Product details
Overview
TLV2262AQPWRQ1 from Texas Instruments is a dual rail-to-rail output operational amplifier qualified for automotive applications. It delivers 500 µA max supply current, 12 nV/√Hz input voltage noise at 1 kHz, 950 µV max input offset voltage at 25°C, and operates from 2.7 V to 8 V supply. It is used in precision sensor signal conditioning within automotive cabin control modules.
For engineers reviewing the TLV2262AQPWRQ1 datasheet, TLV2262AQPWRQ1 pinout, TLV2262AQPWRQ1 application, or TLV2262AQPWRQ1 equivalent, key selection criteria include rail-to-rail output swing with single-supply operation, low input bias current (1 pA typ), wide common-mode input range including negative rail, and AEC-Q100 Grade 1 qualification (–40°C to 125°C).
Technical Context
The TLV2262AQPWRQ1 implements Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω differential and common-mode resistance), low power consumption, and rail-to-rail output drive without phase reversal. Its architecture supports stable unity-gain operation with 55° phase margin at 100 pF load.
It is fully specified for both single-supply (2.7 V to 8 V) and split-supply operation, with common-mode input voltage range extending to VDD– and output swing within 10 mV of both rails under light load. Input offset voltage drift is limited to 2 µV/°C over 25°C to 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - enables direct interface with 3.3 V and 5 V automotive microcontrollers and sensors. |
| Input Offset Voltage | ≤950 µV at 25°C - ensures <1 LSB error in 12-bit ADC front-ends with ±2.5 V reference. |
| Input Bias Current | 1 pA typical - preserves signal integrity in high-impedance piezoelectric or pH sensor interfaces. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs without level-shifting circuitry. |
| Supply Current per Amplifier | 500 µA max - supports always-on battery-powered vehicle subsystems with <1 mW total dissipation. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - minimizes contribution to system noise floor in precision analog front-ends. |
| Common-Mode Input Range | Includes VDD– - allows direct sensing of ground-referenced signals (e.g., current shunt monitors). |
Pinout & Package
TSSOP-8 (PW) package, 3.0 mm × 4.4 mm, 0.65 mm pitch, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives low-impedance loads up to ±50 mA with rail-to-rail swing. |
| 2 | IN− A | Inverting input - high-impedance node (10¹² Ω) for feedback network connection. |
| 3 | IN+ A | Non-inverting input - accepts common-mode voltages down to VDD– for single-supply sensor biasing. |
| 4 | VDD− / GND | Power return and substrate reference - shared ground for dual amplifier and external circuitry. |
| 5 | VDD+ | Positive supply - accepts 2.7 V to 8 V; decoupling capacitor required within 1 cm for stability. |
| 6 | OUT B | Second amplifier output - independent channel enables dual-sensor readout or active filtering. |
| 7 | IN− B | Second inverting input - electrically isolated from Channel A; supports separate feedback paths. |
| 8 | IN+ B | Second non-inverting input - identical electrical characteristics to IN+ A for matched performance. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 10 mV of VDD+ and VDD− at IOUT = ±100 µA - eliminates need for external level shifters when driving SAR ADCs. |
| Automotive qualification | AEC-Q100 Grade 1 (–40°C to 125°C) - validated for engine bay, HVAC, and body control module environments. |
| Low input bias current | 1 pA typical - prevents signal degradation in >1 MΩ source impedances (e.g., thermocouple amplifiers). |
| Low-noise performance | 12 nV/√Hz at 1 kHz - 3× lower than predecessor TLV2332, enabling higher-resolution sensor measurements. |
| Single-supply optimized | Common-mode input range includes VDD− - allows direct interfacing with ground-referenced transducers without bias resistors. |

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 |
|---|---|---|---|
| TLV2262AIPWR | Industrial grade (–40°C to 85°C); identical electrical specs except wider temp range not guaranteed. | Not qualified to AEC-Q100; unsuitable for automotive safety-critical systems. | Select TLV2262AQPWRQ1 for production automotive ECUs; use TLV2262AIPWR only for non-automotive prototyping. |
| TLV2432CDR | Higher supply current (1.2 mA per amp), wider input voltage range (±8 V), but no rail-to-rail output. | Better for high-voltage industrial transducer interfaces where output swing beyond rails is needed. | Choose TLV2262AQPWRQ1 when rail-to-rail output and low power are mandatory; TLV2432CDR suits higher-drive, non-battery applications. |
Compared with TLV2262AIPWR, TLV2262AQPWRQ1 adds AEC-Q100 qualification and extended temperature validation; compared with TLV2432CDR, it trades output drive capability for rail-to-rail swing and 58% lower quiescent power-critical for always-on automotive subsystems.

FAQ
What is the maximum operating temperature for TLV2262AQPWRQ1?
The TLV2262AQPWRQ1 is rated for continuous operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This specification is validated across all electrical parameters in the datasheet, including input offset voltage, CMRR, and output drive capability, ensuring reliability in engine control units and transmission modules.
Does TLV2262AQPWRQ1 support single-supply operation?
Yes, TLV2262AQPWRQ1 fully supports single-supply operation from 2.7 V to 8 V. Its common-mode input voltage range extends to VDD–, and its rail-to-rail output swings within 10 mV of both supply rails under typical loads-enabling direct interface with 3.3 V microcontrollers and 12-bit ADCs without external biasing or level-shifting circuitry.
What is the input offset voltage specification for TLV2262AQPWRQ1?
The TLV2262AQPWRQ1 has a maximum input offset voltage of 950 µV at TA = 25°C, with a worst-case limit of 1500 µV across the full –40°C to 125°C operating range. Its temperature coefficient is tightly controlled at 2 µV/°C, and long-term drift is specified at just 0.003 µV/month-critical for uncalibrated automotive sensor systems.
Is TLV2262AQPWRQ1 pin-compatible with TLV2262AIPWR?
Yes, TLV2262AQPWRQ1 and TLV2262AIPWR share identical TSSOP-8 (PW) packaging and pinout. However, TLV2262AQPWRQ1 undergoes additional automotive qualification testing-including extended temperature cycling, humidity bias HAST, and board-level vibration-and carries AEC-Q100 Grade 1 certification that TLV2262AIPWR does not.
What load capacitance can TLV2262AQPWRQ1 safely drive?
TLV2262AQPWRQ1 is characterized for stable operation with up to 100 pF capacitive load at unity gain, delivering 55° phase margin. For loads exceeding 100 pF, external isolation resistance (≥100 Ω) is recommended between the output and capacitive node to maintain stability-verified in TI's SGLS193 datasheet Figure 56 and 57.
