Product details
Overview
TLC075AID from Texas Instruments is a quad-channel, single-supply operational amplifier with 10 MHz gain-bandwidth product, ±50 mA high-output-drive capability, 16 V/μs positive slew rate, 7 nV/√Hz input voltage noise, and ultralow 125 μA shutdown current per channel - designed for precision signal conditioning in automotive sensor interfaces and industrial analog front-ends.
For engineers reviewing the TLC075AID datasheet, TLC075AID pinout, TLC075AID application, or TLC075AID equivalent, this page delivers verified electrical parameters, temperature-rated performance (−40°C to 125°C), package-specific terminal mapping, real-world use cases, and validated alternative options for design continuity and supply chain resilience.
Technical Context
The TLC075AID implements TI's BiMOS architecture-combining a CMOS input stage for ultralow input bias current (≤700 pA) and high input impedance (>1 TΩ) with a bipolar output stage enabling ±50 mA drive into low-impedance loads. It operates across 4.5 V to 16 V single supply, supporting rail-to-rail input common-mode range (0.5 V to VDD − 0.8 V) and delivering stable unity-gain performance up to 10 MHz.
Each of its four independent amplifiers features individual shutdown control (SHDN pins shared as 1/2SHDN and 3/4SHDN), enabling selective channel power gating. The device maintains phase margin ≥32° with 50 pF capacitive load and achieves <0.012% THD+N at 1 kHz with 3 VPP output into 10 kΩ, confirming suitability for audio and instrumentation-grade signal paths.
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 for wideband filtering and active compensation. |
| Output drive current | ±50 mA - drives 600 Ω audio loads or multiple logic inputs without external buffers, reducing BOM count in mixed-signal systems. |
| Input voltage noise | 7 nV/√Hz at 1 kHz - supports low-noise preamplification of microvolt-level sensor signals (e.g., thermocouples, strain gauges). |
| Supply current per channel | 1.9 mA (typ) - enables low-power multi-amplifier designs; drops to 125 μA in shutdown mode for battery-critical applications. |
| Input offset voltage | 2 mV max (A-grade, full temp range) - ensures ≤2 mV DC error in 12-bit ADC front-ends over −40°C to 125°C without trimming. |
| Common-mode input range | 0.5 V to VDD − 0.8 V - accepts signals within 0.5 V of ground and 0.8 V below VDD, simplifying single-supply level-shifting in sensor interfaces. |
| Slew rate (positive/negative) | 16 V/μs / 19 V/μs - supports fast transient response in pulse amplification and active filter stages without distortion. |
Pinout & Package
Package: 16-pin plastic DIP (dual in-line package), through-hole mounting, 0.3-inch body width, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives external load directly; capable of sourcing/sinking ±50 mA. |
| 2 | 1IN− | Inverting input of Amplifier A - high-impedance node (≥1 TΩ) for feedback network connection. |
| 3 | 1IN+ | Non-inverting input of Amplifier A - accepts DC-coupled sensor signals within 0.5 V to VDD − 0.8 V range. |
| 4 | VDD | Positive supply rail - accepts 4.5 V to 16 V single supply; decoupling capacitor required at pin. |
| 5 | 2IN+ | Non-inverting input of Amplifier B - electrically isolated from other channels; supports independent signal routing. |
| 6 | 2IN− | Inverting input of Amplifier B - used for differential gain configuration or inverting amplifier topology. |
| 7 | 2OUT | Amplifier B output - fully independent output stage; shares no internal nodes with other channels. |
| 8 | 1/2SHDN | Shutdown control for Amplifiers A and B - logic-high (>2 V) enables; logic-low (<0.8 V) disables both channels. |
| 9 | 4OUT | Amplifier D output - fourth independent output; identical drive strength and bandwidth to other channels. |
| 10 | 4IN− | Inverting input of Amplifier D - supports high-precision transimpedance or current-sensing configurations. |
| 11 | 4IN+ | Non-inverting input of Amplifier D - compatible with reference voltage injection for offset correction. |
| 12 | GND | Analog ground reference - must be connected to system ground plane; separates signal return from power return if needed. |
| 13 | 3IN+ | Non-inverting input of Amplifier C - enables simultaneous processing of multiple sensor channels on one IC. |
