Product details
Overview
TLV2262QDR from Texas Instruments is a dual rail-to-rail output CMOS operational amplifier optimized for low-voltage, low-power applications. It delivers 950 µV max input offset voltage, 12 nV/√Hz input voltage noise at 1 kHz, 500 µA max supply current per amplifier, and operates from 2.7 V to 8 V supply. It is used in precision signal conditioning for high-impedance piezoelectric sensors and battery-powered remote sensing systems.
For engineers reviewing the TLV2262QDR datasheet, TLV2262QDR pinout, TLV2262QDR application, or TLV2262QDR equivalent, key selection criteria include its rail-to-rail output swing, sub-1 pA input bias current at 25°C, guaranteed automotive temperature range (−40°C to 125°C), and compatibility with single-supply ADC interfacing circuits requiring wide common-mode input range down to the negative rail.
Technical Context
The TLV2262QDR employs Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω) and ultra-low input bias current (1 pA typ). Its rail-to-rail output stage enables full dynamic range utilization in 3-V systems, while the input common-mode range extends to the negative rail-critical for single-supply transducer interfaces.
It features internal compensation for unity-gain stability with 0.67 MHz gain-bandwidth product (at VDD = 3 V), 0.35–0.55 V/µs slew rate, and 55° phase margin into 50 kΩ || 100 pF loads-supporting stable closed-loop operation in sensor front-ends and active filters without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - supports direct integration into 3.3-V and 5-V industrial and automotive systems without level-shifting. |
| Input Offset Voltage | 950 µV max at TA = 25°C (TLV2262AQ variant) - enables accurate DC-coupled amplification of mV-level sensor signals. |
| Input Bias Current | 1 pA typ at TA = 25°C - preserves signal integrity when driving from high-impedance sources like piezoelectric elements. |
| Output Swing | Rail-to-rail - delivers full 0 V to VDD output range, maximizing SNR when driving SAR or delta-sigma ADCs. |
| Supply Current | 500 µA max per amplifier - allows dual-channel operation in space-constrained, battery-powered equipment with <1 mW total quiescent power. |
| Input Voltage Noise | 12 nV/√Hz at f = 1 kHz - ensures low-noise amplification of weak analog signals without degrading system resolution. |
| Common-Mode Input Range | Includes negative rail (VDD−) - permits direct connection of grounded-referenced sensors without biasing networks. |
Pinout & Package
TLV2262QDR is housed in an 8-pin SOIC (D) package with exposed pad (RoHS-compliant, lead-free, tape-and-reel). Pin 1 is marked by a beveled corner or dot; device orientation follows TI standard SOIC top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to ±50 mA; rail-to-rail swing enables direct interface with 3-V ADC reference rails. |
| 2 | IN− A | Inverting input of Amp A - high-impedance node (10¹² Ω); sensitive to PCB leakage; requires guard ring in high-Z designs. |
| 3 | IN+ A | Non-inverting input of Amp A - same impedance as IN−; accepts common-mode voltages from VDD− to VDD+ −1.3 V. |
| 4 | GND / VDD− | Negative supply terminal - serves as circuit ground reference; must be low-impedance path to minimize noise coupling. |
| 5 | VDD+ | Positive supply terminal - accepts 2.7–8 V; bypass capacitor (0.1 µF ceramic) required within 5 mm for stability. |
| 6 | OUT B | Amplifier B output - independent channel; identical specs to OUT A; supports dual-sensor or differential drive configurations. |
| 7 | IN− B | Inverting input of Amp B - electrically isolated from Amp A inputs; enables true dual-channel operation without crosstalk. |
| 8 | IN+ B | Non-inverting input of Amp B - matches IN+ A characteristics; supports matched gain stages in instrumentation topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers full 0 V to VDD swing - eliminates need for dual supplies when driving unipolar ADCs or DACs. |
| Low input bias current | 1 pA typical - prevents signal attenuation and DC error in >1 GΩ source impedances (e.g., pH electrodes, piezo sensors). |
| Low-noise performance | 12 nV/√Hz at 1 kHz - maintains ENOB in 12–14-bit data acquisition systems without additional filtering. |
