Product details
Overview
TLV2624ID 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, targeting high-resolution data acquisition and battery-powered signal conditioning.
For engineers reviewing the TLV2624ID datasheet, TLV2624ID pinout, TLV2624ID application, or TLV2624ID equivalent, this page provides verified package mapping (SOIC-14), confirmed quad-channel shutdown control architecture, industrial-grade (-40°C to 125°C) performance specs, and real-world design trade-offs versus alternative low-power op-amps.
Technical Context
The TLV2624ID implements a CMOS input stage with rail-to-rail output swing and a common-mode input range extending to VDD + 0.2 V - enabling direct interfacing with positive-rail-referenced sensors and ADC drivers. Its 11-MHz unity-gain bandwidth is achieved at only 800 µA per channel, maintaining phase margin ≥63° into 10-pF loads.
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 exhibits matched AC performance, with <0.095% THD+N at 10 kHz and 2.7-V supply, supporting precision analog front-ends in multichannel systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multichannel signal conditioning without discrete op-amp duplication. |
| Supply Voltage Range | 2.7 V to 5.5 V - compatible with Li-ion cells and MSP430 microcontrollers, eliminating level-shifting needs. |
| Gain-Bandwidth Product | 11 MHz - supports stable unity-gain buffer configurations up to ~10 MHz with minimal phase lag. |
| Slew Rate | 10 V/µs - ensures faithful reproduction of fast transients in sensor amplification and DAC output buffering. |
| Input Voltage Noise | 27 nV/√Hz at 10 kHz - critical for preserving SNR in 16-bit+ data converter interfaces. |
| Shutdown Current | 4 µA per channel - reduces system standby power by >99% versus active mode (800 µA/ch). |
| Operating Temperature | -40°C to 125°C - qualified for automotive cabin, industrial motor control, and outdoor instrumentation. |
Pinout & Package
TLV2624ID is housed in a 14-pin SOIC (D) package with 1.27-mm pitch, 8.65-mm body width, and RoHS-compliant NiPdAu lead finish. The package supports standard reflow profiles (MSL Level-1, 260°C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of amplifier channel 1 - rail-to-rail swing supports full dynamic range utilization. |
| 2 | 1IN− | Inverting input of channel 1 - high-impedance CMOS node (100 GΩ) minimizes loading on preceding stages. |
| 3 | 1IN+ | Non-inverting input of channel 1 - accepts common-mode voltages up to VDD + 0.2 V for rail-referenced sensing. |
| 4 | VDD | Positive supply rail - shared across all four amplifiers; decoupling required within 1 cm. |
| 5 | 2IN+ | Non-inverting input of channel 2 - electrically isolated from other inputs to prevent crosstalk-induced errors. |
| 6 | 2IN− | Inverting input of channel 2 - matched bias current (<50 pA) ensures low offset drift in differential configurations. |
| 7 | 2OUT | Output of amplifier channel 2 - independently buffered; no internal connection to channel 1 output. |
| 8 | 1/2SHDN | Shutdown control for channels 1 and 2 - logic-low (<0.4 V) disables both; high-Z state maintains default operation. |
| 9 | 3/4SHDN | Shutdown control for channels 3 and 4 - independent of Pin 8, enabling selective channel power gating. |
| 10 | GND | Analog ground reference - must be tied to system AGND plane with low-inductance path to minimize noise coupling. |
| 11 | 3IN+ | Non-inverting input of channel 3 - identical electrical characteristics to Pins 3 and 5 for consistent multichannel design. |
| 12 | 3IN− | Inverting input of channel 3 - supports matched resistor networks for precision instrumentation amplifier topologies. |
| 13 | 4IN− | Inverting input of channel 4 - fully specified over -40°C to 125°C, ensuring thermal stability in harsh environments. |
| 14 | 4OUT | Output of amplifier channel 4 - capable of sourcing/sinking ±28 mA, driving 2-kΩ loads to rail with <0.1 V error. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel, low-power, rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2624IPW | TSSOP-14 package (4.4 mm × 5 mm), 0.65-mm pitch - 45% smaller footprint than SOIC-14 but requires finer-pitch assembly. | Better suited for space-constrained portable designs; thermal resistance θJA = 173.6°C/W vs. SOIC's 122.3°C/W. | Select TLV2624IPW when board area is critical and reflow capability supports TSSOP; use TLV2624ID for legacy SOIC-compatible layouts and higher thermal mass. |
| TLV2634ID | Lower bandwidth (10 MHz), lower slew rate (9 V/µs), and reduced input voltage range (GND to VDD − 0.8 V) - trades speed for improved input stage robustness. | Preferred in high-noise industrial environments where input overvoltage tolerance outweighs bandwidth needs. | Choose TLV2634ID if common-mode transients exceed VDD + 0.2 V; otherwise, TLV2624ID delivers superior AC performance at identical quiescent current. |
Compared with TLV2624IPW, TLV2624ID offers higher thermal mass and easier hand-soldering, while TLV2634ID sacrifices bandwidth and rail-in capability for enhanced input fault protection - making TLV2624ID optimal for high-fidelity, wide-dynamic-range signal chains requiring full VDD-referenced input support.

FAQ
What is the maximum recommended supply voltage for TLV2624ID?
The absolute maximum supply voltage for TLV2624ID is 6 V, but the recommended operating range is strictly 2.7 V to 5.5 V. Exceeding 5.5 V risks permanent damage to the CMOS input stage and violates the device's qualified specifications. At 5.5 V, all parameters - including 11-MHz GBW and 10 V/µs slew rate - remain fully guaranteed across the -40°C to 125°C temperature range.
Does TLV2624ID support true rail-to-rail input operation?
TLV2624ID features rail-to-rail *output* swing but not rail-to-rail *input*. Its common-mode input voltage range extends from 1 V above GND to VDD + 0.2 V - meaning it accepts signals referenced to the positive rail (e.g., VDD-based voltage dividers), but does not accept signals at GND. This architecture optimizes input stage headroom and noise performance while enabling unique single-supply sensor interfacing.
How are the shutdown pins configured on TLV2624ID?
TLV2624ID uses two dedicated shutdown pins: Pin 8 (1/2SHDN) controls amplifiers 1 and 2; Pin 9 (3/4SHDN) controls amplifiers 3 and 4. A logic-low voltage (<0.4 V) on either pin reduces the corresponding channel's supply current to 4 µA. Both pins default to active-high (VDD) for normal operation and exhibit high-impedance inputs - no pull-up resistors are required unless open-drain control is used.
Can TLV2624ID drive capacitive loads without instability?
TLV2624ID is stable for capacitive loads ≤10 pF with a 2-kΩ series resistor in the feedback path. For larger loads (e.g., ADC input capacitance), external isolation - such as a 10-Ω resistor between TLV2624ID output and the load - is required. Phase margin drops from 63° at 10 pF to <45° at 100 pF without compensation, risking ringing or oscillation in closed-loop configurations.
What is the typical input offset voltage specification for TLV2624ID?
The typical input offset voltage for TLV2624ID is 250 µV at 25°C, with a maximum of 3500 µV across the full -40°C to 125°C industrial temperature range. This value is measured with VIC = VDD/2 and VO = VDD/2, and includes contributions from both input offset voltage and its 3 µV/°C temperature coefficient - critical for DC-coupled precision applications like strain gauge amplification.
