Product details
Overview
TLV2623IDR from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier with shutdown control, designed for low-power, wide-bandwidth signal conditioning in single-supply systems. It delivers 11 MHz gain-bandwidth, 10 V/µs slew rate, 27 nV/√Hz input voltage noise, 800 µA/channel supply current, and operates from 2.7 V to 5.5 V across –40°C to 125°C - enabling use in Li-ion powered data acquisition front-ends.
For engineers reviewing the TLV2623IDR datasheet, TLV2623IDR pinout, TLV2623IDR application, or TLV2623IDR 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), ultralow 4 µA/channel shutdown current, and MSOP-10 packaging optimized for space-constrained industrial sensing and portable instrumentation.
Technical Context
The TLV2623IDR implements a CMOS input stage with rail-to-rail output stage, supporting operation down to 2.7 V while maintaining full differential voltage amplification (90–100 dB) and phase margin (63°) at 11 MHz. Its input common-mode range extends to the positive supply rail, enabling direct interfacing with high-side referenced sensors and ADC reference buffers.
Shutdown functionality is controlled via dedicated SHDN pins (pins 5 and 8), each independently disabling one amplifier channel with 200 ns turnoff time and 1.5–4.5 µs turnon time. The device uses internal biasing that ensures stable DC performance over temperature (±3 µV/°C offset drift) and supply voltage variation (75–99 dB PSRR).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 11 MHz - supports stable unity-gain buffer configurations up to 11 MHz without external compensation. |
| Slew rate | 10 V/µs - enables accurate reproduction of fast 10-Vpp signals up to ~1.6 MHz without slew-induced distortion. |
| Input voltage noise | 27 nV/√Hz at 10 kHz - suitable for precision sensor amplification where low-frequency noise dominates dynamic range. |
| Supply current per channel | 800 µA at 2.7–5 V - allows dual op-amp operation within 1.6 mA total, critical for battery-powered 12-bit+ SAR ADC drivers. |
| Shutdown current per channel | 4 µA typical - reduces system standby power by >99% versus active mode, enabling duty-cycled signal chains. |
| Common-mode input range | 1 V to VDD + 0.2 V - permits direct connection to 0–VDD-scaled transducer outputs without level-shifting circuitry. |

Pinout & Package
TLV2623IDR is housed in a 10-pin VSSOP (DGS) package measuring 3.0 mm × 3.0 mm × 1.0 mm, with exposed thermal pad for enhanced power dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused pin; must be left floating or tied to GND for mechanical stability - no electrical function. |
| 2 (IN−) | Inverting input | Differential input node for Channel 1; accepts signals up to VDD + 0.2 V with rail-to-rail common-mode support. |
| 3 (IN+) | Non-inverting input | Channel 1 input with same common-mode range as IN−; enables high-side referenced sensor interface. |
| 4 (GND) | Analog ground | Primary return path for both channels; requires low-impedance PCB connection to minimize noise coupling. |
| 5 (SHDN) | Channel 1 shutdown control | Active-low logic input; <0.4 V disables Channel 1, reducing its IDD to 4 µA; >2 V enables operation. |
| 6 (VDD) | Positive supply | Single 2.7–5.5 V rail powering both amplifiers and shutdown logic; bypass capacitor required at pin. |
| 7 (OUT) | Channel 1 output | Rail-to-rail output capable of sourcing/sinking ±28 mA; drives 2-kΩ loads to within 260 mV of rails at 5 V. |
| 8 (SHDN) | Channel 2 shutdown control | Independent active-low enable for Channel 2; allows asymmetric power management in multi-stage filters. |
| 9 (OUT) | Channel 2 output | Second rail-to-rail output with identical drive strength and load regulation as Pin 7. |
| 10 (NC) | No internal connection | Unused pin; electrically isolated - no routing or termination required beyond mechanical mounting. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives loads to within 260 mV of VDD/GND at 5 V, preserving dynamic range in 12-bit+ data converter interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2622IDR | Same family, 8-pin SOIC package; lacks Channel 2 SHDN pin and second NC pin - only one shared shutdown control for both channels. | Not suitable for asymmetric power management; limited PCB layout flexibility due to larger SOIC footprint (4.9 mm × 3.9 mm vs DGS 3.0 mm × 3.0 mm). | Select TLV2622IDR only if board space is unconstrained and independent channel shutdown is unnecessary. |
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C offset drift); lower input offset (2 µV max) but reduced GBW (350 kHz) and higher supply current (17 µA/ch). | Better for DC-precision applications (e.g., weigh scales); unsuitable for >100 kHz signal paths due to bandwidth limitation. | Choose OPA2333AIDR when ultra-low offset drift dominates over speed and power; avoid for high-frequency sensor interfaces. |
Compared with TLV2622IDR, TLV2623IDR provides independent shutdown control and smaller MSOP-10 packaging for space-sensitive designs; compared with OPA2333AIDR, it trades DC precision for 31× higher bandwidth and 21× lower quiescent current - making TLV2623IDR optimal for battery-powered, medium-speed analog signal chains.

FAQ
What is the maximum recommended supply voltage for TLV2623IDR?
The absolute maximum supply voltage for TLV2623IDR is 6 V, but the recommended operating range is 2.7 V to 5.5 V. Operating above 5.5 V risks permanent damage, while operation below 2.7 V may cause degraded AC performance including reduced slew rate and bandwidth. TI specifies all electrical characteristics within the 2.7–5.5 V window, and the device is optimized for lithium-ion cell voltages (3.0–4.2 V nominal).
Does TLV2623IDR support true rail-to-rail input operation?
TLV2623IDR does not support rail-to-rail *input* - its common-mode input voltage range is specified from 1 V to VDD + 0.2 V. This means the input cannot go below 1 V (i.e., not to GND), but it *does* include the positive supply rail. This architecture enables direct interfacing with high-side referenced sources while avoiding input stage saturation near ground - a deliberate trade-off for speed and noise performance in the TLV262x family.
How is shutdown controlled on TLV2623IDR, and what happens to the output during shutdown?
TLV2623IDR features two independent active-low shutdown pins: Pin 5 controls Channel 1, and Pin 8 controls Channel 2. When a shutdown pin is pulled ≤0.4 V, its respective amplifier enters ultralow-power mode (IDD(SHDN) = 4 µA/channel), and its output becomes high-impedance - not clamped or shorted. This allows safe multiplexing or cascaded topologies without loading downstream stages. Turnoff time is 200 ns; turnon time is 1.5–4.5 µs depending on supply voltage.
What is the thermal performance of TLV2623IDR in the DGS package?
In its 10-pin VSSOP (DGS) package, TLV2623IDR has a junction-to-ambient thermal resistance (θJA) of 259.7°C/W and junction-to-case (θJC) of 54.1°C/W. At maximum ambient temperature (125°C) and full 5.5 V operation, the device dissipates up to 97 mW - limiting continuous output current to ~10 mA per channel into typical loads. For sustained high-current operation, PCB copper area under the thermal pad and airflow should be optimized per TI's SLMA002 guidelines.
Can TLV2623IDR drive capacitive loads, and what is the maximum stable capacitance?
TLV2623IDR is characterized for stability with 10 pF load capacitance (CL) and 2-kΩ resistive load, achieving 63° phase margin. Driving larger capacitive loads (>50 pF) without isolation resistance risks peaking or oscillation. TI recommends adding a 10–100 Ω series resistor between the output and capacitive load to maintain stability - especially when driving ADC input capacitors or long PCB traces. No internal compensation is provided for heavy capacitive loading.
