Product details
Overview
TLC2264AID from Texas Instruments is a quad rail-to-rail output operational amplifier in SOIC-14 package, designed for precision signal conditioning in single- or split-supply systems. It delivers 950 µV max input offset voltage at 25°C, 12 nV/√Hz input voltage noise at 1 kHz, 500 µA max supply current per amplifier, and full rail-to-rail output swing - enabling direct interfacing with 5-V or ±5-V ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLC2264AID datasheet, TLC2264AID pinout, TLC2264AID application, or TLC2264AID equivalent, this page provides verified pin functions, temperature-rated performance (–40°C to 125°C), low-noise design context for high-impedance sources, and validated alternatives for industrial analog signal chains requiring stable offset and CMOS input bias.
Technical Context
The TLC2264AID uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining ultra-low input bias current (1 pA typ) and low noise - critical for piezoelectric transducer amplification and remote sensor nodes. Its common-mode input range includes the negative rail, supporting single-supply operation down to 0 V reference.
It operates across ±2.2 V to ±8 V dual supplies or 4.4 V to 16 V single supply, with guaranteed performance over –40°C to 125°C. The device exhibits 0.35–0.55 V/µs slew rate, 0.71 MHz gain-bandwidth product, and 70–83 dB CMRR - balancing micropower efficiency and ac fidelity for medium-speed precision applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2264AIN | Same electrical specs but in PDIP-14 package; wider body, through-hole mount; no thermal pad; higher parasitic capacitance | Suitable for prototyping, legacy through-hole boards, or high-vibration environments where solder joint reliability is prioritized | Select TLC2264AIN only when through-hole assembly or manual rework is required; SOIC-14 (TLC2264AID) offers better high-frequency stability and smaller footprint |
| TLV2444CDR | Lower supply current (220 µA/amp), higher GBW (1.8 MHz), but 2.5 mV max VIO and only rated to 105°C | Better for high-speed, low-power battery apps where offset tolerance >2 mV is acceptable and ambient stays below 105°C | Choose TLV2444CDR for cost-sensitive consumer electronics; TLC2264AID remains preferred for industrial/automotive where 950 µV offset and 125°C operation are mandatory |
Compared with TLC2264AIN and TLV2444CDR, the TLC2264AID uniquely combines automotive-grade temperature range, sub-millivolt offset, and SOIC-14 manufacturability - making it the only option among the three qualified for AEC-Q100-compliant engine control and braking system signal chains.

FAQ
What is the maximum operating temperature for the TLC2264AID?
The TLC2264AID is fully specified from –40°C to +125°C ambient temperature. This extended range is confirmed in the "Recommended Operating Conditions" table of the SLOS177D datasheet and qualifies the device for under-hood automotive applications and industrial control cabinets exposed to high thermal stress. All key parameters - including input offset voltage, supply current, and output swing - are guaranteed across this full range.
Does the TLC2264AID support single-supply operation?
Yes, the TLC2264AID supports true single-supply operation from 4.4 V to 16 V. Its common-mode input voltage range extends to the negative rail (GND), and its rail-to-rail output swings within 10 mV of both supply rails - enabling direct interface with 5-V microcontrollers and ADCs without level-shifting circuitry. This is explicitly verified in the "Recommended Operating Conditions" and "Electrical Characteristics" sections for VDD = 5 V.
What is the input offset voltage specification for the TLC2264AID?
The TLC2264AID has a maximum input offset voltage of 950 µV at TA = 25°C, and 1500 µV over the full –40°C to +125°C operating range. This tighter offset spec distinguishes the "A" grade (TLC2264AID) from the standard TLC2264ID (2.5 mV max), making it suitable for precision DC-coupled applications such as bridge sensor amplification and medical biopotential measurement where calibration overhead must be minimized.
How does the noise performance of the TLC2264AID compare to earlier TI CMOS op-amps?
The TLC2264AID delivers 12 nV/√Hz input voltage noise at 1 kHz - a significant improvement over the TLC27M4 (30 nV/√Hz) and TS27M4 (35 nV/√Hz). This 2.5× noise reduction is achieved via optimized LinCMOS™ transistor sizing and biasing, directly enabling higher-resolution measurements in sensor front-ends. The 0.1–10 Hz peak-to-peak noise is also specified at 1.3 µV, confirming low-frequency stability for DC-coupled applications.
Is the TLC2264AID pin-compatible with the TLC2264CD or TLC2264CN?
Yes, the TLC2264AID is pin-compatible with TLC2264CD (SOIC-14, commercial temp) and TLC2264CN (PDIP-14, commercial temp) - all share identical 14-pin functional mapping and SOIC/PDIP footprints. However, the "A" grade offset and "I" grade temperature rating are exclusive to the TLC2264AID and TLC2264AIN variants. Electrical behavior outside the commercial range (e.g., at 125°C) is not guaranteed for non-"I" parts.
