Product details
Overview
TLV2221IDBVRG4 from Texas Instruments is a single rail-to-rail output, very low-power operational amplifier in 5-pin SOT-23 package, designed for battery-powered signal conditioning. It delivers 130µA typical supply current, 1.1MHz gain-bandwidth product, and ±10pA input bias current, enabling high-impedance sensor interfacing in handheld monitoring systems.
For engineers reviewing the TLV2221IDBVRG4 datasheet, TLV2221IDBVRG4 pinout, TLV2221IDBVRG4 application, or TLV2221IDBVRG4 equivalent, key selection criteria include its 2.7V–10V supply range, rail-to-rail output swing, 3mV max input offset voltage over –40°C to +85°C, and ultra-small SOT-23 footprint for space-constrained analog front-ends.
Technical Context
The TLV2221IDBVRG4 employs Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining low noise (30nV/√Hz at 1kHz) and ultra-low input bias current (±10pA). Its common-mode input voltage range includes the negative rail, supporting single-supply operation down to 2.7V.
It features a unity-gain stable architecture with 4.5V/µs slew rate and 1.1MHz gain-bandwidth product, optimized for precision DC-coupled amplification and low-frequency AC signal conditioning-particularly where power budget and PCB area are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 10V - supports direct integration into 3V and 5V battery-powered systems without level-shifting. |
| Quiescent Current | 130µA typical - enables multi-year operation on coin-cell batteries in remote-sensing nodes. |
| Input Offset Voltage | ±3mV max at +25°C - ensures <1mV error in 100mV full-scale sensor outputs without trimming. |
| Gain-Bandwidth Product | 1.1MHz - sufficient for anti-aliasing filters and sensor amplification up to ~100kHz. |
| Slew Rate | 4.5V/µs - supports clean 10kHz sine-wave amplification with <0.1% THD+N at AV=1. |
| Input Bias Current | ±10pA typical - preserves signal integrity when amplifying piezoelectric or pH electrode sources. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs referenced to same supply (e.g., 3V SAR ADC). |
Pinout & Package
TLV2221IDBVRG4 is housed in a 5-pin SOT-23 (DBV) package measuring 2.90mm × 1.60mm, occupying one-third the board area of an SOIC-8. The pinout is optimized for low-noise layout: IN+ and IN− are separated by GND to minimize coupling, and OUT/IN− share the same package end to simplify feedback routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN+ | Non-inverting input | High-impedance node (6TΩ common-mode RIN) for direct connection to high-Z sensors. |
| 2 - VDD−/GND | Ground or negative supply | Reference plane for both input common-mode range and output swing; must be low-impedance. |
| 3 - IN− | Inverting input | Feedback node; placed adjacent to OUT (Pin 4) to minimize parasitic inductance in closed-loop paths. |
| 4 - OUT | Amplifier output | Rail-to-rail capable (e.g., 2.97V at 3V supply, 4.75V at 5V supply with 500µA load). |
| 5 - VDD+ | Positive supply | Accepts 2.7V–10V; decoupling capacitor (0.1µF) required between Pin 5 and Pin 2 for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full supply-voltage dynamic range-critical for maximizing SNR when driving 12-bit+ ADCs directly. |
| Ultra-low input bias current | ±10pA typical enables accurate amplification of microamp-level currents from photodiodes or electrochemical cells. |
| Low-noise performance | 30nV/√Hz at 1kHz allows clean amplification of µV-level signals from thermocouples or strain gauges. |
| Single-supply optimization | Common-mode input range includes negative rail (GND), eliminating need for dual supplies in portable instrumentation. |
| Micro-power operation | 130µA quiescent current permits continuous sensing in energy-harvesting or battery-backed IoT edge nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power, rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6001T-E/OT | Higher input offset (1.5mV typ), lower GBW (1MHz), same SOT-23-5 package and 100µA supply current. | Less suitable for sub-mV precision DC amplification but adequate for general-purpose buffering. | Choose MCP6001T-E/OT for cost-sensitive designs where 1.5mV offset is acceptable and 1MHz GBW suffices. |
| OPA316IDBVR | Lower noise (11nV/√Hz), higher GBW (10MHz), 200µA supply current, same SOT-23-5 package. | Better for higher-frequency sensor signals (e.g., ultrasonic receivers), but consumes 1.5× more current. | Choose OPA316IDBVR when bandwidth and noise dominate over battery life-e.g., active filter stages. |
Compared with MCP6001T-E/OT and OPA316IDBVR, TLV2221IDBVRG4 uniquely balances ultra-low power (130µA), rail-to-rail output, and sub-3mV offset in a 5-pin SOT-23-making it optimal for long-life, precision, space-constrained analog sensing.

FAQ
What is the maximum operating temperature range for TLV2221IDBVRG4?
The TLV2221IDBVRG4 is rated for operation from –40°C to +85°C, making it suitable for industrial and automotive cabin environments. This extended temperature range is confirmed in the Recommended Operating Conditions table (Section 5.4) of the official datasheet, and applies to the 'I' grade variant denoted in the part number suffix.
Does TLV2221IDBVRG4 support true rail-to-rail input capability?
No, TLV2221IDBVRG4 provides rail-to-rail *output* swing only. Its common-mode input voltage range extends to the negative rail (GND) but stops 1.3V below the positive rail (e.g., 0V to 1.7V at 3V supply). This is explicitly specified in Section 5.4 under VIC and VICR parameters.
Can TLV2221IDBVRG4 drive capacitive loads directly?
TLV2221IDBVRG4 is not unity-gain stable with heavy capacitive loads. Datasheet Figure 5-52 shows phase margin degrades below 45° for CL > 100pF without isolation resistance. For loads >50pF, a series resistor (e.g., 50Ω) between OUT and the capacitor is recommended to ensure stability.
What is the typical input offset voltage drift over temperature for TLV2221IDBVRG4?
The TLV2221IDBVRG4 exhibits ±0.6µV/°C typical input offset voltage drift (αVIO), as specified in Sections 5.5 and 5.7. This low drift enables stable DC gain accuracy across –40°C to +85°C without recalibration in precision sensor systems.
Is TLV2221IDBVRG4 pin-compatible with other SOT-23 op-amps like TLV2371?
No-TLV2221IDBVRG4 uses a non-standard pinout: Pin 1 = IN+, Pin 2 = GND, Pin 3 = IN−, Pin 4 = OUT, Pin 5 = VDD+. In contrast, TLV2371 (SOT-23-6) has different pin count and assignment. Direct replacement requires PCB redesign; always verify pin functions using Table 4-1 in the TLV2221 datasheet.
