Product details
Overview
TLV2631IDBVT from Texas Instruments is a single-channel, rail-to-rail output operational amplifier optimized for low-voltage, high-speed signal conditioning in battery-powered systems. It delivers 9 MHz gain-bandwidth, 730 µA supply current per channel, rail-to-rail output swing, and ground-sensing input (VICR = GND to VDD−1 V) across −40°C to 125°C. It is used in precision analog front-ends for data converters and sensor interfaces in portable instrumentation.
For engineers reviewing the TLV2631IDBVT datasheet, TLV2631IDBVT pinout, TLV2631IDBVT application, or TLV2631IDBVT equivalent, key selection criteria include its 2.7–5.5 V supply range, 9 MHz bandwidth at ultralow quiescent current, industrial temperature rating, SOT-23-5 package footprint, and compatibility with Li-ion powered microcontroller systems such as MSP430.
Technical Context
The TLV2631IDBVT employs a CMOS input stage enabling picoampere-level input bias current (1–50 pA typ), combined with a high-gain, unity-gain stable internal architecture delivering 9 MHz GBW and 9.5 V/µs negative slew rate. Its rail-to-rail output stage supports full dynamic range utilization down to 2.7 V supply, while the ground-inclusive common-mode input range allows direct interfacing with single-supply, ground-referenced sensors and DACs.
No shutdown function is integrated - unlike the TLV2630/3/5 variants - making it suitable for always-on, low-latency signal paths where power-down sequencing is unnecessary. The device maintains 67–74 dB CMRR and 70–90 dB PSRR over frequency, supporting robust operation in mixed-signal environments with shared supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 9 MHz - enables stable unity-gain buffer or gain-of-10 amplification up to ~900 kHz without phase margin degradation. |
| Supply Current per Channel | 730 µA - supports continuous operation in sub-1 mA system power budgets, e.g., handheld medical sensors. |
| Input Voltage Range | GND to VDD−1 V - accepts ground-referenced inputs (e.g., thermistor dividers, resistive bridge outputs) without level-shifting. |
| Output Swing | Rail-to-rail - delivers >99% of full-scale output voltage headroom, maximizing ADC input utilization in 12-bit+ systems. |
| Supply Voltage Range | 2.7 V to 5.5 V - matches lithium-ion cell discharge curve and interfaces directly with 3.3 V or 5 V microcontrollers. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive, industrial motor control, and outdoor IoT edge nodes. |
| Equivalent Input Noise | 50 nV/√Hz @ 1 kHz - preserves SNR in low-level signal amplification (e.g., piezoelectric sensor preamps). |
Pinout & Package
SOT-23-5 (DBV) package: 2.9 mm × 1.6 mm × 1.45 mm body, surface-mount, lead-free (NiPdAu), moisture sensitivity level 1, rated for reflow up to 260°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 - IN+ | Non-inverting input | Ground-referenced input capable of operating at 0 V common-mode voltage. |
| 3 - GND | Analog ground reference | Primary return path for input bias current and output load current; must be low-impedance. |
| 4 - VDD | Positive supply rail | Accepts 2.7–5.5 V; decoupling capacitor (0.1 µF ceramic) required within 2 mm of this pin. |
| 5 - OUT | Amplifier output | Capable of sourcing/sinking ±28 mA (VDD = 5 V); drives 2 kΩ loads with <0.1% THD+N at 10 kHz. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA343UA | Higher supply current (850 µA), lower GBW (5.5 MHz), wider VICR (−0.3 V to VDD+0.3 V), no rail-to-rail output. | Less suitable for battery-constrained designs requiring full output swing; better for dual-supply or offset-tolerant inputs. | Select OPA343UA only when input voltage may go slightly below ground or when higher input voltage range outweighs output swing loss. |
| TLV2782CDR | Lower supply voltage (1.8–3.6 V), lower GBW (8 MHz), lower noise (9 nV/√Hz), rail-to-rail I/O, but limited to 3.6 V max. | Optimized for ultra-low-voltage MCUs (e.g., MSP430FRxx), not compatible with 5 V systems or 125°C operation. | Choose TLV2782CDR for sub-3.6 V applications where noise dominates over bandwidth; avoid for 5 V or extended temperature use. |
Compared with OPA343UA and TLV2782CDR, TLV2631IDBVT uniquely balances 9 MHz bandwidth, rail-to-rail output, ground-sensing input, and 125°C operation within a 730 µA budget - making it the only option among the three qualified for high-fidelity, high-temperature, single-supply sensor signal chains.

FAQ
What is the maximum recommended supply voltage for TLV2631IDBVT?
The absolute maximum supply voltage for TLV2631IDBVT is 6 V, but the recommended operating range is strictly 2.7 V to 5.5 V. Exceeding 5.5 V risks parametric shift or reliability degradation, especially at high temperature. At 5.5 V, the device delivers full rail-to-rail output swing and maintains 9 MHz GBW, making it ideal for 5 V microcontroller interfaces.
Does TLV2631IDBVT include a shutdown pin?
No, TLV2631IDBVT does not include a shutdown pin. It is the non-shutdown variant of the TLV263x family - distinct from TLV2630IDBVT (6-pin SOT-23 with SHDN) and TLV2633IDGS (10-pin MSOP with SHDN). This simplifies PCB layout and eliminates control logic overhead in always-on signal paths, such as analog sensor buffers or ADC drivers.
What is the typical input offset voltage of TLV2631IDBVT at room temperature?
The typical input offset voltage of TLV2631IDBVT is 250 µV at 25°C, with a maximum of 4500 µV over the full −40°C to 125°C range. Its temperature coefficient is 3 µV/°C, meaning offset drift remains predictable and bounded - critical for DC-coupled applications like precision weigh scales or strain gauge amplifiers where calibration stability matters.
Can TLV2631IDBVT drive a 2 kΩ load with low distortion?
Yes, TLV2631IDBVT drives a 2 kΩ load with 0.003% THD+N at 10 kHz (AV = 1), 0.02% at AV = 10, and 0.095% at AV = 100. This performance is verified at VDD = 5 V and VO(PP) = VDD/2. Combined with 9.5 V/µs slew rate and 9 MHz GBW, it supports high-fidelity buffering of audio, ultrasound, and data converter reference signals without harmonic corruption.
Is TLV2631IDBVT compatible with standard SOT-23-5 PCB footprints and reflow profiles?
Yes, TLV2631IDBVT uses the industry-standard SOT-23-5 (DBV) package with JEDEC MO-178 compliance. Its land pattern matches IPC-7351 recommendations, and it is rated MSL Level-1 with peak reflow tolerance up to 260°C. The device's 1.45 mm max height and 0.95 mm pin pitch ensure compatibility with automated placement and standard convection reflow profiles.
