 device with tape-and-reel packaging (G4 suffix); TL062CP is a legacy PDIP-8 package with leaded finish. Both meet the same SLOS078N spec sheet, but TL062CDRG4 supports modern SMT assembly and environmental requirements, while TL062CP suits through-hole prototyping or legacy repair.

Is TL062CDRG4 suitable for driving capacitive loads?

TL062CDRG4 is not unity-gain stable into purely capacitive loads >100 pF without isolation resistance. Driving cables or ADC input capacitance directly may cause peaking or oscillation. For loads >100 pF, add a 100 Ω to 500 Ω series resistor between TL062CDRG4 output and the capacitance - this isolates the pole and restores phase margin. This technique is validated in TI's SLOS078N Figure 7-1 and maintains stability while preserving bandwidth for most sensor interface use cases.
