Product details
Overview
TLV2731IDBVTG4 from Texas Instruments is a single, rail-to-rail output, low-power LinCMOS™ operational amplifier in a 5-pin SOT-23 package. It delivers 2 MHz gain-bandwidth, 1.6 V/μs slew rate at 5 V, 15 nV/√Hz input voltage noise, 1 pA typical input bias current, and operates from 2.7 V to 10 V - optimized for low-voltage signal conditioning in battery-powered sensor interfaces.
For engineers reviewing the TLV2731IDBVTG4 datasheet, TLV2731IDBVTG4 pinout, TLV2731IDBVTG4 application, or TLV2731IDBVTG4 equivalent, key selection criteria include rail-to-rail output swing, micropower consumption (≤1.3 mA), high input impedance (>1 TΩ), low-noise performance at 1 kHz, and stable operation driving 600 Ω loads or capacitive loads with isolation resistor compensation.
Technical Context
The TLV2731IDBVTG4 employs a LinCMOS™ input stage enabling ultra-low input bias current (1 pA typ) and high common-mode input range extending to the negative rail. Its rail-to-rail output stage supports full dynamic range in single-supply systems, critical for interfacing with 3 V or 5 V ADCs without level-shifting.
It features internal compensation for unity-gain stability, achieves 48° phase margin into 600 Ω + 100 pF, and supports extended capacitive load drive via external RISO - making it suitable for reference buffers, piezoelectric transducer amplification, and MOSFET gate-driving circuits where precision and low quiescent current are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - enables direct use in 3 V and 5 V systems without regulation overhead |
| Gain-Bandwidth Product | 2 MHz at VDD = 5 V - supports audio-band and medium-speed sensor signal amplification |
| Slew Rate | 1.6 V/μs at VDD = 5 V - ensures faithful reproduction of fast transients up to ~300 kHz full-swing |
| Input Voltage Noise | 15 nV/√Hz at f = 1 kHz - minimizes added noise in high-impedance source amplification (e.g., piezo sensors) |
| Input Bias Current | 1 pA typical - preserves signal integrity in pH probes, photodiode, or MEMS sensor front-ends |
| Output Swing | Rail-to-rail - delivers full 0 V to VDD output range, maximizing ADC utilization in single-supply designs |
| Quiescent Current | 1.3 mA max at VDD = 5 V - enables multi-day operation in coin-cell–powered monitoring devices |
Pinout & Package
TLV2731IDBVTG4 is housed in a 5-pin SOT-23 (DBV) package measuring 2.9 mm × 2.8 mm, offering 66% board space reduction versus SOIC-8. The package is tape-and-reel only and rated for –40°C to +85°C industrial operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Amplifier output | Delivers rail-to-rail voltage swing; requires RISO ≥ 50 Ω for stable driving of >1 nF capacitive loads |
| 2: VDD+ | Positive supply | Highest potential supply pin; must be decoupled with 0.1 μF ceramic capacitor near pin |
| 3: IN+ | Noninverting input | High-impedance node (>1 TΩ); sensitive to PCB leakage - guard ring recommended |
| 4: IN− | Inverting input | Differential input node; matched layout critical for offset and CMRR performance |
| 5: VDD−/GND | Negative supply / ground | Reference return for all signals; low-impedance connection essential for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Enables full-scale signal capture in 3 V microcontroller ADCs without external level-shifting circuitry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 0.1 μV/°C offset drift vs TLV2731IDBVTG4's 0.5 μV/°C; higher 350 kHz GBW but lower 1.6 V/μs slew rate | Better for DC-critical sensor bridges; less suited for AC-coupled audio or fast transient response | Select OPA333AIDBVR when long-term offset stability dominates over bandwidth or slew rate |
| MCP6001T-E/OT | Lower 1 MHz GBW and 0.6 V/μs slew rate; 100 nA input bias current (vs 1 pA); same SOT-23-5 package and 1.8–6 V supply range | Cost-optimized for general-purpose buffering where ultra-low bias current is unnecessary | Select MCP6001T-E/OT for non-critical, high-volume consumer applications with relaxed noise and bias specs |
Compared with OPA333AIDBVR and MCP6001T-E/OT, TLV2731IDBVTG4 uniquely balances rail-to-rail output, 1 pA bias current, 2 MHz bandwidth, and micropower operation - making it optimal for battery-powered, high-impedance, medium-speed signal chains where zero-drift isn't required but LinCMOS™ precision is.

FAQ
What is the operating temperature range of the TLV2731IDBVTG4?
The TLV2731IDBVTG4 is specified for industrial operation from –40°C to +85°C. This rating is confirmed in the device information table and absolute maximum ratings section of the official datasheet (SLOS198B). The 'I' suffix in TLV2731IDBVTG4 explicitly denotes the extended temperature grade, distinguishing it from the commercial-grade TLV2731CDBVTG4 (0°C to 70°C). All electrical characteristics in the datasheet's Tables 5.4–5.7 are validated across this full –40°C to +85°C range.
Does the TLV2731IDBVTG4 support true rail-to-rail input?
No, the TLV2731IDBVTG4 does not support rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD−/GND) but stops 1.3 V below the positive rail (VDD+), as specified in Section 5.3 Recommended Operating Conditions. For example, at VDD = 5 V, the valid input range is 0 V to 3.7 V. Only the output is rail-to-rail. This limitation is inherent to its LinCMOS™ input stage design and is clearly documented in both the Features and Electrical Characteristics tables.
Can the TLV2731IDBVTG4 drive a 600 Ω load effectively?
Yes, the TLV2731IDBVTG4 is fully characterized driving a 600 Ω load, as stated in its Features list and verified in Sections 5.4 and 5.6. At VDD = 5 V, it delivers VOH ≥ 4.3 V and VOL ≤ 500 mV into 600 Ω, supporting telecom line-driver compliance. Its 1.6 V/μs slew rate and 2 MHz GBW ensure adequate settling for moderate-bandwidth signals. However, for sustained 600 Ω loading, thermal derating per Section 5.2 must be observed - maximum power dissipation drops to 78 mW at TA = 85°C.
What is the input offset voltage specification for TLV2731IDBVTG4?
The TLV2731IDBVTG4 has a maximum input offset voltage (VIO) of 3 mV over its full operating temperature range (–40°C to +85°C), with a typical value of 0.7 mV at 25°C. This is explicitly listed in Tables 5.4 (VDD = 3 V) and 5.6 (VDD = 5 V) of the datasheet. The 'I' grade shares identical offset specifications with the 'C' grade, differing only in temperature range and some min/max boundaries in other parameters like supply current.
Is the TLV2731IDBVTG4 pin-compatible with other SOT-23-5 op-amps?
The TLV2731IDBVTG4 uses the standard 5-pin SOT-23 (DBV) pinout: Pin 1 = OUT, Pin 2 = VDD+, Pin 3 = IN+, Pin 4 = IN−, Pin 5 = VDD−/GND. While physically compatible with other DBV-packaged op-amps, functional pin compatibility is not guaranteed - for example, OPA333AIDBVR uses the same pinout, but MCP6001T-E/OT reverses IN+ and IN−. Always verify pin function mapping against each device's datasheet; TLV2731IDBVTG4's pin functions are defined in Table 4-1 and Figure 4-1 of SLOS198B.
