Product details
Overview
TLV2630IDR from Texas Instruments is a single-channel rail-to-rail output operational amplifier with ground-sensing input (VICR includes GND), 9 MHz gain-bandwidth product, 730 µA supply current per channel, and operation from 2.7 V to 5.5 V over −40°C to 125°C. It features ultralow-power shutdown mode (4 µA/channel) and is optimized for high-resolution data converter interfaces in Li-ion–powered systems.
For engineers reviewing the TLV2630IDR datasheet, TLV2630IDR pinout, TLV2630IDR application, or TLV2630IDR equivalent, this page delivers verified electrical specs, SOT-23-6 package mapping, real-world use cases in precision analog front-ends, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLV2630IDR employs a CMOS input stage enabling rail-to-rail output swing and ground-referenced common-mode input range (GND to VDD−1 V). Its 9 MHz GBW is achieved at only 730 µA supply current, supporting unity-gain stable operation with load capacitance up to 50 pF.
It integrates an active shutdown control pin (SHDN) that reduces supply current to 4 µA/channel while maintaining fast enable/disable timing (ton = 1.5 µs at VDD = 5 V). Input offset voltage is specified at 4500 µV max over full temperature range, with 3 µV/°C drift coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 9 MHz - supports stable unity-gain buffer or 2× inverting amplifier up to ~4.5 MHz without phase margin degradation |
| Supply current per channel | 730 µA - enables battery-powered designs with >1000-hour runtime on coin-cell or single Li-ion cell |
| Rail-to-rail output swing | VOH ≥ 4.9 V, VOL ≤ 0.08 V at VDD = 5 V and IO = 1 mA - maximizes dynamic range into ADC reference rails |
| Input common-mode range | GND to VDD−1 V - allows direct interface to ground-referenced sensors and DAC outputs |
| Shutdown supply current | 4 µA/channel - reduces system standby power by >99% vs active mode, critical for duty-cycled signal chains |
| Operating temperature | −40°C to 125°C - qualified for industrial motor control, automotive cabin electronics, and outdoor instrumentation |
| Equivalent input noise | 50 nV/√Hz at 1 kHz - preserves SNR in 16-bit+ SAR ADC driver applications with bandwidth <100 kHz |
Pinout & Package
SOT-23-6 package (DBV), 1.45 mm max height, 2.9 mm × 1.6 mm footprint, thermal pad optional (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN− | Inverting input | Differential input node; high-impedance CMOS input (IIB = 1 pA typ) for precision feedback networks |
| 2 - IN+ | Non-inverting input | Reference or sensor input node; supports common-mode voltages down to GND |
| 3 - OUT | Amplifier output | Capable of sourcing/sinking ±28 mA at VDD = 5 V; rail-to-rail swing enables full-scale ADC utilization |
| 4 - GND | Analog ground | Primary return path for input bias currents and output load; must be low-impedance connection to system AGND |
| 5 - SHDN | Shutdown control | Active-low logic input; drives to <0.4 V to enter shutdown (IDD = 4 µA); >2 V to enable normal operation |
| 6 - VDD | Positive supply | Single-supply input: 2.7 V to 5.5 V; compatible with MSP430 microcontrollers and Li-ion battery discharge profile |
Key Features
| Feature | Design Value |
|---|---|

| Ground-sensing input | Accepts signals from 0 V (e.g., thermistor dividers, current-sense amps), eliminating need for negative supply or level shifters |
| Ultralow shutdown current | 4 µA/channel enables micro-power sleep modes in portable data loggers and wireless sensor nodes |
| Wide supply range | 2.7 V to 5.5 V operation matches lithium-ion battery voltage (4.2 V → 2.7 V) and 3.3 V/5 V system rails |
| High-speed, low-power | 9 MHz GBW at 730 µA achieves 12.3 MHz/mA efficiency-superior to most micropower op-amps in its class |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2631IDBVR | No shutdown pin (5-pin SOT-23); identical GBW, supply current, and input/output specs | Used where continuous operation is required and PCB space is constrained (5-pin vs 6-pin) | Select when shutdown functionality is unnecessary and minimal footprint is prioritized |
| OPA343UA | Higher supply current (850 µA), wider VICR (−0.3 V to VDD+0.3 V), lower GBW (5.5 MHz) | Better for rail-splitting or dual-supply designs; less suitable for ultra-low-power battery operation | Choose when extended input range beyond rails is needed and 3.5 MHz bandwidth suffices |
Compared with TLV2630IDR, TLV2631IDBVR removes shutdown capability to save one pin and board area but retains identical analog performance; OPA343UA trades 15% higher quiescent current for enhanced input voltage range and robustness in mixed-supply systems.

FAQ
What is the maximum recommended supply voltage for TLV2630IDR?
The absolute maximum supply voltage for TLV2630IDR is 6 V, but the recommended operating range is 2.7 V to 5.5 V. Operating above 5.5 V risks permanent damage and violates TI's specified conditions. At 5.5 V, the device delivers full rail-to-rail output swing and maintains 9 MHz GBW while staying within thermal limits for the SOT-23-6 package.
Does TLV2630IDR support true ground-referenced input signals?
Yes, TLV2630IDR supports common-mode input voltages from GND to VDD−1 V. This allows direct connection of 0 V–referenced sources such as resistive temperature detectors (RTDs), thermistors, and current-sense amplifiers without external level-shifting circuitry. The input stage uses CMOS technology to achieve this ground-sensing capability with only 1 pA typical input bias current.
How does the shutdown feature of TLV2630IDR behave during power-up?
TLV2630IDR powers up enabled by default: when VDD reaches >2 V and SHDN is left unconnected or pulled high (>2 V), the amplifier operates normally. To ensure defined startup behavior, tie SHDN to VDD through a pull-up resistor. The turn-on time is 1.5 µs (at VDD = 5 V), measured from SHDN rising past 2 V to supply current reaching 50% of 730 µA.
Can TLV2630IDR drive a 10 kΩ load while maintaining rail-to-rail output?
Yes, TLV2630IDR delivers rail-to-rail output swing into 10 kΩ loads across its full temperature range. At VDD = 5 V and TA = 25°C, VOH ≥ 4.92 V and VOL ≤ 0.025 V at 1 mA load. With 10 kΩ, output current is <0.5 mA, well within the ±28 mA sourcing/sinking capability, ensuring <10 mV headroom from each rail under all operating conditions.
Is TLV2630IDR suitable for driving SAR ADC inputs in precision measurement systems?
Yes, TLV2630IDR is specifically designed for high-resolution data converter interfaces. Its 50 nV/√Hz input noise, 9 MHz GBW, and low distortion (0.003% THD+N at 10 kHz) ensure minimal SNR degradation when driving 16-bit SAR ADCs. Combined with rail-to-rail output and ground-sensing input, it eliminates external bias components and simplifies anti-alias filter design for DC–100 kHz signal chains.
