Texas Instruments TLC074CD

Overview

TLC074CD from Texas Instruments is a quad-channel, single-supply operational amplifier in the BiMOS family, delivering 10 MHz gain-bandwidth, ±57 mA high-output drive, 16 V/μs positive slew rate, and 7 nV/√Hz input voltage noise - deployed in audio line drivers, industrial sensor signal conditioning, and active filter stages operating from 4.5 V to 16 V.

For engineers reviewing the TLC074CD datasheet, TLC074CD pinout, TLC074CD application, or TLC074CD equivalent, this page provides verified package mapping (SOIC-14), confirmed shutdown control logic, real-world output drive capability at 5 V/12 V, and validated alternatives for multi-channel rail-to-rail–compatible upgrades.

Technical Context

The TLC074CD integrates a CMOS front end for ultralow input bias current (≤100 pA) and high input impedance with a bipolar output stage enabling ±57 mA sourcing/sinking. Its 10 MHz unity-gain bandwidth and 19 V/μs negative slew rate support fast settling in active filters and buffer applications.

It features independent channel-level shutdown pins (pins 5 and 10), operates across 0°C to 70°C, and maintains stable phase margin (>32°) into 50 pF loads - critical for driving capacitive cables or ADC input networks without oscillation.

FAQ

What is the maximum output current capability of the TLC074CD?

The TLC074CD delivers ±57 mA sourcing current (IOH) at VDD − 1.5 V and ±55 mA sinking current (IOL) at 0.5 V, measured per channel under 25°C conditions. This enables direct drive of 600 Ω audio lines, relay coils, or LED arrays without external boost stages - a key differentiator versus legacy quad op-amps like TL074CD.

Does the TLC074CD support rail-to-rail input or output operation?

The TLC074CD supports rail-to-rail input common-mode range (VICR = 0.5 V to VDD − 0.8 V) but does not provide rail-to-rail output swing. Its output swings to within 1.5 V of VDD (high side) and 0.5 V above GND (low side) under 50 mA load. For true rail-to-rail output, consider alternatives like OPA4340, but note they lack the TLC074CD's 10 MHz bandwidth and ±57 mA drive.

How many independent shutdown controls does the TLC074CD have, and how do they operate?

The TLC074CD has two independent shutdown pins: pin 5 (1SHDN) for channels A/B and pin 10 (2SHDN) for channels C/D - each controlling two amplifiers. A logic-high voltage ≥2 V enables the associated pair; a logic-low ≤0.8 V disables them, reducing per-channel supply current to 125 μA. This allows selective power gating in multi-stage designs without disabling all four channels.

What is the typical input offset voltage for the TLC074CD, and how does it vary with temperature?

The TLC074CD has a typical input offset voltage of 390 μV at 25°C, with a maximum of 3000 μV across the full 0°C to 70°C range. Its temperature coefficient is 1.2 μV/°C, meaning offset drift remains tightly bounded - critical for DC-coupled sensor amplifiers where thermal stability directly impacts measurement accuracy over ambient variations.

Can the TLC074CD drive capacitive loads, and what is its phase margin with 50 pF?

Yes, the TLC074CD is designed to drive moderate capacitive loads. With a 10 kΩ load and 50 pF capacitance, its phase margin is ≥32° at 25°C (VDD = 5 V) and ≥37° (VDD = 12 V), ensuring stable closed-loop operation without added series isolation resistors - a key advantage over many general-purpose op-amps that oscillate under similar conditions.
