Product details
Overview
TLV2254AIPW 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 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 ADC drivers.
For engineers reviewing the TLV2254AIPW datasheet, TLV2254AIPW pinout, TLV2254AIPW application, or TLV2254AIPW equivalent, key selection criteria include its rail-to-rail output swing, 850 µV maximum input offset voltage (A-grade), TSSOP-14 package footprint, and guaranteed operation from −40°C to +125°C for industrial and automotive sensing systems.
Technical Context
The TLV2254AIPW implements a CMOS-input, rail-to-rail output amplifier architecture with high-impedance inputs (10¹² Ω differential and common-mode resistance) and low-noise transconductance stages. Its design supports single-supply operation down to 2.7 V while maintaining full output swing from VDD− to VDD+.
It features internal ESD protection, operates over an extended temperature range (−40°C to 125°C), and is characterized for both 3 V and 5 V supplies - making it suitable for portable instrumentation where power efficiency and dynamic range are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - enables direct use with Li-ion, 3.3 V, and 5 V rails without level-shifting. |
| Input Offset Voltage (Max) | 850 µV at TA = 25°C - ensures ≤0.085% gain error in 1 V full-scale precision amplification. |
| Supply Current per Channel | 34 µA typ - allows four independent amplifiers to operate on <140 µA total, ideal for ultra-low-power wake-up circuits. |
| Input Voltage Noise | 19 nV/√Hz at f = 1 kHz - supports accurate amplification of microvolt-level signals from piezoelectric or thermopile sensors. |
| Input Bias Current | 1 pA typ - minimizes voltage error across high-impedance sources (>1 GΩ), such as pH electrodes or photodiode transimpedance nodes. |
| Output Swing | Rail-to-rail - delivers full 0 V to VDD output range, maximizing ADC utilization and eliminating need for negative supply. |
| Gain-Bandwidth Product | 0.187 MHz at VDD = 3 V - supports stable unity-gain buffering up to ~180 kHz for anti-aliasing and sensor signal chain filtering. |
Pinout & Package
TSSOP-14 package (PW suffix), 5.0 mm × 4.4 mm body, 0.65 mm pitch, exposed pad optional (not electrically connected in standard variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to ±50 mA; rail-to-rail swing referenced to VDD−/GND. |
| 2 | IN− A | Inverting input of Amp A - high-impedance CMOS node; requires matched trace impedance for optimal CMRR. |
| 3 | IN+ A | Non-inverting input of Amp A - accepts common-mode voltage from VDD− to (VDD+ −1.3 V) at 3 V supply. |
| 4 | VDD−/GND | Power ground reference - must be low-impedance plane; shared return for all four amplifiers. |
| 5 | IN+ B | Non-inverting input of Amp B - electrically isolated from other channels; supports independent sensor biasing. |
| 6 | IN− B | Inverting input of Amp B - symmetrical layout recommended to match Amp A for dual-channel matched gain blocks. |
| 7 | OUT B | Amplifier B output - identical drive capability and rail-to-rail behavior as OUT A. |
| 8 | VDD+ | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability. |
| 9 | OUT C | Amplifier C output - fully independent channel; no crosstalk specified beyond typical 80 dB at 1 kHz. |
| 10 | IN− C | Inverting input of Amp C - same input structure and bias current as other channels. |
| 11 | IN+ C | Non-inverting input of Amp C - supports DC-coupled high-impedance source interfacing. |
| 12 | VDD−/GND | Second ground connection - tied internally to Pin 4; improves thermal dissipation and reduces ground bounce. |
| 13 | IN+ D | Non-inverting input of Amp D - enables four-channel simultaneous acquisition in data loggers. |
| 14 | IN− D | Inverting input of Amp D - layout symmetry with Pins 2/6/10 recommended for matching. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2254IPW | Higher 1500 µV max input offset voltage (non-A grade); otherwise identical electrical specs and pinout. | Suitable for cost-sensitive, non-precision applications where calibration is performed externally. | Select TLV2254IPW if system-level trimming compensates for higher VIO and budget constraints dominate. |
| MCP6004-E/ST | Higher 100 µA/channel supply current; 25 µV max VIO; 6 MHz GBW; same TSSOP-14 package. | Better DC precision and bandwidth but consumes ~3× more power - unsuitable for multi-year battery life. | Choose MCP6004-E/ST only when higher speed and lower offset outweigh micropower requirements. |
Compared with TLV2254IPW, the TLV2254AIPW offers tighter input offset tolerance for reduced calibration burden, while the MCP6004-E/ST trades 3× higher supply current for 30× lower offset and 32× higher bandwidth - making TLV2254AIPW optimal for ultra-low-power, moderate-bandwidth sensor interfaces.

FAQ
What is the maximum operating temperature range for the TLV2254AIPW?
The TLV2254AIPW is rated for continuous operation from −40°C to +125°C, meeting industrial and automotive under-hood requirements. This range is validated per the device's recommended operating conditions and absolute maximum ratings, with full electrical characterization across the entire span at both 3 V and 5 V supplies.
Does the TLV2254AIPW support true rail-to-rail input common-mode range?
No, the TLV2254AIPW supports rail-to-rail *output* swing but not rail-to-rail *input*. Its common-mode input voltage range extends to the negative rail (VDD−/GND) but only up to (VDD+ −1.3 V) at 3 V supply - meaning it accepts inputs from 0 V to 1.7 V, not the full 0 V to 3 V range.
How does the 850 µV maximum input offset voltage of the TLV2254AIPW impact precision designs?
The 850 µV maximum input offset voltage (at TA = 25°C) limits worst-case DC gain error to ±0.085% in a 1 V full-scale system. For higher-accuracy applications, this value may require one-time factory calibration or system-level software correction - especially when used in closed-loop transducer interfaces or high-resolution ADC driver stages.
Can the TLV2254AIPW drive capacitive loads directly, such as ADC input sampling capacitors?
The TLV2254AIPW is stable with capacitive loads up to 100 pF when configured for unity gain, as verified by phase margin (63°) and gain margin (15 dB) measurements. For larger capacitive loads (e.g., >200 pF), an isolation resistor (10–100 Ω) between the amplifier output and the load is recommended to maintain stability.
Is the TLV2254AIPW pin-compatible with earlier-generation TI quad op-amps like the TLV2324?
Yes, the TLV2254AIPW shares identical pinout and footprint with the TLV2324 in TSSOP-14 packaging. However, it offers improved specifications: lower noise (19 nV/√Hz vs. 35 nV/√Hz), lower input offset (850 µV vs. 2000 µV), and rail-to-rail output - making it a functional upgrade without PCB redesign.
