Texas Instruments TL082ACP

Overview

TL082ACP from Texas Instruments is a dual JFET-input operational amplifier designed for precision analog signal conditioning in industrial and audio systems. It delivers 20 V/μs slew rate, ±1 mV input offset voltage (typ), 5.25 MHz gain-bandwidth product, 105 dB common-mode rejection ratio, and operates from ±2.25 V to ±20 V supplies. It is used in pro audio mixers and battery test equipment where low noise and rail-to-rail input capability are critical.

For engineers reviewing the TL082ACP datasheet, TL082ACP pinout, TL082ACP application, or TL082ACP equivalent, key selection factors include its FET-input architecture for ultra-low bias current (1 pA typ), wide supply range, output short-circuit protection, and compatibility with single- or dual-supply configurations in sensor interface and active filter designs.

Technical Context

The TL082ACP implements a high-slew-rate JFET differential input stage followed by a Class AB output stage, enabling fast settling (0.48 μs to 0.01%) and stable unity-gain operation with up to 300 pF capacitive load. Its input common-mode range extends to VCC+, supporting single-supply applications without level-shifting circuitry.

It features integrated EMI/RF filters and 1.5 kV HBM ESD protection, making it suitable for electrically noisy environments such as motor drive feedback loops and UPS control circuits. The device maintains 115 dB open-loop gain across –40°C to +125°C, ensuring consistent DC accuracy in temperature-varying embedded systems.

Key Specifications

Pinout & Package

TL082ACP is housed in an 8-pin PDIP (Plastic Dual In-line Package) with 0.3-inch body width and through-hole mounting. This package provides robust thermal performance (RθJA = 85°C/W) and mechanical stability for prototyping and legacy PCB designs.

FAQ

What is the maximum operating temperature range for the TL082ACP?

The TL082ACP is rated for operation from –40°C to +85°C (Commercial grade, 'C' suffix). This range is confirmed in Section 5.3 of the official datasheet under Recommended Operating Conditions for TL08xC devices. It does not support the extended –55°C to +125°C range of the TL082M or TL082H variants. Always verify ambient and junction temperature limits using RθJA = 85°C/W and actual power dissipation in your layout.

Does the TL082ACP have rail-to-rail output capability?

No, the TL082ACP does not provide rail-to-rail output swing. At VS = 40 V (±20 V) and RL = 10 kΩ, its output swings within 115–210 mV of the positive rail and 105–215 mV of the negative rail. This headroom increases under heavier loads (e.g., 520 mV at RL = 2 kΩ). For true rail-to-rail output, consider modern alternatives like the OPA2314 or TLV2462-but note these lack the TL082ACP's JFET input and wide supply range.

Can the TL082ACP be used with a single 5-V supply?

Yes, the TL082ACP supports single-supply operation down to 4.5 V total supply (e.g., 0 V and +4.5 V). Its input common-mode range includes the positive rail, allowing direct connection of sensors referenced to VCC. However, output swing will be limited to ~0.2 V above GND and ~4.3 V below VCC. For optimal linearity, bias inputs near mid-supply using resistive dividers or reference ICs like the REF3025.

Is the TL082ACP pin-compatible with other TL082 variants like TL082CP or TL082CDR?

Yes-TL082ACP, TL082CP, and TL082CDR share identical 8-pin PDIP (ACP/CP) or SOIC (CDR) pinouts and core electrical specifications. Differences lie in packaging (PDIP vs SOIC), temperature grade (C vs I vs M), and minor parameter distributions (e.g., offset voltage min/max). No PCB redesign is needed when substituting within the same package type, though thermal and layout considerations differ between through-hole and surface-mount variants.

What is the typical input capacitance of the TL082ACP?

The TL082ACP exhibits 100 MΩ || 2 pF differential input impedance and 6 TΩ || 1 pF common-mode input impedance, per Section 5.7 of the datasheet. These values reflect its JFET input structure: extremely high DC resistance combined with minimal parasitic capacitance, enabling stable operation with high-frequency sources and minimizing phase shift in active filter topologies up to several hundred kHz.
