Texas Instruments TL082CPSRG4

Overview

TL082CPSRG4 from Texas Instruments is a dual JFET-input operational amplifier optimized for precision AC/DC signal conditioning in industrial and audio systems. It delivers 5.25 MHz gain-bandwidth, 20 V/μs slew rate, ±13.5 V output swing (RL ≥ 10 kΩ), 70–100 dB CMRR, and 37 nV/√Hz input voltage noise at 1 kHz - enabling high-fidelity amplification in pro audio mixers and battery test equipment.

For engineers reviewing the TL082CPSRG4 datasheet, TL082CPSRG4 pinout, TL082CPSRG4 application, or TL082CPSRG4 equivalent, key selection criteria include its SOIC-8 package, dual-channel FET-input architecture, rail-to-rail common-mode input range (including VCC+), low 3 mV max input offset voltage, and compatibility with ±2.25 V to ±20 V dual supplies or 4.5 V to 40 V single supply.

Technical Context

The TL082CPSRG4 implements a high-slew-rate JFET differential input stage followed by a Class AB output stage with short-circuit protection. Its input stage supports common-mode voltages up to VCC+, enabling direct sensing of signals referenced to the positive rail - critical in motor drive current-sense and solar inverter DC-link monitoring.

It operates across 0°C to 70°C (commercial grade), draws 1.4–2.5 mA per amplifier, and maintains stable unity-gain performance with capacitive loads up to 300 pF. The device exhibits 0.003% THD+N at 1 kHz and features integrated EMI filtering for robust operation in electrically noisy environments like UPS power stages.

FAQ

What is the maximum operating temperature range for the TL082CPSRG4?

The TL082CPSRG4 is specified for commercial-grade operation from 0°C to 70°C ambient temperature. This range is defined in Section 5.3 (Recommended Operating Conditions) of the datasheet and applies to all TL08xC variants including TL082CPSRG4. Operation outside this range may result in degraded offset voltage drift, reduced CMRR, or increased input bias current beyond guaranteed limits.

Does the TL082CPSRG4 support single-supply operation?

Yes, the TL082CPSRG4 supports single-supply operation from 4.5 V to 40 V. Its input common-mode range extends to VCC+, allowing the non-inverting input to be biased at the positive rail - a key enabler for single-supply sensor interfaces. However, output swing remains limited to within ~1.5 V of each rail, so proper output biasing (e.g., mid-rail reference) is required for AC-coupled signals.

What is the input offset voltage specification for TL082CPSRG4?

The TL082CPSRG4 has a maximum input offset voltage of 10 mV at TA = 25°C, with a typical value of 3 mV. Over the full 0°C to 70°C temperature range, the maximum offset increases to 13 mV. This parameter is critical for DC-coupled applications such as precision current sensing, where offset directly contributes to measurement error.

Can TL082CPSRG4 drive capacitive loads?

Yes, the TL082CPSRG4 is characterized to safely drive capacitive loads up to 300 pF while maintaining stability. This capability is confirmed in the "Capacitive load drive" specification (300 pF) under Section 5.7. For loads exceeding 300 pF, external isolation resistors (e.g., 10–100 Ω in series with the output) are recommended to prevent peaking or oscillation in closed-loop configurations.

Is TL082CPSRG4 pin-compatible with other TL082 variants?

Yes, TL082CPSRG4 is pin-compatible with all TL082x devices in the SOIC-8 (PS) package, including TL082CDR, TL082CP, and TL082ACDR. Pin functions - 1OUT, 1IN−, 1IN+, VCC−, 2IN+, 2IN−, 2OUT, VCC+ - are identical across these variants. Differences lie only in temperature grade, packaging finish (e.g., green RoHS), and minor parametric shifts - not pinout or footprint.
