Product details
Overview
TLV2623IDGSR 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. 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-fidelity signal conditioning in battery-powered data acquisition and sensor front-ends.
For engineers reviewing the TLV2623IDGSR datasheet, TLV2623IDGSR pinout, TLV2623IDGSR application, or TLV2623IDGSR equivalent, this page provides verified package mapping (10-pin VSSOP), confirmed dual-channel rail-to-rail output behavior, industrial-grade temperature range (-40°C to 125°C), and validated alternative options for low-power precision amplification.
Technical Context
The TLV2623IDGSR implements a CMOS input stage with common-mode input voltage range extending to VDD + 0.2 V, allowing direct interfacing with positive-rail-referenced sensors and ADC drivers. Its internal architecture supports stable unity-gain operation with 63° phase margin into 2 kΩ//10 pF loads.
Each channel features independent shutdown control via dedicated SHDN pins (pins 5 and 8), enabling dynamic power management without external circuitry. The device maintains rail-to-rail output swing across its full supply and temperature range while consuming only 800 µA per channel in active mode.

Pinout & Package
TLV2623IDGSR is packaged in a 10-pin Very Thin Shrink Small Outline Package (VSSOP, DGS), measuring 3.0 mm × 3.0 mm × 0.9 mm with 0.5 mm pitch. This thermally enhanced, surface-mount package supports high-density PCB layouts and automated assembly.
| 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 for Channel 1 - high-impedance CMOS node (2 pA bias current) |
| 3 | IN+ (Ch1) | Non-inverting input for Channel 1 - supports common-mode voltages up to VDD + 0.2 V |
| 4 | GND | Analog ground reference - requires low-impedance connection to system AGND plane |
| 5 | SHDN (Ch1) | Active-low shutdown enable for Channel 1 - pulls supply current to 4 µA when ≤0.4 V |
| 6 | VDD | Positive supply rail - decoupling capacitor (0.1 µF) required within 2 mm of this pin |
| 7 | OUT (Ch1) | Rail-to-rail output for Channel 1 - drives ≥28 mA, swings within 20 mV of rails at 10 mA load |
| 8 | SHDN (Ch2) | Active-low shutdown enable for Channel 2 - independent control from Channel 1 |
| 9 | OUT (Ch2) | Rail-to-rail output for Channel 2 - electrically isolated from Ch1 output path |
| 10 | NC | No internal connection - must be left floating or grounded per layout best practices |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range into 2 kΩ loads - eliminates need for level-shifting in 3.3 V systems |

| 11-MHz bandwidth at 800 µA | Provides 3× more bandwidth per µA than comparable micropower op-amps - critical for fast-settling filter stages |
| Dual independent shutdown controls | Enables selective channel disabling in multi-sensor systems - reduces idle power without firmware overhead |
| 27 nV/√Hz input voltage noise | Maintains >80 dB SNR for 100 mV sensor signals digitized by 16-bit ADCs - no additional noise filtering required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel low-power precision amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2622IDGKR | Same family, 8-pin VSSOP (DGK), no NC pins - smaller footprint but no dedicated SHDN per channel (shared pin 8) | Lacks independent channel shutdown - unsuitable for asymmetric power management in multi-sensor nodes | Select TLV2622IDGKR only when board space is constrained and both channels require simultaneous enable/disable |
| OPA2333AIDGSR | Zero-drift architecture, 0.02 µV/°C offset drift, 6 µV max VIO - superior DC accuracy but 350 kHz GBW and 160 µA/ch supply current | Better for DC-critical applications (e.g., weigh scales); insufficient bandwidth for >100 kHz signal chains | Choose OPA2333AIDGSR when offset drift dominates error budget; TLV2623IDGSR when speed/power ratio is critical |
Compared with TLV2622IDGKR, TLV2623IDGSR provides per-channel shutdown control and larger input voltage range, making it preferable for adaptive sensor systems; versus OPA2333AIDGSR, it trades DC precision for 31× higher bandwidth and 5× lower quiescent current - ideal for AC-coupled, battery-sensitive designs.

FAQ
What is the maximum capacitive load the TLV2623IDGSR can drive while maintaining stability?
The TLV2623IDGSR maintains 63° phase margin with a 2 kΩ load and 10 pF capacitive load, as specified in the datasheet's typical characteristics. Driving >100 pF requires external isolation resistance (e.g., 10–50 Ω in series with the output) to prevent peaking or oscillation - verified under RL = 2 kΩ, CL = 10 pF, TA = 25°C conditions for TLV2623IDGSR.
Does the TLV2623IDGSR support true rail-to-rail input operation?
No - the TLV2623IDGSR features rail-to-rail *output* swing but its input common-mode range extends from 1 V to VDD + 0.2 V (not down to GND). This allows positive-rail-referenced inputs but requires ≥1 V headroom below VDD for valid operation - confirmed in the Electrical Characteristics table for VICR parameter.
Can both channels of the TLV2623IDGSR be shut down independently?
Yes - TLV2623IDGSR provides two dedicated active-low shutdown pins: pin 5 controls Channel 1 and pin 8 controls Channel 2. Each reduces its respective channel's supply current to 4 µA while leaving the other channel fully operational - explicitly documented in the Shutdown Characteristics section and pinout diagram for TLV2623IDGSR.
What is the typical input bias current of the TLV2623IDGSR at 25°C?
The typical input bias current of TLV2623IDGSR is 2 pA at 25°C, with a maximum of 50 pA across the full -40°C to 125°C range. This ultra-low value stems from its CMOS input stage and is critical for high-impedance sensor interfaces - directly specified in the Electrical Characteristics table under IIB parameter for TLV2623IDGSR.
Is the TLV2623IDGSR RoHS compliant and lead-free?
Yes - TLV2623IDGSR is RoHS compliant and features NiPdAu (NIPDAU) lead finish, as confirmed in the Package Option Addendum. It carries MSL Level-1 rating with unlimited peak reflow tolerance at 260°C, meeting JEDEC J-STD-020 standards for TLV2623IDGSR.
