Product details
Overview
TLC2272AID from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for precision, low-noise signal conditioning in single- or split-supply systems. It delivers 2.2-MHz gain-bandwidth, 3.6-V/µs slew rate, 9 nV/√Hz input voltage noise at 1 kHz, ≤950 µV input offset voltage (max), and 1-pA typical input bias current - enabling high-fidelity sensor interfacing in battery-powered handheld monitoring equipment.
For engineers reviewing the TLC2272AID datasheet, TLC2272AID pinout, TLC2272AID application, or TLC2272AID equivalent, key selection considerations include rail-to-rail output swing (±4.91 V at ±5 V supply), common-mode input range extending to negative rail, low 2.4–3 mA supply current, and SOIC-8 packaging suitable for space-constrained analog front-ends.
Technical Context
The TLC2272AID employs Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise - critical for driving high-impedance sources like piezoelectric transducers without signal degradation. Its input stage supports common-mode voltages down to VDD−, enabling direct connection to ground-referenced sensors in single-supply configurations.
It operates across ±2.2 V to ±8 V supply ranges (dual) or 4.4 V to 16 V (single), with full characterization at ±5 V and 5 V. The device exhibits 75–80 dB CMRR and 80–95 dB PSRR, ensuring stable performance under supply and common-mode variations in industrial sensing and ADC interface applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2.25 MHz - enables stable unity-gain buffering and closed-loop amplification up to ~200 kHz with 10× gain. |
| Slew rate | 3.6 V/µs typical - supports clean 20-kHz sine-wave output at ±2.3 V swing without distortion. |
| Input offset voltage | ≤950 µV max at TA = 25°C - reduces DC error in precision instrumentation and sensor offset correction circuits. |
| Input bias current | 1 pA typical - preserves signal integrity when amplifying from ultra-high-impedance sources (>1 GΩ). |
| Input voltage noise | 9 nV/√Hz at 1 kHz - 2× lower than legacy TLC27x op-amps, improving SNR in low-level analog signal chains. |
| Supply current per channel | 2.4–3 mA - enables dual-channel operation in micropower systems with <6 mA total quiescent draw. |
| Output voltage swing | ±4.91 V at ±5 V supply with 500 µA load - delivers >98% of rail-to-rail dynamic range for maximum ADC utilization. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432IDR | Higher 1.2-mA/channel supply current; 0.55-V/µs slew rate; 22-nV/√Hz noise at 1 kHz. | Optimized for ultra-low-power (not ultra-low-noise) applications; less suitable for precision sensor front-ends. | Select TLV2432IDR only when supply current <1.5 mA/channel is mandatory and noise <15 nV/√Hz is acceptable. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift; 5.5 µVpp 0.1–10 Hz noise; 0.17 mA/channel supply current. | Superior DC precision but lower 350-kHz GBW and 0.16-V/µs slew rate limits AC performance. | Choose OPA2333AIDR for DC-critical applications (e.g., weigh scales) where long-term offset stability outweighs bandwidth needs. |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2272AID uniquely balances rail-to-rail output, 3.6-V/µs slew rate, and 9-nV/√Hz noise at moderate 2.4–3 mA supply current - making it optimal for medium-speed, medium-precision analog signal chains where both AC fidelity and DC accuracy matter.

FAQ
What is the maximum supply voltage range supported by the TLC2272AID?
The TLC2272AID supports a dual-supply range of ±2.2 V to ±8 V or a single-supply range of 4.4 V to 16 V. Absolute maximum ratings specify ±8 V on VDD+ and VDD− terminals. Operation beyond these limits risks permanent damage. Recommended conditions ensure reliable performance across industrial temperature ranges (–40°C to 125°C for I-grade variants).
Does the TLC2272AID feature rail-to-rail input capability?
No, the TLC2272AID does not provide rail-to-rail input common-mode range. Its common-mode input voltage extends to the negative rail (VDD− or GND) but only up to (VDD+ −1.5 V) on the positive side. This allows ground-referenced sensor interfaces but requires input signal limiting or level shifting for full-rail input signals.
What is the guaranteed maximum input offset voltage for the TLC2272AID at room temperature?
The TLC2272AID guarantees a maximum input offset voltage of 950 µV at TA = 25°C, as specified in the "TLC2272 and TLC2272A Electrical Characteristics" tables for both VDD = 5 V and VDD± = ±5 V conditions. This is a key differentiator from the base TLC2272 variant, which has a 2500-µV maximum.
Can the TLC2272AID drive capacitive loads directly?
The TLC2272AID is characterized with 100-pF capacitive load in key AC specifications (e.g., slew rate, settling time, phase margin). While it remains stable under this condition, driving larger capacitive loads (>500 pF) may require isolation resistance or external compensation per TI's Application Report SLOA061 to maintain phase margin above 50°.
Is the TLC2272AID pin-compatible with the TLC2272ID?
Yes, the TLC2272AID and TLC2272ID share identical SOIC-8 pinout, electrical connections, and package dimensions. The "A" suffix denotes tighter input offset voltage specification (≤950 µV vs. ≤2500 µV), while all other pin functions, supply requirements, and thermal characteristics remain unchanged - enabling drop-in replacement in existing designs where enhanced DC precision is needed.
