Product details
Overview
TLV2444CPW from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 10 V) single-supply operation. It delivers 1.8 MHz gain-bandwidth, 750 µA per channel supply current, 16 nV/√Hz input voltage noise at 1 kHz, 600-Ω output drive capability, and extended common-mode input range (0 V to 4.25 V min at 5 V). It is used in precision sensor signal conditioning and ADC interface circuits where rail-to-rail output swing maximizes dynamic range.
For engineers reviewing the TLV2444CPW datasheet, TLV2444CPW pinout, TLV2444CPW application, or TLV2444CPW equivalent, key selection criteria include guaranteed 950 µV max input offset voltage (TLV2444A variants), absence of phase inversion near supply rails, low 1 pA typical input bias current, and TSSOP-14 package compatibility with space-constrained analog front-ends.
Technical Context
The TLV2444CPW employs Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining wide common-mode input voltage range (0 V to VDD – 1 V) and no phase inversion when inputs approach either supply rail. Its internal architecture supports stable unity-gain operation with 600 Ω load and 100 pF capacitive load, delivering 0.75 V/µs slew rate at 5 V supply.
It is fully characterized across 3 V and 5 V supplies, with specified performance over 0°C to 70°C ambient temperature. The device exhibits high input impedance (>1000 GΩ differential and common-mode resistance), low 8 pF input capacitance, and 140 Ω closed-loop output impedance at 1 MHz - enabling direct driving of SAR ADC reference inputs and low-distortion buffering.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2444AIPW | 950 µV max input offset voltage (vs. 2.5 mV for TLV2444CPW); same TSSOP-14 package and electrical specs. | Suitable for higher-precision applications requiring <1 LSB error in 12-bit systems. | Select TLV2444AIPW when VIO stability over temperature is critical; otherwise TLV2444CPW offers cost advantage. |
| MCP6004-E/ST | Lower supply current (100 µA/ch), lower GBW (1 MHz), no guaranteed phase-inversion immunity; MSOP-14 package. | Better for ultra-low-power battery life; not recommended for high-fidelity sensor conditioning near supply rails. | Choose MCP6004-E/ST only for standby-mode signal monitoring; avoid where rail-rail input behavior or 1.8 MHz bandwidth is required. |
Compared with TLV2444AIPW, TLV2444CPW trades guaranteed low offset for broader commercial temperature range and lower cost; versus MCP6004-E/ST, it provides superior AC performance and robust rail-to-rail input behavior but consumes 7.5× more quiescent current.

FAQ
What is the maximum supply voltage rating for TLV2444CPW?
The absolute maximum supply voltage for TLV2444CPW is 12 V, but the recommended operating range is 2.7 V to 10 V. Operation above 10 V risks exceeding internal junction limits and is not characterized. At 10 V supply, the device maintains rail-to-rail output swing and 1.8 MHz gain-bandwidth, making TLV2444CPW suitable for industrial 9 V battery-powered equipment.
Does TLV2444CPW support true rail-to-rail input operation?
No, TLV2444CPW features rail-to-rail *output* but not rail-to-rail *input*. Its common-mode input voltage range extends from VDD–/GND to VDD+ – 1 V (min 4.25 V at 5 V supply). This allows inputs to reach the negative rail but not the positive rail - unlike true rail-to-rail input op-amps. However, TLV2444CPW avoids phase inversion when inputs approach either rail, a key differentiator from standard CMOS amplifiers.
Can TLV2444CPW drive a 100 pF capacitive load stably?
Yes, TLV2444CPW is characterized for stable unity-gain operation with 100 pF capacitive load and 600 Ω series resistance, achieving 68° phase margin at 5 V supply. This makes TLV2444CPW suitable for driving ADC sample-and-hold capacitors and long PCB traces without external isolation resistors. For loads >100 pF, a series resistor (≥10 Ω) is recommended to maintain stability.
What is the thermal performance of TLV2444CPW in TSSOP-14 package?
In the TSSOP-14 (PW) package, TLV2444CPW has a power dissipation rating of 525 mW at TA ≤ 25°C, derating at 4.2 mW/°C above that temperature. At full 4-channel operation (3 mA total IDD at 5 V), power dissipation is ~15 mW - well within safe limits even at 70°C ambient. No heatsink or thermal pad connection is required for standard operation.
Is TLV2444CPW qualified for automotive applications?
No, TLV2444CPW is a commercial-grade (C-suffix) part rated for 0°C to 70°C operation and is not AEC-Q100 qualified. For automotive use, TI offers the TLV2444AQPW (Q-suffix), rated for –40°C to 125°C and qualified to automotive standards. TLV2444CPW should be limited to industrial, medical, and consumer applications outside harsh automotive environments.
