Product details
Overview
TLC084AID 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 operates from –40°C to 125°C and is used in high-fidelity audio line drivers, industrial sensor signal conditioning, and automotive body control modules requiring rail-to-rail input capability and robust load driving.
For engineers reviewing the TLC084AID datasheet, TLC084AID pinout, TLC084AID application, or TLC084AID equivalent, key selection criteria include guaranteed ground-sensing common-mode input range (VICR = GND to VDD–2 V), ultralow 125 µA/channel shutdown current, and 20-pin TSSOP package compatibility with space-constrained PCB layouts.
Technical Context
The TLC084AID integrates a low-noise CMOS front end with a high-drive bipolar output stage in TI's LBC3 BiCMOS process, enabling simultaneous high impedance (>1 GΩ differential input resistance), low input noise (8.5 nV/√Hz), and strong output sourcing/sinking (57 mA/55 mA). Its architecture supports stable unity-gain operation with ≥32° phase margin into 50 pF loads.
It features independent shutdown control per channel pair (pins 5 and 10), allowing selective channel disable without affecting others. The device ensures DC performance across temperature: input offset voltage ≤2000 µV (max) over –40°C to 125°C, with 1.2 µV/°C drift coefficient and 80 dB minimum CMRR at full operating range.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464AIPW | Lower bandwidth (6.4 MHz), lower output drive (±30 mA), but rail-to-rail I/O and lower supply current (550 µA/channel). | Better suited for ultra-low-power battery-operated sensors; insufficient for 600 Ω line driving or fast pulse generation. | Select TLV2464AIPW only when power budget <1 mW/channel dominates over speed/load requirements. |
| OPA4340UA | Higher precision (50 µV max VIO), lower noise (5.5 nV/√Hz), but limited output drive (±20 mA) and narrower supply (2.7–5.5 V). | Ideal for high-resolution medical instrumentation; incompatible with 12 V industrial rails or high-current loads. | Choose OPA4340UA when sub-100 µV offset and <10 nV/√Hz noise are mandatory, and supply is fixed at 3.3 V or 5 V. |
Compared with TLV2464AIPW and OPA4340UA, the TLC084AID uniquely balances wide bandwidth, high output current, and extended temperature operation-making it the only option among the three qualified for 12 V automotive body control and industrial 600 Ω line driver use cases.

FAQ
What is the maximum operating temperature range for the TLC084AID?
The TLC084AID is rated for operation from –40°C to +125°C, meeting extended industrial temperature requirements. This specification is guaranteed across all electrical parameters in the datasheet, including input offset voltage (≤2000 µV max), supply current (≤3.5 mA/channel), and output drive (±57 mA), making it suitable for under-hood automotive and factory-floor industrial environments where thermal stress is critical.
Does the TLC084AID support true single-supply operation with inputs referenced to ground?
Yes, the TLC084AID supports true single-supply operation with inputs referenced to ground. Its common-mode input voltage range extends from GND to VDD–2 V across the full temperature range, enabling direct interfacing with ground-referenced sensors, DACs, and microcontroller outputs without level-shifting circuitry-a key differentiator from legacy TL08x devices.
How many independent shutdown controls does the TLC084AID provide, and how are they assigned?
The TLC084AID provides two independent active-low shutdown controls: pin 5 (1/2SHDN) disables channels 1 and 2, while pin 10 (3/4SHDN) disables channels 3 and 4. Each control reduces the respective channel's supply current to ≤250 µA (typical 125 µA), enabling flexible power management in multi-channel systems without affecting active sections of the TLC084AID.
What is the typical output current capability of the TLC084AID at 12 V supply?
At 12 V supply, the TLC084AID delivers ±57 mA sourcing and sinking capability per channel, verified across temperature (–40°C to 125°C). This allows direct driving of 600 Ω audio lines, capacitive loads up to 1000 pF, and industrial actuators-without external boost transistors-while maintaining VOH ≥10.3 V and VOL ≤0.65 V under full load.
Is the TLC084AID pin-compatible with other devices in the TLC08x family?
No, the TLC084AID is not pin-compatible with other TLC08x variants. It uses a 20-pin TSSOP (PWP) package, whereas TLC080/1/2/3 use 8- or 14-pin SOIC/DIP, and TLC085 uses a 16-pin DIP or 20-pin TSSOP with different pin assignments (e.g., dedicated shutdown per channel vs. paired shutdown). PCB layout must be designed specifically for the TLC084AID's 20-pin footprint and pinout.
