Product details
Overview
TLV2241IDBVRG4 from Texas Instruments is a single-channel micropower rail-to-rail input/output operational amplifier optimized for ultra-low-power sensor signal conditioning and battery-powered instrumentation. It delivers 1 µA per channel supply current, 5.5 kHz gain bandwidth, ±200 µA output drive, and operates from 2.5 V to 12 V - enabling direct interface with Li-ion batteries and MSP430 microcontrollers in portable medical and environmental monitoring systems.
For engineers reviewing the TLV2241IDBVRG4 datasheet, TLV2241IDBVRG4 pinout, TLV2241IDBVRG4 application, or TLV2241IDBVRG4 equivalent, key selection criteria include its guaranteed rail-to-rail I/O swing at 2.7 V, 600 µV typical input offset voltage, 100 dB CMRR, 3 µV/°C offset drift, and industrial-grade –40°C to 125°C temperature range - all in a space-constrained 5-pin SOT-23 package.
Technical Context
The TLV2241IDBVRG4 employs a CMOS input stage with picoampere-level input bias current (100–500 pA), enabling high-impedance sensor interfacing without significant DC error. Its rail-to-rail output stage sustains >2.6 V swing at 2.7 V supply and >11.9 V at 12 V supply under 2 µA load, while maintaining phase margin ≥60° into 100 pF capacitive loads.
DC precision is ensured by low 600 µV typical VIO, 100 V/mV minimum open-loop gain at 2.7 V, and 100 dB CMRR across 0–10 kHz. Dynamic performance includes 2 V/ms slew rate and 1.84 ms 0.1% settling time for 1 V step at 2.7/5 V supplies - suitable for low-frequency precision amplification rather than high-speed signal processing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 1 µA/channel - enables multi-year battery life in always-on IoT sensors and wearable health monitors. |
| Input Offset Voltage | 600 µV typical - minimizes DC error in bridge sensor amplification and thermocouple conditioning circuits. |
| Gain Bandwidth Product | 5.5 kHz - supports stable closed-loop gain up to ~55 at 100 Hz, ideal for anti-aliasing and low-pass filtering. |
| Rail-to-Rail I/O | Input common-mode range: 0 V to VCC; Output swing: within 30 mV of rails at 2 µA load - maximizes dynamic range in single-supply systems. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive sensing, industrial process control, and outdoor environmental nodes. |
| Input Bias Current | 100 pA typical at 25°C - allows use with >10 MΩ source impedances without significant voltage drop or drift. |
| PSRR | 70 dB at 2.7–5 V - rejects power rail noise in mixed-signal PCBs where analog and digital sections share regulators. |
Pinout & Package
TLV2241IDBVRG4 is housed in a 5-pin SOT-23 (DBV) package with exposed pad for thermal enhancement. Pin 1 is OUT; Pin 2 is GND; Pin 3 is IN+; Pin 4 is VCC; Pin 5 is IN−. No internal connection on unused pins - consistent with family-wide DBV layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ±200 µA - drives ADC reference buffers or low-power comparators. |
| 2 (GND) | Analog ground reference | Must be connected to clean system ground plane; separation from digital ground reduces noise coupling in mixed-signal designs. |
| 3 (IN+) | Non-inverting input | CMOS input with 300 MΩ differential resistance - accepts high-Z sources like pH electrodes or piezoresistive sensors. |
| 4 (VCC) | Positive supply | Accepts 2.5–12 V; decoupling requires 0.1 µF ceramic capacitor placed ≤0.1 inch from pin to suppress supply transients. |
| 5 (IN−) | Inverting input | Matches IN+ in bias current and offset; shortest possible trace length required to minimize stray capacitance and oscillation risk. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower operation | 1 µA/channel supply current enables >10-year battery life in coin-cell-powered gas detectors and remote telemetry nodes. |
| Rail-to-rail input and output | Full 0 V to VCC input range and <30 mV rail headroom output swing maximize usable signal range in 3.3 V or lower systems. |
| Low input offset drift | 3 µV/°C ensures <1.5 mV total offset shift over –40°C to 125°C - critical for uncalibrated industrial temperature transmitters. |
| High CMRR | 100 dB at 25°C rejects common-mode noise from shared sensor cables or noisy motor-drive environments. |
| Industrial temperature grade | –40°C to 125°C operating range qualifies for engine control modules, solar inverter monitoring, and factory automation I/O cards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2241IDBV | Same die, identical electrical specs, but packaged in standard SOT-23 without G4 suffix (RoHS-compliant lead finish). | No functional difference; both rated for –40°C to 125°C and share identical pinout and thermal characteristics. | Select TLV2241IDBV if RoHS compliance without green marking is sufficient; TLV2241IDBVRG4 adds matte-tin finish for enhanced solderability and whisker resistance. |
| OPA348AIDBVR | Higher 45 µA supply current, 1 MHz GBW, 2.5 V to 5.5 V supply range - trades micropower for speed and rail-to-rail output only. | Better suited for active filters or higher-bandwidth sensor interfaces where >10 kHz response is required. | Choose OPA348AIDBVR when settling time <10 µs or bandwidth >100 kHz is needed; TLV2241IDBVRG4 remains optimal for sub-10 kHz, sub-1 µA applications. |
Compared with TLV2241IDBV, TLV2241IDBVRG4 offers identical performance with enhanced surface finish for reliability in high-reliability assembly; versus OPA348AIDBVR, it provides 45× lower supply current at the cost of bandwidth - making it superior for energy-constrained, low-frequency measurement systems.

FAQ
What is the maximum supply voltage for TLV2241IDBVRG4?
The absolute maximum supply voltage for TLV2241IDBVRG4 is 16.5 V, but the recommended operating range is 2.5 V to 12 V. Operation above 12 V risks exceeding safe power dissipation limits and may degrade long-term reliability. Electrical specifications are fully characterized at 2.7 V, 5 V, and 12 V - with 2.5 V enabling compatibility with single Li-ion cells.
Does TLV2241IDBVRG4 support true rail-to-rail input and output?
Yes, TLV2241IDBVRG4 supports true rail-to-rail input (common-mode range from 0 V to VCC) and rail-to-rail output (swing within 30 mV of both rails at 2 µA load). This is confirmed across all supply voltages (2.7 V, 5 V, 12 V) and temperature ranges, enabling full utilization of supply headroom in single-supply systems without external level-shifting circuitry.
What is the input bias current specification for TLV2241IDBVRG4?
TLV2241IDBVRG4 has a typical input bias current of 100 pA at 25°C, with a maximum of 550 pA over the full –40°C to 125°C industrial temperature range. This ultra-low bias current allows direct interfacing with high-impedance sources such as pH electrodes, photodiodes, and piezoelectric sensors without significant DC error or signal attenuation.
Can TLV2241IDBVRG4 drive capacitive loads?
TLV2241IDBVRG4 is stable with capacitive loads up to 100 pF, maintaining ≥60° phase margin per datasheet Figure 24. For loads exceeding 100 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to prevent peaking or oscillation. The device's low 2 V/ms slew rate inherently limits high-frequency instability risks in typical sensor-buffering applications.
Is TLV2241IDBVRG4 pin-compatible with other TLV224x variants?
No - TLV2241IDBVRG4 (single-channel, SOT-23-5) is not pin-compatible with TLV2242 (dual, MSOP-8) or TLV2244 (quad, TSSOP-14). Each variant has distinct pin counts, layouts, and package footprints. However, all TLV224x devices share identical electrical behavior, allowing schematic reuse with appropriate package adaptation and layout revision for the TLV2241IDBVRG4's 5-pin SOT-23 footprint.
