Product details
Overview
TLC2262AQDG4 from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for automotive-grade operation (–40°C to 125°C), featuring 950 µV max input offset voltage, 12 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 500 µA max supply current per amplifier. It enables high-precision signal conditioning in single-supply sensor interfaces and ADC driver stages.
For engineers reviewing the TLC2262AQDG4 datasheet, TLC2262AQDG4 pinout, TLC2262AQDG4 application, or TLC2262AQDG4 equivalent, this device is selected for low-noise, low-power, rail-to-rail output performance in automotive temperature-critical analog front-ends where input common-mode range includes the negative rail and output swing reaches both supply rails.
Technical Context
The TLC2262AQDG4 uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input bias current (1 pA typ) and low noise (12 nV/√Hz). Its input stage supports common-mode voltage down to VDD–, enabling true single-supply operation with ground-referenced inputs.
It delivers 0.55 V/µs slew rate and 0.73 MHz gain-bandwidth product under ±5 V supplies, with phase margin of 57° and 11 dB gain margin into 50 kΩ//100 pF loads - ensuring stable unity-gain buffer and closed-loop configurations without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 500 µA max per amplifier - enables battery-powered automotive modules with multi-channel analog sensing. |
| Input Offset Voltage | 950 µV max at TA = 25°C - supports precision DC-coupled amplification in thermocouple or strain gauge interfaces. |
| Input Bias Current | 1 pA typ - preserves signal integrity when driving from high-impedance sources like piezoelectric sensors. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs operating at same supply (e.g., 5 V or ±5 V), minimizing headroom loss. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - reduces contribution to system noise floor in audio preamps and sensor signal chains. |
| Common-Mode Input Range | Includes VDD– - allows direct interfacing with ground-referenced transducers without level-shifting circuitry. |
| Slew Rate | 0.55 V/µs - supports accurate reproduction of signals up to ~85 kHz full-power bandwidth (VO(PP) = 4.6 V). |
Pinout & Package
Package: SOIC-8 (D package), RoHS-compliant, surface-mount, 150 mil width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives load directly; rail-to-rail swing supports full-scale ADC input. |
| 2 | IN– A | Inverting input of Amplifier A - high-impedance node (10¹² Ω) for feedback networks or differential sensing. |
| 3 | IN+ A | Non-inverting input of Amplifier A - accepts ground-referenced or biased sensor signals within VDD– to VDD+–1.5 V. |
| 4 | GND / VDD– | Negative supply or ground reference - shared return path for both amplifiers; supports single- or split-supply operation. |
| 5 | IN+ B | Non-inverting input of Amplifier B - independent channel for dual-sensor conditioning or signal splitting. |

Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 10 mV of VDD+ and VDD– under 100 µA load - maximizes usable ADC input range without external level-shifting. |

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 slew rate (1.5 V/µs), lower supply current (425 µA typ), but only 2.5 mV max VIO and not AEC-Q100 qualified. | Preferred for consumer portable devices needing faster response; unsuitable for automotive temperature-critical precision roles. | Select TLV2432IDR only for non-automotive, cost-sensitive designs where 2.5 mV VIO is acceptable and extended temperature range is unnecessary. |
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C drift), 12 µV max VIO, but higher supply current (17 µA) and no rail-to-rail output (clips ~200 mV from rails). | Better for ultra-low-drift DC applications (e.g., weigh scales); incompatible with rail-to-rail ADC drivers requiring full swing. | Choose OPA2333AIDR when long-term DC stability dominates over output swing and power; avoid when driving SAR or sigma-delta ADCs requiring full-scale input. |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2262AQDG4 uniquely balances automotive qualification, rail-to-rail output, sub-millivolt offset, and micropower consumption - making it the only option among the three qualified for AEC-Q100 Grade 2 environments with simultaneous DC precision and dynamic range requirements.

FAQ
What is the maximum operating temperature range for the TLC2262AQDG4?
The TLC2262AQDG4 is rated for operation from –40°C to +125°C, meeting AEC-Q100 Grade 2 automotive qualification requirements. This extended range is confirmed in the "TLC2262 AVAILABLE OPTIONS" table where the Q suffix denotes –40°C to 125°C operation, and the D package (SOIC-8) is explicitly listed for the TLC2262AQD variant.
Does the TLC2262AQDG4 support true single-supply operation with ground-referenced inputs?
Yes, the TLC2262AQDG4 supports true single-supply operation: its common-mode input voltage range includes the negative rail (VDD–/GND), and its output swings rail-to-rail. The datasheet specifies VICR from VDD– to VDD+–1.5 V and VOM– within 10 mV of VDD– under load - enabling direct interface with 0 V-referenced sensors without external biasing.
What is the input offset voltage specification for the TLC2262AQDG4, and how does it differ from the standard TLC2262QDG4?
The TLC2262AQDG4 has a maximum input offset voltage of 950 µV at TA = 25°C, as stated in the "TLC2262 AVAILABLE OPTIONS" table under the "VIO max at 25°C" column for the "A" grade. In contrast, the non-A version (e.g., TLC2262QDG4) is specified at 2.5 mV max - the "A" suffix denotes enhanced precision trimming for applications demanding tighter DC accuracy.
Can the TLC2262AQDG4 drive capacitive loads without instability?
The TLC2262AQDG4 is characterized for stability with 100 pF capacitive loads in unity-gain configuration, showing 57° phase margin and 11 dB gain margin at ±5 V supplies. However, the datasheet does not guarantee stability with larger capacitive loads; for >100 pF, external isolation resistance (e.g., 10–100 Ω in series with output) is recommended to maintain phase margin above 45°.
Is the TLC2262AQDG4 pin-compatible with legacy TI op-amps like the TLC27M2?
Yes, the TLC2262AQDG4 is pin-compatible with the TLC27M2 in the SOIC-8 (D) package, as confirmed by the "Performance Upgrade for the TS27M2/M4 and TLC27M2/M4" statement and identical pinout diagrams for D-package dual op-amps. This allows drop-in replacement to improve output swing, noise, and input offset without PCB redesign.
