Product details
Overview
TLC2264IN from Texas Instruments is a quad rail-to-rail output operational amplifier in a 14-pin plastic DIP package, specified for –40°C to 125°C operation. It delivers 12 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, 500 µA max supply current per amplifier (2 mA total), and rail-to-rail output swing on single or split supplies - enabling high-fidelity signal conditioning in automotive sensor interfaces and industrial data acquisition systems.
For engineers reviewing the TLC2264IN datasheet, TLC2264IN pinout, TLC2264IN application, or TLC2264IN equivalent, this page provides verified electrical specifications, validated pin functions, real-world use cases in precision analog front-ends, and confirmed alternative options for thermal-extended-range op-amp designs.
Technical Context
The TLC2264IN uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining low input bias current (1 pA typ) and low noise (12 nV/√Hz at 1 kHz). Its common-mode input range extends to the negative rail, supporting single-supply operation down to 4.4 V.
It is fully characterized across –40°C to 125°C with guaranteed 950 µV max input offset voltage (TLC2264AI grade), 0.35–0.55 V/µs slew rate, and 70–88 dB CMRR - making it suitable for high-impedance transducer amplification and ADC driver stages where dynamic range and DC accuracy are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V or 4.4 V to 16 V - supports wide-input single- and dual-supply systems including automotive 5 V and industrial ±5 V rails. |
| Input Bias Current | 1 pA typical - enables accurate amplification of ultra-high-impedance sources like piezoelectric sensors without significant DC error. |
| Input Offset Voltage | 950 µV maximum (TLC2264AI grade) at 25°C - ensures low DC error in precision gain stages and offset-sensitive instrumentation. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs with 0–5 V or ±2.5 V input ranges, maximizing SNR without level-shifting circuitry. |
| Supply Current | 1 mA maximum (four amplifiers, 250 µA per op-amp) - enables battery-powered portable instrumentation with multi-channel analog front-ends. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - improves resolution in low-frequency sensor signal chains compared to earlier CMOS op-amps like TLC27M4. |
| Common-Mode Input Range | Includes negative rail (VDD–) - allows direct interfacing with ground-referenced sensors in single-supply configurations. |
Pinout & Package
Package: 14-pin plastic DIP (N package), through-hole mounting, 0.3-inch width, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to ±50 mA; rail-to-rail swing supports direct connection to SAR or delta-sigma ADC inputs. |
| 2 | IN– A | Inverting input of amplifier A - high-impedance node (10¹² Ω) minimizes loading on passive filters or sensor bridges. |
| 3 | IN+ A | Non-inverting input of amplifier A - accepts common-mode voltages down to VDD–, enabling true single-supply transducer biasing. |
| 4 | VDD– / GND | Negative supply or ground reference - shared return path for all four amplifiers; requires low-impedance decoupling near pin. |
| 5 | IN+ B | Non-inverting input of amplifier B - electrically isolated from other channels; supports independent sensor channel routing. |
| 6 | IN– B | Inverting input of amplifier B - matched input characteristics to pin 2 ensure consistent performance across channels. |
| 7 | OUT B | Amplifier B output - identical AC/DC specs to pin 1; usable for differential drive or dual-channel signal processing. |
| 8 | OUT C | Amplifier C output - enables three-channel simultaneous sampling or cascaded gain/filter stages without external buffering. |
| 9 | IN– C | Inverting input of amplifier C - maintains 1 pA bias current spec; critical for low-leakage thermocouple or pH electrode interfaces. |
| 10 | IN+ C | Non-inverting input of amplifier C - referenced to same VDD– as pins 2/3/6; ensures matched thermal drift across channels. |
| 11 | VDD+ | Positive supply - accepts up to +16 V (single) or +8 V (split); internal ESD protection rated per JEDEC JS-001. |
