Product details
Overview
TLV2262QDRG4 from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage, low-power applications. It delivers 950 µV max input offset voltage (TA = 25°C), 12 nV/√Hz input voltage noise at 1 kHz, and 500 µA max supply current per amplifier across 2.7 V to 8 V supply range. Its common-mode input voltage range includes the negative rail, enabling single-supply sensor signal conditioning in automotive battery monitoring systems.
For engineers reviewing the TLV2262QDRG4 datasheet, TLV2262QDRG4 pinout, TLV2262QDRG4 application, or TLV2262QDRG4 equivalent, key selection criteria include guaranteed rail-to-rail output swing, automotive-grade temperature range (−40°C to 125°C), low input bias current (1 pA typ), and compatibility with 3-V ADC interfaces in space-constrained embedded designs.
Technical Context
The TLV2262QDRG4 employs Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω) and low noise while maintaining rail-to-rail output capability. Its input stage supports common-mode voltages down to VDD−, and its output can swing within 10 mV of either rail under light load.
This device is fully characterized at 3 V and 5 V, with specified performance over −40°C to 125°C. It features 0.67 MHz gain-bandwidth product and 0.35 V/µs typical slew rate at unity gain, making it suitable for DC-coupled precision amplification rather than high-frequency AC signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - Enables direct operation from single-cell Li-ion or automotive 3.3-V/5-V rails without regulation. |
| Input Offset Voltage | 950 µV max at TA = 25°C - Ensures <1 mV DC error in precision sensor front-ends like thermopile or strain gauge amplifiers. |
| Supply Current per Amplifier | 500 µA max - Supports multi-channel, always-on monitoring in battery-powered automotive modules with sub-1-mA total quiescent draw. |
| Input Voltage Noise | 12 nV/√Hz at f = 1 kHz - Critical for preserving SNR in low-level piezoelectric transducer or microphone preamplifier stages. |
| Common-Mode Input Range | Includes VDD− - Allows direct connection to ground-referenced sensors without level-shifting circuitry. |
| Output Swing | Rail-to-rail - Maximizes dynamic range when driving SAR or delta-sigma ADCs operating at same supply voltage. |
| Operating Temperature | −40°C to 125°C - Qualified for under-hood automotive applications per AEC-Q100 requirements. |
Pinout & Package
TLV2262QDRG4 is housed in an 8-pin SOIC (D) package with standard dual-opamp pinout. The G4 suffix denotes green (lead-free) RoHS-compliant finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Amplified output of first op-amp; capable of rail-to-rail swing into ≥10-kΩ load. |
| 2 | Channel 1 Inverting Input | Differential input node; high-impedance (10¹² Ω) CMOS input for minimal loading of high-Z sources. |
| 3 | Channel 1 Non-Inverting Input | Differential input node; supports common-mode voltage down to VDD− (ground in single-supply config). |
| 4 | VDD− / Ground | Reference terminal for single-supply operation; also serves as return path for both amplifiers. |
| 5 | VDD+ | Positive supply rail; accepts 2.7–8 V; decoupling capacitor required near pin for stability. |
| 6 | Channel 2 Output | Amplified output of second op-amp; electrically isolated but shares same supply and ground. |
| 7 | Channel 2 Inverting Input | Independent differential input; identical electrical characteristics to Pin 2. |
| 8 | Channel 2 Non-Inverting Input | Independent differential input; identical electrical characteristics to Pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full supply voltage utilization-e.g., 0 V to 3.3 V output with 3.3-V supply-maximizing ADC resolution. |
| Low input bias current (1 pA typ) | Minimizes voltage error across high-value feedback resistors (>1 MΩ), critical for pH electrode or photodiode amplifiers. |
| Low-noise architecture (12 nV/√Hz) | Preserves signal integrity in low-amplitude sensor outputs where thermal noise dominates system noise floor. |
| Automotive Q-temp qualification | Guaranteed operation over −40°C to 125°C with controlled parametric drift-no derating needed for engine bay placement. |
| Single-supply compatible input stage | Accepts inputs at ground potential without phase reversal or increased offset, eliminating need for negative bias supplies. |
Applications
| Automotive Battery Monitoring | Piezoelectric Sensor Signal Conditioning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2262IDR | Commercial temperature grade (0°C to 70°C); 2.5 mV max input offset voltage vs. 950 µV for TLV2262QDRG4. | Not qualified for automotive under-hood use; suitable for consumer or industrial indoor environments. | Select TLV2262IDR only if ambient temperature stays below 70°C and offset budget allows ±2.5 mV error. |
| TLV2432CDR | Higher output drive (±25 mA vs. ±50 mA short-circuit); wider input voltage range (VDD− to VDD+ −1.5 V); no rail-to-rail output. | Better suited for driving heavier loads (e.g., relays, LEDs) but sacrifices output dynamic range near supply rails. | Choose TLV2432CDR when interfacing with legacy 5-V ADCs requiring >3-V headroom or driving moderate loads. |
Compared with TLV2262IDR, TLV2262QDRG4 provides tighter offset and extended temperature range essential for automotive reliability; compared with TLV2432CDR, it trades output current capability for rail-to-rail swing and lower noise-making it superior for precision, low-power sensing.

FAQ
What is the maximum operating temperature range for TLV2262QDRG4?
The TLV2262QDRG4 is rated for continuous operation from −40°C to 125°C. This automotive-grade temperature range is validated per AEC-Q100 stress testing and supports deployment in engine control units, battery management systems, and other under-hood applications where ambient temperatures exceed 105°C.
Does TLV2262QDRG4 support true rail-to-rail input?
No, TLV2262QDRG4 does not support rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD−) but stops 1.3 V below the positive rail (VDD+ −1.3 V) at 3 V supply. However, it does provide rail-to-rail output swing, which is explicitly confirmed in the datasheet and critical for ADC interface efficiency.
What is the typical supply current consumption of TLV2262QDRG4 per amplifier?
The TLV2262QDRG4 draws 400 µA typical and 500 µA maximum supply current per amplifier at 25°C with no load. Total device current is therefore 800 µA typical and 1 mA maximum, making it suitable for always-on, low-duty-cycle monitoring functions in energy-constrained automotive subsystems.
Can TLV2262QDRG4 drive capacitive loads directly?
TLV2262QDRG4 is stable with up to 100 pF capacitive load when configured with unity-gain feedback and 50-kΩ load resistance, as verified in the datasheet's operating characteristics. For larger capacitive loads (e.g., long PCB traces or ADC input capacitance >100 pF), external isolation resistance or gain ≥2 is recommended to maintain phase margin above 55°.
Is TLV2262QDRG4 pin-compatible with older TI op-amps like TLV2332?
Yes, TLV2262QDRG4 uses the same 8-pin SOIC (D) package and pinout as TLV2332, enabling drop-in replacement in existing designs. It improves upon TLV2332 with lower noise (12 nV/√Hz vs. 25 nV/√Hz), lower input offset voltage (950 µV max vs. 3 mV max), and enhanced rail-to-rail output swing-without requiring PCB layout changes.
