Product details
Overview
TLC084CPWPR from Texas Instruments is a quad-channel BiMOS operational amplifier optimized for single-supply, high-output-drive applications. It delivers 10 MHz bandwidth, ±57 mA output drive, 16 V/µs positive slew rate, and operates from 4.5 V to 16 V - enabling robust signal conditioning in audio line drivers and industrial sensor interfaces.
For engineers reviewing the TLC084CPWPR datasheet, TLC084CPWPR pinout, TLC084CPWPR application, or TLC084CPWPR equivalent, key selection criteria include guaranteed ground-sensing input common-mode range (VICR = GND to VDD–2 V), ultralow 125 µA/channel shutdown current, and TSSOP-20 package compatibility with space-constrained PCB layouts.
Technical Context
The TLC084CPWPR integrates a low-noise CMOS front end with a high-current bipolar output stage, enabling simultaneous high impedance (>1 GΩ differential input resistance), low input noise (8.5 nV/√Hz), and strong capacitive load drive capability (up to 50 pF with stable phase margin). Its BiMOS architecture eliminates dual-supply dependency while maintaining dc precision.
It features independent channel shutdown control via dedicated SHDN pins (pins 5 and 10), supports rail-to-rail output swing under moderate loads, and maintains 80 dB CMRR and PSRR across 4.5–16 V supply range - making it suitable for mixed-signal systems where supply headroom and noise immunity are critical.
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 logic inputs without external buffers. |
| Slew Rate | +16 V/µs / –19 V/µs - supports fast transient response in pulse amplification and active filter stages. |
| Supply Range | 4.5 V to 16 V - operates directly from unregulated 5 V, 12 V, or battery-derived rails without LDO pre-regulation. |
| Input Offset Voltage | Max 3000 µV (full temp range) - ensures minimal dc error in precision gain stages and sensor front ends. |
| Shutdown Current | 125 µA/channel - reduces system standby power by >93% versus active mode (1.9 mA/channel). |
| Input Noise | 8.5 nV/√Hz @ 1 kHz - preserves signal integrity in low-level analog paths such as microphone preamps. |
Pinout & Package
TLC084CPWPR uses a 20-pin TSSOP (PWP) package with exposed thermal pad, rated for 0°C to 70°C operation and optimized for automated assembly and thermal dissipation (θJA = 26.1°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 11, 13 | Inverting Input (1IN–, 2IN–, 3IN–, 4IN–) | Differential input nodes accepting negative feedback or signal inversion per channel. |
| 2, 4, 12, 14 | Non-inverting Input (1IN+, 2IN+, 3IN+, 4IN+) | Reference-side inputs for unity-gain buffers or non-inverting configurations. |
| 5, 10 | Channel Shutdown (1/2SHDN, 3/4SHDN) | CMOS-compatible logic inputs disabling respective amplifier pairs to reduce quiescent current. |
| 6, 15 | Positive Supply (VDD) | Single supply rail connection shared across all four channels; decoupling required at each VDD pin. |
| 7, 16 | Ground (GND) | Common reference for inputs, outputs, and shutdown logic; separate GND pins minimize crosstalk. |
| 8, 9, 17, 18 | Output (1OUT, 2OUT, 3OUT, 4OUT) | Class-AB output stages capable of sourcing/sinking ±57 mA into resistive or capacitive loads. |
| 19, 20 | No Connect (NC) | Unbonded pins; must remain floating per TI design - no routing or grounding permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Ground-sensing input range | VICR includes GND (0 V), enabling direct interfacing with single-ended sensors and microcontroller ADCs. |
| Independent dual-pair shutdown | Two SHDN pins allow selective deactivation of channel groups - critical for dynamic power management in multi-stage signal chains. |
| High-output-drive BiMOS topology | Combines CMOS input impedance (>1 GΩ) with bipolar output current capability (±57 mA), eliminating need for external driver stages. |
| Low-noise, wide-bandwidth performance | 8.5 nV/√Hz input voltage noise and 10 MHz GBW support high-fidelity audio and fast-settling instrumentation loops. |
| TSSOP-20 thermal enhancement | Exposed thermal pad improves heat dissipation - supports continuous 4-channel operation at full output drive without derating. |

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), higher input offset (10 mV max), no shutdown function, JFET input (higher IB). | Lacks rail-to-rail input, unsuitable for ground-referenced sensors; no power gating capability. | Select when cost sensitivity outweighs performance needs and shutdown is unnecessary. |
| OPA4134UA | Lower noise (4.5 nV/√Hz), lower supply current (2 mA/ch), no shutdown, SOIC-14 package (fewer pins). | Missing dedicated SHDN pins and TSSOP-20 footprint; limited output drive (±25 mA). | Prefer for ultra-low-noise audio preamps where power gating and high drive are secondary. |
Compared with TL084CDR and OPA4134UA, the TLC084CPWPR uniquely combines ground-sensing input range, integrated shutdown, and ±57 mA drive in a space-efficient TSSOP-20 - making it optimal for compact, power-aware industrial and automotive signal chains requiring robust output capability.

FAQ
What is the operating temperature range for the TLC084CPWPR?
The TLC084CPWPR is specified for commercial operation from 0°C to 70°C. This temperature grade is indicated by the 'C' suffix in the part number and aligns with standard industrial ambient requirements where active cooling or extreme environmental sealing is not needed. The device maintains full parameter compliance across this range, including input offset voltage, slew rate, and output drive capability.
Does the TLC084CPWPR support rail-to-rail input or output operation?
The TLC084CPWPR supports rail-to-rail output swing under typical loads but does not offer rail-to-rail input. Its common-mode input voltage range extends from GND to VDD–2 V, enabling true ground-referenced operation - a key advantage over older op-amps that require input bias above GND. Output swing reaches within ~0.5 V of each rail at ±50 mA load, verified per datasheet test conditions.
How many independent shutdown controls does the TLC084CPWPR provide?
The TLC084CPWPR provides two independent shutdown controls: pin 5 (1/2SHDN) disables channels 1 and 2, while pin 10 (3/4SHDN) disables channels 3 and 4. Each control accepts standard CMOS logic levels (VIH ≥ 2 V, VIL ≤ 0.8 V) and reduces the corresponding pair's supply current to 125 µA per channel. This dual-pair architecture enables granular power management in multi-function analog subsystems.
What is the maximum capacitive load the TLC084CPWPR can drive stably?
The TLC084CPWPR maintains stable operation with up to 50 pF of capacitive load at unity gain, as confirmed by phase margin measurements (≥32° at CL = 50 pF, RL = 10 kΩ). For heavier loads, external isolation resistors (e.g., 10–100 Ω in series with the output) are recommended to preserve stability - particularly in driving long cables or ADC input capacitance in data acquisition systems.
Is the TLC084CPWPR pin-compatible with other quad op-amps in TSSOP-20 packages?
No, the TLC084CPWPR is not pin-compatible with generic TSSOP-20 quad op-amps. Its pinout - including dual SHDN inputs, duplicated VDD/GND pins, and NC terminals - is specific to the TLC08x family. Substituting with alternatives like OPA4134UA or LM324 requires PCB layout revision due to differing pin assignments, supply configurations, and absence of shutdown functionality.
