Product details
Overview
TL084ID from Texas Instruments is a quad JFET-input operational amplifier designed for precision analog signal conditioning in industrial and audio systems. It delivers 20 V/μs slew rate, 5.25 MHz gain-bandwidth product, ±1 mV typical input offset voltage, 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 TL084ID datasheet, TL084ID pinout, TL084ID application, or TL084ID equivalent, key selection considerations include its quad-channel FET-input architecture, 14-pin SOIC (D) package, guaranteed performance across –40°C to +125°C, and compatibility with single-supply or split-supply configurations up to 40 V total.
Technical Context
The TL084ID implements a high-impedance JFET differential input stage followed by a Class AB output stage with short-circuit protection. Its input stage supports common-mode voltage extending to VCC+, enabling operation in non-inverting configurations with inputs near the positive rail - a key advantage over bipolar-input op-amps.
It features integrated EMI/RF filters and 1.5 kV HBM ESD rating, making it suitable for noisy industrial environments. The device maintains stable unity-gain operation with capacitive loads up to 300 pF and exhibits 56° phase margin under standard test conditions (G = +1, RL = 10 kΩ, CL = 20 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables four independent amplification paths in one 14-pin SOIC package, reducing board space vs discrete solutions. |
| Slew Rate | 20 V/μs (typ) - supports fast transient response in active filters and wideband signal conditioning without distortion. |
| Gain-Bandwidth Product | 5.25 MHz - allows stable closed-loop operation up to ~100 kHz at G = 50, suitable for audio preamp and sensor interface stages. |
| Input Offset Voltage | ±1 mV (typ), ±4 mV (max) - ensures <0.1% DC error in 1 V full-scale instrumentation circuits at room temperature. |
| Common-Mode Input Range | Extends to VCC+ - permits direct sensing of signals referenced to the positive supply, e.g., high-side current monitoring. |
| Supply Voltage Range | ±2.25 V to ±20 V (or 4.5 V to 40 V single-ended) - accommodates both low-voltage portable designs and high-voltage industrial rails. |
| Input Bias Current | ±1 pA (typ) - minimizes voltage error in high-impedance sensor interfaces (e.g., piezoelectric transducers, pH electrodes). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL084CDR | Same quad JFET architecture but rated for 0°C to +70°C only; higher max input offset (10 mV) and lower CMRR (70 dB). | Restricted to commercial-grade applications; unsuitable for automotive or extended-temperature industrial use. | Select TL084ID when operation above +85°C or tighter DC accuracy is required. |
| OPA4134UA | Lower noise (8 nV/√Hz), lower distortion (0.00008%), but higher quiescent current (4 mA/ch) and narrower supply range (±4 V to ±18 V). | Better suited for ultra-low-noise audio; less optimal for battery-powered or high-voltage industrial systems. | Choose TL084ID for cost-sensitive, wide-supply, high-temp applications where 37 nV/√Hz noise is acceptable. |
Compared with TL084CDR and OPA4134UA, TL084ID uniquely balances extended temperature operation (–40°C to +125°C), rail-to-rail input capability, and low power (940 µA/ch), making it optimal for ruggedized embedded analog front-ends where thermal stability and supply flexibility outweigh ultra-low-noise requirements.

FAQ
What is the maximum operating temperature for TL084ID?
The TL084ID is specified for operation from –40°C to +125°C ambient temperature. This extended range is confirmed in Section 5.3 Recommended Operating Conditions of the official datasheet, where TL084H-grade devices (including TL084ID) list TA = –40°C to +125°C as the full specified temperature range. Derating applies above 100°C depending on PCB thermal design.
Does TL084ID support single-supply operation?
Yes, TL084ID supports true single-supply operation from 4.5 V to 40 V total supply voltage. Its common-mode input range extends to VCC+, allowing inputs to swing up to the positive rail, and its output can swing within ~210 mV of each rail under 10 kΩ load - enabling robust functionality in 5 V, 12 V, or 24 V systems without dual supplies.
What is the input offset voltage specification for TL084ID?
The TL084ID has a typical input offset voltage of ±1 mV and a maximum of ±4 mV at 25°C, with ±5 mV guaranteed over the full –40°C to +125°C temperature range. These values are explicitly listed in Table 5-7 (Electrical Characteristics: TL08xH) under the VOS parameter, confirming its suitability for precision DC-coupled applications.
Can TL084ID drive capacitive loads?
Yes, TL084ID is characterized to drive capacitive loads up to 300 pF while maintaining stability, as stated in the "CLOAD" parameter row of Section 5.7. It achieves 56° phase margin with 20 pF load under unity-gain conditions, and small-signal overshoot remains controlled up to 300 pF per Figure 5-23 and 5-24 in the datasheet.
Is TL084ID pin-compatible with other TL084 variants?
Yes, TL084ID uses the standard 14-pin SOIC (D) package and shares identical pinout with all TL084x variants in that package - including TL084CDR, TL084ACDR, and TL084BCDR. Pin functions match Table 4-5 exactly: pins 1/7/8/14 are outputs, pins 2/3/5/6/9/10/12/13 are inputs, and pins 4/11 are supplies.
