Product details
Overview
TLV2241CDG4 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, 600 µV typical input offset voltage, and operates from 2.5 V to 12 V - enabling direct interface with Li-ion batteries and MSP430 microcontrollers.
For engineers reviewing the TLV2241CDG4 datasheet, TLV2241CDG4 pinout, TLV2241CDG4 application, or TLV2241CDG4 equivalent, this page provides verified electrical specifications, SOT-23-5 package details, rail-to-rail I/O behavior at 2.7 V/5 V/12 V, thermal performance data, and validated alternative op-amps for low-power analog front-end design.
Technical Context
The TLV2241CDG4 employs CMOS input stage architecture enabling femtoampere-level input bias currents (100–550 pA), supporting high-impedance sensor interfaces up to megaohm range. Its rail-to-rail input common-mode range (0 V to VCC) and output swing within 180 mV of rails at 50 µA load ensure full dynamic range utilization in single-supply systems.
Designed for stability with capacitive loads up to 100 pF, it achieves 60° phase margin and 15 dB gain margin while maintaining 2 V/ms slew rate and 1.84 ms 0.1% settling time (VSTEP = 1 V, RL = 100 kΩ). Electrical characteristics are fully specified across 2.7 V, 5 V, and 12 V supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 1 µA/channel - enables multi-year operation on coin-cell batteries in always-on sensing nodes. |
| Input Offset Voltage | 600 µV typical at 25°C - ensures <1 LSB error in 12-bit ADC interfaces with gain ≤10. |
| Gain Bandwidth Product | 5.5 kHz - supports DC-coupled amplification of slow-varying biosignals (ECG, temperature) without instability. |
| Rail-to-Rail I/O | Input: 0 V to VCC; Output: within 180 mV of rails at 50 µA - maximizes signal swing in 3.3 V or lower systems. |
| Supply Voltage Range | 2.5 V to 12 V - compatible with Li-ion (3.0–4.2 V), alkaline (2×AA), and industrial 5 V/12 V rails. |
| CMRR | 100 dB at 25°C - rejects common-mode noise in noisy industrial sensor environments. |
| PSRR | 100 dB at 25°C - maintains accuracy despite ripple on shared power rails. |
Pinout & Package
TLV2241CDG4 is housed in a 5-pin SOT-23 (DBV) package with exposed pad for thermal enhancement. The package measures 2.9 mm × 1.6 mm × 1.1 mm and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN− | Inverting input | High-impedance node (300 MΩ differential resistance); accepts signals up to VCC with rail-to-rail common-mode range. |
| 2 - IN+ | Non-inverting input | Matches IN− in bias current (≤550 pA) and offset; critical for precision instrumentation amplifier configurations. |
| 3 - VCC | Positive supply | Accepts 2.5–12 V; decoupling requires 0.1 µF ceramic capacitor placed ≤2.5 mm from pin. |
| 4 - GND | Ground reference | Low-inductance connection required; ground plane removal under inputs minimizes stray capacitance. |
| 5 - OUT | Amplifier output | Drives loads up to ±200 µA; rail-to-rail swing enables full-scale output into high-Z ADC inputs. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower operation | 1 µA/channel supply current - reduces system quiescent power by >90% vs. standard rail-to-rail op-amps. |
| Rail-to-rail input/output | Full 0 V to VCC input range and output swing within 180 mV of rails - preserves dynamic range in low-voltage systems. |
| Ultra-low input bias current | 100 pA typical at 25°C - enables use with 10 MΩ+ source impedances without significant offset drift. |
| Specified performance at 2.7 V | All key parameters (VIO, CMRR, PSRR, UGBW) guaranteed at 2.7 V - validates operation with depleted Li-ion cells. |
| Stable with capacitive loads | 60° phase margin at 100 pF load - eliminates need for isolation resistors in RC-filtered sensor interfaces. |

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 |
|---|---|---|---|
| TLV2401CDR | 0.88 µA supply current, 5 kHz GBW, 390 µV VIO, 2.5–16 V supply range | Higher supply voltage ceiling (16 V) but reduced phase margin with >50 pF loads | Preferred when wider supply range or lower offset is critical; verify stability with target capacitive load. |
| LPV821DBVR | 320 nA supply current, 6.5 kHz GBW, 125 µV VIO, 1.6–5.5 V supply range | Narrower supply range (max 5.5 V); superior offset and lower power, but incompatible with 12 V systems | Select for sub-1 µA ultra-low-power designs powered by 3.3 V or coin cells; not suitable for 12 V industrial use. |
Compared with TLV2241CDG4, TLV2401CDR offers higher supply voltage tolerance and slightly lower offset, while LPV821DBVR delivers significantly lower quiescent current and offset but sacrifices 12 V compatibility - making TLV2241CDG4 the optimal balance for 2.5–12 V micropower applications requiring proven stability and wide temperature support.

FAQ
What is the maximum operating temperature range for TLV2241CDG4?
The TLV2241CDG4 is rated for commercial-grade operation from 0°C to 70°C. Its absolute maximum junction temperature is 150°C, and thermal performance is characterized with θJA = 324.1°C/W on low-K test PCB - allowing safe operation at full ambient rating with appropriate board layout and minimal power dissipation.
Does TLV2241CDG4 support true rail-to-rail output swing?
Yes, TLV2241CDG4 delivers rail-to-rail output swing: at 50 µA load, VOH reaches within 180 mV of VCC and VOL stays within 180 mV of GND across 2.7 V, 5 V, and 12 V supplies. This is confirmed in the "Output Characteristics" table of the SLOS329C datasheet under both 2 µA and 50 µA load conditions.
Can TLV2241CDG4 drive capacitive loads without external compensation?
Yes, TLV2241CDG4 is stable with capacitive loads up to 100 pF, achieving 60° phase margin and 15 dB gain margin per Figure 24 and 25 in the datasheet. No series isolation resistor is required for typical RC-filtered sensor interfaces, simplifying layout and preserving signal integrity.
What is the input bias current specification for TLV2241CDG4 at 25°C?
The TLV2241CDG4 exhibits 100 pA typical input bias current at 25°C (TLV224xC grade), with a maximum of 550 pA across the full 0°C to 70°C range. This ultra-low value enables accurate amplification of signals from high-impedance sources such as pH electrodes and thermistors without significant voltage drop.
Is TLV2241CDG4 pin-compatible with other devices in the TLV224x family?
No - TLV2241CDG4 uses the 5-pin SOT-23 (DBV) package, while TLV2242 and TLV2244 use 8-pin MSOP and 14-pin TSSOP/SOIC packages respectively. Pinouts differ fundamentally: TLV2241CDG4 has dedicated IN+, IN−, VCC, GND, and OUT pins in compact layout, whereas multi-channel variants share power pins and require different routing.
