Product details
Overview
TLC084CPWP from Texas Instruments is a quad-channel BiMOS operational amplifier optimized for single-supply operation (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 for TL08x in audio line drivers, sensor signal conditioning, and industrial analog front-ends requiring rail-to-rail input capability down to ground.
For engineers reviewing the TLC084CPWP datasheet, TLC084CPWP pinout, TLC084CPWP application, or TLC084CPWP equivalent, key selection criteria include its 20-pin TSSOP PowerPAD™ package, shutdown control per channel pair, 8.5 nV/√Hz input noise, and guaranteed common-mode input range including GND - critical for low-voltage single-supply systems.
Technical Context
The TLC084CPWP integrates a CMOS front end for ultralow input bias current (≤100 pA) and bipolar output stage for high-current drive (±55 mA). Its architecture supports stable operation with capacitive loads up to 50 pF and features internal offset nulling pins for precision applications.
Each of the four amplifiers includes independent shutdown control logic (pins 5 and 10), enabling dynamic power management. The device operates across 0°C to 70°C (C-suffix) and meets 130 dB supply rejection at DC, making it suitable for mixed-signal environments with noisy power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables accurate amplification of signals up to audio and low-speed data rates without gain roll-off. |
| Output Drive | ±57 mA - drives heavy loads like 600 Ω audio lines or multiple ADC inputs without external buffers. |
| Slew Rate | +16 V/µs / –19 V/µs - supports fast transient response in pulse amplification and active filtering. |
| Input Noise | 8.5 nV/√Hz at 1 kHz - preserves SNR in low-level sensor signal chains (e.g., thermocouples, strain gauges). |
| Supply Range | 4.5 V to 16 V - compatible with 5 V, 12 V, and battery-powered systems without level-shifting. |
| Input Offset | 60 µV typical - reduces DC error in precision instrumentation and closed-loop control feedback paths. |
| Shutdown Current | 125 µA per channel - cuts quiescent power by >93% during idle periods in portable or energy-conscious designs. |
Pinout & Package
Package: 20-pin TSSOP with PowerPAD™ thermal pad (PWP suffix), designed for enhanced heat dissipation in high-output-drive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 12, 14 | Inverting Input (–) | Accepts differential input signals; high impedance (>1 GΩ) minimizes loading on preceding stages. |
| 2, 4, 11, 13 | Non-inverting Input (+) | Supports unity-gain buffer or differential configurations; common-mode range includes GND. |
| 5, 10 | Channel Pair Shutdown | Active-low logic control: pulls supply current to 125 µA/channel when ≤0.8 V (TTL-compatible). |
| 6, 7, 15, 16 | Output | Capable of sourcing/sinking ±55 mA into resistive or moderate capacitive loads (≤50 pF). |
| 8 | VDD | Single positive supply input; decoupling required within 1 cm for stability at full bandwidth. |
| 17 | GND | Analog ground reference; tied to PowerPAD™ thermal pad for lowest thermal resistance (θJC = 1.40°C/W). |
| 9, 18–20 | No Connect | Internally unconnected; must remain floating or grounded per layout guidelines to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (low IB, low noise) with bipolar output (high IOUT, low Zo) - eliminates need for external driver stages. |
| Ground-Sensing Input Range | VICR extends to GND at all supply voltages - enables direct interfacing with 0–V sensors and microcontroller ADC references. |
| Per-Pair Shutdown Control | Two independent SHDN pins (5 & 10) disable channels 1/2 and 3/4 separately - supports multi-rate signal processing with dynamic power scaling. |
| PowerPAD™ Thermal Enhancement | Thermal resistance θJC = 1.40°C/W - sustains 4.79 W power dissipation in compact layouts without heatsinks. |
| Low THD+N | 0.005% at 1 kHz (VDD = 12 V, RL = 10 kΩ) - maintains fidelity in audio line drivers and DAC output buffers. |
Applications
| Audio Line Driver | Sensor Signal Conditioning |
|---|---|
