Product details
Overview
TLC084IPWPR from Texas Instruments is a quad-channel BiMOS operational amplifier optimized for single-supply operation across 4.5 V to 16 V, delivering 10 MHz bandwidth, ±57 mA output drive, and 16 V/µs positive slew rate. It serves as a high-output-drive upgrade to TL08x in audio line drivers, sensor signal conditioning, and industrial analog front-ends requiring rail-to-rail input (GND to VDD–2 V) and robust load driving.
For engineers reviewing the TLC084IPWPR datasheet, TLC084IPWPR pinout, TLC084IPWPR application, or TLC084IPWPR equivalent, key selection criteria include its 20-pin TSSOP package with integrated shutdown pins per channel, ultralow 125 µA/channel shutdown current, and guaranteed performance over –40°C to 125°C for automotive and industrial control systems.
Technical Context
The TLC084IPWPR employs a BiMOS architecture combining CMOS input stage (1000 GΩ differential input resistance, 8.5 nV/√Hz input noise) with bipolar output stage to achieve high-speed, high-current capability. Its four independent amplifiers share no internal coupling-crosstalk remains below –120 dB at 1 kHz-enabling simultaneous use in multi-channel instrumentation without interference.
Each channel features dedicated shutdown control (SHDN pins 5 and 8), enabling selective channel disable with 0.15 µs turn-on and 1.3 µs turn-off times. The device operates with common-mode input range extending to ground and supports unity-gain stable operation into 50 pF capacitive loads, verified by 32° phase margin at CL = 50 pF and RL = 10 kΩ.
Key Specifications

| 17, 19 | No Connect (NC) | Unbonded pins; must remain floating per TI design - no PCB traces or vias |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Supports GND-referenced inputs and outputs down to 0.5 V, eliminating dual-rail complexity in portable and automotive systems |

| High-output current | Delivers ±57 mA while maintaining <0.7 V VOL at 50 mA, enabling direct drive of relays, LEDs, or low-Z cables |
| Low input noise | 8.5 nV/√Hz at 1 kHz allows clean amplification of µV-level sensor signals (e.g., thermocouples, strain gauges) |
| Wide temperature range | Specified performance from –40°C to 125°C ensures reliability in engine control units and motor drives without derating |
Applications
| Audio Line Driver | Sensor Signal Conditioning |

IC Role / Device Role / Timing Role: Output buffer and level shifter ensuring full-scale accuracy and load regulation across varying field device impedances. Use Value: ±57 mA drive sustains 4–20 mA compliance over 1 kΩ loop resistance; 10 MHz bandwidth prevents phase lag in PID control loops. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL084CDR | Lower bandwidth (3 MHz), lower output drive (±10 mA), no shutdown, wider VIO (6 mV max), BiFET process | Not suitable for high-speed or high-current applications; lacks thermal robustness beyond 70°C | Select only for cost-sensitive, non-automotive designs where speed and drive are secondary |
| OPA4134UA | Higher precision (250 µV VIO max), lower noise (8 nV/√Hz), no shutdown, SO-14 package, ±18 V max supply | Requires dual supply; unsuitable for single-supply 5 V/12 V systems with ground-referenced sensors | Prefer for high-fidelity audio or precision lab equipment where shutdown and single-rail operation are unnecessary |
Compared with TL084CDR and OPA4134UA, the TLC084IPWPR uniquely combines single-supply operation, per-pair shutdown, and high-output drive in an extended temperature grade-making it the only option among the three qualified for automotive body control modules and industrial motor drives.

FAQ
What is the maximum operating temperature range for the TLC084IPWPR?
The TLC084IPWPR is rated for continuous operation from –40°C to 125°C, meeting AEC-Q100 stress test requirements for automotive under-hood applications. This extended temperature range is confirmed in the "Recommended Operating Conditions" table of the SLOS254F datasheet, and applies to all electrical specifications unless otherwise noted for the I-suffix grade.
Does the TLC084IPWPR support true rail-to-rail input?
The TLC084IPWPR does not support rail-to-rail input; its common-mode input voltage range is specified as GND to VDD–2 V. At VDD = 5 V, this means VICR extends from 0 V to 3 V; at VDD = 12 V, it spans 0 V to 10 V. This ground-sensing capability enables single-supply interfacing with sensors and microcontrollers referenced to system ground.
How many independent shutdown controls does the TLC084IPWPR provide?
The TLC084IPWPR provides two independent shutdown controls: pin 5 (1/2SHDN) disables channels 1 and 2 simultaneously, and pin 8 (3/4SHDN) disables channels 3 and 4. Each control is active-low with a 0.8 V maximum threshold, allowing direct interface with standard logic outputs without level-shifting circuitry.
What is the typical output impedance of the TLC084IPWPR at 10 kHz?
The typical closed-loop output impedance of the TLC084IPWPR is 0.25 Ω at 10 kHz with AV = 10, as measured under standard test conditions (VDD = 5 V, TA = 25°C). This low impedance ensures minimal gain error and improved load regulation when driving variable or reactive loads such as transmission lines or ADC input networks.
Can the TLC084IPWPR drive a 600 Ω audio load at full output swing?
Yes-the TLC084IPWPR can drive a 600 Ω load to ±3.5 V at VDD = 5 V (VOH ≥ 3.2 V, VOL ≤ 0.7 V at ±50 mA), delivering >10 VPP into professional audio standards. Its 10 MHz bandwidth and low THD+N (0.005% at 1 kHz, 8 VPP, RL = 10 kΩ) preserve fidelity, making it suitable for line driver stages in automotive head units and broadcast equipment.
