Product details
Overview
TLV2262IP from Texas Instruments is a dual rail-to-rail output CMOS 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 supply range. Its common-mode input voltage includes the negative rail and supports single-supply interfacing with precision ADCs in portable instrumentation.
For engineers reviewing the TLV2262IP datasheet, TLV2262IP pinout, TLV2262IP application, or TLV2262IP equivalent, key selection criteria include its 950 µV max input offset voltage (A-grade), rail-to-rail output swing, low-noise performance at 3 V operation, and compatibility with high-impedance piezoelectric sensor conditioning circuits.
Technical Context
The TLV2262IP uses Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω) and low input bias current while maintaining rail-to-rail output capability. Its architecture supports both single-supply (2.7–8 V) and split-supply operation without performance degradation.
It features fully characterized AC performance at 3 V and 5 V, including 0.67 MHz gain-bandwidth product, 0.35–0.55 V/µs slew rate, and 65–77 dB CMRR over −40°C to +125°C. Input common-mode range extends to VDD−, enabling ground-referenced signal acquisition.
Key Specifications

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 |
|---|---|---|---|
| TLV2262AIP | Same package and pinout; tighter 950 µV max VIO (vs. 2.5 mV for TLV2262IP) at 25°C. | Required for higher-precision DC applications where offset drift must be minimized. | Select TLV2262AIP when VIO ≤ 950 µV is mandatory; TLV2262IP remains suitable for cost-sensitive, moderate-accuracy designs. |
| TLV2332IP | Legacy dual op-amp with 3 mV max VIO, higher 1.2 mA supply current, and no rail-to-rail output. | Limited dynamic range in single-supply 3 V systems; unsuitable for precision ADC drive. | TLV2262IP offers superior noise, power, and output swing - upgrade recommended unless legacy footprint lock-in applies. |
Compared with TLV2262AIP, TLV2262IP trades guaranteed low offset for lower cost and broader availability; compared with TLV2332IP, it delivers 58% lower supply current, rail-to-rail output, and 2× lower input noise - making it the preferred choice for modern low-power, high-fidelity analog front-ends.

FAQ
What is the maximum operating temperature range for TLV2262IP?
The TLV2262IP is rated for operation from −40°C to +125°C, validated across its full electrical specification range. This makes it suitable for under-hood automotive and industrial control applications where ambient temperatures exceed standard commercial grade limits. All key parameters - including input offset voltage, CMRR, and supply current - are guaranteed across this full range per the datasheet's "recommended operating conditions" table.
Does TLV2262IP support true single-supply operation with inputs referenced to ground?
Yes, TLV2262IP supports true single-supply operation: its common-mode input voltage range includes the negative rail (VDD−/GND), allowing inputs to be referenced directly to ground. This enables DC-coupled configurations such as non-inverting amplifiers with ground-referenced sensors, without requiring input biasing networks that degrade noise or accuracy.
How does the rail-to-rail output capability of TLV2262IP improve ADC interface performance?
The rail-to-rail output of TLV2262IP delivers full-scale swing from near VDD− to near VDD+, maximizing usable voltage range when driving ADCs. For example, at 3.3 V supply, it achieves >3.2 V peak-to-peak output - increasing effective resolution by up to 0.5 bits versus conventional op-amps with 1.2 V headroom loss, especially critical for 12–16 bit SAR and sigma-delta converters.
Is TLV2262IP pin-compatible with other members of the TLV226x family?
Yes, TLV2262IP shares identical 8-pin DIP pinout with all TLV2262x variants (e.g., TLV2262CD, TLV2262AIP, TLV2262QD). Pin functions - including dual amplifier inputs/outputs, shared VDD+ and GND - are consistent across temperature grades and offset grades, enabling drop-in replacement within the same package footprint.
What is the typical input voltage noise density of TLV2262IP and at what frequency is it specified?
The TLV2262IP exhibits 12 nV/√Hz typical input voltage noise density at f = 1 kHz, as measured and guaranteed in the datasheet's electrical characteristics tables. This value is representative of mid-band noise performance and remains stable across the 10 Hz–10 kHz range, supporting accurate low-frequency sensor signal amplification without excessive filtering overhead.
