Product details
Overview
TLC074AIN 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, delivers ultralow input offset voltage (max 2 mV over temperature), and supports industrial-grade operation from −40°C to 125°C in a 14-pin PDIP package - used in precision sensor signal conditioning and audio line drivers.
For engineers reviewing the TLC074AIN datasheet, TLC074AIN pinout, TLC074AIN application, or TLC074AIN equivalent, this page provides verified electrical parameters, shutdown-mode behavior, thermal performance data, and real-world design guidance for single-supply op-amp selection in automotive and industrial analog front-ends.
Technical Context
The TLC074AIN uses TI's LBC3 BiCMOS process to integrate a high-impedance CMOS input stage with a bipolar output driver, enabling both low input bias current (≤700 pA) and robust output current drive (±55 mA). Its rail-to-rail input common-mode range extends from 0.5 V to VDD−0.8 V at 5 V supply and 0.5 V to VDD−0.8 V at 12 V supply.
Each channel features independent shutdown control via dedicated SHDN pins (pins 5 and 10), allowing selective channel disablement with 125 μA per-channel quiescent current in shutdown mode. The device maintains stable unity-gain operation with ≥32° phase margin into 50 pF capacitive loads and exhibits <0.012% THD+N at 1 kHz with 3 VPP output into 10 kΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - enables stable closed-loop operation up to 10× gain at 1 MHz or unity gain at 10 MHz. |
| Output drive current | ±55 mA - drives heavy loads such as 600 Ω audio lines or capacitive DAC buffers without external boost stages. |
| Slew rate (SR+) | 16 V/μs - supports fast settling of large-signal transients in active filters and pulse amplifiers. |
| Input offset voltage (max) | 2000 μV over −40°C to 125°C - ensures DC accuracy in precision instrumentation and sensor interfaces. |
| Supply voltage range | 4.5 V to 16 V - compatible with 5 V, 12 V, and wide-input industrial rails without level-shifting. |
| Shutdown current (per channel) | 125 μA - reduces total system power by >93% when unused channels are disabled. |
| Input noise voltage | 7 nV/√Hz at 1 kHz - preserves SNR in low-level microphone preamps and strain-gauge amplifiers. |
Pinout & Package
Package: 14-pin Plastic DIP (N), body width 0.300 inch, lead pitch 0.100 inch, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Channel 1 output - capable of sourcing/sinking ±55 mA into resistive or moderate capacitive loads. |
| 2 | 1IN− | Inverting input - high-impedance CMOS node (≥1 TΩ differential resistance) for precision feedback networks. |
| 3 | 1IN+ | Non-inverting input - accepts common-mode voltages from 0.5 V to VDD−0.8 V, enabling single-supply sensor interfacing. |
| 4 | GND | Analog ground reference - must be connected to clean system ground plane to minimize PSRR degradation. |
| 5 | 1SHDN | Channel 1 shutdown control - logic-high (>2 V) enables; logic-low (<0.8 V) disables channel with 125 μA standby current. |
| 6 | VDD | Positive supply - powers all four channels; decoupling capacitor (0.1 μF ceramic) required within 1 cm. |
| 7 | 2OUT | Channel 2 output - electrically identical to Pin 1; independent of Channel 1 operation. |
| 8 | 2IN− | Channel 2 inverting input - isolated from other channels; no internal crosstalk above −140 dB at 10 kHz. |
| 9 | 2IN+ | Channel 2 non-inverting input - same input voltage range and bias current specs as Pin 3. |
| 10 | 2SHDN | Channel 2 shutdown control - independent logic control allows mixed active/shutdown channel configurations. |
| 11 | 3IN+ | Channel 3 non-inverting input - shares same BiCMOS input structure; matched offset and drift vs. Pins 2/3/8/12/14. |
| 12 | 3IN− | Channel 3 inverting input - pin-compatible with standard quad op-amp layouts; no NC or dummy pins. |
| 13 | 3OUT | Channel 3 output - fully specified for 50 mA load drive at VDD = 12 V with <100 ns turn-on time. |
| 14 | 4OUT | Channel 4 output - supports simultaneous multi-channel signal processing without inter-channel coupling. |
Key Features
| Feature | Design Value |

