Product details
Overview
TLV2444AIPW from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-voltage, wide-input-voltage operation. It delivers 1.8 MHz gain-bandwidth, 750 µA per-channel supply current, 950 µV max input offset voltage at 25°C, and rail-to-rail output swing (0 V to VDD) with no phase inversion-enabling precision signal conditioning in single-supply sensor interfaces and ADC drivers.
For engineers reviewing the TLV2444AIPW datasheet, TLV2444AIPW pinout, TLV2444AIPW application, or TLV2444AIPW equivalent, this device is selected for low-noise (16 nV/√Hz), high-impedance (1 TΩ input resistance), and 600-Ω load drive capability in battery-powered instrumentation and industrial analog front-ends where common-mode range extends to 0 V and 4.25 V at 5-V supply.
Technical Context
The TLV2444AIPW uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing without phase inversion across the full common-mode input range (0 V to VDD − 1 V). Its input stage operates with extended common-mode range and ultra-low input bias current (1 pA typ), making it suitable for high-impedance source interfacing such as piezoelectric transducers and pH sensors.
It features internal compensation for unity-gain stability into 600-Ω loads and exhibits 0.75 V/µs slew rate at 5-V supply. The device is fully characterized from −40°C to +125°C and specified for 2.7-V to 10-V operation, supporting both single- and split-supply configurations while maintaining low THD+N (0.17% at 1 kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-supply operation down to 2.7 V and compatibility with 3.3 V and 5 V systems. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - enables precision DC-coupled amplification without external trimming in 12-bit ADC interfaces. |
| Gain-Bandwidth Product | 1.8 MHz typ at VDD = 5 V - sufficient for anti-aliasing filters and sensor signal conditioning up to ~100 kHz. |
| Output Drive Capability | 600-Ω load drive - directly interfaces with telecom line drivers and buffered DAC outputs without external buffers. |
| Input Bias Current | 1 pA typ - preserves signal integrity when amplifying from high-impedance sources (>100 MΩ) like photodiodes or electrochemical sensors. |
| Common-Mode Input Range | 0 V to 4.25 V (min) at 5-V supply - allows direct sensing of signals referenced to ground in single-supply systems. |
| Supply Current per Channel | 750 µA typ at VDD = 5 V - enables four-channel operation in portable equipment with sub-3-mA total quiescent draw. |
Pinout & Package
TSSOP-14 package (PW), 4.4 mm × 5.0 mm, 0.65 mm pitch, thermally enhanced for stable operation at 125°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (−) | High-impedance differential input node for each of four op-amp channels; accepts common-mode voltages from VDD– to VDD+ − 1 V. |
| 2, 6, 10, 14 | Non-inverting Input (+) | High-impedance differential input node; supports rail-to-rail common-mode range and zero-phase-inversion behavior. |
| 3, 7, 11, 12 | Output | Rail-to-rail output capable of swinging within 100 mV of supply rails under 3 mA load; drives 600-Ω loads directly. |
| 4 | VDD− / GND | Ground reference for dual-supply operation or system ground in single-supply configurations. |
| 8 | VDD+ | Positive supply rail; accepts 2.7 V to 10 V; decoupling capacitor required adjacent to pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Common-mode input driven to supply rails causes no output polarity reversal - eliminates design risk in overvoltage-tolerant sensor front-ends. |
| Rail-to-rail output | Swings within 100 mV of VDD+ and VDD− at 3 mA load - maximizes dynamic range when driving 12-bit ADCs with 0–5 V input ranges. |
| Low input offset voltage (950 µV max) | Guaranteed over temperature (−40°C to +125°C) - reduces calibration overhead in automotive and industrial temperature-sensing modules. |
| Ultra-low input bias current (1 pA typ) | Enables >100 GΩ effective source impedance handling - critical for accurate amplification of piezoelectric and ion-selective electrode signals. |
| Low noise (16 nV/√Hz at 1 kHz) | Lower than competing CMOS op-amps - improves SNR in low-level signal chains such as medical ECG preamplifiers and strain gauge bridges. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2444CPW | 2.5 mV max input offset voltage (vs. 950 µV for TLV2444AIPW); same pinout, package, and electrical specs otherwise. | Suitable for cost-sensitive industrial controls where ±2.5 mV offset is acceptable; not recommended for precision 12-bit+ data acquisition. | Select TLV2444CPW only if offset drift and long-term stability requirements are relaxed; verify system-level accuracy budget. |
| OPA4340UA | Higher precision (125 µV max VIO), lower noise (8 nV/√Hz), but higher supply current (750 µA vs. 750 µA - same typ, but OPA4340 has tighter max spec), and no AEC-Q100 qualification. | Better suited for lab-grade instrumentation; lacks automotive temperature range and qualified reliability data for harsh environments. | Choose OPA4340UA when absolute DC accuracy outweighs automotive qualification and thermal robustness requirements. |
Compared with TLV2444CPW and OPA4340UA, the TLV2444AIPW uniquely balances AEC-Q100-compliant operation, guaranteed 950 µV offset, and 1 pA input bias - making it optimal for automotive and industrial designs requiring both precision and ruggedness without premium cost.

FAQ
What is the maximum operating temperature range for TLV2444AIPW?
The TLV2444AIPW is rated for operation from −40°C to +125°C, meeting AEC-Q100 Grade 1 requirements for automotive applications. This extended range is confirmed in the "Recommended Operating Conditions" table of the SLOS169H datasheet, where the I-suffix (quad version) explicitly specifies −40°C to +125°C.
Does TLV2444AIPW support true rail-to-rail input?
No, TLV2444AIPW provides rail-to-rail *output* swing only. Its common-mode input voltage range is 0 V to VDD − 1 V (min 4.25 V at 5-V supply), as specified in the "Recommended Operating Conditions" section. It does not accept inputs at the positive rail - unlike rail-to-rail input op-amps.
Can TLV2444AIPW drive a 1000-pF capacitive load stably?
The TLV2444AIPW is internally compensated for unity-gain stability with resistive loads up to 600 Ω. Driving >100 pF capacitive loads requires external isolation resistance (e.g., 10–50 Ω in series with the output) per Figure 48 (phase margin vs. load capacitance) in the datasheet - direct 1000-pF loading risks oscillation.
Is TLV2444AIPW pin-compatible with TLV2444CPW?
Yes, TLV2444AIPW and TLV2444CPW share identical TSSOP-14 (PW) packaging, pinout, and footprint. Both are quad op-amps with identical terminal assignments (pins 1–14), enabling drop-in replacement where offset voltage tolerance permits.
What is the typical input noise voltage of TLV2444AIPW at 1 kHz?
The typical equivalent input noise voltage of TLV2444AIPW is 16 nV/√Hz at 1 kHz and VDD = 5 V, as measured and published in the "Operating Characteristics" table on page 8 of the SLOS169H datasheet - matching the 16 nV/√Hz value cited in the device overview.
