Product details
Overview
TLV2262IPWLE from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage, low-power 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 across 2.7 V to 8 V operation. Its rail-to-rail output swing and common-mode input range extending to the negative rail make it ideal for interfacing with 3-V ADCs in battery-powered sensor signal conditioning.
For engineers reviewing the TLV2262IPWLE datasheet, TLV2262IPWLE pinout, TLV2262IPWLE application, or TLV2262IPWLE equivalent, this device is selected for precision analog front-ends requiring low-noise amplification of high-impedance sources (e.g., piezoelectric transducers), single-supply operation down to 2.7 V, and guaranteed performance over –40°C to +85°C.
Technical Context
The TLV2262IPWLE uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise. Its input stage supports common-mode voltages down to the negative rail, enabling true single-supply operation without level-shifting circuitry.
It features a gain-bandwidth product of 0.67 MHz at 3 V and 0.71 MHz at 5 V, with 5.6 µs settling time to 0.1% for a 1-V step, and phase margin of 55°-enabling stable unity-gain buffer and active filter configurations without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - Enables direct operation from single Li-ion cells or regulated 3.3-V/5-V rails. |
| Input Bias Current | 1 pA typ - Preserves signal integrity when amplifying from ultra-high-impedance sensors (e.g., pH electrodes, photodiodes). |
| Input Voltage Noise | 12 nV/√Hz @ 1 kHz - Supports low-noise amplification of microvolt-level signals without significant SNR degradation. |
| Output Swing | Rail-to-rail - Delivers full dynamic range into ADCs with 0–3 V or 0–5 V input ranges, maximizing resolution utilization. |
| Quiescent Current | 500 µA max per amplifier - Allows dual-channel operation in handheld devices with multi-year battery life. |
| Input Offset Voltage | 2.5 mV max (TLV2262I grade) - Suitable for moderate-precision applications like industrial sensor buffering without trimming. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - Drives loads up to ±50 mA; rail-to-rail swing ensures full-scale ADC interface. |
| 2 | IN1– | Inverting input - High-impedance node (10¹² Ω); sensitive to PCB leakage and layout parasitics. |
| 3 | IN1+ | Non-inverting input - Common-mode range includes VDD– (GND); enables ground-referenced sensing. |
| 4 | VDD– / GND | Negative supply / ground reference - Shared return path for both amplifiers; requires low-impedance local decoupling. |

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 |
|---|---|---|---|
| TLV2262AIPWLE | 950 µV max input offset voltage (vs. 2.5 mV for TLV2262IPWLE); otherwise identical specs and pinout. | Required for higher-precision DC-coupled applications (e.g., precision weight scales) where offset drift impacts accuracy. | Select TLV2262AIPWLE when <1 mV VIO is mandatory; same footprint and layout, no redesign needed. |
| MCP6022-I/SN | Higher 10 µV max VIO but lower 8.5 nV/√Hz noise; 170 µA supply current; 10 MHz GBW; operates down to 2.7 V. | Better suited for wideband AC-coupled applications (e.g., ultrasonic receiver front-ends) where speed outweighs DC precision. | Choose MCP6022-I/SN when bandwidth >1 MHz is required and lower power is secondary; verify stability with capacitive loads. |
Compared with TLV2262AIPWLE, the TLV2262IPWLE trades DC precision for cost and availability; compared with MCP6022-I/SN, it offers superior DC performance and rail-to-rail input capability but lower bandwidth-making it optimal for precision, low-speed, low-power industrial sensing.

FAQ
What is the operating temperature range for TLV2262IPWLE?
The TLV2262IPWLE is rated for operation from –40°C to +85°C, meeting industrial temperature requirements. This range is explicitly specified in the "recommended operating conditions" table of the SLOS186A datasheet for the 'I' suffix variant, and confirmed by the packaging option TLV2262IPWLE listed under the –40°C to 85°C row in the device options table.
Does TLV2262IPWLE support true rail-to-rail input?
No, TLV2262IPWLE does not feature 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+) at 3 V supply-i.e., 0 V to 1.7 V. This is clearly defined in the "recommended operating conditions" table. Only the output is rail-to-rail.
What is the maximum supply current for TLV2262IPWLE?
The maximum supply current for TLV2262IPWLE is 500 µA per amplifier, totaling 1 mA for both channels. This value is specified in the "electrical characteristics" tables for VDD = 3 V and VDD = 5 V under the IDD parameter, with "MAX" column listing 500 µA at TA = 25°C and full range.
Can TLV2262IPWLE drive a 10-kΩ load to rail in single-supply mode?
Yes, TLV2262IPWLE can drive a 10-kΩ load to within 10 mV of both rails under typical conditions. The datasheet specifies VOH ≥ 2.99 V and VOL ≤ 10 mV at VDD = 3 V, IOH/IOL = 20 µA - well within capability for a 10-kΩ load (300 µA max current). Performance degrades only under heavy loads (>1 mA), where VOL rises to 300 mV.
Is TLV2262IPWLE pin-compatible with TLV2262CD or TLV2262CP?
Yes, TLV2262IPWLE is pin-compatible with TLV2262CD (SOIC-8) and TLV2262CP (PDIP-8), as all share the same dual-amplifier TSSOP/SOIC/PDIP pinout: OUT1, IN1–, IN1+, GND, VDD+, OUT2, IN2–, IN2+. This is confirmed by the "TLV2262C, TLV2262AC / TLV2262I, TLV2262AI / TLV2262Q, TLV2262AQ D, P, OR PW PACKAGE (TOP VIEW)" diagram on page 3 of SLOS186A.