| Independent channel shutdown | Dedicated SHDN pins per pair (Pins 5 & 10) allow dynamic power scaling without affecting adjacent channels. |
| Low input noise density | 7 nV/√Hz at 1 kHz enables use in low-amplitude sensor amplification where noise floor dominates SNR. |
| Industrial temperature grade | Specified from −40°C to +125°C with guaranteed offset drift ≤1.2 μV/°C ensures stability in engine control or motor drive environments. |

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 bandwidth (3 MHz), higher input offset (10 mV max), no shutdown function, 2.8 mA/ch supply current. | Lacks rail-to-rail input, unsuitable for low-voltage single-supply sensors; limited drive strength (±10 mA). | Select TL074CN only for cost-sensitive legacy designs where bandwidth and output drive are not critical. |
| OPA4134UA | Lower noise (4.5 nV/√Hz), lower distortion (0.00008% THD+N), but only ±20 mA output drive and no shutdown pins. | Better for ultra-low-noise audio, but cannot replace TLC074AIN in high-current line driving or power-sensitive shutdown scenarios. | Choose OPA4134UA when noise and distortion dominate requirements, and output current demand is ≤20 mA. |
Compared with TL074CN and OPA4134UA, the TLC074AIN uniquely combines industrial temperature rating, per-pair shutdown control, and ±55 mA drive in a PDIP package - making it optimal for space-constrained, power-aware, high-fidelity analog subsystems requiring field-replaceable through-hole mounting.

FAQ
What is the operating temperature range for the TLC074AIN?
The TLC074AIN is rated for operation from −40°C to +125°C, meeting industrial-grade environmental requirements. This specification is validated across all electrical parameters including input offset voltage, supply current, and output drive capability - ensuring reliable performance in under-hood automotive or factory-floor control applications where ambient temperatures exceed 100°C.
Does the TLC074AIN support true rail-to-rail input operation?
No, the TLC074AIN does not support rail-to-rail input. Its common-mode input voltage range is specified from 0.5 V to VDD−0.8 V at both 5 V and 12 V supplies. This allows operation near ground but excludes the negative rail (GND) and leaves ~0.8 V headroom below VDD - sufficient for most single-supply sensor interfaces but requiring level-shifting for signals extending to GND or VDD.
How much output current can each channel of the TLC074AIN deliver?
Each channel of the TLC074AIN delivers up to 57 mA sourcing (IOH) at VDD−1.5 V and 55 mA sinking (IOL) at 0.5 V above GND, tested at 25°C with VDD = 5 V or 12 V. These values are maintained across the full −40°C to 125°C range, enabling direct drive of LEDs, relays, and low-impedance audio loads without external buffers.
What is the purpose of the SHDN pins on the TLC074AIN?
The TLC074AIN has two dedicated shutdown pins: Pin 5 (1SHDN) controls Channels 1 and 2, and Pin 10 (2SHDN) controls Channels 3 and 4. When pulled low (<0.8 V), each pair enters shutdown mode drawing only 125 μA per channel - reducing total quad quiescent current from 7.6 mA to 500 μA. This enables dynamic power management in battery-operated or thermally constrained systems.
Can the TLC074AIN be used in place of the TL074 in existing designs?
The TLC074AIN is pin-compatible with TL074CN in the 14-pin PDIP package and shares identical pinout and footprint. However, it offers superior bandwidth (10 MHz vs. 3 MHz), lower input offset (2 mV vs. 10 mV), and added shutdown functionality. Designers must verify that the higher slew rate and output drive do not induce instability in existing compensation networks - especially with capacitive loads >50 pF.
