Texas Instruments TL082IP

Overview

TL082IP 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, and operates from ±2.25 V to ±20 V supplies. Its rail-to-rail common-mode input range extending to VCC+ enables use in high-side sensing and single-supply biasing circuits.

For engineers reviewing the TL082IP datasheet, TL082IP pinout, TL082IP application, or TL082IP equivalent, key selection criteria include input offset drift (±2 μV/°C), low 37 nV/√Hz input voltage noise at 1 kHz, output short-circuit protection, and compatibility with capacitive loads up to 300 pF in closed-loop configurations.

Technical Context

The TL082IP uses a JFET-input differential pair with high-impedance, low-bias-current front-end (±1 pA typ), enabling accurate amplification of high-impedance sensor signals without loading. Its internal compensation ensures stability with unity-gain bandwidth of 5.25 MHz and phase margin of 56° at G = +1 with 20 pF load.

It features EMI rejection ratio of 53 dB at 1 GHz and integrated RF filters, making it suitable for noisy industrial environments. The device supports wide supply ranges (±2.25 V to ±20 V) and maintains CMRR ≥95 dB across –40°C to +125°C, critical for temperature-stable instrumentation.

Key Specifications

Pinout & Package

TL082IP is housed in an 8-pin PDIP (Plastic Dual In-line Package) with 0.3-inch body width and standard through-hole mounting. This package provides robust thermal performance (RθJA = 85°C/W) and mechanical reliability for industrial PCBs.

FAQ

What is the maximum capacitive load the TL082IP can drive stably?

The TL082IP is characterized for stable operation with capacitive loads up to 300 pF in unity-gain configuration, as confirmed in its Electrical Characteristics table. Driving heavier loads may require external isolation resistors or gain adjustment to maintain phase margin above 56°, especially in high-frequency applications like active filters or fast-settling buffers.

Does the TL082IP support single-supply operation?

Yes, the TL082IP supports single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing inputs to swing up to the positive rail-ideal for interfacing with rail-referenced sensors or level-shifting circuits without negative supply rails.

What is the input offset voltage specification for TL082IP at full temperature range?

For TL082IP (a member of the TL08xI grade), the input offset voltage is specified as ±3 mV (min) to ±6 mV (max) over the full operating temperature range of –40°C to +85°C. This is distinct from the TL082H variant, which guarantees ±1 mV at 25°C and ±5 mV over –40°C to +125°C.

How does the TL082IP handle overload or phase reversal conditions?

The TL082IP includes internal circuitry that prevents phase reversal during common-mode overvoltage events and provides output short-circuit protection. Its overload recovery time is 300 ns, and Figure 5-26–5-28 in the datasheet confirm no phase reversal under positive/negative overload conditions at G = –10.

Is the TL082IP pin-compatible with other TL082 variants like TL082CP or TL082CDR?

Yes, TL082IP shares identical pinout and electrical functionality with all TL082x variants in PDIP (P), SOIC (D), and SO (PS) packages. Pin compatibility is maintained across speed, offset, and temperature grades-including TL082CP (commercial), TL082CDR (SOIC), and TL082IP (industrial)-as verified in Table 4-3 and the Logic Symbols section.
