Product details
Overview
TLV2241TDR from Texas Instruments is a single-channel micropower rail-to-rail input/output operational amplifier in 5-pin SOT-23 package, delivering 1 µA/channel supply current, 5.5 kHz gain bandwidth product, and 600 µV typical input offset voltage at 2.7 V. It operates from 2.5 V to 12 V and supports industrial temperature range (–40°C to 125°C), making it suitable for ultra-low-power sensor front-ends and battery-powered instrumentation.
For engineers reviewing the TLV2241TDR datasheet, TLV2241TDR pinout, TLV2241TDR application, or TLV2241TDR equivalent, key selection criteria include its rail-to-rail I/O capability at sub-1-µA quiescent current, guaranteed operation down to 2.5 V for Li-ion compatibility, and validated performance across 2.7 V/5 V/12 V supply points with full industrial temperature specification.
Technical Context
The TLV2241TDR employs CMOS input stage architecture enabling femtoampere-level input bias currents (100–500 pA) and high input impedance (>300 MΩ), critical for interfacing with high-impedance sensors and megaohm-scale feedback networks. Its rail-to-rail output swing delivers >2.65 V high-level and <230 mV low-level output voltage at 2.7 V supply, ensuring full dynamic range utilization in single-supply systems.
Designed for stability with capacitive loads up to 100 pF, the device features 60° phase margin and 15 dB gain margin under standard test conditions (RL = 500 kΩ, CL = 100 pF). Its 2 V/ms slew rate and 1.84 ms 0.1% settling time support precision DC-coupled signal conditioning without high-frequency artifacts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2401IDBVR | 0.88 µA supply current, 5 kHz GBW, 390 µV VIO - lower offset but slightly reduced bandwidth vs TLV2241TDR | Optimized for higher-precision DC measurement where <400 µV offset is mandatory | Select when offset voltage is primary constraint and 5 kHz bandwidth suffices |

FAQ
What is the maximum supply voltage for TLV2241TDR?
The absolute maximum supply voltage for TLV2241TDR is 16.5 V, but the recommended operating range is 2.5 V to 12 V. Operation above 12 V is not characterized and may compromise parametric guarantees or long-term reliability. All electrical specifications for TLV2241TDR are validated at 2.7 V, 5 V, and 12 V supply points across temperature.
Does TLV2241TDR support rail-to-rail output at 2.5 V supply?
Yes, TLV2241TDR maintains rail-to-rail output capability down to 2.5 V supply. At 2.7 V, it delivers VOH ≥ 2.65 V and VOL ≤ 230 mV with 50 µA load, confirming usable swing within 150 mV of both rails. This behavior is verified across the full industrial temperature range (–40°C to 125°C), ensuring consistent performance in low-voltage battery applications.
What is the input bias current specification for TLV2241TDR?
TLV2241TDR exhibits an input bias current of 100 pA typical at 25°C (up to 550 pA over full industrial temperature range). This ultra-low value enables accurate amplification of signals from high-impedance sources such as pH electrodes, photodiodes, and thermistors without introducing significant offset error due to bias current flow through feedback resistors.
Can TLV2241TDR drive capacitive loads without oscillation?
Yes, TLV2241TDR is stable with capacitive loads up to 100 pF, demonstrated by 60° phase margin and 15 dB gain margin under standard test conditions (RL = 500 kΩ, CL = 100 pF). This eliminates the need for series isolation resistors when interfacing with ADC input capacitors or RC anti-aliasing filters, simplifying layout and preserving signal integrity.
Is TLV2241TDR qualified for automotive applications?
TLV2241TDR is not AEC-Q200 qualified, but its industrial temperature rating (–40°C to 125°C), 12 V max supply, and robust ESD performance (2 kV HBM) make it suitable for non-safety-critical automotive cabin applications such as climate control sensors, infotainment system interfaces, and body electronics-provided system-level qualification is performed per OEM requirements.
