Product details
Overview
TLC075AIN from Texas Instruments is a quad-channel, single-supply operational amplifier with 10 MHz gain-bandwidth product, ±50 mA high-output-drive capability, and 16 V/μs positive slew rate. It operates from 4.5 V to 16 V, features ultralow-power shutdown mode (125 μA/channel), and is housed in a 16-pin plastic DIP package rated for −40°C to 125°C industrial temperature range - ideal for precision audio line drivers and sensor signal conditioning in harsh environments.
For engineers reviewing the TLC075AIN datasheet, TLC075AIN pinout, TLC075AIN application, or TLC075AIN equivalent, this page delivers verified electrical specifications, functional pin mapping, real-world use cases in automotive and industrial systems, and two validated alternative op-amps with documented performance trade-offs.
Technical Context
The TLC075AIN uses TI's patented LBC3 BiCMOS process to combine a high-input-impedance CMOS front end (1000 GΩ differential input resistance) with a high-current bipolar output stage, enabling both low input noise (7 nV/√Hz at 1 kHz) and robust drive capability (57 mA sourcing, 55 mA sinking). Its rail-to-rail input common-mode range (0.5 V to VDD−0.8 V) and internal shutdown logic support flexible single-supply system integration.
Designed as a BiFET upgrade path, it delivers 300% higher bandwidth and 60% lower voltage noise than TL07x predecessors while maintaining compatibility with legacy PCB footprints for DIP-16 packages. The device includes independent channel enable/disable via shared 1/2SHDN and 3/4SHDN pins, supporting power-gated multi-stage amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 4 independent op-amp channels in one IC |
| Gain-bandwidth product | 10 MHz - supports stable unity-gain buffers up to ~10 MHz or closed-loop gains of 10 at 1 MHz |
| Output drive current | ±50 mA - drives low-impedance loads (e.g., 600 Ω audio lines, capacitive DAC buffers) without external transistors |
| Slew rate | +16 V/μs / −19 V/μs - enables fast settling for pulse and video signals with minimal distortion |
| Input offset voltage | Max 2000 μV over full temperature range - suitable for medium-precision DC-coupled applications (e.g., thermocouple amps) |
| Supply current per channel | 1.9 mA typical at 5 V - enables low-power multichannel signal chains; drops to 125 μA in shutdown |
| Operating temperature | −40°C to +125°C - qualified for under-hood automotive and industrial control environments |

Applications
| Audio Line Driver | Industrial Sensor Signal Conditioning |
|---|---|
|
Use Scenario: Driving balanced/unbalanced analog audio signals over 600 Ω cables in automotive infotainment head units. IC Role / Device Role / Timing Role: Quad-channel buffer and level shifter - Channels 1 & 2 form differential driver pair; Channels 3 & 4 provide active termination and DC offset correction. Use Value: ±50 mA output drive ensures full 2 VPP swing into 600 Ω with <0.012% THD+N at 1 kHz, eliminating need for discrete output transistors. |
Use Scenario: Amplifying low-level outputs from 4–20 mA current-loop sensors in PLC analog input modules. IC Role / Device Role / Timing Role: Precision transimpedance amplifier and programmable gain stage - each channel processes one sensor channel with independent gain/offset calibration. Use Value: 7 nV/√Hz input noise and 2000 μV max VIO enable 12-bit effective resolution across −40°C to 125°C without recalibration. |
| Automotive Battery Monitoring | Multi-Stage Active Filter |
|
Use Scenario: Real-time voltage monitoring of 12 V battery and auxiliary rails in ADAS domain controllers. IC Role / Device Role / Timing Role: High-voltage comparator interface and fault-detection amplifier - Channels 1–3 monitor VBAT, VACC, and VIGN; Channel 4 enables shutdown during deep sleep. Use Value: 16 V absolute max supply rating and −40°C to 125°C operation ensure reliability across cold crank and hot soak conditions. |
Use Scenario: Implementing 4-pole low-pass filtering for anti-aliasing before SAR ADC sampling in motor control feedback loops. IC Role / Device Role / Timing Role: Cascaded Sallen-Key stages - each channel forms one 2nd-order stage; dual shutdown pins allow dynamic filter order reduction. Use Value: 10 MHz GBW and 16 V/μs slew rate support 100 kHz cutoff with <1% passband ripple and <100 ns group delay variation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC074AIN | No shutdown functionality; identical pinout, GBW (10 MHz), noise (7 nV/√Hz), and drive (±50 mA), but lacks SHDN pins 8 and 16 | Requires external power gating for low-power modes; unsuitable where dynamic channel disable is needed | Select TLC074AIN only when shutdown is unnecessary and BOM simplification is prioritized over power flexibility |
| OPA4134UA | Lower drive (±10 mA), lower supply current (4 mA/ch), higher precision (100 μV VIO max), no shutdown, SO-14 package | Better for high-accuracy audio preamps; insufficient for driving heavy loads like relays or long cables | Choose OPA4134UA when ultra-low distortion (<0.00008% THD+N) and dc accuracy outweigh output current needs |
Compared with TLC075AIN, TLC074AIN removes shutdown capability but retains identical AC performance and footprint, while OPA4134UA trades output drive and power efficiency for superior dc precision and audio fidelity - making TLC075AIN the only option supporting both high-current drive and configurable power states in DIP-16.

FAQ
What is the maximum supply voltage rating for the TLC075AIN?
The TLC075AIN has an absolute maximum supply voltage of 17 V, with recommended operating range from 4.5 V to 16 V. Operation at 16 V is fully characterized across −40°C to 125°C, delivering 10.5 V high-level output at 50 mA sink/source while maintaining 10 MHz gain-bandwidth product and 16 V/μs slew rate. Exceeding 17 V risks permanent damage.
Does the TLC075AIN support rail-to-rail input operation?
Yes, the TLC075AIN supports rail-to-rail input common-mode voltage from 0.5 V above GND to VDD−0.8 V. At VDD = 12 V, this spans 0.5 V to 11.2 V; at VDD = 5 V, it covers 0.5 V to 4.2 V. This allows direct interfacing with microcontroller ADC references, DAC outputs, and other single-supply circuitry without level-shifting components.
How does the shutdown feature work on the TLC075AIN?
The TLC075AIN implements dual independent shutdown: Pin 8 (1/2SHDN) disables Channels 1 and 2; Pin 16 (3/4SHDN) disables Channels 3 and 4. A logic-low voltage ≤0.8 V places the respective channels into ultralow-power state (125 μA/channel), reducing total supply current from 7.6 mA (all active) to 250 μA (all shut down). Both pins must be pulled high (>2 V) to enable full operation.
What is the output current capability of the TLC075AIN at 12 V supply?
At VDD = 12 V, the TLC075AIN delivers 57 mA sourcing (VOH = 10.5 V at IOH = −50 mA) and 55 mA sinking (VOL = 0.6 V at IOL = 50 mA) across −40°C to 125°C. Short-circuit output current exceeds ±150 mA. This enables direct driving of 600 Ω audio lines, 1 kΩ potentiometers, and capacitive loads up to 1000 pF without stability issues.
Is the TLC075AIN pin-compatible with other devices in the TLC07x family?
Yes, the TLC075AIN shares the same 16-pin DIP (N) package and pinout with TLC074AIN and TLC074ID, differing only in shutdown functionality. Pins 1–7, 9–15 match exactly; Pin 8 (1/2SHDN) and Pin 16 (3/4SHDN) are unique to TLC075 variants. This allows drop-in replacement of TLC074AIN when shutdown capability is added to existing designs.
