Product details

Overview

TLC075IN from Texas Instruments is a quad-channel, single-supply operational amplifier with 10 MHz gain-bandwidth product, ±57 mA high-output-drive capability, 16 V/μs positive slew rate, and ultralow 125 μA/channel shutdown current. It operates from 4.5 V to 16 V and delivers rail-to-rail output swing in industrial temperature range (−40°C to 125°C), making it suitable for precision analog front-ends in automotive sensor signal conditioning.

For engineers reviewing the TLC075IN datasheet, TLC075IN pinout, TLC075IN application, or TLC075IN equivalent, this page provides verified electrical parameters, package-specific terminal mapping, real-world use cases in sensor amplification and active filtering, and validated alternative parts with documented functional trade-offs.

Technical Context

The TLC075IN uses TI's LBC3 BiCMOS process to combine a low-noise CMOS input stage (7 nV/√Hz input voltage noise, 1000 GΩ differential input resistance) with a high-current bipolar output stage capable of sourcing/sinking ±55 mA. Its architecture supports stable unity-gain operation with 37° phase margin at 12 V supply and 50 pF capacitive load.

It features independent channel shutdown control via dedicated SHDN pins (pins 5 and 13), enabling dynamic power management in multi-stage analog chains. Input common-mode range extends from 0.5 V to VDD − 0.8 V, supporting direct interfacing with ADC reference voltages and microcontroller I/O without level-shifting.

Key Specifications

Gain-bandwidth product	10 MHz - Enables stable closed-loop operation up to 10× gain at 1 MHz, suitable for anti-aliasing filters and broadband instrumentation.
Output drive (IOH/IOL)	±57 mA / ±55 mA - Drives low-impedance loads (e.g., 600 Ω audio lines or 100 Ω transmission lines) without external buffers.
Slew rate (SR+/SR−)	16 V/μs / 19 V/μs - Supports fast transient response in pulse amplification and DAC output buffering with <0.39 μs settling time to 0.01%.
Input offset voltage (max)	3 mV over full temperature range - Ensures ≤0.3% DC error in 1 V full-scale sensor interfaces without trimming.
Supply current (per channel)	2.5 mA typical at 5 V - Enables four-channel operation within 10 mA total analog supply budget for portable systems.
Shutdown current (per channel)	250 μA max - Reduces quiescent power by >90% per channel during idle periods in battery-powered data loggers.
Input voltage noise	7 nV/√Hz at 1 kHz - Critical for low-level thermocouple or strain gauge amplification where noise dominates resolution.

Pinout & Package

Package: 16-pin plastic DIP (N) with through-hole mounting, 0.300-inch wide body, compatible with standard IC sockets and wave-solder processes.

Pin/Terminal	Circuit Role	Design Meaning
1	1OUT	Channel 1 output - Delivers amplified signal with ±55 mA drive strength; requires local 0.1 μF bypass capacitor to ground.
2	1IN−	Inverting input - High-impedance node (1000 GΩ); sensitive to PCB leakage; guard ring recommended for sub-mV accuracy.
3	1IN+	Non-inverting input - Common-mode range 0.5 V to VDD − 0.8 V; accepts direct connection to resistive sensor bridges.
4	VDD	Positive supply - Accepts 4.5–16 V; must be decoupled with ≥10 μF bulk + 0.1 μF ceramic capacitor near pin.
5	2IN+	Channel 2 non-inverting input - Electrically isolated from other channels; enables independent differential sensing per pair.
6	2IN−	Channel 2 inverting input - Matches pin 2 characteristics; supports matched feedback networks for dual-channel matched gain.
7	2OUT	Channel 2 output - Identical drive capability to pin 1; shares same thermal path on DIP package for consistent channel matching.
8	GND	Analog ground reference - Star-point connection required; separates from digital ground to avoid noise coupling into sensitive inputs.
9	3OUT	Channel 3 output - Enables three-stage signal chain (e.g., gain → filter → driver) without interposer boards.
10	3IN−	Channel 3 inverting input - Supports cascaded configurations; pin 10 layout symmetry minimizes parasitic capacitance mismatch vs pin 2.

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, 2.5 mA/channel supply current.	Lacks rail-to-rail output and thermal stability for automotive use; suitable only for cost-sensitive consumer audio where 125°C operation is unnecessary.	Choose TL074CN only if legacy design reuse is required and full industrial temp range is not needed.
OPA4134UA	Lower noise (8 nV/√Hz), higher precision (250 μV max VIO), but lower output drive (±10 mA) and no shutdown mode.	Better for ultra-low-noise audio preamps but cannot drive heavy loads; lacks power-gating capability for battery-powered instruments.	Select OPA4134UA when noise dominates performance and output loading is <5 mA; avoid when driving cables or ADC references.

Compared with TL074CN and OPA4134UA, the TLC075IN uniquely balances high-speed (10 MHz), high-drive (±55 mA), low-noise (7 nV/√Hz), and power-gating (250 μA shutdown) in a single quad package-enabling compact, thermally robust, and energy-efficient analog subsystems where multiple performance vectors matter simultaneously.

FAQ

What is the maximum operating temperature range for the TLC075IN?

The TLC075IN is rated for continuous operation from −40°C to 125°C, as confirmed in the Absolute Maximum Ratings table and Recommended Operating Conditions section of the SLOS219F datasheet. This industrial temperature grade makes it suitable for under-hood automotive applications and factory-floor industrial controllers where ambient temperatures exceed 85°C.

Does the TLC075IN support true rail-to-rail input operation?

No, the TLC075IN does not support rail-to-rail input. Its common-mode input voltage range is specified as 0.5 V to VDD − 0.8 V across the full temperature range. For example, at VDD = 12 V, valid input voltages span 0.5 V to 11.2 V - excluding the top 0.8 V and bottom 0.5 V of the supply rails.

How many independent shutdown controls does the TLC075IN provide?

The TLC075IN provides two independent shutdown controls: pin 5 (1/2SHDN) disables channels 1 and 2, while pin 12 (3/4SHDN) disables channels 3 and 4. Each control requires a logic-high voltage ≥2 V to enable and logic-low ≤0.8 V to enter shutdown mode, reducing per-channel supply current to ≤250 μA total for the pair.

What is the typical output voltage swing for the TLC075IN at 50 mA load current?

At VDD = 12 V and 50 mA load, the TLC075IN delivers VOH ≥10.3 V and VOL ≤0.65 V, per the Electrical Characteristics table on page 8 of SLOS219F. This represents a 11.65 V peak-to-peak swing - 97% of the 12 V rail span - confirming strong rail-swing capability even under heavy load.

Can the TLC075IN drive a 600 Ω load at 1 MHz without instability?

Yes, the TLC075IN maintains stability into 600 Ω loads at 1 MHz. Its 10 MHz gain-bandwidth product, combined with 37° phase margin at 12 V with 50 pF capacitive load (Figure 20), ensures robust closed-loop behavior. Application curves (Figures 31–32) confirm clean large-signal pulse response into 600 Ω at full bandwidth.
