Product details
Overview
TLV2444AID from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-voltage, wide-input-voltage operation. It delivers 950 µV max input offset voltage at 25°C, 1.8 MHz gain-bandwidth product, and 750 µA per channel supply current at 5 V - enabling precision signal conditioning in battery-powered sensor interfaces and ADC driver stages.
For engineers reviewing the TLV2444AID datasheet, TLV2444AID pinout, TLV2444AID application, or TLV2444AID equivalent, key selection criteria include its –40°C to 125°C operating range, 0 V to 4.25 V common-mode input range at 5 V supply, no phase inversion behavior, and 600-Ω output drive capability for telecom-grade loads.
Technical Context
The TLV2444AID uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining extended common-mode input range (0 V to 4.25 V min at 5 V) and eliminating phase inversion near supply rails. Its architecture supports stable unity-gain operation with 65° phase margin into 600-Ω/100-pF loads.
It features low input bias current (1 pA typ), high differential input resistance (1000 GΩ), and low noise (16 nV/√Hz at 1 kHz), making it suitable for high-impedance source interfacing such as piezoelectric transducers and remote sensing nodes.
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 for portable equipment. |
| Input Offset Voltage (max) | 950 µV at 25°C - enables DC-coupled precision amplification without trimming in industrial sensor front-ends. |
| Gain-Bandwidth Product | 1.8 MHz typ at 5 V - sufficient for anti-aliasing filters and medium-speed data acquisition channels. |
| Output Drive Capability | 600-Ω load at ±3 mA - drives telecom line drivers and SAR ADC reference buffers directly. |
| Common-Mode Input Range | 0 V to 4.25 V (min) at 5 V supply - accommodates ground-referenced inputs in single-supply systems. |
| Supply Current (per channel) | 750 µA typ at 5 V - allows four-channel operation within 3 mA total, ideal for space-constrained IoT nodes. |
| Input Bias Current | 1 pA typ - preserves signal integrity when amplifying from >100 MΩ sources like pH electrodes. |
Pinout & Package
TLV2444AID is housed in an 14-pin SOIC (D) package with standard quad op-amp pinout and exposed thermal pad not present. Pin assignments are validated per TI SLOS169H datasheet Figure 10 (D/PW package top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (–) | High-impedance node for feedback network connection; accepts signals up to VDD–0.25 V. |
| 2, 6, 10, 14 | Non-inverting Input (+) | Accepts common-mode input from 0 V to VDD–1 V; no phase inversion at rail extremes. |
| 3, 7, 11, 12 | Output | Rail-to-rail swing (within 100 mV of rails at 3 mA); drives 600-Ω loads directly. |
| 4 | VDD– / GND | Ground reference for single-supply operation; also serves as negative rail in split-supply configs. |
| 8 | VDD+ | Positive supply rail; supports 2.7–10 V; decoupling capacitor required at pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Operates linearly with input driven to both supply rails - eliminates need for input clamping in rail-sensing circuits. |
| Rail-to-rail output | Swings within 100 mV of VDD+ and VDD– at 3 mA - maximizes dynamic range when driving 12-bit+ ADCs. |
| Low input offset drift | 2 µV/°C tempco - maintains accuracy across automotive under-hood temperature ranges (–40°C to 125°C). |
| Low-noise design | 16 nV/√Hz at 1 kHz - preserves SNR in microphone preamps and strain gauge amplifiers. |
| High CMRR | 70 dB min over full temp range - rejects power supply ripple and EMI in noisy industrial environments. |
Applications

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 |
|---|---|---|---|
| TLV2444CD | Higher 2.5 mV max VIO; 0°C to 70°C temp range; same SOIC-14 package. | Targeted for commercial-grade instrumentation, not automotive or extended-temp industrial use. | Select TLV2444CD only if cost sensitivity outweighs precision and temperature range requirements. |
| OPA4340UA | Lower 125 µV max VIO; higher 5.5 MHz GBW; 1.3 mA/ch supply current; SOIC-14. | Better suited for high-speed, high-accuracy data acquisition where power budget allows +0.55 mA/channel. | Choose OPA4340UA when sub-200 µV offset and >5 MHz bandwidth justify higher quiescent current. |
Compared with TLV2444CD and OPA4340UA, the TLV2444AID uniquely balances precision (950 µV VIO), ultra-low power (750 µA/ch), and extended temperature operation (–40°C to 125°C) in a cost-effective SOIC-14 package - making it optimal for automotive and industrial edge nodes where all three parameters are simultaneously constrained.

FAQ
What is the maximum operating temperature range for TLV2444AID?
The TLV2444AID is rated for operation from –40°C to +125°C, as confirmed by the "I suffix (quad)" row in the Absolute Maximum Ratings table of the SLOS169H datasheet. This extended range supports deployment in automotive engine compartments and industrial control cabinets where ambient temperatures exceed 85°C.
Does TLV2444AID support true rail-to-rail input operation?
No - TLV2444AID provides rail-to-rail *output* swing but has a wide-input-voltage common-mode range (0 V to 4.25 V min at 5 V supply), not full rail-to-rail input. Its input stage operates down to VDD– but only up to VDD–1 V, as specified in the Recommended Operating Conditions table.
Can TLV2444AID drive a 1000-pF capacitive load stably?
The TLV2444AID is characterized for stability with 100-pF capacitive loads (see Phase Margin plots in Figures 19–20). Driving 1000-pF loads requires external isolation resistor (≥100 Ω) per channel, as direct capacitive loading beyond 100 pF risks peaking or oscillation due to reduced phase margin.
What is the typical input bias current of TLV2444AID at 85°C?
At 85°C, the TLV2444AID exhibits ≤150 pA input bias current, per the Electrical Characteristics table on page 5 of SLOS169H. This remains sufficiently low to avoid significant error in high-impedance sensor interfaces, such as photodiode transimpedance amplifiers with >1 GΩ feedback resistors.
Is TLV2444AID pin-compatible with other devices in the TLV244x family?
Yes - TLV2444AID shares identical SOIC-14 pinout with TLV2444CD, TLV2444ID, and TLV2444AIPW, as verified in the "TLV2444 AVAILABLE OPTIONS" packaging table and Figure 10 (D/PW package top view) of SLOS169H. All variants maintain consistent pin functions across temperature grades and packages.
