Product details
Overview
TLV2254AID from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-voltage, micropower applications. It delivers 19 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 850 µV maximum input offset voltage at 25°C, operating from 2.7 V to 8 V supply. It is used in precision signal conditioning for high-impedance piezoelectric transducers and battery-powered remote sensing.
For engineers reviewing the TLV2254AID datasheet, TLV2254AID pinout, TLV2254AID application, or TLV2254AID equivalent, key selection criteria include rail-to-rail output swing, sub-34 µA per-channel quiescent current, guaranteed 850 µV VIO max, and compatibility with 3 V ADC interfaces in space-constrained industrial monitoring systems.
Technical Context
The TLV2254AID employs Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining ultra-low input bias current (1 pA typ) and low noise (19 nV/√Hz). Its input stage operates with common-mode voltage range extending to the negative rail, enabling single-supply operation down to 2.7 V.
It is fully characterized across −40°C to 125°C and specified for both single- and split-supply configurations. The device features 1012 Ω differential and common-mode input resistance, 0.187 MHz gain-bandwidth product, and 63° phase margin - ensuring stable unity-gain operation with capacitive loads up to 100 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - supports direct integration into 3 V and 5 V battery-powered systems without level-shifting. |
| Input Offset Voltage | ≤850 µV max at 25°C - enables accurate DC-coupled amplification in sensor front-ends without trimming. |
| Quiescent Current | 34 µA per channel typ - allows four independent amplifiers to operate continuously on microampere-scale power budgets. |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - critical for preserving SNR in low-level analog signal chains (e.g., piezo sensors). |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs with 0–3 V or 0–5 V input ranges, maximizing resolution utilization. |
| Input Bias Current | 1 pA typ - minimizes voltage error across high-impedance sources (>1 MΩ), such as pH electrodes or photodiode TIA feedback networks. |
| Gain-Bandwidth Product | 0.187 MHz - sufficient for anti-aliasing filtering and sensor buffering up to ~100 kHz with stable phase margin. |
Pinout & Package
TLV2254AID is housed in an 14-pin SOIC (D) package with standard pin spacing (1.27 mm), surface-mount compatible, and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives external load or next-stage input; rail-to-rail capable. |
| 2 | IN−1 | Inverting input of Amp 1 - high-impedance node; sensitive to PCB leakage and guarding requirements. |
| 3 | IN+1 | Non-inverting input of Amp 1 - accepts reference or sensor signal; common-mode range includes GND. |
| 4 | GND / VDD− | Negative supply terminal - serves as reference for all four amplifiers; must be low-impedance. |
| 5 | IN+2 | Non-inverting input of Amp 2 - electrically isolated from Amp 1 inputs; enables dual-sensor parallel processing. |
| 6 | IN−2 | Inverting input of Amp 2 - matched performance to Pin 2; supports differential or single-ended configurations. |
| 7 | OUT2 | Amplifier 2 output - independent output path; no internal crosstalk with OUT1 under normal operation. |
| 8 | VDD+ | Positive supply terminal - powers all four amplifiers; decoupling capacitor required at pin. |
| 9 | OUT3 | Amplifier 3 output - identical electrical specs to OUT1/OUT2; enables three-channel signal conditioning. |
| 10 | IN−3 | Inverting input of Amp 3 - shares same process characteristics as Pins 2 and 6; supports matched multi-channel designs. |
| 11 | IN+3 | Non-inverting input of Amp 3 - referenced to same GND; maintains rail-to-rail input capability. |
| 12 | IN+4 | Non-inverting input of Amp 4 - completes quad configuration; allows simultaneous conditioning of four analog signals. |
| 13 | IN−4 | Inverting input of Amp 4 - fully specified over temperature; supports precision instrumentation-grade layouts. |
| 14 | OUT4 | Amplifier 4 output - final output in quad set; verified rail-to-rail swing and load drive up to ±50 mA. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2254ID | Same architecture but 1500 µV max VIO at 25°C vs. 850 µV for TLV2254AID; otherwise identical pinout, specs, and package. | Suitable for cost-sensitive, non-precision applications where offset drift tolerance exceeds ±2 mV. | Select TLV2254ID only when VIO budget allows ≥1.5× higher error than TLV2254AID. |
| OPA2333AIDR | Zero-drift architecture; 2 µV max VIO, 0.1 µV/°C drift, but 17 µA per channel - lower noise (0.7 µVPP) and higher cost. | Better for DC-critical applications (e.g., precision weigh scales) requiring <10 µV total offset error over temperature. | Choose OPA2333AIDR only when long-term DC stability outweighs micropower needs and BOM cost sensitivity. |
Compared with TLV2254ID, TLV2254AID provides tighter offset control for sensor linearity; compared with OPA2333AIDR, it trades zero-drift precision for 2× lower quiescent current and lower unit cost in volume production.

FAQ
What is the maximum input offset voltage specification for TLV2254AID at 25°C?
The TLV2254AID has a maximum input offset voltage of 850 µV at 25°C, as specified in the "TLV2254AI" column of the electrical characteristics tables. This value is guaranteed across production lots and forms the basis for precision DC-coupled design margins in sensor interface circuits using TLV2254AID.
Does TLV2254AID support true rail-to-rail output swing with a 3 V supply?
Yes, TLV2254AID delivers rail-to-rail output swing - meaning its output can reach within millivolts of both VDD+ and GND - when operated from a 3 V supply. At 25°C and IOH = −20 µA, VOH = 2.98 V; at IOL = 50 µA, VOL = 10 mV, confirming full dynamic range utilization in TLV2254AID-based 3 V systems.
What is the typical supply current per channel for TLV2254AID at 3 V operation?
The typical supply current per channel for TLV2254AID is 34 µA at 3 V and 25°C, as stated in the datasheet's "Supply current" parameter table. Total quiescent current for all four amplifiers is therefore approximately 136 µA - enabling multi-year operation on small Li-MnO₂ or CR2032 batteries in always-on sensor nodes using TLV2254AID.
Is TLV2254AID qualified for automotive applications?
No, TLV2254AID is not automotive-qualified. It carries the 'I' temperature suffix (−40°C to 125°C), which meets industrial grade requirements but lacks AEC-Q100 qualification. For automotive use, the TLV2254AQD variant - explicitly listed in the "Q" automotive option table - is the qualified version of TLV2254AID with identical electrical specs and enhanced process controls.
Which package type does TLV2254AID use, and is it lead-free?
TLV2254AID uses the 14-pin SOIC (D) package, as confirmed in the "TLV2254 AVAILABLE OPTIONS" table. It is RoHS-compliant and lead-free, consistent with Texas Instruments' green packaging standards effective since the 2006 revision date of the SLOS185D datasheet, and suitable for modern automated SMT assembly processes handling TLV2254AID.
