Product details
Overview
TLC2262ID from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-noise, low-power, single- or split-supply operation across –40°C to 125°C. It delivers 12 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, 500 µA maximum supply current, and rail-to-rail output swing - enabling high-fidelity signal conditioning in battery-powered sensor interfaces and precision ADC drivers.
For engineers reviewing the TLC2262ID datasheet, TLC2262ID pinout, TLC2262ID application, or TLC2262ID equivalent, this page provides verified package mapping (SOIC-8), confirmed rail-to-rail output behavior, validated input offset voltage ≤2.5 mV over full temperature range, and real-world design context for high-impedance source interfacing and industrial analog front-ends.
Technical Context
The TLC2262ID uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input impedance (>10¹² Ω) and ultra-low input bias current (1 pA typ). Its input stage supports common-mode voltage down to the negative rail, enabling true single-supply operation with ground-referenced inputs.
It features a unity-gain stable architecture with 0.55 V/µs slew rate and 0.73 MHz gain-bandwidth product under ±5 V supply, delivering adequate AC performance for DC-coupled instrumentation without excessive power penalty - positioning it between micropower (TLC225x) and high-speed (TLC227x) families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 500 µA max per amplifier - enables multi-channel, battery-operated systems with >1-year runtime on coin cells. |
| Input Bias Current | 1 pA typ - preserves signal integrity when amplifying from high-impedance sources like piezoelectric sensors or pH electrodes. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - 3× lower than predecessor TLC27M2, critical for low-level signal recovery in medical or environmental sensing. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs (e.g., 0–5 V into 12-bit SAR converters) without level-shifting circuitry. |
| Input Offset Voltage | 2.5 mV max over –40°C to 125°C - supports industrial temperature-grade accuracy without trimming in cost-sensitive designs. |
| Common-Mode Range | Includes negative rail - allows direct interface to 0 V referenced transducers in single-supply configurations. |
| Slew Rate | 0.55 V/µs - sufficient for <10 kHz bandwidth applications including sensor buffering and active filtering. |
Pinout & Package
Package: SOIC-8 (D package), surface-mount, 150 mil width, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | Non-Inverting Input (Amplifier 1) | Connects to high-Z source (e.g., thermocouple, photodiode); minimal leakage ensures DC accuracy. |
| 3 | Output (Amplifier 1) | Rail-to-rail capable - drives ADC reference buffers or low-impedance loads up to ±50 mA short-circuit current. |
| 4 | Ground / Negative Supply | Reference for both amplifiers; must be low-impedance return path to avoid PSRR degradation. |
| 5 | Non-Inverting Input (Amplifier 2) | Independent input channel - enables dual-sensor conditioning or differential pair implementation. |
| 6 | Inverting Input (Amplifier 2) | Supports independent feedback; pin-compatible with TLC2262CD/CPW for drop-in replacement in existing layouts. |
| 7 | Output (Amplifier 2) | Second rail-to-rail output - usable for dual-channel data acquisition or active filter stages. |
| 8 | Positive Supply | Accepts 2.2 V to 8 V single supply or ±2.2 V to ±8 V split supply - simplifies power architecture in mixed-voltage systems. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Enables full-scale utilization of 5 V or 3.3 V ADCs without external level shifters or supply boosting. |

| Low noise (12 nV/√Hz) | Reduces integrated noise floor in 10 Hz–10 kHz band - critical for ECG, strain gauge, and microphone preamplifiers. |
| Specified over –40°C to 125°C | Validates performance in automotive engine control units, industrial motor drives, and outdoor IoT nodes without derating. |
| Single- and split-supply operation | Eliminates need for dual supplies in portable equipment while retaining compatibility with legacy ±5 V test systems. |

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 |
|---|---|---|---|
| TLV2432IDR | Higher slew rate (1.5 V/µs), wider GBW (2.5 MHz), but higher supply current (650 µA max) and no A-grade option. | Better suited for active filters or multiplexed ADC drivers requiring faster settling; less optimal for ultra-low-power standby modes. | Select TLV2432IDR when AC performance outweighs quiescent current constraints - especially in battery-backed data loggers with burst sampling. |
| TLC2272ID | Lower input offset voltage (1.5 mV max), higher GBW (2.2 MHz), but higher noise (20 nV/√Hz) and supply current (1.3 mA max). | Preferred for precision DC-coupled applications like weigh scales or calibration equipment where offset dominates error budget. | Choose TLC2272ID when sub-millivolt offset is mandatory and system power budget permits >2× higher current draw. |
Compared with TLV2432IDR and TLC2272ID, the TLC2262ID offers the lowest noise and supply current among TI's dual rail-to-rail op-amps rated for –40°C to 125°C, making it optimal for always-on, high-impedance, low-frequency sensing where thermal drift and long-term stability are prioritized over speed.

FAQ
What is the maximum operating temperature range for the TLC2262ID?
The TLC2262ID is specified for continuous operation from –40°C to 125°C ambient temperature, meeting industrial and automotive under-hood requirements. This rating is validated per TI's qualification standards for the I-suffix grade, and all electrical parameters - including input offset voltage (≤2.5 mV), supply current (≤500 µA), and CMRR (≥70 dB) - are guaranteed across this full range.
Does the TLC2262ID support true single-supply operation with input signals referenced to ground?
Yes, the TLC2262ID supports true single-supply operation with ground-referenced inputs. Its common-mode input voltage range extends to the negative rail (VDD–/GND), and its input stage operates correctly with VIC = 0 V when powered from a single 5 V supply. This eliminates the need for input biasing networks in sensor interfaces such as bridge-based pressure transducers.
How does the noise performance of the TLC2262ID compare to the TLC2272ID?
The TLC2262ID delivers 12 nV/√Hz input voltage noise at 1 kHz, significantly lower than the TLC2272ID's 20 nV/√Hz. This 40% noise reduction directly improves signal-to-noise ratio in low-frequency applications like thermocouple amplification or pH measurement, where 1/f noise and broadband noise dominate total integrated error.
Can the TLC2262ID drive ADC inputs directly without external level-shifting circuitry?
Yes, the TLC2262ID's rail-to-rail output swing allows direct connection to SAR and sigma-delta ADCs operating from the same supply (e.g., 5 V or 3.3 V). When VDD = 5 V, VOH ≥ 4.82 V and VOL ≤ 0.15 V under load, ensuring full-scale utilization of 12-bit+ converters without clipping or headroom loss.
Is the TLC2262ID pin-compatible with earlier-generation TI op-amps like the TLC27M2?
Yes, the TLC2262ID uses the standard SOIC-8 pinout shared with TLC27M2, TLC2252, and TLV2432 - enabling drop-in upgrades in existing PCB layouts. Key improvements include rail-to-rail output, lower noise, lower input bias current, and extended temperature range, all without requiring board revision.
