Texas Instruments TL082ACPS

Overview

TL082ACPS from Texas Instruments is a dual JFET-input operational amplifier designed for precision analog signal conditioning in dual-channel configurations. It delivers 13 V/μs slew rate, 3 MHz unity-gain bandwidth, ±13.5 V maximum output swing (RL ≥10 kΩ), 30 pA typical input bias current, and operates across 0°C to 70°C. It is used in audio preamplifiers, sensor signal conditioning, and active filter stages where low input current and wide common-mode range are critical.

For engineers reviewing the TL082ACPS datasheet, TL082ACPS pinout, TL082ACPS application, or TL082ACPS equivalent, key selection criteria include its JFET-input stage enabling high-impedance source interfacing, dual-amplifier topology for space-constrained designs, offset voltage adjust capability via external pins, and compatibility with ±5 V to ±15 V dual supplies.

Technical Context

The TL082ACPS integrates two matched JFET-input op-amps on a single die, using high-voltage JFETs for input stage and bipolar transistors for output stage. Its architecture supports rail-to-rail input common-mode range (VCC– +4 V to VCC+ –4 V) and provides internal frequency compensation for stable unity-gain operation.

It features dedicated offset null pins (OFFSET N1 and OFFSET N2) per amplifier, enabling precise DC offset correction without external trimming resistors. The device lacks shutdown or rail-to-rail output capability, and its output stage is not class-AB optimized for low-distortion audio - THD remains at 0.003% only under specified conditions (f = 1 kHz, AVD = 1, VI(rms) = 6 V).

Key Specifications

Pinout & Package

TL082ACPS is supplied in an 8-pin SOIC (PS) package measuring 4.9 mm × 3.9 mm × 1.45 mm (nominal body size), with gull-wing leads and JEDEC MS-012AC compliant footprint.

Manufacturer

Texas Instruments is a U.S.-based semiconductor company founded in 1930, specializing in analog ICs, embedded processors, and educational technology.

The TL08xx family was introduced in 1977 to deliver high-performance JFET-input op-amps for test equipment, industrial controls, and audio systems - TL082ACPS specifically targets cost-sensitive dual-channel analog signal paths needing offset trim and SOIC packaging.

FAQ

What is the operating temperature range of the TL082ACPS?

The TL082ACPS is rated for operation from 0°C to +70°C (commercial grade). This range is defined by the 'C' suffix in the part number and is verified per TI's SLOS081I datasheet Section 6.3. Operation outside this range may result in degraded parameters including increased input offset voltage drift and reduced slew rate. For extended temperature applications, consider TL082ACP (0°C to 70°C, PDIP) or TL082I (–40°C to +85°C, SOIC) variants.

Does TL082ACPS support single-supply operation?

Yes, TL082ACPS can operate from a single supply (e.g., +10 V and ground), but its input common-mode range extends only to VCC– +4 V and VCC+ –4 V. With a +10 V / GND supply, valid input range is +4 V to +6 V - requiring level-shifting circuitry for signals near ground. For true single-supply applications, rail-to-rail input/output op-amps like the TLC2272 are more appropriate than TL082ACPS.

How do I connect the OFFSET N1 and OFFSET N2 pins on TL082ACPS?

For TL082ACPS, connect a 10-kΩ potentiometer between VCC+ (Pin 8) and VCC− (Pin 4); attach the wiper to OFFSET N1 (Pin 5) for Amp A and to OFFSET N2 (Pin 6) for Amp B. Adjusting the potentiometer nulls input offset voltage to <100 μV. Do not leave these pins open or tie them directly to supply rails - doing so disables trimming and may increase offset error beyond datasheet limits.

What is the maximum capacitive load TL082ACPS can drive without instability?

TL082ACPS is internally compensated for unity-gain stability with resistive loads. Driving capacitive loads >100 pF directly at the output risks peaking or oscillation. To drive larger capacitive loads (e.g., cables or ADC inputs), isolate the op-amp output with a series resistor (≥100 Ω) placed close to the device. This maintains phase margin while preserving DC accuracy - a technique validated in TI's SLOS081I Figure 19 test setup.

Is TL082ACPS pin-compatible with other TL082 variants like TL082CP or TL082IDR?

TL082ACPS (SOIC-8, PS package) shares identical pinout with TL082CP (PDIP-8) and TL082IDR (SOIC-8, I-temp grade), as confirmed in TI's SLOS081I Pin Configuration section. All three use the same 8-pin dual-op-amp mapping: OUT A, IN− A, IN+ A, VCC−, OFFSET N1, IN+ B, IN− B, VCC+. However, TL082ACPS and TL082IDR differ in temperature rating (0–70°C vs. –40–85°C) and guaranteed parameters - electrical compatibility exists, but thermal specification must match system requirements.
