Product details
Overview
TLV2262IDRG4 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 - enabling precision signal conditioning in battery-powered sensor interfaces and portable medical devices.
For engineers reviewing the TLV2262IDRG4 datasheet, TLV2262IDRG4 pinout, TLV2262IDRG4 application, or TLV2262IDRG4 equivalent, key selection considerations include its guaranteed rail-to-rail output swing, −40°C to 125°C automotive-grade temperature rating, and compatibility with single-supply ADC driver circuits requiring high input impedance and low noise.
Technical Context
The TLV2262IDRG4 uses Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω), ultra-low input bias current (1 pA typ), and common-mode input voltage range extending to the negative rail. Its architecture supports stable unity-gain operation with 55° phase margin and 11 dB gain margin under 50 kΩ load and 100 pF capacitive load conditions.
It is fully characterized at 3 V and 5 V, with specified performance over −40°C to 125°C. The device exhibits 0.67 MHz gain-bandwidth product, 0.35–0.55 V/µs slew rate, and 395 kHz output-swing bandwidth at 1 VPP - balancing ac performance and micropower consumption for analog front-end stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - enables direct integration into 3.3 V and 5 V systems without level-shifting. |
| Input Offset Voltage | 950 µV max at TA = 25°C - ensures <1 mV dc error in precision sensor amplification paths. |
| Input Voltage Noise | 12 nV/√Hz at f = 1 kHz - critical for low-level piezoelectric or thermopile signal conditioning. |
| Supply Current per Amplifier | 500 µA max - supports >1-year battery life in always-on wearable health monitors. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs with 0–3.3 V or 0–5 V reference rails. |
| Common-Mode Input Range | Includes negative rail (VDD−) - allows direct sensing of ground-referenced signals without biasing. |
| Gain-Bandwidth Product | 0.67 MHz - sufficient for anti-aliasing filters and sensor signal bandwidths up to ~100 kHz. |
Pinout & Package
TLV2262IDRG4 is housed in an 8-pin SOIC (D) package with standard dual-opamp pinout and no internal NC pins. The device is lead-free, RoHS-compliant, and available in tape-and-reel format (R suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Delivers rail-to-rail amplified signal; drives loads ≥2 kΩ directly. |
| 2 | Channel 1 Inverting Input | High-impedance node (10¹² Ω); accepts feedback networks for precise gain setting. |
| 3 | Channel 1 Non-Inverting Input | Accepts high-Z sensor inputs (e.g., pH electrodes, strain gauges) without loading. |
| 4 | VDD− / Ground | Reference return for both amplifiers; must be low-impedance for noise immunity. |
| 5 | VDD+ | Positive supply rail; decoupling capacitor (0.1 µF) required within 1 cm of this pin. |
| 6 | Channel 2 Output | Independent rail-to-rail output; usable for dual-path signal processing or reference buffering. |
| 7 | Channel 2 Inverting Input | Separate feedback path; supports differential configurations with matched external resistors. |
| 8 | Channel 2 Non-Inverting Input | Second high-Z input channel; enables dual-sensor readout or active filtering stages. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives ADCs directly with full-scale utilization - eliminates need for external level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2262CDR | Commercial temperature grade (0°C to 70°C); 2.5 mV max VIO vs. 950 µV for TLV2262IDRG4. | Not qualified for automotive or extended industrial use; unsuitable for designs requiring AEC-Q100 compliance. | Select only for cost-sensitive consumer electronics where ambient temperature remains controlled. |
| OPA2333AIDR | Zero-drift architecture; 2 µV max VIO, 0.02 µV/°C drift, but 17 µA supply current per amp - 34× higher than TLV2262IDRG4. | Better dc precision but incompatible with micropower battery lifetime targets; requires larger PCB area for external compensation. | Choose when ultra-low offset and drift dominate over power budget; avoid when >500 µA total supply current is unacceptable. |
Compared with TLV2262CDR, TLV2262IDRG4 provides tighter offset and extended temperature capability at identical package and pinout; versus OPA2333AIDR, it trades dc precision for 34× lower quiescent current - making it optimal for always-on, long-life sensor nodes where moderate offset is acceptable.

FAQ
What is the maximum operating temperature range for TLV2262IDRG4?
The TLV2262IDRG4 is rated for operation from −40°C to 125°C, meeting automotive-grade thermal requirements. This specification is validated per AEC-Q100 stress testing protocols and applies across the full 2.7 V to 8 V supply range. Performance parameters such as input offset voltage and common-mode rejection ratio are guaranteed over this entire range, making TLV2262IDRG4 suitable for under-hood and industrial control applications where ambient temperatures exceed 105°C.
Does TLV2262IDRG4 support true rail-to-rail input operation?
No, TLV2262IDRG4 features rail-to-rail *output* swing but not 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+) - for example, 0 V to 2.2 V at VDD = 3.3 V. This design enables high-impedance sensing of ground-referenced signals while maintaining CMOS input stage stability. For full rail-to-rail input capability, consider TI's TLV9002 or OPA391 families.
Can TLV2262IDRG4 drive capacitive loads directly?
TLV2262IDRG4 is stable with up to 100 pF capacitive load when driving a 50 kΩ resistive load, as verified by 55° phase margin and 11 dB gain margin in the datasheet. Driving larger capacitive loads (e.g., >200 pF) requires isolation resistance (≥500 Ω) in series with the output to prevent peaking or oscillation. This limitation is inherent to its unity-gain compensated architecture and must be accounted for in ADC driver or filter stage designs using TLV2262IDRG4.
What is the typical input bias current of TLV2262IDRG4 at 85°C?
The typical input bias current of TLV2262IDRG4 is 1 pA at 25°C and increases to 150 pA at 85°C, as specified in the electrical characteristics table for the I suffix grade. This temperature-dependent leakage remains exceptionally low compared to bipolar-input op-amps and preserves signal fidelity in high-impedance sensor interfaces even at elevated operating temperatures. The value is measured with VDD = 3 V and VIC = 0 V.
Is TLV2262IDRG4 pin-compatible with TLV2262CDR?
Yes, TLV2262IDRG4 and TLV2262CDR share identical SOIC-8 (D) package dimensions, pinout, and footprint. Both devices use the same 1OUT/1IN−/1IN+/GND/VDD+/2OUT/2IN−/2IN+ assignment. However, TLV2262IDRG4 offers tighter input offset voltage (950 µV max vs. 2.5 mV max) and extended temperature range (−40°C to 125°C vs. 0°C to 70°C), making it a drop-in upgrade for designs requiring enhanced precision and environmental robustness.
