Product details
Overview
TLC084ID 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 slew rate. It operates over –40°C to 125°C and is used in high-fidelity audio line drivers, industrial sensor signal conditioning, and automotive body control modules requiring rail-to-rail input capability and robust load driving.
For engineers reviewing the TLC084ID datasheet, TLC084ID pinout, TLC084ID application, or TLC084ID equivalent, key selection criteria include guaranteed ground-sensing common-mode input range (VICR = GND to VDD–2 V), ultralow shutdown current (125 µA/channel), and 14-pin SOIC packaging with channel-independent shutdown control.
Technical Context
The TLC084ID integrates a CMOS front end for ultra-high input impedance (>1 GΩ) and low input bias current (<700 pA), paired with a bipolar output stage enabling ±57 mA sourcing/sinking into heavy loads. 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 amplifiers features independent shutdown pins (1SHDN, 2SHDN, 3/4SHDN), allowing selective channel disable without affecting others. The device supports true single-supply operation with VICR extending to ground and VOH/VOL specified down to 0.5 V from rails at full output current.
Key Specifications

| Bandwidth | 10 MHz - enables stable closed-loop operation up to 100 kHz with gain ≥100. |
| Output Drive | ±57 mA - drives 600 Ω loads directly without external buffers in audio and actuator interfaces. |
| Slew Rate | +16 V/µs, –19 V/µs - supports fast transient response in pulse amplification and active filtering. |
| Supply Range | 4.5 V to 16 V - compatible with 5 V, 12 V, and wide-input industrial power rails. |
| Input Offset Voltage | 3000 µV max (full temp range) - suitable for precision DC-coupled applications requiring <1 mV error. |
| Shutdown Current | 125 µA/channel - reduces system standby power by >93% vs active mode (1.9 mA/channel). |
| Common-Mode Range | GND to VDD–2 V - accepts 0 V input signals on single supply, eliminating level-shifting circuitry. |
Pinout & Package
Package: 14-pin SOIC (N), 3.9 mm × 8.7 mm, surface-mount, RoHS-compliant.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL084CD | Lower bandwidth (3 MHz), higher input offset (10 mV max), no shutdown function, dual-supply only (±15 V). | Not suitable for single-supply or low-power systems; limited to legacy designs with existing ±15 V rails. | Select TL084CD only if cost is primary constraint and performance requirements are relaxed. |
| OPA4134UA | Lower output drive (±10 mA), lower supply current (4 mA/channel), superior noise (8 nV/√Hz), no shutdown. | Better for low-noise audio but cannot drive heavy loads; lacks power management for portable devices. | Choose OPA4134UA when ultra-low distortion and wide dynamic range outweigh output current needs. |
Compared with TL084CD and OPA4134UA, the TLC084ID uniquely combines single-supply operation, per-channel shutdown, and high output drive-making it the only option among the three qualified for automotive body control and industrial sensor modules requiring both precision and power efficiency.

FAQ
What is the operating temperature range for the TLC084ID?
The TLC084ID is rated for operation from –40°C to +125°C, making it suitable for under-hood automotive applications, industrial control cabinets, and outdoor equipment where ambient temperatures exceed commercial-grade limits. This extended range is confirmed in the "Recommended Operating Conditions" table of the official SLOS254F datasheet, and applies to all electrical specifications unless otherwise noted.
Does the TLC084ID support true single-supply operation with input signals referenced to ground?
Yes, the TLC084ID supports true single-supply operation with a common-mode input voltage range (VICR) from GND to VDD–2 V. This allows direct connection of 0 V-referenced sensors (e.g., thermocouples, resistive bridges) without level-shifting circuitry. The specification is verified across the full –40°C to 125°C range and appears in both the "Recommended Operating Conditions" and "Electrical Characteristics" sections of the SLOS254F datasheet.
How many independent shutdown inputs does the TLC084ID have, and how are they assigned?
The TLC084ID has three dedicated shutdown control inputs: Pin 5 (1SHDN), Pin 6 (2SHDN), and Pin 13 (3/4SHDN). Pins 5 and 6 control Channels A and B individually; Pin 13 simultaneously disables Channels C and D. This configuration is explicitly shown in the "TLC084 D OR N PACKAGE" pin diagram on page 3 of the SLOS254F datasheet and enables flexible power sequencing in multi-channel systems.
What is the maximum output current capability of the TLC084ID per channel?
Each channel of the TLC084ID delivers ±57 mA continuous output current - +57 mA sourced at VDD–1.5 V and –55 mA sunk at 0.5 V - as specified in the "Features" section and confirmed in the "Electrical Characteristics" tables (VDD = 5 V and 12 V) of the SLOS254F datasheet. This rating holds across the full operating temperature range and enables direct driving of 600 Ω loads without external buffers.
Is the TLC084ID pin-compatible with standard quad op-amp footprints such as SOIC-14?
Yes, the TLC084ID uses a standard 14-pin SOIC (N) package with 1.27 mm pitch, matching industry-standard quad op-amp footprints. Its pinout follows TI's defined mapping for the TLC084 family (documented on page 3 of SLOS254F), and is electrically and mechanically compatible with PCB layouts designed for TL084, LM324, or OPA4340 in the same package. No board redesign is needed for drop-in replacement where performance requirements align.
