Product details
Overview
TLC2262QDR from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for automotive-grade applications. It delivers 12 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 500 µA maximum supply current per amplifier, operating from ±2.2 V to ±8 V supplies. It supports single- or split-supply configurations and is used in precision sensor signal conditioning and ADC interface circuits where low-noise, low-power, and rail-to-rail swing are critical.
For engineers reviewing the TLC2262QDR datasheet, TLC2262QDR pinout, TLC2262QDR application, or TLC2262QDR equivalent, this device is selected for battery-powered automotive sensors, high-impedance piezoelectric transducer interfaces, and analog front-ends requiring guaranteed operation across –40°C to 125°C with rail-to-rail output swing and sub-microamp input bias.
Technical Context
The TLC2262QDR uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input impedance (10¹² Ω differential and common-mode) and ultra-low input bias current (1 pA typ). Its architecture enables stable unity-gain operation with 56° phase margin and 11 dB gain margin under 50 kΩ load and 100 pF capacitive load conditions.
It is fully specified for both single-supply (e.g., 5 V) and split-supply (e.g., ±5 V) operation, with common-mode input range extending to the negative rail and output swing within 10 mV of both rails at light loads. The device exhibits 0.35–0.55 V/µs slew rate and 0.71 MHz gain-bandwidth product at 5 V supply.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 10 mV of VDD+ and GND at IOUT = ±20 µA - maximizes usable ADC input range in 3.3 V or 5 V systems |
| Ultra-low input bias current | 1 pA typical - preserves signal integrity from high-impedance sources like pH electrodes or piezo elements |
| Low input voltage noise | 12 nV/√Hz at 1 kHz - reduces integrated noise in bandwidth-limited sensor paths (e.g., <10 kHz) |
| Automotive qualification | Q-suffix grade, –40°C to 125°C operation, and configuration control per TI automotive standards - suitable for ASIL-B supporting functions |
| Single- and split-supply support | Fully characterized at 5 V and ±5 V - eliminates need for separate design variants across power architectures |

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), higher supply current (1.4 mA), wider input voltage range (beyond rails) | Better suited for higher-speed active filters or driving capacitive loads >1000 pF | Select TLV2432IDR when bandwidth >1 MHz or drive strength >20 mA is required; not drop-in due to higher IQ and different offset specs |
| OPA2333AIDR | Zero-drift architecture, 0.02 µV/°C offset drift, 60 nA max supply current, but only 360 kHz GBW | Superior DC precision for long-term stability in calibration-critical systems (e.g., weigh scales) | Choose OPA2333AIDR for µV-level offset stability over temperature; TLC2262QDR preferred for broader AC bandwidth and lower noise at 1 kHz |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2262QDR offers the optimal balance of low noise (12 nV/√Hz), ultra-low bias current (1 pA), and automotive temperature rating in a cost-effective SOIC-8 package - making it ideal for sensor signal chains where precision, power, and reliability must coexist without zero-drift complexity or excessive quiescent draw.

FAQ
What is the maximum operating temperature range for the TLC2262QDR?
The TLC2262QDR is rated for continuous operation from –40°C to 125°C, meeting automotive under-hood environmental requirements. This specification is validated per TI's Q-temp qualification standard and includes full electrical characterization across the range, including input offset voltage, common-mode range, and output swing performance.
Does the TLC2262QDR support true single-supply operation with input referenced to ground?
Yes, the TLC2262QDR supports true single-supply operation: its common-mode input voltage range includes the negative rail (GND), and its output swings rail-to-rail. When powered from 5 V (VDD+ = 5 V, VDD– = GND), the input can be as low as 0 V, and the output can reach within 10 mV of both 0 V and 5 V - enabling direct interface with unipolar ADCs without level-shifting circuitry.
What is the input offset voltage specification for the TLC2262QDR?
The TLC2262QDR has a maximum input offset voltage of 2.5 mV at 25°C and across its full operating temperature range (–40°C to 125°C). This value applies to the "Q" grade variant as documented in the SLOS177D datasheet revision March 2001, and is distinct from the tighter 950 µV spec of the TLC2262AQD variant.
Can the TLC2262QDR drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes - the TLC2262QDR maintains rail-to-rail output swing into 10 kΩ loads. Datasheet specifications confirm VOH ≥ 4.99 V and VOL ≤ 0.01 V at VDD = 5 V and IOUT = ±20 µA. Even at ±1 mA, output swing remains within 100 mV of the rails, ensuring compatibility with standard ADC input impedances and passive RC filtering stages.
Is the TLC2262QDR pin-compatible with legacy TLC27M2 or TS27M2 op-amps?
No - the TLC2262QDR is not pin-compatible with TLC27M2 or TS27M2. While it serves as a functional upgrade (offering rail-to-rail output, lower noise, and lower input bias current), its SOIC-8 pinout differs: TLC2262QDR uses standard dual-op-amp configuration (IN+/IN–/OUT per channel), whereas TLC27M2 uses non-standard pin assignments. PCB redesign is required for migration.
