Product details
Overview
TLV2444IDR from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-voltage, single-supply operation (2.7 V to 10 V). It delivers 1.8 MHz gain-bandwidth, 750 µA per channel supply current, 16 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing - enabling high dynamic range signal conditioning in battery-powered sensor interfaces and ADC drivers.
For engineers reviewing the TLV2444IDR datasheet, TLV2444IDR pinout, TLV2444IDR application, or TLV2444IDR equivalent, key selection criteria include its –40°C to 125°C operating temperature range, 950 µV max input offset voltage (TLV2444A-grade), 600-Ω output drive capability, and absence of phase inversion at rail inputs - critical for precision analog front-ends in industrial monitoring and automotive subsystems.
Technical Context
The TLV2444IDR 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 supply) and no phase inversion near supply rails. Its architecture supports stable unity-gain operation with 600 Ω load and 100 pF capacitive load, delivering 68° phase margin at 5 V.
It features low input bias current (1 pA typ), high input impedance (>1 TΩ), and low power dissipation - making it suitable for interfacing with high-impedance sources like piezoelectric transducers and electrochemical sensors without loading or DC error degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - enables direct operation from single Li-ion or dual alkaline cells without regulation. |
| Gain-Bandwidth Product | 1.8 MHz typ at 5 V - supports stable closed-loop gain up to ~10× at audio and low-speed control bandwidths. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C (TLV2444A grade) - ensures ≤1 LSB error when driving 12-bit ADCs with 2.5 V reference. |
| Output Drive Capability | ±5 mA into 600 Ω load - sufficient to drive telecom line interfaces and buffered DAC outputs without external amplification. |
| Input Voltage Noise | 16 nV/√Hz at f = 1 kHz - preserves SNR in low-level sensor signal chains (e.g., thermopile, strain gauge). |
| Common-Mode Input Range | 0 V to 4.25 V (min) at 5 V supply - allows direct sensing of ground-referenced signals without level-shifting circuitry. |
| Slew Rate | 0.75 V/µs typ at 5 V - adequate for <100 kHz full-power signal reproduction with <1% distortion. |
Pinout & Package
TLV2444IDR is housed in a 14-pin SOIC (D) package with standard quad op-amp pinout and tape-and-reel packaging (R suffix). The device shares pin compatibility across the TLV244x family.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8, 12 | Output (OUT1–OUT4) | Rail-to-rail capable outputs; each drives ±5 mA into 600 Ω with <1.25 V drop from rails at 5 V supply. |
| 2, 6, 9, 13 | Inverting Input (IN–) | High-impedance node (1000 GΩ); accepts common-mode voltages from VDD– to VDD+ – 1.3 V. |
| 3, 7, 10, 14 | Non-inverting Input (IN+) | Same common-mode range as IN–; no phase inversion when driven to either rail. |
| 4 | VDD– / GND | Ground reference for single-supply operation; also serves as negative rail in split-supply configurations. |
| 11 | VDD+ | Positive supply input; supports 2.7 V to 10 V; decoupling capacitor required for stability. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion at rail inputs | Enables direct connection of ground-referenced sensors without clamping diodes or input protection networks. |
| Rail-to-rail output swing | Delivers >99% of full-scale output voltage range, maximizing dynamic range when interfacing with 12-bit+ ADCs. |
| Low 1-pA input bias current | Minimizes voltage error across high-value feedback resistors (e.g., >1 MΩ), preserving gain accuracy in transimpedance stages. |
| Extended common-mode input range | Accepts inputs down to VDD– and up to VDD+ – 1.3 V, eliminating need for input biasing in single-supply applications. |
| Optimized for 3-V and 5-V supplies | Characterized across full temperature range at both voltages - simplifies design reuse across portable and industrial platforms. |

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 |
|---|---|---|---|
| TLV2444CDR | 0°C to 70°C temp range; 2.5 mV max VIO vs. 950 µV for TLV2444IDR | Commercial-grade only; unsuitable for automotive or extended-temperature industrial use | Select TLV2444CDR only for cost-sensitive consumer electronics with benign ambient conditions. |
| OPA2340UA/2K5 | Higher 5.5 MHz GBW but 1.8 mA/ch supply current; 10 µV max VIO | Better precision and speed, but 2.4× higher quiescent power and narrower supply range (2.7 V to 5.5 V) | Choose OPA2340UA when ultra-low offset and faster settling are required, accepting higher power and reduced voltage flexibility. |
Compared with TLV2444CDR, TLV2444IDR provides guaranteed performance over –40°C to 125°C and tighter input offset, making it suitable for harsh environments; versus OPA2340UA, TLV2444IDR offers lower power and wider supply range at the expense of precision and bandwidth - favoring battery life and design flexibility in embedded systems.

FAQ
What is the operating temperature range for TLV2444IDR?
The TLV2444IDR is rated for operation from –40°C to 125°C, meeting industrial and automotive-grade requirements. This range is confirmed in the "Recommended Operating Conditions" table of the SLOS169H datasheet, where the "I suffix (quad)" explicitly specifies –40°C to 125°C. The D-package construction and internal qualification support reliable performance across this full range without derating.
Does TLV2444IDR support true rail-to-rail input operation?
No, TLV2444IDR features rail-to-rail *output* but not rail-to-rail *input*. Its common-mode input voltage range extends from VDD– to VDD+ – 1.3 V at 5 V supply (0 V to 4.25 V min), as specified in the datasheet's recommended operating conditions. While it avoids phase inversion when inputs approach the rails, it does not accept signals beyond those limits - distinguishing it from full rail-to-rail input/output amplifiers.
What is the maximum capacitive load TLV2444IDR can drive stably?
TLV2444IDR maintains stability with up to 100 pF capacitive load when driving a 600 Ω load, as verified by phase margin measurements (68° at 5 V, RL = 600 Ω, CL = 100 pF) in the datasheet's operating characteristics tables. Driving larger capacitive loads requires isolation resistance or careful compensation per application-specific layout and load conditions.
Is TLV2444IDR pin-compatible with other quad op-amps in SOIC-14 packages?
TLV2444IDR follows the industry-standard quad op-amp pinout (pin 1 = OUT1, pin 2 = IN1–, pin 3 = IN1+, pin 4 = V–, etc.) and is pin-compatible with TLV2444CDR, TLV2444IPW, and legacy TI devices like TLC27L4. However, electrical differences (e.g., VIO, temp range, drive strength) require validation in the target circuit before substitution.
How does the input offset voltage specification differ between TLV2444IDR and TLV2444CDR?
TLV2444IDR (I-suffix, A-grade) guarantees ≤950 µV max input offset voltage at TA = 25°C, while TLV2444CDR (C-suffix) specifies ≤2.5 mV max. This 2.6× tighter VIO tolerance makes TLV2444IDR suitable for precision applications such as 12-bit ADC buffering where offset-induced errors must remain below 1 LSB with a 2.5 V reference.
