Product details
Overview
TLV2630IDBVR from Texas Instruments is a single-channel rail-to-rail output operational amplifier with shutdown, designed for low-voltage, high-speed signal conditioning in space-constrained systems. It operates from 2.7 V to 5.5 V, delivers 9 MHz gain-bandwidth, consumes only 730 µA per channel, and supports −40°C to 125°C industrial temperature range - enabling direct interface with Li-ion powered microcontrollers and data converters.
For engineers reviewing the TLV2630IDBVR datasheet, TLV2630IDBVR pinout, TLV2630IDBVR application, or TLV2630IDBVR equivalent, key selection criteria include its 6-pin SOT-23 package with integrated shutdown control, ground-referenced input range (VICR = GND to VDD−1 V), ultralow 4 µA shutdown current, and rail-to-rail output swing critical for precision analog front-ends in battery-powered instrumentation.
Technical Context
The TLV2630IDBVR implements a voltage-feedback op-amp architecture optimized for single-supply operation. Its input stage includes ground-sensing PNP differential pairs, enabling common-mode input down to GND, while the output stage uses complementary push-pull transistors to achieve rail-to-rail swing within 100 mV of each rail at 10 mA load.
It integrates an active shutdown function controlled by a logic-level SHDN pin (VIH ≥ 2 V, VIL ≤ 0.4 V), reducing supply current to 4 µA typical while maintaining fast turn-on (1.5 µs at VDD = 5 V) and turn-off (200 ns) times - essential for power-gated sensor interfaces and portable medical devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - compatible with single-cell Li-ion (3.0–4.2 V) and 3.3-V microcontroller I/O domains. |
| Gain-Bandwidth Product | 9 MHz - supports stable unity-gain buffer configurations up to ~9 MHz or closed-loop gains of 10 at ~900 kHz. |
| Supply Current (Active) | 730 µA per channel - enables >10-year battery life in always-on sensor nodes drawing <1 mA total system current. |
| Shutdown Current | 4 µA per channel - reduces quiescent power by 180×, enabling deep-sleep modes without external power switches. |
| Input Common-Mode Range | GND to VDD−1 V - allows direct connection to ground-referenced sensors (e.g., thermistors, bridge outputs) without level-shifting. |
| Output Swing (RL = 2 kΩ) | Within 100 mV of rails at 10 mA - preserves dynamic range in 3.3-V ADC drivers where full-scale is 0–3.3 V. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive, industrial motor control, and outdoor IoT edge nodes. |
Pinout & Package
SOT-23-6 (DBV) package: 2.9 mm × 1.6 mm × 1.45 mm body, 0.95 mm pin pitch, lead-free NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN− | Inverting Input | Differential input node; accepts signals up to VDD−1 V; requires stable bias path for DC-coupled applications. |
| 2 - IN+ | Non-Inverting Input | High-impedance input (1 pA typical bias current); supports ground-referenced sensor connections. |
| 3 - GND | Analog Ground Reference | Primary return path for input/output currents; must be connected to clean system AGND plane. |
| 4 - VDD | Positive Supply Rail | Accepts 2.7–5.5 V; bypass capacitor (0.1 µF ceramic) required within 5 mm of this pin. |
| 5 - SHDN | Active-Low Shutdown Control | Logic input: ≤0.4 V disables amplifier (4 µA IDD), ≥2 V enables (730 µA IDD); no pull-up required. |
| 6 - OUT | Amplifier Output | Rail-to-rail capable; drives 10 mA into 2 kΩ load; stable with 10 pF capacitive load per datasheet. |
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 |
|---|---|---|---|
| TLV2782IDGKR | Lower supply current (650 µA), lower GBW (8 MHz), no shutdown, 8-pin MSOP package. | Lacks shutdown control and rail-to-rail output (output swing limited to VDD−0.7 V), unsuitable for deep-sleep systems. | Select when ultra-low quiescent current is primary and shutdown functionality is handled externally. |
| OPA343UA/2K5 | Higher GBW (5.5 MHz), higher supply current (850 µA), rail-to-rail I/O, SOIC-8 package. | Wider input common-mode range (−0.3 V to VDD+0.3 V), but higher noise (25 nV/√Hz) and no shutdown pin. | Select when dual-supply compatibility or extended input range beyond GND is required, and PCB layout accommodates larger SOIC-8. |
Compared with TLV2782IDGKR and OPA343UA/2K5, the TLV2630IDBVR uniquely combines rail-to-rail output, ground-sensing input, integrated shutdown, and 9 MHz bandwidth in a 6-pin SOT-23 - making it optimal for miniaturized, battery-conscious signal chains where power cycling and full dynamic range are mandatory.

FAQ
What is the maximum capacitive load the TLV2630IDBVR can drive stably?
The TLV2630IDBVR is characterized for stability with up to 10 pF capacitive load when configured as a unity-gain buffer (AV = 1), per Figure 17 in the datasheet. Driving larger loads (e.g., >50 pF) requires isolation via a series resistor (≥100 Ω) between the TLV2630IDBVR output and the load capacitance to maintain phase margin above 50° and prevent oscillation.
Does the TLV2630IDBVR require external pull-up on the SHDN pin?
No, the TLV2630IDBVR SHDN pin has internal logic-level thresholds (VIH ≥ 2 V, VIL ≤ 0.4 V) and does not require an external pull-up resistor. When driven directly by a microcontroller GPIO, connecting SHDN to MCU VDD (≥2 V) enables the amplifier, and connecting to GND (≤0.4 V) places it in shutdown mode with 4 µA supply current.
Can the TLV2630IDBVR operate from a 1.8-V supply?
No, the TLV2630IDBVR has a minimum specified supply voltage of 2.7 V. Operation below 2.7 V is outside recommended conditions and may result in degraded parameters including reduced output swing, increased input offset voltage, and failure to meet rail-to-rail output specification. For 1.8-V systems, consider the TLV278x or TLV9001 families.
What is the typical input offset voltage of the TLV2630IDBVR at 25°C?
The typical input offset voltage of the TLV2630IDBVR at 25°C is 250 µV, with a maximum of 4500 µV over the full −40°C to 125°C temperature range. This value is measured under standard test conditions (VDD = 2.7 V or 5 V, VIC = VDD/2, VO = VDD/2) and reflects the device's precision performance in DC-coupled sensor interfaces.
Is the TLV2630IDBVR RoHS compliant and lead-free?
Yes, the TLV2630IDBVR is RoHS compliant and features a lead-free NiPdAu (nickel-palladium-gold) lead finish, as confirmed in TI's Package Option Addendum. It meets JEDEC MSL Level-1 (unlimited floor life at ≤30°C/60% RH) and is rated for peak reflow temperatures up to 260°C.
