Product details
Overview
TLV2444ID 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, 16 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing (0 V to 4.25 V min at 5-V supply) with no phase inversion-enabling precision signal conditioning in battery-powered sensor interfaces and ADC driver stages.
For engineers reviewing the TLV2444ID datasheet, TLV2444ID pinout, TLV2444ID application, or TLV2444ID equivalent, key selection criteria include its –40°C to 125°C operating range, 950 µV max input offset voltage (TLV2444A-grade), 600-Ω output drive capability, extended common-mode input range (0 V to 4.25 V), and compatibility with single-supply 2.7–10 V systems.
Technical Context
The TLV2444ID uses Advanced LinCMOS™ process technology to achieve high input impedance (>1 TΩ), ultra-low input bias current (1 pA typ), and rail-to-rail output stage without phase inversion-critical for driving ADCs across full supply rails. Its architecture supports stable unity-gain operation with 68° phase margin at 5 V with 600 Ω load and 100 pF capacitance.
It is fully characterized at 3-V and 5-V supplies, with guaranteed performance over –40°C to 125°C. The device exhibits low THD+N (0.17% at 1 kHz, AV = 10, RL = 600 Ω) and 0.75 V/µs slew rate, making it suitable for medium-speed precision amplification where power, noise, and dynamic range must be balanced.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-supply operation in portable and industrial systems with wide input rail tolerance. |
| Gain-Bandwidth Product | 1.8 MHz typ at 5 V - enables stable closed-loop gain up to ~10× at 100 kHz for anti-aliasing or sensor amplification. |
| Input Offset Voltage | 950 µV max at TA = 25°C (TLV2444A variant) - ensures ≤1 LSB error when driving 12-bit ADCs with 5-V reference. |
| Output Drive Capability | 600-Ω load drive - sustains rail-to-rail swing into telecom and data-acquisition loads without external buffering. |
| Input Voltage Noise | 16 nV/√Hz typ at f = 1 kHz - preserves SNR in low-level transducer signal chains (e.g., piezoelectric sensors). |
| Common-Mode Input Range | 0 V to 4.25 V min at 5-V supply - accepts inputs down to ground, simplifying level-shifting in single-supply front ends. |
| Supply Current per Channel | 750 µA typ at 5 V - enables four-channel precision amplification within 3 mA total, ideal for space-constrained IoT nodes. |
Pinout & Package
TLV2444ID is packaged in a 14-pin SOIC (D package) with exposed pad not present; pinout is fully compatible with industry-standard quad op-amp layouts and PCB footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2, 6, 10, 14 | Non-inverting Input (+) | Accepts common-mode voltages from VDD– to VDD+ – 1.3 V; no phase inversion at rails. |
| 3, 7, 11, 12 | Output | Rail-to-rail output capable of sourcing/sinking ±5 mA; drives 600-Ω loads to within 0.8 V of rails at 5 V. |
| 4 | VDD– / GND | Ground reference for single-supply operation or negative rail in split-supply configurations. |
| 14 | VDD+ | Positive supply terminal; supports 2.7–10 V operation with 80 dB supply rejection ratio. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Common-mode input extends to both supply rails without output polarity reversal-eliminates need for input clamping in rail-sensing circuits. |
| Rail-to-rail output | Swings within 0.02 V of VDD– and 0.03 V of VDD+ at light load-maximizes dynamic range when interfacing with 5-V or 3.3-V ADCs. |
| Low input bias current | 1 pA typical-minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiode transimpedance stages). |
| Extended temperature range | Specified from –40°C to +125°C-qualified for under-hood automotive and industrial control applications. |
| Macromodel included | SPICE model provided by TI-enables accurate AC, transient, and stability simulation before prototyping. |

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 | 0°C to 70°C temp range; 2.5 mV max VIO vs. 950 µV for TLV2444ID - higher offset, narrower temperature coverage. | Commercial-grade only; unsuitable for automotive or extended industrial environments. | Select TLV2444CD only for cost-sensitive consumer applications with ambient temperature control. |
| OPA2340UA | Single-supply rail-to-rail I/O; 0.55 V/µs slew rate; 20 nV/√Hz noise; 1.25 mA/ch supply current - slower, noisier, higher power than TLV2444ID. | Optimized for ultra-low distortion audio; lacks guaranteed 125°C operation and 600-Ω drive spec. | Choose OPA2340UA only when dual rail-to-rail input/output is mandatory and speed/noise trade-offs are acceptable. |
Compared with TLV2444CD and OPA2340UA, TLV2444ID provides superior temperature robustness, lower input offset, lower noise, and higher output drive-making it the preferred choice for precision, high-reliability quad-amplifier roles in harsh environments.

FAQ
What is the operating temperature range of the TLV2444ID?
The TLV2444ID is rated for operation from –40°C to +125°C, meeting extended industrial and automotive under-hood requirements. This range is explicitly defined in the "recommended operating conditions" table of the SLOS169H datasheet and validated across all electrical parameters including input offset voltage, CMRR, and output drive capability.
Does TLV2444ID support true rail-to-rail output swing?
Yes, TLV2444ID provides rail-to-rail output swing: at 5-V supply, it achieves VOH ≥ 4.0 V and VOL ≤ 0.8 V with 5-mA load, and swings to within 0.02 V of VDD– and 0.03 V of VDD+ under light load. This behavior is confirmed in Figures 10 and 12 of the TLV2444ID datasheet and enables direct interfacing with 5-V or 3.3-V ADCs without level-shifting circuitry.
Is TLV2444ID pin-compatible with other quad op-amps in SOIC-14 packages?
TLV2444ID follows the standard SOIC-14 quad op-amp pinout (pin 1 = OUT A, pin 2 = IN– A, pin 3 = IN+ A, pin 4 = V–, pin 5 = IN+ B, etc.), matching industry conventions used by LM324, TL074, and OPA4340. However, functional compatibility requires verification of supply range, input common-mode range, and output drive-TLV2444ID's rail-to-rail output and extended VICR distinguish it from legacy parts.
What is the maximum capacitive load TLV2444ID can drive stably?
TLV2444ID maintains stability with up to 100 pF capacitive load when driving a 600-Ω resistor, as verified by 68° phase margin at unity gain (SLOS169H, page 8). Driving larger capacitive loads requires isolation resistance or careful compensation; the datasheet does not guarantee stability beyond 100 pF without external network design.
How does TLV2444ID differ from TLV2444AID?
TLV2444ID and TLV2444AID share identical package, pinout, and temperature range (–40°C to +125°C), but TLV2444AID guarantees ≤950 µV input offset voltage at 25°C, whereas TLV2444ID specifies ≤2.5 mV. Both meet the same 1500 µV max VIO over full temperature range. TLV2444AID is selected for higher-precision applications such as 12-bit+ data acquisition where initial offset matters most.
