Texas Instruments TL082CPSR

Overview

TL082CPSR from Texas Instruments is a dual JFET-input operational amplifier designed for precision analog signal conditioning in industrial and audio systems. It delivers 5.25 MHz gain-bandwidth, 20 V/μs slew rate, ±15 V supply operation, low 37 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail common-mode input range extending to VCC+. It is used in pro audio mixers and battery test equipment where low distortion (0.003% THD+N) and high CMRR (100 dB) are critical.

For engineers reviewing the TL082CPSR datasheet, TL082CPSR pinout, TL082CPSR application, or TL082CPSR equivalent, this page provides verified specifications, SO-8 package terminal mapping, real-world use cases in motor drive feedback and UPS monitoring, and validated alternative options with documented functional and thermal differences.

Technical Context

The TL082CPSR implements a dual-channel JFET-input architecture with high-impedance inputs (1 TΩ common-mode resistance), internal EMI filtering, and output short-circuit protection. Its input stage supports common-mode voltages up to VCC+, enabling single-supply configurations without level-shifting circuitry.

It operates across 0°C to 70°C ambient temperature with ±2.25 V to ±20 V dual-supply or 4.5 V to 40 V single-supply capability. The device exhibits 115–125 dB open-loop gain and 56° phase margin into 10 kΩ//20 pF loads, ensuring stable unity-gain operation without external compensation.

Key Specifications

Pinout & Package

TL082CPSR is supplied in an 8-pin SOIC (PS) package with standard JEDEC MS-012AC footprint (5.3 mm × 6.2 mm, 1.27 mm pitch). Thermal resistance RθJA = 95°C/W enables operation at up to 70°C ambient with moderate power dissipation.

FAQ

What is the maximum operating temperature range for TL082CPSR?

The TL082CPSR is specified for operation from 0°C to +70°C ambient temperature. This commercial-grade rating aligns with its TL08xC suffix designation and is validated per TI's SLOS081O datasheet Section 5.3. Operation beyond this range may result in degraded offset drift, reduced CMRR, or increased quiescent current - TL082CPSR must not be substituted for automotive or extended-temperature variants like TL082I or TL082M without requalification.

Does TL082CPSR support single-supply operation?

Yes, TL082CPSR supports true single-supply operation from 4.5 V to 40 V. Its common-mode input range extends from VCC– to VCC+, allowing inputs to swing up to the positive rail - a key enabler for single-supply sensor interfaces. However, output swing remains limited to ~1.2 V from each rail under 2 kΩ load, so mid-rail biasing (e.g., VCC/2 reference) is required for AC-coupled signals.

What is the input bias current specification for TL082CPSR?

TL082CPSR exhibits input bias current of 65–200 pA typical at 25°C, with a maximum of 7 nA over full temperature range (0°C to 70°C). This ultra-low value stems from its JFET input stage and enables high-impedance applications such as photodiode transimpedance amplifiers or high-value resistor networks where leakage would otherwise dominate error budgets.

Can TL082CPSR drive capacitive loads directly?

TL082CPSR is characterized to drive up to 300 pF capacitive load while maintaining stability (56° phase margin), per Section 5.7 of the datasheet. For loads exceeding 300 pF - such as long cables or ADC input capacitance - external isolation resistance (e.g., 100 Ω in series with output) is required to prevent peaking or oscillation. TL082CPSR does not include internal compensation for heavy capacitive loading.

How does TL082CPSR differ from TL082H in practical design?

TL082CPSR (C-grade) specifies 3–10 mV input offset and 0°C–70°C operation, while TL082H (H-grade) achieves 1 mV typical offset and –40°C–125°C operation. TL082CPSR uses older process technology with higher noise (37 nV/√Hz vs. 37 nV/√Hz same, but H-grade adds EMI filtering), making it suitable for cost-driven commercial designs where extreme precision or extended temperature is unnecessary - TL082CPSR remains fully pin-compatible and functionally interchangeable in non-military/industrial contexts.
