Product details

Overview

TLC074ID from Texas Instruments is a quad-channel, single-supply operational amplifier with 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, features ultralow 125 μA/channel shutdown current, and delivers 7 nV/√Hz input voltage noise - optimized for precision audio buffering, industrial sensor signal conditioning, and high-current analog output stages.

For engineers reviewing the TLC074ID datasheet, TLC074ID pinout, TLC074ID application, or TLC074ID equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options for design-in and supply continuity planning.

Technical Context

The TLC074ID employs TI's patented LBC3 BiCMOS process, integrating a high-impedance CMOS front end for low input bias (≤700 pA) and low noise with a bipolar output stage enabling ±57 mA drive into heavy loads. Its rail-to-rail input common-mode range (0.5 V to VDD−0.8 V) and fast turn-on time (0.47 μs at VDD = 12 V) support dynamic single-supply systems.

It includes independent channel-level shutdown control (pins 5 and 10), supports stable operation with capacitive loads up to 100 pF (phase margin ≥37°), and maintains 10 MHz bandwidth across −40°C to +125°C - making it suitable for automotive body electronics and industrial PLC analog I/O modules where thermal robustness and load-driving fidelity are critical.

Key Specifications

Pinout & Package

Package: SOIC-14 (D package), 8.65 mm × 3.91 mm, surface-mount, RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1	Channel 1 Output	Amplified output of first op-amp; capable of ±57 mA drive into resistive or capacitive loads.
2	Channel 1 Inverting Input	Inverting node for configuring gain, filtering, or summing; high impedance (≥1 TΩ) minimizes loading on preceding stages.
3	Channel 1 Non-Inverting Input	Non-inverting input; supports rail-to-rail common-mode range (0.5 V to VDD−0.8 V) for full dynamic range utilization.
4	Ground	Analog ground reference for all four channels; must be low-impedance and separated from digital ground in mixed-signal PCBs.
5	Channel 1 Shutdown	Active-high logic control (VIH ≥2 V); disables Channel 1 output and reduces its IDD to 125 μA - enables selective channel power gating.
6	Channel 2 Non-Inverting Input	Non-inverting input for second op-amp; electrically isolated from other channels to prevent crosstalk (<−120 dB at 10 kHz).
7	Channel 2 Inverting Input	Inverting input for second op-amp; matched offset and bias characteristics ensure consistent performance across all four channels.
8	Channel 2 Output	Second independent output; identical drive strength and noise specs as Pin 1 - supports dual-path signal processing.
9	VDD	Positive supply rail (4.5–16 V); powers all four op-amps and internal bias circuitry; requires local 0.1 μF ceramic decoupling.
10	Channel 2 Shutdown	Independent active-high shutdown for Channel 2 - allows asymmetric power management (e.g., keep Ch1/Ch3 active while disabling Ch2/Ch4).
11	Channel 3 Inverting Input	Inverting input for third op-amp; pin-compatible layout with standard quad op-amp footprints for drop-in replacement flexibility.
12	Channel 3 Non-Inverting Input	Non-inverting input for third op-amp; supports same input voltage range and noise performance as Pins 2 and 3.
13	Channel 4 Inverting Input	Inverting input for fourth op-amp; fully characterized for matching (ΔVIO ≤300 μV between channels) in precision multi-channel designs.
14	Channel 4 Output	Fourth output; delivers full ±57 mA drive and 16 V/μs slew rate - suitable for driving ADC reference buffers or DAC output stages.

Key Features

Feature	Design Value
BiMOS Process Architecture	Combines CMOS input stage (low IB, low noise) with bipolar output stage (high drive, low Zo) - eliminates trade-off between precision and power delivery.
Independent Channel Shutdown	Pins 5 and 10 enable per-channel disable - reduces system-level power by >90% in idle channels without affecting active signal paths.
Rail-to-Rail Input Common-Mode Range	Operates with inputs as low as 0.5 V above GND and as high as VDD−0.8 V - maximizes usable input swing in single-supply data acquisition.
High Output Current Capability	±57 mA continuous output - drives low-impedance loads (e.g., 600 Ω audio lines, relay coils, LED strings) without external transistors.
Low Input Offset Voltage Drift	1.2 μV/°C max - ensures stable DC accuracy over temperature in closed-loop sensor interfaces and precision integrators.
Stable with Capacitive Loads	Maintains ≥37° phase margin with up to 100 pF load capacitance - simplifies layout for long traces or LCD bias networks without external compensation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TL074CDR	Lower bandwidth (3 MHz), higher input offset (10 mV max), no shutdown pins, 2.5 mA/channel supply current.	Lacks per-channel shutdown and high-output drive; suited only for low-speed, low-precision legacy designs.	Select TL074CDR only if cost sensitivity outweighs performance needs and thermal range is limited to 0°C–70°C.
OPA4134UA	Lower noise (4.5 nV/√Hz), lower supply current (4 mA/ch), no shutdown, ±13 V max supply, SOIC-14 package.	Superior audio SNR but lacks high-current drive and shutdown - unsuitable for actuator or loop-powered outputs.	Choose OPA4134UA for ultra-low-noise audio preamps where output load is >10 kΩ and power budget permits higher IDD.

Compared with TLC074ID, TL074CDR trades bandwidth, drive, and temperature range for lower cost, while OPA4134UA prioritizes noise and linearity over output strength and power management - making TLC074ID uniquely balanced for high-fidelity, high-drive, thermally demanding analog systems.

FAQ

What is the maximum output current specification for TLC074ID?

The TLC074ID delivers ±57 mA sourcing current (IOH) at VDD − 1.5 V and ±55 mA sinking current (IOL) at 0.5 V above GND, verified across −40°C to +125°C. This enables direct drive of 600 Ω audio loads, relay coils, and LED arrays without external transistors - a key differentiator versus standard rail-to-rail op-amps.

Does TLC074ID support true rail-to-rail input operation?

Yes, the TLC074ID supports a common-mode input voltage range from 0.5 V to VDD − 0.8 V, allowing signals within 0.5 V of GND and within 0.8 V of VDD to be accurately amplified. This near rail-to-rail input capability maximizes dynamic range in single-supply systems such as battery-powered data loggers and automotive sensors.

How many independent shutdown controls does TLC074ID provide?

The TLC074ID provides two independent active-high shutdown pins: Pin 5 controls Channel 1, and Pin 10 controls Channel 2. Channels 3 and 4 do not have dedicated shutdown - they remain active whenever VDD is applied. This architecture enables partial power-down in multi-channel systems while preserving critical signal paths.

What is the typical input offset voltage for TLC074ID at 25°C and full temperature range?

At 25°C, the TLC074ID has a typical input offset voltage of 390 μV (max 1400 μV for A-grade). Over the full −40°C to +125°C range, the maximum offset is 2000 μV for A-grade and 3000 μV for standard grade - specified under VDD = 5 V or 12 V with VIC = VDD/2 and RL = 50 Ω.

Can TLC074ID operate stably with capacitive loads, and what is the maximum supported value?

Yes, the TLC074ID maintains stability with capacitive loads up to 100 pF, demonstrated by ≥37° phase margin at VDD = 12 V and RL = 10 kΩ. This allows direct connection to long PCB traces, LCD bias networks, or piezoelectric transducers without external isolation resistors or compensation networks.

What package type is used for TLC074ID, and is it RoHS-compliant?

The TLC074ID is supplied in a 14-pin SOIC (D) package measuring 8.65 mm × 3.91 mm, with standard 1.27 mm lead pitch. It is RoHS-compliant and halogen-free, meeting IPC/JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) for standard reflow assembly.