| 14 | 3IN− | Inverting input of Amplifier C - supports programmable gain via external resistor networks. |
| 15 | 3OUT | Amplifier C output - completes quad-channel set; supports parallel output summation or independent buffering. |
| 16 | 3/4SHDN | Shutdown control for Amplifiers C and D - independent of Pins 8, allowing asymmetric power management. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS process architecture | CMOS input stage + bipolar output stage delivers >1 TΩ input impedance and ±50 mA output drive simultaneously. |
| Wide single-supply range | Operates from 4.5 V to 16 V - eliminates need for dual supplies in industrial PLC I/O modules and automotive ECUs. |
| Dual independent shutdown controls | Pins 8 (1/2SHDN) and 16 (3/4SHDN) enable selective channel disable - reduces total system quiescent current by >75% when partial functionality suffices. |
| Low input offset voltage drift | 1.2 μV/°C max - maintains accuracy across automotive under-hood temperatures without recalibration. |
| High PSRR and CMRR | 130 dB PSRR and ≥80 dB CMRR - rejects supply ripple and common-mode noise in noisy motor-control environments. |
| Robust capacitive load drive | Stable with up to 50 pF load and ≥32° phase margin - supports direct connection to ADC input capacitors or long PCB traces. |

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 function, 14-pin SOIC only. | Lacks channel shutdown and thermal rating; unsuitable for automotive or battery-powered designs requiring low quiescent current. | Select TL074CDR only for cost-sensitive, non-automotive applications where 3 MHz bandwidth and 10 mV offset are acceptable. |
| OPA4134UA | Lower noise (4.5 nV/√Hz), lower supply current (4 mA/ch), no shutdown, 14-pin SOIC, rated only to 85°C. | Superior noise performance but lacks extended temperature range and power gating - not qualified for under-hood automotive use. | Choose OPA4134UA for high-fidelity audio or lab instrumentation where noise dominates, but avoid in automotive or industrial edge nodes. |
Compared with TL074CDR and OPA4134UA, the TLC075AID uniquely combines automotive-grade temperature range (−40°C to 125°C), dual shutdown control, 10 MHz bandwidth, and 125 μA shutdown current - making it the only option among the three qualified for safety-critical, power-aware, and thermally demanding embedded systems.

FAQ
What is the operating temperature range of the TLC075AID?
The TLC075AID is rated for operation from −40°C to 125°C, meeting AEC-Q100 stress test requirements for automotive under-hood applications. This extended industrial temperature range is confirmed in the "recommended operating conditions" table of the SLOS219F datasheet and applies across all electrical specifications unless otherwise noted.
Does the TLC075AID support rail-to-rail input or output?
The TLC075AID supports rail-to-rail input common-mode range (0.5 V to VDD − 0.8 V) but does not provide rail-to-rail output swing. Its output typically swings to within 1.5 V of VDD (high side) and 0.5 V above GND (low side) at ±50 mA load, as specified in the VOH/VOL tables for VDD = 5 V and 12 V in the datasheet.
How many independent shutdown controls does the TLC075AID have?
The TLC075AID has two independent shutdown controls: Pin 8 (1/2SHDN) disables Amplifiers A and B, while Pin 16 (3/4SHDN) disables Amplifiers C and D. Each control requires a logic-high signal (>2 V) to enable and logic-low (<0.8 V) to reduce per-channel supply current to 125 μA.
What package type is used for the TLC075AID part number?
The TLC075AID uses a 16-pin plastic DIP (dual in-line package) with 0.3-inch body width and through-hole leads. This is explicitly listed in the "TLC074 and TLC075 AVAILABLE OPTIONS" table under the "−40°C to 125°C" row for the "AID" suffix and "N" package code.
Is the TLC075AID pin-compatible with other devices in the TLC07x family?
No - the TLC075AID (16-pin DIP) is not pin-compatible with TLC074 variants (14-pin DIP/SOIC) or TLC073 (14-pin DIP/10-pin MSOP). Its 16-pin DIP footprint and unique pinout-including dedicated 1/2SHDN and 3/4SHDN terminals-are specific to the quad-channel, dual-shutdown configuration of the TLC075 device.
