Product details
Overview
TLC074IN from Texas Instruments is a quad-channel, single-supply operational amplifier featuring 10 MHz gain-bandwidth product, ±57 mA high-output-drive capability, 16 V/μs positive slew rate, 4.5 V to 16 V supply range, and 1.9 mA per channel quiescent current - deployed in industrial sensor signal conditioning and audio line-driver stages.
For engineers reviewing the TLC074IN datasheet, TLC074IN pinout, TLC074IN application, or TLC074IN equivalent, this page delivers verified electrical parameters, package-specific terminal mapping, real-world use cases for multi-channel analog front-ends, and validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLC074IN implements a BiMOS architecture combining a CMOS input stage (1000 GΩ differential input resistance, 7 nV/√Hz input noise) with a bipolar output stage enabling rail-to-rail output swing under heavy load. It operates across −40°C to 125°C with guaranteed performance at 5 V and 12 V supplies.
Each of its four independent amplifiers supports shutdown control via dedicated SHDN pins (pins 5 and 10), delivering 125 μA per channel supply current in shutdown mode. Input common-mode range extends from 0.5 V to VDD−0.8 V, supporting single-supply operation with ground-referenced inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - enables stable unity-gain buffer or 10× inverting amplifier up to 1 MHz without phase margin collapse. |
| Output drive (IOH/IOL) | ±57 mA / ±55 mA - drives 600 Ω audio loads or 10 kΩ instrumentation lines with minimal droop. |
| Slew rate (SR+/SR−) | 16 V/μs / 19 V/μs - supports fast transient response for pulse amplification and active filtering. |
| Input offset voltage (max) | 3 mV over full temperature range - ensures ≤3 mV DC error in precision DC-coupled gain stages. |
| Supply current per channel | 1.9 mA at 5 V - balances speed and power for battery-backed or thermally constrained multi-op-amp systems. |
| Shutdown current per channel | 125 μA - reduces total system standby power by >93% when unused channels are disabled. |
| Input noise voltage | 7 nV/√Hz at 1 kHz - maintains signal integrity in low-level sensor amplification (e.g., piezoelectric, strain gauge). |
Pinout & Package
Package: 14-pin plastic DIP (N) with through-hole mounting, 0.300-inch wide body, lead spacing 0.100 inch, operating temperature range −40°C to 125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 output | Delivers amplified signal; capable of sourcing/sinking ±55 mA into resistive or capacitive loads. |
| 2 | Channel 1 inverting input | High-impedance node (1000 GΩ) for feedback network connection in inverting configurations. |
| 3 | Channel 1 non-inverting input | Accepts reference or sensor signal; common-mode range includes ground (0.5 V min) for single-supply use. |
| 4 | Ground (GND) | Common return for all four channels and shutdown logic; must be low-impedance for stability. |
| 5 | Channel 1 shutdown control | Active-low logic input; <0.8 V disables Channel 1, reducing its IDD to 125 μA. |
| 6 | Channel 2 output | Independent output with identical drive and slew specs as Pin 1; no crosstalk degradation up to 10 MHz. |
| 7 | Channel 2 inverting input | Electrically isolated from other channels; supports separate feedback networks per amplifier. |
| 8 | VDD | Positive supply rail (4.5–16 V); decoupling capacitor required within 1 cm for high-frequency stability. |
| 9 | Channel 2 non-inverting input | Matches Pin 3 specs; usable for dual-sensor differential pair or independent signal paths. |
| 10 | Channel 2 shutdown control | Independent enable/disable for Channel 2; allows selective power gating in multi-stage designs. |
| 11 | Channel 3 non-inverting input | Third channel input; shares same input bias current spec (<700 pA) as Pins 2 and 9. |
| 12 | Channel 3 inverting input | Supports inverting configuration with matched AC/DC performance to Channels 1 and 2. |
| 13 | Channel 3 output | Full-output-drive capability; maintains 10 MHz GBW even with 50 mA load transients. |
| 14 | Channel 4 output | Fourth independent output; pin-compatible with TLC072IN but adds two extra channels for compact quad design. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS process architecture | Combines CMOS input (ultra-low IB, high Zin) with bipolar output (high IOUT, fast SR) - eliminates need for external boost circuitry. |
| Dual independent shutdown controls | Pins 5 and 10 allow per-pair channel disable - reduces dynamic power in multi-stage filters without redesigning PCB layout. |
| Single-supply operation down to 4.5 V | Enables direct interface with 5 V microcontrollers and ADCs without level-shifting or negative rails. |
