Product details
Overview
TLV2624IN 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, featuring 11 MHz gain-bandwidth, 10 V/µs slew rate, 800 µA per channel supply current, and shutdown capability (4 µA/channel in SHDN mode). It targets high-resolution data acquisition systems interfacing with ADCs/DACs in battery-powered industrial sensors.
For engineers reviewing the TLV2624IN datasheet, TLV2624IN pinout, TLV2624IN application, or TLV2624IN 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), low 27 nV/√Hz input voltage noise at 1 kHz, and guaranteed operation across –40°C to 125°C.
Technical Context
The TLV2624IN implements a CMOS input stage enabling ultralow input bias current (2 pA typ) and rail-to-rail output swing using complementary push-pull output transistors. Its internal architecture supports stable unity-gain operation with 63° phase margin into 2 kΩ//10 pF loads.
It integrates independent shutdown control per amplifier pair: Pin 8 (1/2SHDN) disables channels 1 and 2; Pin 9 (3/4SHDN) disables channels 3 and 4. Input common-mode range extends to the positive rail, enabling direct interface with VDD-referenced signal sources without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 11 MHz - enables stable closed-loop operation up to ~10× gain at 1 MHz for anti-aliasing or sensor signal conditioning |
| Slew rate | 10 V/µs - supports full-scale step response of 10-Vpp signals within 1 µs for fast-settling data converter drivers |
| Supply current per channel | 800 µA - allows four amplifiers to operate from a single 3.3-V Li-ion cell while maintaining bandwidth |
| Input voltage noise | 27 nV/√Hz at 1 kHz - preserves SNR in precision 16-bit+ ADC front-ends with <10-kHz signal bandwidth |
| Shutdown current per channel | 4 µA - reduces total system quiescent power by >99% when amplifiers are idle in intermittent-sampling applications |
| Common-mode input range | 1 V to VDD + 0.2 V - accepts inputs tied directly to VDD (e.g., resistive divider outputs) without clipping |
| Operating temperature | –40°C to 125°C - qualified for under-hood automotive sensors and industrial motor control feedback loops |
Pinout & Package
TLV2624IN is packaged in a 14-pin plastic DIP (PDIP) with 0.300-inch body width, through-hole mounting, and RoHS-compliant lead finish (CU NIPDAU). The package supports manual soldering and wave soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier 1 output - drives loads up to ±40 mA with rail-to-rail swing (0.2 V from rails at 10 mA) |
| 2 | 1IN− | Inverting input of Amp 1 - high-impedance CMOS node (100 GΩ typical) for precision feedback networks |
| 3 | 1IN+ | Non-inverting input of Amp 1 - accepts common-mode voltages up to VDD + 0.2 V |
| 4 | VDD | Positive supply - must be decoupled with ≥0.1 µF ceramic capacitor near pin for stability |
| 5 | 2IN+ | Non-inverting input of Amp 2 - electrically isolated from other inputs; shares no internal nodes |
| 6 | 2IN− | Inverting input of Amp 2 - matched offset and bias performance to Amp 1 per datasheet characterization |
| 7 | 2OUT | Amplifier 2 output - independently buffered; crosstalk to other channels < –100 dB at 10 kHz |
| 8 | 1/2SHDN | Shutdown control for Amps 1 & 2 - logic-low (<0.4 V) disables both; high-Z state not allowed |
| 9 | 3/4SHDN | Shutdown control for Amps 3 & 4 - independent of Pin 8; enables selective channel power gating |
| 10 | 3OUT | Amplifier 3 output - identical AC/DC specs to Amps 1 & 2; validated over full temperature range |
| 11 | 3IN− | Inverting input of Amp 3 - input capacitance 8 pF typical; critical for high-frequency stability compensation |
| 12 | 3IN+ | Non-inverting input of Amp 3 - same VICR and bias specs as Pins 2/3/5/6/11/13 |
| 13 | 4IN+ | Non-inverting input of Amp 4 - supports DC-coupled sensor interfaces requiring rail-inclusive common-mode range |
| 14 | GND | Analog ground reference - must connect to low-impedance system ground plane; separate from digital ground if mixed-signal |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2624IDR | Same electrical specs; SOIC-14 package (surface-mount, 3.9-mm width) vs PDIP-14 (through-hole, 7.62-mm width) | Requires PCB redesign for SMT assembly; better thermal performance (θJA = 122.3°C/W vs 176°C/W) and higher density | Select TLV2624IDR for automated production; TLV2624IN for prototyping, through-hole legacy designs, or high-vibration environments |
| OPA4340UA | Lower 5.5-MHz GBW, higher 750-µA/channel supply current, no shutdown function, wider 2.7–36-V supply range | Lacks power-gating capability; suited for wide-supply industrial controls but not battery-constrained portable devices | Choose OPA4340UA only when extended supply range (>5.5 V) or higher output drive (>20 mA) is required; TLV2624IN preferred for low-power, shutdown-enabled designs |
Compared with TLV2624IDR, TLV2624IN offers mechanical robustness and hand-solderability at the cost of larger footprint and higher thermal resistance; versus OPA4340UA, TLV2624IN delivers superior bandwidth-per-mA and integrated shutdown-critical for energy-sensitive medical and portable instrumentation.

FAQ
What is the maximum recommended supply voltage for TLV2624IN?
The absolute maximum supply voltage for TLV2624IN 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 the device's qualified specifications. At 5.5 V, all parameters-including 11-MHz gain-bandwidth and 10 V/µs slew rate-remain fully guaranteed across –40°C to 125°C.
Does TLV2624IN support true rail-to-rail input operation?
TLV2624IN features rail-to-rail *output* swing but not rail-to-rail *input*. Its common-mode input voltage range is specified from 1 V to VDD + 0.2 V, meaning it accepts inputs down to 1 V above ground-not down to GND. This allows direct interface with VDD-referenced sources but requires level-shifting for sub-1-V signals.
How does the shutdown function work on TLV2624IN?
TLV2624IN uses two dedicated shutdown pins: Pin 8 (1/2SHDN) disables amplifiers 1 and 2; Pin 9 (3/4SHDN) disables amplifiers 3 and 4. Driving either pin to ≤0.4 V places its associated pair in ultralow-current shutdown (4 µA/channel). Both pins must be ≥2 V to enable all four amplifiers. No internal pull-ups exist-external logic or microcontroller GPIO must drive them.
Can TLV2624IN drive capacitive loads without oscillation?
TLV2624IN 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), a 10- to 100-Ω isolation resistor between TLV2624IN output and the load is required to maintain ≥63° phase margin. The datasheet confirms stability with CL = 10 pF and RL = 2 kΩ, but not beyond without external compensation.
What is the input offset voltage specification for TLV2624IN over temperature?
TLV2624IN has a maximum input offset voltage of 4500 µV over the full –40°C to 125°C range, with a typical value of 250 µV at 25°C. Its offset voltage drift is 3 µV/°C (typ), resulting in worst-case drift of ~500 µV across the full temperature span. This performance is sufficient for 12-bit precision applications but may require calibration for 16-bit systems.
