Product details
Overview
TLC085CN 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 TLC085CN datasheet, TLC085CN pinout, TLC085CN application, or TLC085CN equivalent, key selection criteria include its shutdown capability, rail-to-rail input common-mode range (GND to VDD–2 V), low 8.5 nV/√Hz input noise, and verified performance across –40°C to 125°C.
Technical Context
The TLC085CN integrates four independent BiMOS op-amps with CMOS front-end (high impedance, low input bias current) and bipolar output stage (high current drive). Its architecture supports stable operation with capacitive loads up to 50 pF and provides 37° phase margin at 12 V supply.
It features active shutdown control per channel pair (pins 8 and 16), enabling power-gating of two amplifiers simultaneously. Input offset voltage is specified at ≤3000 µV over full temperature range, and common-mode rejection ratio reaches 110 dB at 25°C.
Key Specifications

|---|---|
| Channels | 4 independent amplifiers in one package |

| Output Drive | ±57 mA sourcing/sinking - drives 600 Ω loads directly, eliminating external buffers |
| Slew Rate | +16 V/µs / –19 V/µs - enables fast settling for pulse and transient signals |
| Supply Range | 4.5 V to 16 V single supply - compatible with 5 V and 12 V industrial rails |
| Input Noise | 8.5 nV/√Hz at 1 kHz - preserves SNR in precision analog front-ends |
| Shutdown Current | 125 µA per channel - reduces system standby power by >93% vs active mode |

| 12 | VDD | Positive supply rail shared across all channels |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Operates with inputs down to GND and up to VDD–2 V - simplifies level-shifting in single-supply systems |
| High-output-current bipolar stage | Delivers ±57 mA into resistive loads - eliminates need for discrete output transistors in line drivers |
| Low-power shutdown mode | Reduces per-channel supply current to 125 µA - enables dynamic power management in multi-stage analog chains |
| Wide temperature range support | Specified from –40°C to +125°C - suitable for under-hood automotive and industrial control environments |
| BiMOS process integration | Combines CMOS input (pA-level bias current) with bipolar output (high drive) - achieves both precision and power in one die |
Applications
| Audio Line Driver | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Driving balanced/unbalanced audio outputs from DACs or microcontrollers into 600 Ω professional audio equipment. IC Role / Device Role / Timing Role: Quad op-amp configured as two differential line drivers and two active filters. Use Value: ±57 mA output drive ensures full-swing into 600 Ω loads at 5 V supply; 8.5 nV/√Hz noise preserves dynamic range. | Use Scenario: Amplifying low-level signals from RTDs, strain gauges, or thermocouples in PLC analog input modules. IC Role / Device Role / Timing Role: Instrumentation-grade signal conditioning with programmable gain and filtering before ADC sampling. Use Value: Rail-to-rail input allows direct interface to grounded sensors; 10 MHz bandwidth supports anti-aliasing filter design up to ~1 MHz. |
| Automotive Body Control Module | Programmable Logic Controller Analog Output |
Use Scenario: Driving solenoids, relays, or LED arrays in 12 V automotive body electronics with thermal protection. IC Role / Device Role / Timing Role: High-current buffer stage between MCU GPIO and load, with shutdown for sleep-mode current reduction. Use Value: Operates across –40°C to +125°C; shutdown pins reduce quiescent current to <1 mA total for four channels during vehicle sleep. | Use Scenario: Providing isolated 0–10 V or 4–20 mA loop outputs in industrial PLC analog output cards. IC Role / Device Role / Timing Role: Voltage-to-current converter and output driver stage with precise offset and gain control. Use Value: Low 60 µV typical input offset minimizes zero-error; 110 dB CMRR rejects common-mode noise on long field wiring. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL084CN | Lower bandwidth (3 MHz), no shutdown, higher input offset (10 mV max), ±10 mA output drive | Lacks power-gating capability; unsuitable for battery-powered or thermally constrained designs requiring dynamic power control | Select TL084CN only when cost is primary constraint and performance requirements are relaxed |
| OPA4134UA | FET-input, lower noise (8 nV/√Hz), no shutdown, ±20 mA output, 8 MHz bandwidth, higher supply current (4 mA/ch) | Better noise performance but cannot drive heavy loads; no integrated shutdown requires external logic | Choose OPA4134UA for ultra-low-distortion audio where output current <20 mA suffices |
Compared with TL084CN and OPA4134UA, the TLC085CN uniquely balances high output drive, integrated shutdown, wide supply range, and extended temperature operation - making it optimal for industrial and automotive analog subsystems requiring both precision and power delivery.

FAQ
What is the operating temperature range for the TLC085CN?
The TLC085CN is rated for operation from –40°C to +125°C, meeting extended industrial and automotive under-hood requirements. This specification is guaranteed across all electrical parameters in the datasheet's "Recommended Operating Conditions" table, and applies to the N-package (16-pin PDIP) variant explicitly listed in TI's SLOS254F datasheet.
Does the TLC085CN support rail-to-rail input operation?
The TLC085CN supports rail-to-rail input common-mode voltage from GND to VDD–2 V, enabling direct interfacing with grounded sensors and single-supply DACs. It does not support true rail-to-rail input (i.e., VDD is excluded), nor rail-to-rail output - its output swing is typically within 1.5 V of each rail under load.
How does the shutdown function work on the TLC085CN?
The TLC085CN uses two dedicated active-low shutdown pins: pin 8 (1/2SHDN) disables channels 1 and 2, and pin 16 (3/4SHDN) disables channels 3 and 4. When pulled ≤0.8 V, each pair enters ultralow-power mode drawing ≤125 µA per channel, with output high-impedance state maintained.
What is the maximum capacitive load the TLC085CN can drive stably?
The TLC085CN maintains stability with capacitive loads up to 50 pF when driving a 10 kΩ load, as confirmed by phase margin measurements (37° at 12 V supply). For heavier loads (>100 pF), external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to prevent peaking or oscillation.
Is the TLC085CN pin-compatible with other quad op-amps like the TL084 or LM324?
No, the TLC085CN is not pin-compatible with TL084CN or LM324N. Its 16-pin DIP layout includes dedicated shutdown pins (8 and 16) and different pin assignments (e.g., GND on pin 4, VDD on pin 12), whereas TL084CN uses 14-pin DIP and LM324N uses 14-pin DIP with GND on pin 4 and VCC on pin 14. PCB redesign is required for substitution.