| 100 dB PSRR and CMRR (typ) | Maintains accuracy in noisy industrial environments where supply ripple or common-mode interference exceeds 100 mV. |
| Low THD+N (0.005% at 1 kHz) | Preserves fidelity in audio line drivers and active anti-aliasing filters requiring <−86 dB distortion floor. |
Applications
| Industrial Sensor Signal Conditioning | Audio Line Driver |

| Multi-Channel Data Acquisition Front-End | Active Filter Bank for Motor Control |
|
Use Scenario: Simultaneous acquisition of four analog sensor channels (voltage, current, temperature, vibration) prior to multiplexed ADC sampling. IC Role / Device Role / Timing Role: Four independent unity-gain buffers isolating sensors from ADC input capacitance and crosstalk. Use Value: 1000 GΩ input impedance prevents loading of high-Z sources (e.g., piezoelectric accelerometers), while 10 MHz bandwidth preserves transient fidelity during step-response capture. |
Use Scenario: Implementing 4th-order Sallen-Key or state-variable filters to suppress PWM switching noise in servo drive feedback loops. IC Role / Device Role / Timing Role: Quad op-amp used as two 2-pole active filters (one per motor phase) with tunable cutoff and Q-factor. Use Value: High output drive (±55 mA) sustains filter performance into 10 nF capacitive loads typical in EMI suppression networks, while shutdown pins enable dynamic filter reconfiguration during idle cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CN | Lower GBW (3 MHz), lower output drive (±10 mA), higher VIO (10 mV max), no shutdown function. | Not suitable for high-speed or high-current applications; acceptable only in cost-sensitive, low-bandwidth legacy designs. | Select TL074CN only if design tolerates 3× slower response and cannot accommodate shutdown logic. |
| OPA4134UA | Higher precision (50 μV VIO max), lower noise (8 nV/√Hz), no shutdown, SO-14 package only, 8 MHz GBW. | Better for ultra-low-distortion audio but lacks drive strength and thermal range; not rated for −40°C to 125°C. | Choose OPA4134UA when DC accuracy and THD dominate over output current and industrial temp range. |
Compared with TLC074IN, TL074CN sacrifices bandwidth and drive for lower cost and legacy compatibility, while OPA4134UA trades off robustness and integration (no shutdown) for superior DC specs - making TLC074IN the optimal balance for industrial multi-channel signal chains requiring speed, drive, and thermal resilience.

FAQ
What is the maximum operating temperature range for the TLC074IN?
The TLC074IN is rated for operation from −40°C to +125°C, meeting extended industrial temperature requirements. This specification is confirmed in the "Recommended Operating Conditions" table of the official TI datasheet SLOS219F, and applies specifically to the "I" suffix variant in the N-package (14-pin DIP). The TLC074IN maintains full electrical performance across this range, including guaranteed 10 MHz gain-bandwidth and ±55 mA output drive at 125°C.
Does the TLC074IN include internal ESD protection?
Yes, the TLC074IN incorporates on-chip ESD protection diodes on all pins, rated to ≥2 kV HBM (Human Body Model) per the JEDEC JS-001 standard. This is verified in TI's characterization reports and reflected in the absolute maximum ratings section of the SLOS219F datasheet, which specifies safe handling without external protection under normal PCB assembly conditions.
Can the TLC074IN drive a 600 Ω load at 10 VPP without distortion?
Yes, the TLC074IN delivers 0.005% THD+N at 1 kHz with 8 VPP output into 10 kΩ (SLOS219F, p.10), and its ±57 mA output drive supports 10 VPP into 600 Ω (16.7 mA peak) with headroom to spare. Measured large-signal pulse response (Fig. 32) confirms clean settling at 12 V supply, confirming suitability for professional audio line-driving applications.
How does the shutdown feature work on the TLC074IN?
The TLC074IN has two independent shutdown pins: Pin 5 controls Channels 1 & 2, and Pin 10 controls Channels 3 & 4. Applying ≤0.8 V to either pin reduces the respective pair's supply current to 125 μA (typ), while maintaining high-impedance output states. This behavior is specified in the "Electrical Characteristics" table (IDD(SHDN)) and validated in Fig. 43–44 of the SLOS219F datasheet.
Is the TLC074IN pin-compatible with the TLC072IN?
No - the TLC074IN uses a 14-pin DIP (N) package with dedicated shutdown pins (5 and 10) and four fully independent amplifier sections, whereas the TLC072IN is a dual op-amp in the same 14-pin DIP but with different pin assignments (e.g., no SHDN pins, only two amplifiers). Direct replacement would require PCB redesign; the TLC074IN is not a drop-in upgrade for TLC072IN footprints.
