Product details
Overview
TLV2721IDBVR from Texas Instruments is a single, rail-to-rail output, CMOS operational amplifier in SOT-23-5 package, designed for ultra-low-power (150 µA max), low-noise (38 nV/√Hz at 1 kHz), and high-input-impedance (10¹² Ω) signal conditioning in battery-powered systems. It operates from 2.7 V to 10 V, delivers ±500 µA output sink/source, and supports common-mode input down to the negative rail - ideal for interfacing with piezoelectric transducers and ADCs in remote sensing.
For engineers reviewing the TLV2721IDBVR datasheet, TLV2721IDBVR pinout, TLV2721IDBVR application, or TLV2721IDBVR equivalent, key selection criteria include its guaranteed –40°C to +85°C industrial temperature range, rail-to-rail output swing within 15 mV of rails (at 50 µA), 510 kHz gain-bandwidth product at 5 V, and compatibility with high-impedance sources requiring <1 pA input bias current.
Technical Context
The TLV2721IDBVR uses an advanced CMOS process to achieve rail-to-rail output swing while maintaining micropower operation and high DC precision. Its input stage features p-channel MOSFETs enabling common-mode voltage down to VDD– and input bias current as low as 1 pA (typical).
It is fully characterized across 3 V and 5 V supplies with specified performance over –40°C to +85°C (I-grade), including input offset voltage ≤ ±3 mV, PSRR ≥ 80 dB at 5 V, and CMRR ≥ 65 dB - making it suitable for precision analog front-ends where supply rejection and thermal stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-cell Li-ion, 3.3 V, and 5 V systems without level-shifting. |
| Quiescent Current | 100–150 µA (typ/max) - enables multi-year battery life in always-on sensor nodes. |
| Input Bias Current | ±1 pA (typ) - preserves signal integrity when amplifying from >1 GΩ sources (e.g., piezo sensors). |
| Input Voltage Noise | 38 nV/√Hz at 1 kHz - low enough for sub-mV signal amplification without dominating noise floor. |
| Output Swing | Within 12 mV of VDD– and 120 mV of VDD+ at 5 V / 500 µA load - maximizes dynamic range into ADCs. |
| Gain-Bandwidth Product | 510 kHz at 5 V - sufficient for anti-aliasing filters, sensor buffering, and slow-control loops. |
| Common-Mode Input Range | Extends to VDD– - allows direct sensing of ground-referenced signals without level shifters. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9 mm × 2.8 mm footprint, 5.6 mm² total area - occupies one-third the board space of SOIC-8, enabling placement adjacent to high-impedance sensors to minimize trace-induced noise pickup.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; capable of sourcing 1 mA / sinking 500 µA at 5 V. |
| 2 (V+) | Positive supply | Accepts 2.7–10 V; power supply rejection ≥ 80 dB ensures stable operation under noisy rails. |
| 3 (+IN) | Noninverting input | High-impedance (10¹² Ω) node; accepts common-mode voltages down to VDD–. |
| 4 (–IN) | Inverting input | Differential input pair node; matched to +IN for low offset and drift (±1 µV/°C). |
| 5 (V–) | Negative supply | Reference for dual-supply operation or ground in single-supply configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Enables full utilization of ADC input range in 3 V and 5 V systems, improving SNR by up to 12 dB vs. non-rail-to-rail op-amps. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2711IDBVR | Micropower variant (17 µA max); lower bandwidth (170 kHz) and higher input offset (±5 mV). | Better suited for ultra-long-life coin-cell applications where speed is secondary to current draw. | Choose TLV2711IDBVR only if supply current <20 µA is mandatory and GBW >200 kHz is unnecessary. |
| OPA316IDBVR | Higher speed (10 MHz GBW), lower noise (11 nV/√Hz), but higher quiescent current (400 µA). | Required for active filters or fast-settling data acquisition where TLV2721IDBVR's 510 kHz GBW is limiting. | Choose OPA316IDBVR when signal bandwidth exceeds 100 kHz and system power budget permits >3× higher IDD. |
Compared with TLV2721IDBVR, TLV2711IDBVR trades bandwidth and precision for extreme low power, while OPA316IDBVR delivers superior AC performance at the cost of 4× higher supply current - making TLV2721IDBVR the optimal balance for industrial sensor signal chains requiring <200 µA, <40 nV/√Hz, and rail-to-rail output.

FAQ
What is the operating temperature range of the TLV2721IDBVR?
The TLV2721IDBVR is rated for industrial operation from –40°C to +85°C, as confirmed by full electrical characterization across this range in the official TI datasheet (SLOS197B). This makes TLV2721IDBVR suitable for deployment in outdoor metering equipment, factory-floor transmitters, and automotive cabin-sensing modules where ambient extremes are expected.
Does the TLV2721IDBVR support true rail-to-rail input?
No - the TLV2721IDBVR features rail-to-rail *output* swing and common-mode input range extending to the negative rail (VDD–), but its positive common-mode limit is VDD–1.3 V (e.g., 3.7 V at 5 V supply). This is explicitly defined in Section 5.2 Recommended Operating Conditions and verified in Table 5-4 and 5-5 of the TLV2721IDBVR datasheet.
What is the maximum capacitive load the TLV2721IDBVR can drive stably?
The TLV2721IDBVR is characterized to drive >100 pF loads while maintaining ≥53° phase margin, as shown in Figures 5-27 and 5-28 of the datasheet. For loads exceeding 100 pF, adding a small series resistor (e.g., 100–500 Ω) at the output improves stability - a technique validated in TI's Application Note on capacitive load driving for the TLV2721IDBVR.
Is the TLV2721IDBVR pin-compatible with other SOT-23-5 op-amps like the TLV2711IDBVR?
Yes - TLV2721IDBVR shares identical SOT-23-5 (DBV) pinout (OUT, V+, +IN, –IN, V–) and footprint with TLV2711IDBVR and TLV2731IDBVR, enabling drop-in substitution in layouts where supply current, bandwidth, or noise requirements align. Pin compatibility is confirmed in TI's Package Mechanical Drawings and Pin Configuration section (Figure 4-1).
What is the typical input offset voltage drift of the TLV2721IDBVR over temperature?
The TLV2721IDBVR exhibits ±1 µV/°C typical input offset voltage drift across –40°C to +85°C, as specified in both 3 V and 5 V Electrical Characteristics tables (Sections 5.4 and 5.5). This low drift ensures minimal calibration drift in precision instrumentation using TLV2721IDBVR over wide ambient conditions.
