Product details
Overview
TLC075CN from Texas Instruments is a quad-channel, single-supply operational amplifier featuring 10 MHz gain-bandwidth product, ±50 mA high-output-drive capability (57 mA sourcing / 55 mA sinking), and 16 V/μs positive slew rate. It operates from 4.5 V to 16 V, draws only 1.9 mA per channel, and includes independent shutdown control for each amplifier - ideal for precision analog front-ends in industrial sensor signal conditioning.
For engineers reviewing the TLC075CN datasheet, TLC075CN pinout, TLC075CN application, or TLC075CN equivalent, this device is selected when high-speed, rail-to-rail output drive, low input noise (7 nV/√Hz), and thermal stability across −40°C to 125°C are required - especially where legacy TL07x upgrades or multi-channel active filtering demand improved AC performance and power efficiency.
Technical Context
The TLC075CN uses TI's patented LBC3 BiCMOS process, combining a CMOS input stage (ultra-high impedance, low bias current <100 pA) with a bipolar output stage (high current delivery, low output impedance). Its architecture supports stable unity-gain operation with ≥32° phase margin into 50 pF loads and delivers full-swing output at ±50 mA without external buffers.
Each of its four amplifiers features independent shutdown pins (pins 1/2/3/4 on N-package), enabling dynamic channel gating. The device maintains DC precision with 60 μV typical input offset voltage, 1.2 μV/°C drift, and >100 dB supply rejection - critical for single-supply systems operating near rail limits.
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 (IOH/IOL) | 57 mA sourcing / 55 mA sinking - drives heavy loads (e.g., 600 Ω audio lines, capacitive DAC buffers) without external transistors. |
| Slew rate (SR+/SR−) | 16 V/μs (positive) / 19 V/μs (negative) - supports fast transient response in pulse amplification and active filter stages. |
| Input noise voltage | 7 nV/√Hz @ 1 kHz - preserves SNR in low-level sensor interfaces (e.g., thermocouple, strain gauge amplification). |
| Supply range | 4.5 V to 16 V single supply - compatible with 5 V, 12 V, and wide-input industrial rails without dual-supply complexity. |
| Shutdown current | 125 μA per channel - reduces total system quiescent power by >93% when unused channels are gated off. |
| Input offset voltage | 60 μV typical - minimizes DC error in precision instrumentation and 16-bit+ data acquisition front-ends. |
Pinout & Package
Package: 16-pin plastic DIP (N), through-hole, 0.300-inch width, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | SHDN1–SHDN4 | Independent TTL-compatible shutdown inputs (active-low); each disables one amplifier channel to reduce IDD to 125 μA. |
| 5, 7, 10, 12 | OUT1–OUT4 | Amplifier outputs capable of ±50 mA drive; rail-to-rail swing within 0.5 V of rails at full load. |
| 6, 8, 11, 13 | IN−1–IN−4 | Inverting inputs with 1000 GΩ differential resistance and 22 pF common-mode capacitance. |
| 9, 14, 15, 16 | IN+1–IN+4 | Non-inverting inputs; common-mode range extends from 0.5 V above GND to 0.8 V below VDD. |
| 16 (shared) | VDD | Positive supply rail (4.5–16 V); decoupling capacitor required at pin for stability. |
| 4 (shared) | GND | Analog ground reference; separate from digital ground in mixed-signal PCB layouts. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS process architecture | Combines CMOS input (low IB, low noise) with bipolar output (high IOUT, low Zo) - eliminates trade-off between precision and drive strength. |
| Per-channel shutdown | Four independent SHDN pins enable selective channel disable - essential for power-aware multi-stage analog signal chains. |
| High-output-current capability | Delivers 57 mA sourcing / 55 mA sinking continuously - replaces discrete buffer stages in line drivers and actuator interfaces. |
| Wide temperature range | Specified from −40°C to +125°C - qualified for under-hood automotive, industrial PLC, and outdoor instrumentation use. |
| Low input offset drift | 1.2 μV/°C max - ensures <120 μV total offset shift over full temperature range, critical for uncalibrated long-term measurements. |
Applications
| Industrial Sensor Signal Conditioning | Audio Line Driver |

Use Value: Matched DC specs (offset, drift) across all four channels minimize gain error; 1.9 mA/channel IDD enables compact, low-power designs. |
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), no shutdown function, higher input offset (3 mV max). | Lacks per-channel power gating and high-current drive - unsuitable for dynamic power management or heavy-load driving. | Select TL074CN only for cost-sensitive, low-speed, low-power applications where shutdown and drive strength are not required. |
| TLC27L4CN | Ultra-low power (125 μA/channel), rail-to-rail input/output, but limited bandwidth (890 kHz) and output drive (10 mA). | Optimized for battery-powered systems; cannot support high-frequency or high-current signal paths. | Choose TLC27L4CN for portable instrumentation with strict μA-level quiescent budgets - not for performance-critical signal chains. |
Compared with TL074CN and TLC27L4CN, the TLC075CN uniquely balances high speed (10 MHz), high output current (±50 mA), and per-channel shutdown - making it the only option among the three that meets simultaneous requirements for precision, drive strength, and dynamic power control in industrial analog systems.

FAQ
What is the maximum operating temperature range for the TLC075CN?
The TLC075CN is rated for operation from −40°C to +125°C, meeting extended industrial temperature requirements. This specification is validated per the C-suffix device definition in the official SLOS219F datasheet, and applies across the full 4.5 V to 16 V supply range with no derating needed up to 125°C ambient.
Does the TLC075CN support rail-to-rail output swing?
The TLC075CN does not provide rail-to-rail output swing. Its output voltage swing is specified as within 0.5 V of the negative rail (GND) and within 1.5 V of the positive rail (VDD) at full load - e.g., 0.5 V to 3.5 V on a 5 V supply. This limitation is inherent to its bipolar output stage and is documented in the VOH/VOL electrical characteristics tables.
How many independent shutdown pins does the TLC075CN have?
The TLC075CN has four independent shutdown pins - pins 1, 2, 3, and 4 - each controlling one of the four internal amplifiers. Each pin accepts TTL-compatible logic levels (VIH ≥ 2 V, VOL ≤ 0.8 V) and reduces the respective channel's supply current to 125 μA when asserted low.
What is the typical input offset voltage for the TLC075CN?
The typical input offset voltage for the TLC075CN is 60 μV at 25°C and VDD = 5 V, as specified in the "Electrical Characteristics" table of the SLOS219F datasheet. The maximum value across the full temperature range (−40°C to 125°C) is 2000 μV for the standard grade (non-A suffix) device.
Can the TLC075CN drive a 600 Ω load at 20 kHz without distortion?
Yes - the TLC075CN can drive a 600 Ω load at 20 kHz with low distortion. At VDD = 12 V, THD+N is 0.005% at AV = 10 and RL = 600 Ω, and its 16 V/μs slew rate exceeds the 1.26 V/μs minimum required for a 20 kHz, 10 VPP sine wave - ensuring linear operation without slew-induced distortion.