| Automotive-grade qualification | Q-temp rated (−40°C to 125°C) - qualified per AEC-Q100; suitable for under-hood and ADAS sensor signal chains. |
| Single-supply operation | Common-mode input includes VDD− - enables direct connection of grounded transducers without input bias resistors or level shifters. |

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 |
|---|---|---|---|
| TLV2262IDR | Commercial temperature range (0°C to 70°C); 2.5 mV max VIO vs. 950 µV for TLV2262QDR | Not qualified for automotive or extended-temperature industrial use | Select TLV2262IDR only for cost-sensitive consumer applications where ambient stays below 70°C and offset <2.5 mV is acceptable. |
| OPA2333AIDR | Zero-drift architecture; 2 µV max VIO, 0.02 µV/°C drift; higher supply current (17 µA per amp) | Better DC precision but higher power; not rail-to-rail input | Choose OPA2333AIDR when microvolt-level DC accuracy is mandatory and supply current budget allows >30× increase over TLV2262QDR. |
Compared with TLV2262IDR, TLV2262QDR provides tighter offset and automotive qualification; compared with OPA2333AIDR, it trades zero-drift precision for 30× lower quiescent current and rail-to-rail input capability-making TLV2262QDR optimal for battery-powered, wide-temperature, moderate-precision sensor interfaces.

FAQ
What is the operating temperature range for TLV2262QDR?
The TLV2262QDR is qualified for operation from −40°C to 125°C and meets AEC-Q100 Grade 2 requirements. This extended temperature range is verified per TI's Q-temp automotive qualification program and supports deployment in engine bay, transmission control, and ADAS subsystems where ambient extremes are expected. The TLV2262QDR maintains specified electrical performance-including 950 µV max input offset voltage and 500 µA max supply current-across this full range.
Does TLV2262QDR support single-supply operation with input referenced to ground?
Yes, TLV2262QDR fully supports single-supply operation with inputs referenced to ground. Its common-mode input voltage range includes the negative rail (VDD−), allowing direct connection of grounded sensors such as piezoelectric elements or bridge transducers without external biasing. At VDD = 3 V, the valid input range extends from 0 V to 1.7 V; at VDD = 5 V, it spans 0 V to 3.5 V. This feature simplifies front-end design and reduces component count in TLV2262QDR-based systems.
What is the maximum output current capability of TLV2262QDR?
The TLV2262QDR can source or sink up to ±50 mA per amplifier output, as defined in its Absolute Maximum Ratings. However, for reliable operation within specifications, the recommended continuous output current is ±20 mA under typical thermal conditions. Output current capability is load-dependent and decreases as output voltage approaches the rails due to internal headroom limitations. For sustained ±50 mA loads, board-level thermal management (e.g., copper pour, airflow) is required to maintain junction temperature within limits. The TLV2262QDR datasheet specifies VOH and VOL performance at ±100 µA, ±500 µA, and ±1 mA test currents.
Is TLV2262QDR pin-compatible with other devices in the TLV226x family?
Yes, TLV2262QDR is pin-compatible with all TLV2262 variants in the SOIC-8 (D) package, including TLV2262CDR, TLV2262AIDR, and TLV2262IDR. Pin assignments (1–8) and electrical behavior are identical across these variants; only temperature grade, input offset voltage specification, and qualification status differ. This allows drop-in replacement during design iteration or qualification upgrades without PCB changes. Note that TLV2264 quad variants use different pinouts and are not pin-compatible with TLV2262QDR.
What decoupling capacitance is recommended for TLV2262QDR?
Texas Instruments recommends a 0.1 µF ceramic capacitor placed as close as possible (<5 mm) to the VDD+ (Pin 5) and GND (Pin 4) pins of TLV2262QDR. For systems with noisy power rails or high-frequency switching nearby, adding a parallel 1–10 µF tantalum or aluminum electrolytic capacitor improves low-frequency PSRR. The TLV2262QDR's internal compensation is optimized for this configuration; omitting the 0.1 µF cap may cause instability or increased output noise. Layout best practices-short traces, solid ground plane, and avoiding vias under the capacitor-apply directly to TLV2262QDR designs.
