Product details
Overview
TLC084CDR 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 signal conditioning and buffer stage in audio line drivers, industrial sensor interfaces, and automotive body control modules requiring rail-to-rail input capability down to ground.
For engineers reviewing the TLC084CDR datasheet, TLC084CDR pinout, TLC084CDR application, or TLC084CDR equivalent, this page provides verified package mapping (SOIC-14), confirmed shutdown functionality per channel, measured noise performance (8.5 nV/√Hz), and real-world load-driving capability under 5 V and 12 V supply conditions.
Technical Context
The TLC084CDR integrates a low-noise CMOS front end with a high-current bipolar output stage, enabling simultaneous high input impedance (>1 GΩ differential), low input offset voltage (≤3000 µV over full temperature range), and robust output sourcing/sinking (57 mA/55 mA). Its architecture supports stable unity-gain operation with ≥32° phase margin into 50 pF loads at 5 V supply.
Each of its four independent amplifiers features dedicated shutdown pins (1SHDN, 2SHDN) enabling selective channel disable with 125 µA/channel quiescent current in shutdown mode. The device operates across 0°C to 70°C (C-suffix) and meets specified AC performance-including 10 MHz gain-bandwidth product and <0.012% THD+N at 1 kHz-under both 5 V and 12 V supply conditions.
Key Specifications

| Supply Voltage Range | 4.5 V to 16 V - enables direct interface with 5 V and 12 V system rails without level-shifting |
| Bandwidth | 10 MHz - supports audio band and fast transient response in active filters and driver stages |
| Output Drive | ±57 mA - drives 600 Ω loads directly, eliminating need for external buffer transistors |
| Input Offset Voltage | ≤3000 µV (full range) - ensures precision DC-coupled gain accuracy in sensor signal chains |
| Shutdown Current | 125 µA/channel - reduces total system power by >93% when unused channels are disabled |
| Input Noise Voltage | 8.5 nV/√Hz @ 1 kHz - preserves SNR in low-level analog front ends such as microphone preamps |
Pinout & Package
Package: SOIC-14 (D package), tape-and-reel (R suffix), rated for 0°C to 70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - capable of sourcing 57 mA or sinking 55 mA into resistive or capacitive loads |
| 2 | 1IN− | Inverting input of Amp A - high-impedance CMOS node (≥1 GΩ) for precision feedback networks |

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 (6 mV max), no shutdown, BiFET process | Lacks per-channel power control; unsuitable for battery-powered or thermally constrained designs requiring dynamic channel disable | Select TL084CDR only if cost sensitivity outweighs need for bandwidth, noise, or power management features |
| OPA4134UA | Lower output drive (±20 mA), no shutdown, FET input, 8 MHz bandwidth, lower noise (4.8 nV/√Hz) | Better noise performance but insufficient drive for 600 Ω loads; not pin-compatible with TLC084CDR SOIC-14 layout | Choose OPA4134UA when ultra-low noise dominates over output current requirements and PCB redesign is acceptable |
Compared with TL084CDR and OPA4134UA, the TLC084CDR uniquely balances 10 MHz bandwidth, ±57 mA drive, and per-channel shutdown in a drop-in SOIC-14 footprint - making it the only option among the three that simultaneously satisfies high-fidelity audio drive, industrial sensor buffering, and low-power multiplexed system requirements.

FAQ
What is the operating temperature range for the TLC084CDR?
The TLC084CDR is rated for 0°C to 70°C ambient operation (C-suffix grade). This commercial temperature range is validated across all electrical specifications including bandwidth, output drive, and input offset voltage, ensuring consistent performance in office, lab, and non-extreme industrial environments where thermal management is controlled.
Does the TLC084CDR support true single-supply operation with input signals down to ground?
Yes, the TLC084CDR supports true single-supply operation with a common-mode input voltage range extending from GND to VDD–2 V. This allows direct interfacing with ground-referenced sensors, DAC outputs, or microcontroller GPIOs without level-shifting circuitry - a key differentiator from legacy TL08x devices.
How does the shutdown feature work on the TLC084CDR?
The TLC084CDR provides independent shutdown control for Channels A and B via Pins 5 (1SHDN) and 10 (2SHDN). Applying ≤0.8 V to either pin disables the corresponding amplifier, reducing its supply current to 125 µA/channel while leaving other channels fully operational - enabling dynamic power optimization in multi-channel systems.
What is the maximum capacitive load the TLC084CDR can drive stably?
The TLC084CDR maintains ≥32° phase margin into 50 pF capacitive loads at 5 V supply, as confirmed in the datasheet's phase margin vs. load capacitance curves. For heavier loads (e.g., >100 pF), external series resistance (typically 10–50 Ω) at the output is recommended to preserve stability without degrading bandwidth.
Is the TLC084CDR pin-compatible with the TL084CDR?
No, the TLC084CDR and TL084CDR are not pin-compatible. While both use SOIC-14 packages, the TLC084CDR includes dedicated shutdown pins (Pins 5 and 10) absent in the TL084CDR, which instead uses those pins for NC or alternate functions. PCB layout must be redesigned to accommodate TLC084CDR's shutdown interface.
