Product details
Overview
TLC2262AIP 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 950 µV max input offset voltage at 25°C, 12 nV/√Hz input voltage noise at 1 kHz, 500 µA max supply current, and full rail-to-rail output swing - enabling direct interfacing with 5-V ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLC2262AIP datasheet, TLC2262AIP pinout, TLC2262AIP application, or TLC2262AIP equivalent, key selection criteria include its guaranteed low VIO over –40°C to 125°C, CMOS input bias current ≤1 pA, and operation down to ±2.2 V supplies - critical for high-impedance piezoelectric transducer amplification and portable medical monitoring circuits.
Technical Context
The TLC2262AIP 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). Its input stage includes common-mode range extending to the negative rail, supporting true single-supply operation with inputs referenced to ground.
It features fully characterized performance across –40°C to 125°C, with guaranteed 950 µV max VIO, 0.35–0.55 V/µs slew rate, and 70–83 dB CMRR - making it suitable for precision instrumentation where thermal drift and power supply rejection must remain stable over automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 950 µV max at 25°C - ensures <1 LSB error when driving 12-bit 5-V ADCs without trimming |
| Supply Current | 500 µA max per amplifier - enables dual-channel operation under 1 mA total, ideal for coin-cell or energy-harvesting systems |
| Input Bias Current | 1 pA typ - preserves signal integrity from >1 GΩ sources like pH electrodes or piezoelectric sensors |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - 3× lower than predecessor TLC27M2, improving SNR in audio and sensor preamps |
| Rail-to-Rail Output | Swings within 10 mV of both rails at 50 µA load - maximizes dynamic range when paired with SAR or sigma-delta ADCs |
| Common-Mode Input Range | Includes negative rail (VDD–) - allows ground-referenced input signals in single-supply configurations |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial control applications |
Pinout & Package
Package: 8-pin Plastic DIP (P), industry-standard through-hole format with 0.3-inch body width and 0.1-inch lead pitch - compatible with legacy PCB layouts and wave-solder processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives loads up to ±50 mA; rail-to-rail swing supports full 5-V ADC input range |
| 2 | IN1– | Inverting input - high-impedance CMOS node; requires matched trace impedance for optimal CMRR |
| 3 | IN1+ | Non-inverting input - accepts signals from VDD– to VDD+ –1.5 V; enables true single-supply sensor biasing |
| 4 | VDD–/GND | Negative supply or ground reference - serves as common return for both amplifiers and input sources |
| 5 | VDD+ | Positive supply - operates from ±2.2 V to ±8 V; decoupling capacitor required at pin for stability |
| 6 | OUT2 | Amplifier 2 output - independent channel; shares same supply pins for compact dual-signal conditioning |
| 7 | IN2– | Inverting input (amp 2) - electrically isolated from amp 1; supports differential or independent gain stages |
| 8 | IN2+ | Non-inverting input (amp 2) - identical electrical characteristics to IN1+; enables matched dual-channel design |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full 5-V peak-to-peak output into 50 kΩ at 5 V supply - eliminates level-shifting circuitry before ADCs |
| Low input offset voltage grade | 950 µV max (A-grade) - reduces calibration overhead in factory-trimmed industrial analog modules |
| Ultra-low input bias current | 1 pA typical - prevents signal attenuation and DC error in high-Z transducer interfaces (e.g., electret mics, strain gauges) |
| Low-noise CMOS architecture | 12 nV/√Hz at 1 kHz - outperforms bipolar op-amps in low-frequency sensor applications without added quiescent power |
| Single- and split-supply support | Fully specified from 4.4 V to ±16 V - simplifies migration between battery-powered and line-powered system variants |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2262IP | 2.5 mV max VIO at 25°C (vs. 950 µV for TLC2262AIP); otherwise identical specs and pinout | Acceptable for non-critical signal chains where offset trimming is feasible or post-processing available | Select TLC2262IP only if cost sensitivity outweighs need for guaranteed low-offset performance across temperature |
| TLV2432IDR | Higher drive capability (60 mA vs. ±50 mA), lower noise (11 nV/√Hz), but 1.5 mV max VIO; SOIC-8 package only | Better suited for driving heavier capacitive loads or higher-bandwidth sensor interfaces requiring faster settling | Choose TLV2432IDR when board space permits SOIC-8 and application demands sub-100 ns settling to 0.01% |
Compared with TLC2262IP and TLV2432IDR, the TLC2262AIP uniquely balances guaranteed low offset, ultra-low input bias, and through-hole DIP packaging - making it the preferred choice for legacy-replacement, high-reliability, or thermally demanding analog signal paths where calibration headroom and long-term stability are constrained.

FAQ
What is the maximum operating supply voltage for the TLC2262AIP?
The TLC2262AIP supports a maximum supply voltage of ±8 V (or 16 V total across VDD+ and VDD–). Absolute maximum ratings specify ±8 V per supply rail; exceeding this risks permanent damage. For reliable operation, TI recommends staying within ±2.2 V to ±8 V as defined in recommended operating conditions - with 5 V single-supply (VDD+ = 5 V, VDD– = GND) being the most common configuration used with the TLC2262AIP.
Does the TLC2262AIP support true single-supply operation with inputs referenced to ground?
Yes, the TLC2262AIP supports true single-supply operation. Its common-mode input voltage range includes the negative rail (VDD–/GND), allowing inputs to be referenced directly to ground. When powered from a 5 V single supply (VDD+ = 5 V, VDD– = GND), the input common-mode range extends from 0 V to 3.5 V over temperature - enabling ground-referenced sensor interfaces without level-shifting circuitry. This capability is explicitly confirmed in the recommended operating conditions table for the TLC2262AIP.
What is the guaranteed input offset voltage specification for the TLC2262AIP over temperature?
The TLC2262AIP guarantees a maximum input offset voltage of 950 µV at TA = 25°C and 1500 µV over the full operating range of –40°C to +125°C. This A-grade specification is clearly differentiated from the standard TLC2262IP (2.5 mV max) in the device options table. The temperature coefficient is 2 µV/°C, meaning offset drift remains tightly bounded - critical for uncalibrated systems operating across wide ambient conditions.
Can the TLC2262AIP drive capacitive loads without instability?
The TLC2262AIP is stable with capacitive loads up to 100 pF when configured with unity-gain feedback and a 50 kΩ load, as verified by phase margin (56°) and gain margin (11 dB) measurements in the datasheet. For loads exceeding 100 pF, TI recommends adding a small series resistor (e.g., 10–50 Ω) between the output and the capacitor to isolate the reactive load - a standard technique documented in TI's "Stability Analysis of Op Amps Driving Capacitive Loads." This behavior applies directly to the TLC2262AIP and is validated in its operating characteristics tables.
Is the TLC2262AIP pin-compatible with older TI op-amps like the TLC27M2?
Yes, the TLC2262AIP is pin-compatible with the TLC27M2 in the 8-pin DIP (P) package - sharing identical pinout (OUT1, IN1–, IN1+, GND, VCC, OUT2, IN2–, IN2+). However, it is not a drop-in replacement in all designs: the TLC2262AIP offers rail-to-rail output, lower noise (12 nV/√Hz vs. 25 nV/√Hz), lower input bias current (1 pA vs. 60 pA), and improved CMRR. These enhancements may require minor layout review (e.g., updated decoupling, reduced trace inductance) but no PCB redesign is needed for basic functional replacement of the TLC27M2 with the TLC2262AIP.
