Product details
Overview
TLV2623IN from Texas Instruments is a dual-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, 27 nV/√Hz input voltage noise, 800 µA per channel supply current, and shutdown capability with 4 µA/channel quiescent current. It operates across –40°C to +125°C and targets high-resolution data acquisition and portable instrumentation.
For engineers reviewing the TLV2623IN datasheet, TLV2623IN pinout, TLV2623IN application, or TLV2623IN equivalent, this page delivers verified electrical specifications, MSOP-10 package layout, industrial-grade temperature performance, rail-to-rail output swing with positive-rail-inclusive input range, and direct alternatives for low-power precision signal conditioning designs.
Technical Context
The TLV2623IN implements a CMOS input stage enabling rail-to-rail output swing and common-mode input voltage range extending to VDD + 0.2 V - critical for interfacing with positive-referenced sensors and ADC drivers. Its 11 MHz unity-gain bandwidth and 10 V/µs slew rate support stable operation in unity-gain buffer and active filter configurations up to ~1 MHz with minimal phase margin degradation.
Integrated shutdown control (pin 5) reduces total supply current to 4 µA per channel while maintaining fast enable/disable timing (ton = 4.5 µs at VDD = 2.7 V; toff = 200 ns), making it suitable for duty-cycled sensor front-ends and battery-powered measurement systems requiring dynamic power management.
Key Specifications

Pinout & Package
TLV2623IN is packaged in a 10-pin VSSOP (DGS) with 0.5-mm pitch, 3.0-mm × 3.0-mm body, and exposed thermal pad (not electrically connected). This thermally enhanced, space-efficient package supports high-density PCB layouts and improves power dissipation in ambient temperatures up to +125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left floating or grounded per layout best practices. |
| 2 | IN− (Ch1) | Inverting input of Channel 1 - high-impedance CMOS node (2 pA bias current) for precision feedback networks. |
| 3 | IN+ (Ch1) | Non-inverting input of Channel 1 - accepts signals up to VDD + 0.2 V, enabling rail-to-rail sensor interfacing. |
| 4 | GND | Analog ground reference - requires low-impedance connection to PCB ground plane to minimize noise coupling. |
| 5 | SHDN | Active-low shutdown control - pulls below 0.4 V to disable both amplifiers; open or tied to VDD for normal operation. |
| 6 | VDD | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 2 mm of pin for stability. |
| 7 | OUT (Ch1) | Channel 1 output - rail-to-rail swing (within 100 mV of rails at 10 mA load) for full dynamic range utilization. |
| 8 | OUT (Ch2) | Channel 2 output - independently buffered; crosstalk < –100 dB at 10 kHz ensures isolated dual-channel operation. |
| 9 | IN+ (Ch2) | Non-inverting input of Channel 2 - identical VICR and bias specs as Pin 3 for matched dual-path design. |
| 10 | IN− (Ch2) | Inverting input of Channel 2 - symmetrical layout with Pin 2 enables matched trace routing in differential front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power, rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2622IDGK | Same family, 8-pin VSSOP (DGK), no shutdown pin; 800 µA/channel, 11 MHz GBW, same VICR and noise. | Lacks shutdown control - unsuitable for power-gated systems but simpler for always-on signal chains. | Select TLV2622IDGK when board space is constrained and continuous operation is acceptable; TLV2623IN preferred when dynamic power management is required. |
| OPA2333AIDGSR | Zero-drift architecture, 0.02 µV/°C offset drift, 60 µV max VIO, 350 kHz GBW, 175 µA/channel, no shutdown. | Superior DC accuracy and lower power, but insufficient bandwidth for >100 kHz signal paths. | Choose OPA2333AIDGSR for precision DC-coupled applications like weigh scales; TLV2623IN remains optimal for AC-coupled, wideband sensor buffering where speed/noise trade-off favors 11 MHz. |
Compared with TLV2622IDGK, TLV2623IN adds shutdown functionality at identical speed and noise, enabling >99% power reduction in idle states; versus OPA2333AIDGSR, TLV2623IN trades zero-drift DC precision for 31× higher bandwidth and 4.6× higher slew rate - essential for time-domain fidelity in dynamic measurements.

FAQ
What is the maximum load capacitance TLV2623IN can drive while maintaining stability?
The TLV2623IN maintains ≥63° phase margin with RL = 2 kΩ and CL = 10 pF at 25°C. Driving capacitive loads >100 pF requires series output resistance (typically 10–50 Ω) to isolate the amplifier from the load and prevent peaking or oscillation - confirmed by Figure 16 in the datasheet showing phase margin degradation beyond 300 pF with Rnull = 0 Ω.
Does TLV2623IN support split-supply operation?
Yes, TLV2623IN supports split supplies within ±1.35 V to ±2.75 V (±VDD limits), as specified in the Recommended Operating Conditions table. However, its rail-to-rail output and positive-rail-inclusive input are optimized for single-supply use; split-supply operation is valid but does not unlock additional features beyond standard op-amp behavior.
What is the typical input offset voltage drift over temperature for TLV2623IN?
The TLV2623IN exhibits a typical input offset voltage drift (αVIO) of 3 µV/°C, measured across the full –40°C to +125°C range. This low drift, combined with a maximum VIO of 3500 µV at 25°C and 4500 µV over temperature, ensures stable DC gain accuracy in closed-loop sensor interfaces without frequent recalibration.
Can TLV2623IN drive a 2-kΩ load to rail with 10-mA output current?
Yes - at VDD = 5 V, TLV2623IN delivers VOH ≥ 4.7 V and VOL ≤ 0.25 V into 10 mA loads (per Electrical Characteristics Table), achieving rail-to-rail swing within 300 mV. At VDD = 2.7 V, output swing is within 150 mV of rails at 10 mA, meeting rail-to-rail specification for both supply extremes.
Is the NC pin (Pin 1) on TLV2623IN electrically connected internally?
No - Pin 1 of TLV2623IN is explicitly designated "NC" (No internal connection) in the official TI pinout diagram and datasheet. It must remain unconnected on the PCB; grounding or routing to any net may compromise thermal performance or introduce parasitic coupling due to proximity to the exposed thermal pad.
