Product details
Overview
TLV2244IPW from Texas Instruments is a quad micropower rail-to-rail input/output operational amplifier in 14-pin TSSOP package, delivering 1 µA per channel supply current, 5.5 kHz gain bandwidth product, and operation from 2.5 V to 12 V - enabling ultra-low-power sensor signal conditioning in battery-powered portable instrumentation.
For engineers reviewing the TLV2244IPW datasheet, TLV2244IPW pinout, TLV2244IPW application, or TLV2244IPW equivalent, this page provides verified electrical parameters, validated pin functions, real-world use cases in Li-ion–powered systems, and two confirmed alternative op-amps with documented functional trade-offs.
Technical Context
The TLV2244IPW implements a CMOS input stage with rail-to-rail common-mode input range (0 V to VCC) and rail-to-rail output swing (within 180 mV of rails at 50 µA load), supporting single-supply operation down to 2.5 V - compatible with MSP430 microcontrollers and Li-ion battery systems. Its 600 µV typical input offset voltage and 100 dB CMRR ensure DC precision in high-impedance sensor interfaces.
Designed for stability with capacitive loads up to 100 pF, it achieves 60° phase margin and 15 dB gain margin under standard test conditions (RL = 500 kΩ, CL = 100 pF), while its 2 V/ms slew rate and 1.84 ms 0.1% settling time suit low-frequency precision amplification - not high-speed signal processing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail input/output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2404IPW | Lower 0.88 µA/channel supply current; 5 kHz GBW; 0.39 mV VIO max; reverse-battery protected | Better suited for ultra-long-life battery systems where 0.12 µA/channel savings matters over decades | Select TLV2404IPW when reverse-battery protection is required or when offset voltage < 390 µV is mandatory |
| OPA2333PWR | Zero-drift architecture; 0.02 µV/°C drift; 350 nA/channel; 350 kHz GBW; higher cost | Required for DC-coupled thermocouple amplifiers or strain-gauge bridges needing <1 µV drift over temperature | Choose OPA2333PWR only when microvolt-level drift stability outweighs 35× higher supply current and cost |
Compared with TLV2244IPW, TLV2404IPW offers lower supply current and reverse-battery protection but slightly reduced CMRR (94 dB vs. 100 dB); OPA2333PWR delivers near-zero drift and higher bandwidth but consumes 350× more current - making TLV2244IPW optimal for cost-sensitive, long-life, moderate-precision analog sensing.

FAQ
What is the maximum operating junction temperature for TLV2244IPW?
The absolute maximum junction temperature for TLV2244IPW is 150°C. This limit is defined in the Absolute Maximum Ratings table and applies across the full industrial temperature range (–40°C to +125°C ambient). Derating is required above 125°C ambient per the dissipation rating table - for example, at 125°C ambient, maximum allowable power dissipation in the PW package is 144 mW based on θJA = 173.6°C/W. Exceeding 150°C risks permanent parametric shift or failure.
Does TLV2244IPW support true rail-to-rail output swing at full rated load?
TLV2244IPW achieves rail-to-rail output swing within 180 mV of each rail at 50 µA load and within 260 mV at 50 µA load over full temperature range - verified in the Electrical Characteristics table. At lighter loads (e.g., 2 µA), output swing improves to within 90 mV of rails. It does not reach true 0-V or VCC output under heavy load, but the guaranteed headroom enables >95% of full-scale dynamic range utilization in 12-bit systems powered from 3.3 V or 5 V supplies.
Can TLV2244IPW operate from a single 2.5-V supply with guaranteed specifications?
Yes - TLV2244IPW is fully specified and tested at 2.7 V, 5 V, and 12 V, with recommended operating conditions explicitly listing 2.5 V as the minimum supply voltage. All key parameters including input offset voltage, CMRR, PSRR, and output swing are characterized down to 2.5 V. The 2.5-V minimum enables direct compatibility with deeply discharged Li-ion cells (2.8 V nominal) and low-voltage microcontrollers such as the MSP430FR2355.
What is the input common-mode voltage range for TLV2244IPW?
The input common-mode voltage range for TLV2244IPW is 0 V to VCC, confirmed in the Recommended Operating Conditions table and validated across all supply voltages (2.5 V to 12 V) and temperature ranges. This rail-to-rail input capability allows direct interfacing with sensors whose output spans the full supply range - such as resistive divider-based temperature sensors or bridge transducers - without external level-shifting circuitry.
Is TLV2244IPW pin-compatible with other devices in the TLV224x family?
No - TLV2244IPW (14-pin TSSOP) is not pin-compatible with TLV2241 (5-pin SOT-23) or TLV2242 (8-pin MSOP). However, within the quad variant group, TLV2244IPW shares identical pinout with TLV2244CD (14-pin SOIC) and TLV2244IN (14-pin PDIP), as shown in the Family Package Table and Pinouts section. This allows drop-in replacement between PW, D, and N packages when board layout permits footprint adaptation.
