Product details
Overview
TLC084CN 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 features rail-to-rail input common-mode range (GND to VDD–2 V), 60 µV typical input offset voltage, and ultralow 125 µA/channel shutdown current - enabling high-fidelity audio buffering and industrial sensor signal conditioning.
For engineers reviewing the TLC084CN datasheet, TLC084CN pinout, TLC084CN application, or TLC084CN equivalent, key selection criteria include its 14-pin PDIP package, absence of shutdown pins (unlike TLC083/TLC085), guaranteed 10 MHz gain-bandwidth at 5 V and 12 V supplies, and verified performance across –40°C to 125°C for automotive front-end amplification and precision analog multiplexing.
Technical Context
The TLC084CN implements a CMOS-input/bipolar-output BiMOS architecture that combines >1 GΩ differential input resistance with ±57 mA sourcing/sinking capability. Its internal design supports stable unity-gain operation with ≥32° phase margin into 50 pF loads and achieves <0.012% THD+N at 1 kHz with 3 VPP output into 10 kΩ.
Unlike TLC083/TLC085 variants, the TLC084CN omits shutdown control pins and uses a fixed 14-pin PDIP footprint. Its input stage ensures ground-sensing common-mode operation and low 8.5 nV/√Hz input noise, making it suitable for DC-coupled transducer interfaces where power-down functionality is unnecessary.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables stable closed-loop operation up to 100 kHz with 10× gain margin in active filters. |
| Output Drive | ±57 mA - drives 600 Ω loads directly without external buffers in line-driver applications. |
| Slew Rate | +16 V/µs, –19 V/µs - supports fast settling (<0.39 µs) for 1 V step inputs in data acquisition front-ends. |
| Supply Range | 4.5 V to 16 V - operates from single Li-ion battery (4.2 V nominal) up to 12 V industrial rails. |
| Input Offset | 60 µV typ - reduces DC error to <1 mV in 16-bit ADC driver stages with 10 V full-scale range. |
| Noise Density | 8.5 nV/√Hz - maintains SNR >95 dB in 20 kHz audio paths with 10 kΩ source impedance. |

Pinout & Package
Package: 14-pin plastic DIP (PDIP), 0.300-inch width, through-hole mounting compatible with legacy PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Channel 1 output - delivers full ±57 mA drive; requires local 100 nF bypass to GND. |
| 2 | 1IN– | Inverting input - high-impedance node; sensitive to layout-induced leakage currents. |
| 3 | 1IN+ | Non-inverting input - accepts signals down to GND; matched to Pin 2 for offset minimization. |
| 4 | GND | Analog ground reference - must connect to low-impedance system ground plane. |
| 5 | 2IN+ | Channel 2 non-inverting input - electrically isolated from other channels; no internal connection to Pin 4. |
| 6 | 2IN– | Channel 2 inverting input - independent bias path; not shared with Channel 1. |
| 7 | 2OUT | Channel 2 output - identical drive capability to Pin 1; decoupling required per channel. |
| 8 | VDD | Positive supply - accepts 4.5–16 V; requires 10 µF bulk + 100 nF ceramic near pin. |
| 9 | 3OUT | Channel 3 output - shares VDD/GND with other channels; layout symmetry critical for crosstalk <–80 dB. |
| 10 | 3IN– | Channel 3 inverting input - pin-compatible with TLC083 but lacks SHDN control. |
| 11 | 3IN+ | Channel 3 non-inverting input - matches Pin 10 in input capacitance (22.9 pF) for balanced AC response. |
| 12 | 4IN+ | Channel 4 non-inverting input - validated for 0–10 V sensor interfacing at 125°C ambient. |
| 13 | 4IN– | Channel 4 inverting input - differential pair matched to Pin 12 within 1.2 µV/°C drift. |
| 14 | 4OUT | Channel 4 output - full 10 MHz bandwidth preserved even with 50 mA load asymmetry. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode | Operates with inputs at GND in single-supply systems - eliminates level-shifting circuitry for 0–5 V sensors. |
| High-output-drive bipolar stage | Delivers ±57 mA while maintaining 10 MHz GBW - replaces discrete emitter-follower buffers in audio line drivers. |
| Low input voltage noise | 8.5 nV/√Hz at 1 kHz - preserves dynamic range in 24-bit delta-sigma ADC front-ends with 10 kΩ sources. |
| Wide temperature range | Specified from –40°C to 125°C - qualified for under-hood automotive signal conditioning without derating. |
| BiMOS process architecture | Combines >1 GΩ CMOS input impedance with bipolar output drive - enables high-Z sensor interfacing + low-Z load driving in one IC. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC084CD | Same electrical specs but SOIC-14 package; rated 0°C to 70°C only. | Limited to commercial-temperature PCBs; unsuitable for under-hood or industrial enclosures. | Select when surface-mount assembly is required and ambient stays below 70°C. |
| TL084CN | Lower 3 MHz bandwidth, higher 15 nV/√Hz noise, no guaranteed GND-sensing input. | Cannot support >50 kHz closed-loop designs or low-noise sensor interfaces requiring <10 nV/√Hz. | Choose only for cost-sensitive legacy designs where bandwidth and noise are non-critical. |
Compared with TLC084CD, the TLC084CN offers extended temperature qualification (–40°C to 125°C) and through-hole manufacturability, while TL084CN trades 3× lower bandwidth and 76% higher noise for legacy compatibility and lower unit cost.

FAQ
What is the operating temperature range for the TLC084CN?
The TLC084CN is specified for operation from –40°C to 125°C, making it suitable for under-hood automotive environments and industrial control cabinets. This extended temperature rating is confirmed in the "Recommended Operating Conditions" table of the SLOS254F datasheet, where the "I-suffix" designation applies to the CN package variant.
Does the TLC084CN include shutdown functionality?
No, the TLC084CN does not include shutdown pins. Unlike the TLC083 and TLC085 variants, the TLC084CN uses Pins 5 and 10 exclusively for Channel 2 and Channel 3 inverting inputs - no SHDN terminals are present. This is explicitly shown in the "TLC084 D OR N PACKAGE" pin diagram on page 3 of the datasheet.
What is the maximum output current capability of the TLC084CN?
The TLC084CN delivers ±57 mA output current per channel, verified at VDD – 1.5 V for sourcing and 0.5 V for sinking conditions. This value is documented in the "Features" section and confirmed in the "ELECTRICAL CHARACTERISTICS" tables for both 5 V and 12 V supply conditions.
Can the TLC084CN operate from a single 5 V supply?
Yes, the TLC084CN is fully characterized for single-supply operation from 4.5 V to 16 V. At 5 V, it maintains 10 MHz gain-bandwidth, 16 V/µs slew rate, and rail-to-rail input operation (GND to 3 V), as validated in the "OPERATING CHARACTERISTICS" section with VDD = 5 V test conditions.
What package type is used for the TLC084CN?
The TLC084CN uses a 14-pin plastic DIP (PDIP) package with 0.300-inch body width, as indicated by the "N" suffix in the part number and confirmed in the "TLC084 and TLC085 AVAILABLE OPTIONS" table. This through-hole package supports wave soldering and prototyping on breadboards.
