Product details
Overview
TLV2241IDBVT from Texas Instruments is a single-channel micropower rail-to-rail input/output operational amplifier in a 5-pin SOT-23 package, delivering 1 µA/channel supply current, 5.5 kHz gain bandwidth product, and operation from 2.5 V to 12 V. It features 600 µV typical input offset voltage, 100 dB CMRR, and rail-to-rail output swing-ideal for low-power sensor signal conditioning in battery-powered instrumentation.
For engineers reviewing the TLV2241IDBVT datasheet, TLV2241IDBVT pinout, TLV2241IDBVT application, or TLV2241IDBVT equivalent, this page provides verified electrical specifications, industrial-grade (–40°C to 125°C) temperature performance, SOT-23 thermal characteristics, and real-world op-amp selection guidance for ultra-low-power analog front-ends.
Technical Context
The TLV2241IDBVT employs a CMOS input stage enabling femtoampere-level input bias currents (<500 pA), supporting high-impedance sensor interfaces with megaohm-level feedback networks. Its rail-to-rail input common-mode range (0 V to VCC) and output swing (within 180 mV of rails at IOL/IOH = 50 µA) ensure full dynamic range utilization across its 2.5–12 V supply window.
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). The device maintains DC precision with 3 µV/°C offset drift and 100 V/mV minimum open-loop gain at 2.7 V, enabling accurate DC-coupled amplification in portable medical and environmental monitoring systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 1 µA per channel - enables multi-year battery life in always-on IoT sensor nodes using coin cells or Li-ion batteries. |
| Gain Bandwidth Product | 5.5 kHz - suitable for DC to low-frequency signal conditioning (e.g., thermistor, RTD, pH electrode outputs). |
| Input Offset Voltage | 600 µV typical (3000 µV max at 25°C) - supports <1% error in 100 mV full-scale sensor measurements without trimming. |
| Rail-to-Rail I/O | Input range: 0 V to VCC; Output swing: within 180 mV of rails at 50 µA load - maximizes ADC input range in single-supply data acquisition. |

| Supply Voltage Range | 2.5 V to 12 V - compatible with 2-cell alkaline, Li-ion (2.7–4.2 V), and 5 V/12 V system rails without level-shifting. |
| CMRR | 100 dB typical at 25°C - rejects common-mode noise in noisy industrial environments (e.g., motor drive feedback loops). |
Pinout & Package
TLV2241IDBVT is housed in a 5-pin SOT-23 (DBV) package with exposed pad not electrically connected. Thermal resistance θJA = 324.1°C/W enables operation at ambient temperatures up to 125°C with appropriate PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN–) | Inverting input | High-impedance CMOS node; accepts signals from 0 V to VCC; requires matched trace impedance for noise rejection. |
| 2 (IN+) | Non-inverting input | High-impedance CMOS node; used for reference voltage buffering or sensor excitation feedback paths. |
| 3 (VCC) | Positive supply | Accepts 2.5–12 V; requires local 0.1 µF ceramic decoupling placed ≤0.1 inch from pin per TI layout guidelines. |
| 4 (GND) | Ground reference | Low-inductance connection to solid ground plane; critical for maintaining PSRR >60 dB and minimizing offset drift. |
| 5 (OUT) | Amplifier output | Rail-to-rail capable; drives loads ≥500 kΩ directly; limited to ±200 µA short-circuit current per absolute max ratings. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail input/output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2401CDCKR | Lower VIO (390 µV typ), higher supply current (0.88 µA), same SOT-23-5 package. | Better DC accuracy but 88% higher current draw - trade-off favors TLV2241IDBVT for multi-year battery life. | Select TLV2241IDBVT when microampere-level current is mandatory; choose TLV2401CDCKR only if offset-limited precision dominates power budget. |
| OPA333AIDBVR | Zero-drift architecture, 10 µV VIO max, 17 µA supply current, same SOT-23-5 footprint. | Superior long-term stability and drift performance, but 17× higher current - unsuitable for energy-harvesting or coin-cell designs. | Choose OPA333AIDBVR only for applications requiring <1 µV/°C drift over 10 years; TLV2241IDBVT remains optimal for ultra-low-power constraints. |
Compared with TLV2401CDCKR and OPA333AIDBVR, the TLV2241IDBVT uniquely balances sub-1-µA operation, rail-to-rail I/O, and industrial temperature range - making it the only viable option for battery-powered sensor nodes requiring >5-year operation without maintenance.

FAQ
What is the maximum supply voltage for TLV2241IDBVT?
The absolute maximum supply voltage for TLV2241IDBVT is 16.5 V, but the recommended operating range is 2.5 V to 12 V. Operating above 12 V risks exceeding safe power dissipation limits and may degrade long-term reliability. Electrical specifications are guaranteed at 2.7 V, 5 V, and 12 V per the SLOS329C datasheet.
Does TLV2241IDBVT support rail-to-rail output at full rated load?
TLV2241IDBVT delivers rail-to-rail output swing within 180 mV of each rail at 50 µA load current and 2.7 V supply, per datasheet Figure 12. At lighter loads (<2 µA), output reaches within 30 mV of rails. Full rail-to-rail capability assumes proper PCB layout with localized 0.1 µF decoupling and minimized trace inductance on VCC and GND pins.
Can TLV2241IDBVT be used with a 1.8-V supply?
No - TLV2241IDBVT has a minimum recommended supply voltage of 2.5 V. Operation below 2.5 V is not characterized and may result in undefined behavior, including loss of rail-to-rail output swing, reduced open-loop gain, or failure to meet specified offset voltage or CMRR. For 1.8-V systems, consider TI's TLV8801 or similar 1.8-V–optimized op-amps.
What is the thermal performance of TLV2241IDBVT in SOT-23 package?
TLV2241IDBVT in DBV (SOT-23-5) package has θJA = 324.1°C/W and θJC = 55°C/W. At 125°C ambient and 1 µA supply current, junction temperature rise is ~0.3°C - well within the 150°C absolute maximum. Adequate copper pour under the exposed pad (if present) further improves thermal performance, though the DBV package lacks an exposed thermal pad per TI's DBV mechanical drawing.
Is TLV2241IDBVT pin-compatible with other SOT-23 op-amps like MCP6001?
No - TLV2241IDBVT uses a non-standard SOT-23 pinout: Pin 1 = IN–, Pin 2 = IN+, Pin 3 = VCC, Pin 4 = GND, Pin 5 = OUT. Most competing SOT-23 op-amps (e.g., MCP6001, LMV321) use Pin 1 = OUT, Pin 2 = IN–, Pin 3 = IN+, Pin 4 = GND, Pin 5 = VCC. PCB layout must be designed specifically for TLV2241IDBVT's pin assignment.
