Product details
Overview
TLV2624IPWG4 from Texas Instruments is a quad-channel, rail-to-rail output CMOS operational amplifier optimized for single-supply operation from 2.7 V to 5.5 V. It delivers 11 MHz gain-bandwidth, 10 V/µs slew rate, 27 nV/√Hz input voltage noise, and ultralow 4 µA/channel shutdown current - enabling high-resolution data acquisition in space-constrained industrial sensor front-ends and battery-powered instrumentation.
For engineers reviewing the TLV2624IPWG4 datasheet, TLV2624IPWG4 pinout, TLV2624IPWG4 application, or TLV2624IPWG4 equivalent, this page provides verified package mapping (TSSOP-14), confirmed quad-channel shutdown control architecture, rail-to-rail output swing down to 2.7 V, and validated alternatives for low-power precision signal conditioning.
Technical Context
The TLV2624IPWG4 implements a CMOS input stage with common-mode input range extending to VDD + 0.2 V and rail-to-rail output swing, supporting direct interfacing to positive-rail-referenced sensors and ADC drivers. Its 11-MHz unity-gain bandwidth and 10-V/µs slew rate are sustained across the full –40°C to +125°C industrial temperature range at only 800 µA per channel.
Shutdown is controlled via two dedicated pins: Pin 8 (1/2SHDN) disables channels 1 and 2; Pin 9 (3/4SHDN) disables channels 3 and 4. Each channel achieves 4 µA supply current in shutdown mode, with turnon/turnoff times of 4.5 µs (VDD = 2.7 V) and 200 ns respectively - critical for dynamic power management in portable systems.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-power precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2624IPWR | Same die, identical electrical specs, TSSOP-14 tape-and-reel (2000 pcs/reel) vs. tube (90 pcs/tube) packaging. | No functional difference - selected for automated SMT assembly vs. prototyping/hand-soldering. | Choose TLV2624IPWR for volume production; TLV2624IPWG4 for evaluation or low-volume builds. |
| OPA2333PWR | Zero-drift architecture (0.02 µV/°C offset drift), lower 1/f noise, but 350-µA/channel supply current and 350-kHz GBW. | Better DC precision for weigh scales or medical ECG; insufficient bandwidth for >10-kHz signal paths. | Select OPA2333PWR only when sub-µV offset stability dominates over speed and power; not drop-in for TLV2624IPWG4. |
Compared with TLV2624IPWR, TLV2624IPWG4 offers identical performance in a tube-packaged variant suited for lab validation and small-batch integration; versus OPA2333PWR, it trades ultra-low drift for 31× higher bandwidth and 2.3× lower quiescent power - making it optimal for wideband, battery-sensitive applications.

FAQ
What is the maximum load capacitance the TLV2624IPWG4 can drive while maintaining stability?
The TLV2624IPWG4 maintains ≥63° phase margin with 10-pF capacitive load at unity gain (RL = 2 kΩ). For loads >100 pF, external isolation resistor (≥100 Ω) is required between output and capacitor to prevent peaking or oscillation - confirmed in Figure 16 of the SLOS251D datasheet.
Does the TLV2624IPWG4 support true single-supply operation with input signals beyond the positive rail?
Yes. The TLV2624IPWG4's input common-mode range extends to VDD + 0.2 V, enabling direct connection to overvoltage-tolerant sensors (e.g., 5-V-output Hall sensors on 4.5-V rails) without external clamping diodes or level shifters - a key feature documented in the "VICR" specification row.
How does the shutdown functionality of the TLV2624IPWG4 differ from standard single-channel op-amps?
The TLV2624IPWG4 integrates two independent shutdown controls: Pin 8 (1/2SHDN) disables Channels 1 and 2; Pin 9 (3/4SHDN) disables Channels 3 and 4. This allows partial channel activation - e.g., keeping Channels 1–2 active for real-time monitoring while shutting down Channels 3–4 during idle periods - reducing system power without full IC disable.
What is the typical input offset voltage drift over temperature for the TLV2624IPWG4?
The TLV2624IPWG4 exhibits a typical input offset voltage drift of 3 µV/°C across –40°C to +125°C, with a maximum drift of 10 µV/°C. This value is explicitly listed in the "Temperature coefficient of input offset voltage (αVIO)" parameter row of the Electrical Characteristics table.
Can the TLV2624IPWG4 be used in a unity-gain stable configuration driving a 10-kΩ load?
Yes. The TLV2624IPWG4 is unity-gain stable with RL ≥ 2 kΩ and CL ≤ 10 pF, delivering 11 MHz bandwidth and 63° phase margin. Driving a pure 10-kΩ resistive load (no capacitance) is fully supported and improves phase margin further - verified in Figure 11 (AVD vs frequency) and Table "Phase margin".