Use Scenario: Driving balanced/unbalanced 600 Ω professional audio outputs from DACs or microcontrollers. IC Role / Device Role / Timing Role: Quad op-amp configured as two differential line drivers (channels 1/2 and 3/4), each with matched gain and phase. Use Value: ±57 mA output drive ensures full swing into 600 Ω loads; 8.5 nV/√Hz noise preserves dynamic range above 110 dB. | Use Scenario: Amplifying low-level mV-range signals from RTDs, thermocouples, or bridge sensors in industrial PLC modules. IC Role / Device Role / Timing Role: Precision instrumentation amplifier front-end with offset nulling pins and rail-to-ground input capability. Use Value: 60 µV typical VIO and 1.2 µV/°C drift minimize calibration burden; shutdown mode reduces system standby power. |
| Industrial Analog Output | Multi-Channel Data Acquisition |
Use Scenario: Generating programmable 0–10 V or 4–20 mA analog outputs in programmable logic controllers. IC Role / Device Role / Timing Role: Voltage-to-current converter and output buffer with high open-loop gain (120 dB) and wide supply range. Use Value: 10 MHz GBW and 16 V/µs slew rate support fast settling (<0.4 µs) for DAC update rates up to 1 MSPS. | Use Scenario: Simultaneous buffering and anti-alias filtering of 4-channel sensor inputs before multiplexed ADC sampling. IC Role / Device Role / Timing Role: Quad unity-gain follower providing high-Z input isolation and low-output impedance drive to ADC sample-and-hold. Use Value: 0.25 Ω closed-loop output impedance ensures minimal gain error; per-pair shutdown allows channel-specific power gating. |
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), no shutdown, higher VIO (3 mV max), BiFET process. | Lacks single-supply optimization and output drive; unsuitable for 600 Ω loads or ground-referenced sensors. | Select only if legacy compatibility or cost sensitivity outweighs performance requirements. |
| OPA4134UA | FET-input, lower noise (8 nV/√Hz), no shutdown, SO-14 package, higher price. | Superior audio SNR but lacks PowerPAD™ thermal performance and per-pair shutdown for power-aware DAQ systems. | Prefer for ultra-low-distortion audio where thermal density and dynamic power control are secondary. |
Compared with TL084CDR and OPA4134UA, the TLC084CPWP uniquely combines BiMOS output drive, ground-sensing inputs, per-pair shutdown, and PowerPAD™ thermal efficiency - enabling compact, high-fidelity, single-supply analog subsystems without external support circuitry.

FAQ
What is the operating temperature range for the TLC084CPWP?
The TLC084CPWP is rated for 0°C to 70°C (C-suffix), verified per TI's SLOS254F datasheet. This commercial-grade range supports indoor industrial controls, consumer audio equipment, and test instrumentation where ambient conditions remain within specification. Extended temperature variants (e.g., TLC084IPWP) operate from –40°C to 125°C.
Does the TLC084CPWP support true single-supply operation with input voltage down to ground?
Yes, the TLC084CPWP guarantees a common-mode input voltage range (VICR) from GND to VDD–2 V across its full operating range. At VDD = 5 V, VICR spans 0 V to 3 V; at VDD = 12 V, it spans 0 V to 10 V - enabling direct interfacing with ground-referenced sensors and microcontroller I/O without level-shifting circuitry.
How does the shutdown feature work on the TLC084CPWP?
The TLC084CPWP has two independent shutdown pins: pin 5 controls channels 1 and 2, and pin 10 controls channels 3 and 4. When either pin is pulled ≤0.8 V (TTL low), the corresponding pair enters ultralow-power mode with IDD(SHDN) = 125 µA per channel. Both pins must be ≥2 V to enable full operation.
What is the thermal performance advantage of the PWP package in the TLC084CPWP?
The TLC084CPWP's 20-pin TSSOP PowerPAD™ (PWP) package achieves θJC = 1.40°C/W and θJA = 26.1°C/W, enabling 4.79 W power dissipation under proper PCB layout. This allows sustained ±55 mA output drive per channel without thermal derating - a 3× improvement over standard SOIC packages in space-constrained industrial modules.
Can the TLC084CPWP drive a 600 Ω load at full output swing?
Yes, the TLC084CPWP delivers ±57 mA output current, supporting full ±4.5 V swing into 600 Ω at VDD = 12 V (VOH = 10.5 V, VOL = 0.45 V). Test data confirms <0.005% THD+N at 1 kHz under these conditions - meeting professional audio line driver requirements per AES3 standards.
