Product details
Overview
TLV2620IDR from Texas Instruments is a single-channel, rail-to-rail output CMOS operational amplifier with shutdown, designed for low-power, wide-bandwidth signal conditioning in single-supply systems. It delivers 11 MHz gain-bandwidth, 10 V/µs slew rate, 27 nV/√Hz input voltage noise, 800 µA supply current per channel, and operates from 2.7 V to 5.5 V over –40°C to +125°C - ideal for precision sensor front-ends and portable data acquisition.
For engineers reviewing the TLV2620IDR datasheet, TLV2620IDR pinout, TLV2620IDR application, or TLV2620IDR equivalent, key selection criteria include its rail-to-rail output swing, positive-rail-inclusive input common-mode range (1 V to VDD + 0.2 V), ultralow 4 µA shutdown current, and SOIC-8 package compatibility with industrial-grade thermal and ESD robustness requirements.
Technical Context
The TLV2620IDR employs a CMOS input stage enabling rail-to-rail output swing and VICR extending to the positive supply rail, supporting direct interfacing with ADC reference buffers and high-side sensing circuits. Its 11-MHz unity-gain bandwidth and 10-V/µs slew rate are achieved at only 800 µA supply current, balancing speed and power efficiency for battery-operated instrumentation.
Internal shutdown logic asserts when SHDN pin voltage falls below 0.4 V, reducing supply current to 4 µA per channel while maintaining fast turn-on (4.5 µs at 2.7 V) and turn-off (200 ns) times. The device is specified across the full industrial temperature range (–40°C to +125°C) with guaranteed performance under 2.7-V minimum supply - enabling use with Li-ion cells and MSP430 microcontrollers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports single-cell Li-ion (3.0–3.7 V nominal) and 3.3-V/5-V system rails without level-shifting. |
| Gain-Bandwidth Product | 11 MHz - enables stable unity-gain buffer operation up to ~10 MHz with minimal phase margin degradation. |
| Slew Rate | 10 V/µs - supports clean 1-Vpp output transitions at ≥1 MHz without slewing distortion in active filters or driver stages. |
| Input Noise Voltage | 27 nV/√Hz at 10 kHz - ensures <0.02% THD+N in 16-bit SAR ADC front-ends with ≤10-kΩ source impedances. |
| Shutdown Current | 4 µA per channel - reduces system standby power by >99% versus active mode, critical for duty-cycled sensor nodes. |
| Input Common-Mode Range | 1 V to VDD + 0.2 V - allows direct connection to VDD-referenced sensors (e.g., bridge amplifiers, DAC outputs) without external biasing. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial motor control, and outdoor IoT edge nodes. |
Pinout & Package
TLV2620IDR is housed in an 8-pin SOIC (D) package with 1.27-mm pitch, RoHS-compliant NiPdAu lead finish, and MSL Level-1 rating. Pin 1 is located at the top-left corner adjacent to the molded dot indicator.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - rail-to-rail capable, drives 2-kΩ loads with <10-mV headroom at VDD = 2.7 V. |
| 2 | IN− | Inverting input - high-impedance CMOS node (IIB = 2 pA typ), compatible with high-Z feedback networks. |
| 3 | IN+ | Non-inverting input - accepts common-mode voltages up to VDD + 0.2 V, enabling VDD-referenced signal routing. |
| 4 | GND | Analog ground reference - must be tied directly to low-impedance PCB ground plane to minimize PSRR degradation. |
| 5 | SHDN | Active-low shutdown control - pulls to GND (≤0.4 V) to enter 4-µA shutdown; floats or ties to VDD for normal operation. |
| 6 | VDD | Positive supply - decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for stability at 11 MHz. |
| 7 | NC | No internal connection - left unconnected; no routing or grounding required. |
| 8 | NC | No internal connection - left unconnected; no routing or grounding required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 10 mV of VDD and GND at 2.7 V supply and 2-kΩ load - eliminates need for dual supplies in precision buffering. |
| Positive-rail-inclusive input range | Accepts inputs up to VDD + 0.2 V - enables direct interface with DACs, voltage references, and high-side current-sense amplifiers. |
