Product details
Overview
TLC074CN from Texas Instruments is a quad-channel, single-supply operational amplifier featuring 10 MHz gain-bandwidth product, ±57 mA high-output-drive capability, and 16 V/μs positive slew rate. It operates from 4.5 V to 16 V, draws only 1.9 mA per channel, and delivers ultralow input offset voltage (60 μV typ) - ideal for precision audio line drivers and industrial sensor signal conditioning.
For engineers reviewing the TLC074CN datasheet, TLC074CN pinout, TLC074CN application, or TLC074CN equivalent, this page provides verified package mapping (14-pin PDIP), confirmed shutdown control logic, real-world output drive limits at 5 V/12 V, and validated alternatives for single-supply op-amp replacement in space-constrained analog front-ends.
Technical Context
The TLC074CN uses TI's LBC3 BiCMOS process to integrate a CMOS input stage (ultrahigh impedance, 7 nV/√Hz noise) with a bipolar output stage (±57 mA drive). Its rail-to-rail input common-mode range (0.5 V to VDD−0.8 V) and internal compensation enable stable unity-gain operation without external components.
It features independent shutdown pins per pair (pins 5 and 10), enabling selective channel disablement while maintaining bias integrity across remaining active amplifiers - critical for power-managed multi-stage filters and programmable gain stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - supports stable closed-loop operation up to 10× gain at 1 MHz, suitable for anti-aliasing and reconstruction filters. |
| Output drive (IOH/IOL) | 57 mA sourcing / 55 mA sinking at VDD−1.5 V / 0.5 V - drives 600 Ω loads directly without external buffers in audio line outputs. |
| Slew rate (SR+/SR−) | 16 V/μs / 19 V/μs - enables <0.39 μs settling to 0.01% for 1 V step, meeting fast-settling DAC buffer requirements. |
| Input offset voltage | 60 μV typical (25°C), ≤2 mV max over full temperature range - preserves DC accuracy in 12-bit+ data acquisition systems. |
| Supply current per channel | 1.9 mA at 5 V, no load - allows four-channel operation within 8 mA total, fitting low-power portable instrumentation. |
| Shutdown current | 125 μA per channel - reduces system standby power by >93% versus active mode, enabling battery-backed sensor nodes. |
| Input noise voltage | 7 nV/√Hz at 1 kHz - maintains SNR >90 dB in microphone preamps and strain-gauge amplifiers with 10 kΩ source impedances. |
Pinout & Package
Package: 14-pin plastic DIP (N), 0.300-inch wide body, through-hole mounting compatible with standard PCB footprints and wave-solder processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 output | High-current output capable of ±57 mA; requires local 0.1 μF bypass capacitor to GND for stability. |
| 2 | Channel 1 inverting input | High-impedance CMOS node (1 TΩ typ); sensitive to PCB leakage - guard ring recommended in high-precision layouts. |
| 3 | Channel 1 non-inverting input | Matches pin 2 in offset and bias; used for unity-gain buffers or differential input stages with matched trace routing. |
| 4 | GND | Analog ground reference for all four channels; must connect to low-impedance ground plane with dedicated via. |
| 5 | Channel 1/2 shutdown | Active-high logic input; ≥2 V enables both A and B amplifiers, ≤0.8 V disables them with 125 μA quiescent draw. |
| 6 | VDD | Single positive supply (4.5–16 V); decoupling required within 1 cm of pin using 10 μF tantalum + 0.1 μF ceramic. |
| 7 | Channel 2 output | Independent output with identical drive specs as pin 1; supports dual-channel parallel drive for higher current. |
| 8 | Channel 2 inverting input | Electrically identical to pin 2; shares same input stage architecture and noise performance. |
| 9 | Channel 2 non-inverting input | Matches pin 3; enables dual-channel instrumentation configurations with shared reference paths. |
| 10 | Channel 3/4 shutdown | Separate control for C/D amplifiers; allows asymmetric power management (e.g., keep A/B active, sleep C/D). |
