Product details
Overview
TLC084CD 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 (VICR includes GND) and robust load driving.
For engineers reviewing the TLC084CD datasheet, TLC084CD pinout, TLC084CD application, or TLC084CD equivalent, key selection criteria include its 4-channel SOIC-14 package, shutdown capability per channel, 8.5 nV/√Hz input noise, and guaranteed performance over 0°C to 70°C - critical for cost-sensitive industrial and consumer systems needing wide supply range and high current sourcing/sinking.
Technical Context
The TLC084CD integrates a low-noise CMOS front end with a high-drive bipolar output stage, enabling both ultrahigh input impedance (>1 GΩ) and ±57 mA output current. Its BiMOS architecture ensures stable operation with capacitive loads up to 50 pF while maintaining ≥32° phase margin at unity gain.
Each of the four independent amplifiers features dedicated shutdown pins (1SHDN, 2SHDN), allowing per-channel power control without affecting adjacent channels. The device operates with common-mode input voltage spanning from ground to VDD–2 V, supporting true single-supply signal acquisition in sensor interfaces and data acquisition systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC084ID | Same architecture and pinout, but rated for –40°C to 125°C industrial temperature range; higher max VIO (3000 µV vs 60 µV typical) | Required for under-hood automotive or outdoor industrial deployments where ambient exceeds 70°C | Select TLC084ID only if extended temperature operation is mandatory; otherwise TLC084CD offers lower typical offset and cost |
| TL084CD | JFET-input quad op-amp with 3 MHz GBW, ±10 mA output, 16 V/µs slew rate; no shutdown function; higher input noise (18 nV/√Hz) | Legacy designs prioritizing low cost over drive strength or noise; unsuitable for driving low-Z loads or precision sensor amps | Choose TL084CD only for non-critical, low-frequency (<100 kHz), low-current applications where BiMOS advantages are unnecessary |
Compared with TLC084ID, the TLC084CD trades extended temperature rating for lower typical input offset and cost; versus TL084CD, it delivers 3.3× more bandwidth, 5.7× higher output current, and half the input noise - making it superior for modern high-fidelity, high-drive analog systems.

FAQ
What is the operating temperature range for the TLC084CD?
The TLC084CD is specified for commercial operation from 0°C to 70°C. This range is clearly defined in the Recommended Operating Conditions table of the official datasheet (SLOS254F), and all electrical characteristics - including bandwidth, output drive, and input offset - are guaranteed across this interval. Applications outside this range require the TLC084ID variant.
Does the TLC084CD support true single-supply operation with input voltage down to ground?
Yes, the TLC084CD supports true single-supply operation with a common-mode input voltage range extending to ground (GND). Per the datasheet, VICR is specified as GND to VDD–2 V at VDD = 5 V and 12 V, enabling direct interfacing with sensors or microcontrollers that output 0–VDD signals without level-shifting circuitry.
How does the shutdown feature work on the TLC084CD?
The TLC084CD provides independent shutdown control for Channels 1 and 2 via Pins 5 (1SHDN) and 10 (2SHDN). When pulled ≤0.8 V, each channel enters ultralow-power mode drawing only 125 µA; the output goes high-impedance. Pins 11–14 correspond to Channels 3 and 4, which lack dedicated shutdown pins in the SOIC-14 package - consistent with the TLC084CD's documented pinout.
What is the maximum capacitive load the TLC084CD can drive stably?
The TLC084CD is characterized for stable operation with up to 50 pF capacitive load, maintaining ≥32° phase margin at unity gain per the Phase Margin vs Load Capacitance curves (Figures 19–20). Driving larger loads requires external isolation resistance (e.g., 10–100 Ω in series with output) to prevent peaking or oscillation, especially in cable-driving applications.
Is the TLC084CD pin-compatible with the TL084CD?
No, the TLC084CD is not pin-compatible with the TL084CD. While both are quad op-amps in SOIC-14 packages, the TLC084CD uses Pins 5 and 10 for 1SHDN and 2SHDN functions, whereas TL084CD assigns those pins to NC and 3IN+ respectively. Substituting them without board revision will cause functional failure due to incorrect pin mapping and missing shutdown logic.
