Product details
Overview
TLV2254AIN from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-voltage, micropower operation. It delivers 19 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 34 µA per channel supply current across a 2.7 V to 8 V supply range-enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2254AIN datasheet, TLV2254AIN pinout, TLV2254AIN application, or TLV2254AIN equivalent, this device is selected for ultra-low-power analog front-ends where rail-to-rail output swing, high input impedance, and sub-1 mV input offset voltage are critical in single-supply 3 V systems.
Technical Context
The TLV2254AIN uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input bias current (1 pA typ) and low noise (19 nV/√Hz). Its common-mode input voltage range extends to the negative rail, supporting true single-supply operation down to 2.7 V.
It is fully characterized over −40°C to +125°C and specified for both single- and split-supply configurations. The 850 µV maximum input offset voltage (TLV2254AI variant) and 0.5 µV/°C temperature coefficient support stable DC-coupled amplification in precision measurement paths without external trimming.
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 (Max) | 850 µV at TA = 25°C - enables accurate DC amplification in sensor bridges and thermocouple interfaces. |
| Input Bias Current (Typ) | 1 pA - preserves signal integrity when amplifying high-impedance sources like piezoelectric transducers. |
| Supply Current (Per Channel) | 34 µA typ - allows four independent amplifiers to operate continuously on microampere-scale power budgets. |
| Input Voltage Noise | 19 nV/√Hz at f = 1 kHz - provides superior SNR for low-frequency sensor signal conditioning versus prior micropower op amps. |
| Output Swing | Rail-to-rail - maximizes dynamic range when driving ADCs with 3 V reference voltages. |
| Common-Mode Input Range | Includes negative rail - permits direct connection of sensors referenced to ground in single-supply topologies. |
Pinout & Package
TLV2254AIN is housed in a 14-pin plastic DIP (N) package with through-hole mounting and industry-standard pin spacing. This package supports manual prototyping, legacy board designs, and high-reliability industrial applications requiring mechanical robustness and thermal stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to ±50 mA with rail-to-rail swing. |
| 2 | IN− A | Inverting input of Amplifier A - high-impedance node (10¹² Ω) for feedback network connection. |
| 3 | IN+ A | Non-inverting input of Amplifier A - accepts signals from high-Z sources with minimal loading. |
| 4 | GND / VDD− | Negative supply terminal - serves as reference for single-supply operation or negative rail in split-supply mode. |

| 6 | IN− B | Inverting input of Amplifier B - used for differential or inverting gain configurations. |
| 7 | OUT B | Amplifier B output - identical performance to OUT A; no crosstalk between channels. |
| 8 | VDD+ | Positive supply terminal - accepts 2.7–8 V; supplies all four amplifiers internally. |
| 9 | OUT C | Amplifier C output - fully independent output stage with same rail-to-rail capability. |
| 10 | IN− C | Inverting input of Amplifier C - matches electrical specs of pins 2 and 6. |
| 11 | IN+ C | Non-inverting input of Amplifier C - supports multi-channel sensor signal routing. |
| 12 | GND / VDD− | Shared negative supply - internal connection to pin 4; must be tied to system ground. |
| 13 | IN+ D | Non-inverting input of Amplifier D - completes quad-channel set for parallel processing. |
| 14 | OUT D | Amplifier D output - enables simultaneous conditioning of four analog signals without multiplexing delay. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2254AIP | Same electrical specs but in 14-pin plastic DIP (P) package - wider body, different lead pitch and footprint. | Designed for PCBs with legacy P-package land patterns; not interchangeable with N-package without layout change. | Select TLV2254AIP only when matching existing P-package footprints; TLV2254AIN requires N-package layout. |
| TLV2434CDR | Higher supply current (550 µA/channel), wider supply range (2.7–16 V), no rail-to-rail output - 1.5 V headroom required. | Suitable for higher-drive applications needing >50 mA output or operation above 8 V; incompatible for rail-to-rail 3 V systems. | Choose TLV2434CDR only when output drive >50 mA or supply >8 V is required; TLV2254AIN remains optimal for ultra-low-power rail-to-rail use cases. |
Compared with TLV2254AIP, TLV2254AIN offers identical performance in a narrower-body DIP package compatible with space-constrained layouts; compared with TLV2434CDR, it trades output drive and voltage range for 16× lower quiescent current and true rail-to-rail operation essential for 3 V precision sensing.

FAQ
What is the maximum operating temperature range for the TLV2254AIN?
The TLV2254AIN is rated for operation from −40°C to +125°C, making it suitable for under-hood automotive, industrial control, and outdoor environmental monitoring applications where wide thermal margins are required. This rating is confirmed in the Absolute Maximum Ratings table and Operating Conditions section of the SLOS185D datasheet.
Does the TLV2254AIN support single-supply operation at 3 V?
Yes, the TLV2254AIN is fully specified for single-supply operation from 2.7 V to 8 V, including 3 V. Its rail-to-rail output swing and common-mode input range extending to the negative rail allow full functionality with a single 3 V supply - verified in both electrical characteristics tables at VDD = 3 V and the Functional Description section.
What is the input offset voltage specification for TLV2254AIN?
The TLV2254AIN has a maximum input offset voltage of 850 µV at TA = 25°C and 1000 µV over the full −40°C to +125°C range. This value applies specifically to the 'AI' grade (as indicated by the 'A' suffix in TLV2254AIN), which is the precision variant of the TLV2254 family.
Can TLV2254AIN drive analog-to-digital converter (ADC) inputs directly?
Yes, the TLV2254AIN can directly drive ADC inputs due to its rail-to-rail output swing, low output impedance (220 Ω at 25 kHz), and ability to source/sink ±50 mA. When interfacing with SAR or delta-sigma ADCs operating from the same 3 V supply, it eliminates need for external buffers or level shifters - confirmed in the Applications section of the datasheet.
Is TLV2254AIN pin-compatible with other TLV2254 variants?
Yes, all TLV2254 variants-including TLV2254AIN, TLV2254AID, TLV2254AIP, and TLV2254AIPWLE-share identical pinouts across D, N, P, and PW packages. The 'N' suffix denotes the 14-pin plastic DIP package, and the pin configuration matches the standard quad op amp layout shown in Figure 3 of the SLOS185D datasheet.