| 11 | Channel 3 non-inverting input | Third channel input; routed separately to avoid crosstalk coupling into sensitive measurement paths. |
| 12 | Channel 3 inverting input | Paired with pin 11; supports independent gain-setting resistors for multi-range sensor interfaces. |
| 13 | Channel 3 output | Third output with full 57 mA drive; usable for auxiliary functions like LED bias or reference buffer. |
| 14 | Channel 4 output | Fourth independent output; completes quad configuration for 4-wire RTD excitation or multi-axis motor control feedback. |

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), lower output drive (±10 mA), higher input offset (3 mV max), no shutdown function. | Acceptable for low-speed, low-current applications like basic active filters but unsuitable for audio line driving or fast-settling DAC buffers. | Select TL074CN only when cost is primary constraint and performance margins (bandwidth, drive, noise) are not design-critical. |
| OPA4134UA | Higher precision (50 μV offset, 0.1 μV/°C drift), lower noise (8 nV/√Hz), no shutdown, SO-14 package only. | Better for ultra-low-distortion audio and metrology, but lacks shutdown and PDIP packaging - incompatible with legacy through-hole designs. | Choose OPA4134UA for premium audio or lab-grade instrumentation where PDIP is not required and shutdown is unnecessary. |
Compared with TL074CN and OPA4134UA, the TLC074CN uniquely balances high output drive, 10 MHz bandwidth, shutdown control, and PDIP packaging - making it the only option that meets simultaneous requirements for legacy-compatible, power-managed, high-fidelity analog signal chains.

FAQ
What is the maximum supply voltage for the TLC074CN?
The absolute maximum supply voltage for the TLC074CN is 17 V, but the recommended operating range is 4.5 V to 16 V. Operation at 16 V enables full output swing (up to 14.5 V) and maximizes slew rate (19 V/μs negative), while staying safely within thermal limits for the 14-pin PDIP package. Exceeding 17 V risks permanent damage per TI's SLOS219F datasheet Absolute Maximum Ratings table.
Does the TLC074CN support rail-to-rail input operation?
The TLC074CN supports rail-to-rail input common-mode voltage from 0.5 V to VDD−0.8 V - meaning it accepts signals within 0.5 V of ground and 0.8 V below VDD. It does not support true rail-to-rail input (i.e., down to 0 V or up to VDD), but this range covers most single-supply sensor and audio applications. Input protection diodes clamp beyond these limits, so external limiting is required for overvoltage conditions.
How does the shutdown feature work on the TLC074CN?
The TLC074CN has two independent shutdown pins: pin 5 controls channels 1 and 2, and pin 10 controls channels 3 and 4. A logic-high signal ≥2 V enables the respective pair; ≤0.8 V disables them, reducing supply current to 125 μA per channel. The disabled amplifiers retain input bias integrity and recover in 0.47 μs (turn-on time at 12 V), enabling fast power cycling in battery-operated systems without signal disruption to other active channels.
Can the TLC074CN drive a 600 Ω load at 10 Vpp?
Yes - the TLC074CN delivers ±57 mA output current, enabling it to drive 600 Ω loads to ±10 Vpp (20 Vpp) at 5 V supply (VOH = 3.2 V, VOL = 0.7 V) and ±10.3 Vpp at 12 V supply (VOH = 10.3 V, VOL = 0.65 V). At 12 V, it sustains 10 Vpp into 600 Ω with <0.005% THD+N at 1 kHz, meeting professional audio line driver specifications without external buffering.
What is the input offset voltage specification for the TLC074CN over temperature?
The TLC074CN has a typical input offset voltage of 60 μV at 25°C, with a maximum of 2000 μV (2 mV) over the full −40°C to 125°C industrial temperature range. Its temperature coefficient is 1.2 μV/°C, meaning offset drift contributes ≤120 μV over a 100°C span. This performance exceeds legacy TL074 (10 mV max) and supports 12-bit accuracy in sensor interfaces without trimming.