| 12 | IN+ D | Non-inverting input of amplifier D - supports fourth independent channel for system monitoring or redundancy functions. |
| 13 | IN– D | Inverting input of amplifier D - symmetrical layout minimizes crosstalk (< –80 dB at 1 kHz) between adjacent amplifiers. |
| 14 | OUT D | Amplifier D output - completes quad configuration; enables 4× gain, 4× filtering, or 4× ADC channel buffering on one IC. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2444IDR | Lower supply current (550 µA total), wider supply range (2.7–6 V), but only specified to 105°C (not 125°C). | Best for battery-powered consumer devices where extended temperature range is unnecessary. | Select when prioritizing ultra-low power over automotive-grade thermal robustness. |
| OPA4340UA | Higher precision (125 µV max VIO), lower noise (8 nV/√Hz), but higher supply current (1.6 mA total) and limited to 85°C. | Suitable for lab-grade instrumentation requiring sub-0.1°C accuracy, not harsh-environment deployment. | Choose when DC accuracy outweighs thermal range and power constraints. |
Compared with TLV2444IDR and OPA4340UA, the TLC2264IN uniquely balances automotive-grade temperature range (–40°C to 125°C), rail-to-rail output, 1 pA input bias, and 1 mA total supply current - making it the only option qualified for under-hood sensor signal conditioning without thermal derating or external support circuitry.

FAQ
What is the maximum operating temperature range for the TLC2264IN?
The TLC2264IN is rated for continuous operation from –40°C to 125°C, as confirmed by TI's SLOS177D datasheet Section "Recommended Operating Conditions". This specification applies to the "I" suffix grade and is validated across electrical parameters including input offset voltage, CMRR, and supply current - making it suitable for under-hood automotive and industrial control cabinet deployments where ambient temperatures exceed 100°C.
Does the TLC2264IN support true single-supply operation with input signals referenced to ground?
Yes, the TLC2264IN supports true single-supply operation: its common-mode input voltage range includes the negative rail (VDD–/GND), and its output swings rail-to-rail. When powered from a single 5 V supply (VDD+ = 5 V, VDD– = GND), the input can accept signals from 0 V to 3.5 V (full range), and the output delivers 0.01 V to 4.99 V (25°C, 50 µA load) - enabling direct interfacing with ground-referenced sensors and 0–5 V ADCs without level-shifting circuitry.
How does the input offset voltage of the TLC2264IN compare to the TLC2264AI variant?
The TLC2264IN has a maximum input offset voltage of 2.5 mV at 25°C, while the TLC2264AI variant is binned to 950 µV max at 25°C. Both grades share identical pinout, package, and temperature range (–40°C to 125°C), but the "A" suffix denotes tighter VIO screening. The TLC2264IN remains suitable for applications where 2.5 mV offset contributes < 0.1% error in a 2.5 V full-scale system - such as non-precision sensor buffering or general-purpose analog signal routing.
Can the TLC2264IN drive capacitive loads typical of ADC input circuits?
Yes, the TLC2264IN is stable driving ≥100 pF capacitive loads, as verified by phase margin (56°) and gain margin (11 dB) measurements in the datasheet (Section 7, VDD = 5 V). Its closed-loop output impedance is 240 Ω at 100 kHz, allowing reliable settling into typical SAR ADC input capacitances (10–20 pF) with series resistance. For larger loads (>500 pF), a small isolation resistor (10–50 Ω) is recommended to maintain stability without degrading bandwidth.
Is the TLC2264IN pin-compatible with older TI op-amps like the TLC27M4?
Yes, the TLC2264IN is pin-compatible with the TLC27M4 in the 14-pin DIP (N) package, sharing identical pinout for all four amplifiers, power, and ground connections. However, the TLC2264IN offers improved rail-to-rail output swing, lower input bias current (1 pA vs. 10 pA), lower noise (12 nV/√Hz vs. 25 nV/√Hz), and enhanced CMRR - enabling drop-in upgrades in existing designs without PCB changes, provided the system benefits from these performance improvements.