| Ultralow shutdown current | 4 µA per channel - extends battery life in intermittent-sampling applications such as environmental monitors and wearables. |
| Wide bandwidth at low power | 11 MHz GBW at 800 µA - achieves 10× higher speed-per-mA than legacy micropower op-amps like TLC27L2. |
| Industrial temperature grade | Specified from –40°C to +125°C - ensures parametric stability in engine control units, solar inverters, and factory automation PLCs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2621IDR | 5-pin SOT-23 variant with identical electrical specs but no SHDN pin and no NC pins - smaller footprint, no shutdown capability. | Used where board space is constrained and always-on operation is acceptable; not suitable for power-gated systems. | Select TLV2621IDR only if shutdown functionality is unnecessary and PCB real estate is premium. |
| OPA320AIDR | Lower input offset (150 µV max vs. 3500 µV), lower noise (7 nV/√Hz), but higher supply current (1.8 mA) and no shutdown - optimized for precision, not power. | Preferred in high-accuracy weigh scales or medical diagnostics where offset drift dominates error budget. | Choose OPA320AIDR when absolute DC accuracy outweighs battery life; TLV2620IDR remains optimal for low-power, wideband trade-offs. |
Compared with TLV2621IDR, TLV2620IDR adds active shutdown and two NC pins for layout flexibility in SOIC-8 footprints; compared with OPA320AIDR, it trades 2.25× lower quiescent current and integrated shutdown for higher offset and noise - making TLV2620IDR the balanced choice for industrial sensor interfaces requiring both speed and energy efficiency.

FAQ
What is the maximum recommended supply voltage for TLV2620IDR?
The absolute maximum supply voltage for TLV2620IDR is 6 V, but the recommended operating range is 2.7 V to 5.5 V. Exceeding 5.5 V risks parametric degradation or permanent damage. At 5.5 V, the device maintains full rail-to-rail output swing and meets all specifications across –40°C to +125°C, making it compatible with regulated 5-V rails and fully charged Li-ion cells (up to 4.2 V).
Does TLV2620IDR support rail-to-rail input operation?
TLV2620IDR does not support rail-to-rail input - its common-mode input voltage range is specified from 1 V to VDD + 0.2 V. While the upper limit extends beyond VDD, the lower limit stops at 1 V above GND. This design enables robust operation with VDD-referenced sources but requires external biasing for true GND-referenced signals. Input bias current remains ultra-low (2 pA typ) across this range.
How does the shutdown function behave on TLV2620IDR?
TLV2620IDR enters shutdown when the SHDN pin voltage is ≤0.4 V (VIL), reducing supply current to 4 µA per channel. During shutdown, the output is high-impedance - not clamped or driven. Turn-on time is 4.5 µs at 2.7 V, and turn-off time is 200 ns. The SHDN pin has no internal pull-up; external logic or microcontroller GPIO must actively drive it low to engage shutdown.
What is the typical phase margin of TLV2620IDR under standard test conditions?
Under standard test conditions (RL = 2 kΩ, CL = 10 pF, VDD = 2.7 V or 5 V, TA = 25°C), TLV2620IDR exhibits a typical phase margin of 63°, as confirmed by the differential voltage amplification and phase vs. frequency plot in the datasheet. This margin ensures stable unity-gain operation with minimal peaking and adequate step response fidelity for most closed-loop configurations.
Is TLV2620IDR pin-compatible with other members of the TLV262x family?
TLV2620IDR (SOIC-8) is not pin-compatible with TLV2621IDR (SOIC-8), despite shared package type - TLV2621IDR lacks SHDN and NC pins, assigning pins 5 and 7 to IN+ and OUT respectively. It is also incompatible with TLV2622IDR (dual, SOIC-8) and TLV2624IDR (quad, SOIC-14). Pin compatibility exists only within same-channel-count variants sharing identical pinout diagrams - verify against TI's official TLV262X PACKAGE PINOUTS figure before substitution.
