Product details
Overview
TLV2254AIPWR 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. Its common-mode input voltage includes the negative rail and supports single-supply interfacing with ADCs in portable instrumentation.
For engineers reviewing the TLV2254AIPWR datasheet, TLV2254AIPWR pinout, TLV2254AIPWR application, or TLV2254AIPWR equivalent, key selection criteria include rail-to-rail output swing, sub-1 pA input bias current, 850 µV max input offset voltage (A-grade), TSSOP-14 package compatibility, and guaranteed operation from −40°C to 125°C.
Technical Context
The TLV2254AIPWR uses Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω) and ultra-low input bias current while maintaining rail-to-rail output capability. Its architecture supports stable unity-gain operation with 63° phase margin and 15 dB gain margin under 50 kΩ//100 pF load conditions.
It is fully specified for both single-supply (2.7 V–8 V) and split-supply operation, with common-mode input range extending to the negative rail and output swing within 10 mV of both rails at light loads. Input offset voltage is trimmed to ≤850 µV at 25°C for the 'A' grade variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - Enables direct use with single-cell Li-ion, two-cell alkaline, or regulated 3.3 V/5 V rails. |
| Input Offset Voltage (Max) | 850 µV at TA = 25°C - Ensures <1 mV DC error in precision sensor signal conditioning without trimming. |
| Input Bias Current (Typ) | 1 pA - Critical for high-impedance sources like piezoelectric transducers or pH electrodes. |
| Input Voltage Noise | 19 nV/√Hz at f = 1 kHz - Four times lower than prior micropower CMOS op amps, improving SNR in low-level analog front-ends. |
| Quiescent Current | 34 µA per channel - Supports >1-year battery life in always-on remote sensors powered by CR2032 cells. |
| Output Swing | Rail-to-rail - Delivers full dynamic range into ADCs with 0–3.3 V or 0–5 V reference voltages. |
| Gain-Bandwidth Product | 0.187 MHz at VDD = 3 V - Sufficient for anti-aliasing filters, sensor amplification, and slow-control loops. |
Pinout & Package
TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, 14-terminal surface-mount, moisture sensitivity level 1 (MSL-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - Drives loads up to ±50 mA; swings within 10 mV of VDD+ and VDD−/GND. |
| 2 | IN− A | Inverting input of Amp A - High-impedance node (10¹² Ω); sensitive to PCB leakage and guarding requirements. |
| 3 | IN+ A | Non-inverting input of Amp A - Matches IN− A in bias current; requires matched trace impedance for best CMRR. |
| 4 | VDD−/GND | Negative supply or ground reference - Must be low-impedance; shared return path for all four amplifiers. |
| 5 | IN+ B | Non-inverting input of Amp B - Electrically isolated from other inputs; enables independent dual-channel configuration. |

| 10 | IN− C | Inverting input of Amp C - Matches IN− A/B; allows consistent feedback network design across all channels. |
| 11 | IN+ C | Non-inverting input of Amp C - Used for buffered reference generation or multi-sensor signal routing. |
| 12 | VDD+ | Positive supply - Accepts 2.7–8 V; bypass capacitor (0.1 µF) required within 2 mm of this pin. |
| 13 | IN+ D | Non-inverting input of Amp D - Enables fourth independent channel; supports quad-sensor systems or redundant monitoring. |
| 14 | IN− D | Inverting input of Amp D - Completes quad-channel set; all four amplifiers share same supply and thermal environment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2254IPWR | 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 in-system. | Select TLV2254IPWR when offset drift and initial accuracy are less critical than BOM cost reduction. |
| MCP6004T-I/ST | Higher 100 µA/channel supply current; 2.7 V–6.0 V supply range; 3 mV max VIO; 22 nV/√Hz noise. | Targeted at general-purpose consumer electronics rather than low-noise industrial sensing. | Choose MCP6004T-I/ST only if wider production volume, alternate packaging (SOIC-14), or Microchip ecosystem alignment outweighs noise and power penalties. |
Compared with TLV2254IPWR, the TLV2254AIPWR provides tighter initial offset for reduced calibration overhead; compared with MCP6004T-I/ST, it delivers 3× lower quiescent current and 15% lower noise-critical for battery longevity and weak-signal fidelity in measurement-class designs.

FAQ
What is the maximum operating temperature range for the TLV2254AIPWR?
The TLV2254AIPWR is rated for continuous operation from −40°C to +125°C ambient temperature. This specification is validated per the recommended operating conditions table in the official datasheet (SLOS185D), making it suitable for under-hood automotive, industrial control, and outdoor environmental monitoring applications where thermal robustness is essential. The device maintains its 850 µV max input offset voltage and rail-to-rail output performance across this full range.
Does the TLV2254AIPWR support true rail-to-rail input operation?
No, the TLV2254AIPWR does not support rail-to-rail input operation. Its common-mode input voltage range extends to the negative rail (VDD−/GND) but stops 1.3 V below the positive rail (VDD+) at VDD = 3 V or 5 V. For example, at 3 V supply, the usable input range is 0 V to 1.7 V. This limitation is explicitly defined in the "Recommended Operating Conditions" section of the datasheet and must be accounted for in circuit design to avoid clipping or increased distortion.
Can the TLV2254AIPWR drive capacitive loads directly?
The TLV2254AIPWR is stable driving up to 100 pF capacitive loads with 50 kΩ series resistance, as verified by phase margin (63°) and gain margin (15 dB) measurements in the datasheet. Driving larger capacitive loads (e.g., >200 pF) without isolation resistance may cause peaking or oscillation. For ADC input buffering or cable driving, a small series resistor (10–100 Ω) between the TLV2254AIPWR output and the capacitance is recommended to preserve stability.
Is the TLV2254AIPWR pin-compatible with the TLV2254IPWR?
Yes, the TLV2254AIPWR and TLV2254IPWR share identical TSSOP-14 (PW) package dimensions, pinout, and footprint. They differ only in electrical grading: the 'A' suffix denotes ≤850 µV max input offset voltage at 25°C, while the standard version allows up to 1500 µV. No PCB layout changes are required when upgrading from TLV2254IPWR to TLV2254AIPWR for improved DC precision.
What is the typical supply current per channel for the TLV2254AIPWR at 3 V operation?
The typical supply current per channel for the TLV2254AIPWR is 34 µA at VDD = 3 V and TA = 25°C, as confirmed in the "Electrical Characteristics" tables (pages 10–11 of SLOS185D). Total quiescent current for all four amplifiers is therefore ~135 µA typical. This value remains stable across the full −40°C to 125°C temperature range, with a maximum of 300 µA (75 µA per channel) specified over temperature.
