Product details
Overview
TLV2622ID from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for low-power, wide-bandwidth single-supply operation. It delivers 11 MHz gain-bandwidth, 10 V/µs slew rate, and 800 µA/channel supply current across 2.7 V to 5.5 V supply range, with input common-mode range extending to the positive rail. It is used in high-resolution data acquisition front-ends interfacing with SAR ADCs in battery-powered industrial sensors.
For engineers reviewing the TLV2622ID datasheet, TLV2622ID pinout, TLV2622ID application, or TLV2622ID equivalent, key selection criteria include its 2.7-V minimum supply compatibility with Li-ion cells, ultralow 4 µA/channel shutdown current, and guaranteed −40°C to +125°C industrial temperature operation without derating.
Technical Context
The TLV2622ID implements a CMOS input stage with rail-to-rail output swing and a common-mode input voltage range from 1 V to VDD + 0.2 V. Its internal architecture supports stable unity-gain operation with 63° phase margin into 2 kΩ//10 pF loads at both 2.7 V and 5 V supplies.
It integrates independent shutdown control per channel via dedicated SHDN pins (Pin 1 and Pin 8 in SOIC-8), enabling dynamic power management in multi-stage signal chains. The device maintains 27 nV/√Hz input voltage noise and <0.095% THD+N at 10 kHz, making it suitable for precision analog signal conditioning prior to high-speed data conversion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - Enables direct operation from single Li-ion cell (3.0–3.7 V nominal) or regulated 3.3 V/5 V rails. |
| Gain-Bandwidth Product | 11 MHz - Supports closed-loop bandwidths up to ~10 MHz in unity-gain buffer configurations for anti-aliasing or driver stages. |
| Slew Rate | 10 V/µs - Sustains full-scale 1 Vpp output transitions at ≥1 MHz without slewing distortion in 12-bit+ systems. |
| Supply Current per Channel | 800 µA - Delivers high-speed performance at sub-mA quiescent current, critical for always-on sensor nodes. |
| Input Noise Voltage | 27 nV/√Hz @ 10 kHz - Low enough to avoid degrading SNR of 16-bit SAR ADCs with ≥100 kSPS sampling rates. |
| Shutdown Current per Channel | 4 µA - Reduces total system standby power by >99% versus active mode, enabling microamp-level sleep states. |
| Operating Temperature | −40°C to +125°C - Qualified for under-hood automotive, motor drive feedback, and industrial PLC I/O modules. |
Pinout & Package
TLV2622ID is packaged in an 8-pin SOIC (D package), 3.9 mm × 4.9 mm body, with standard JEDEC MS-012AC outline and RoHS-compliant NiPdAu lead finish. Tube packaging contains 75 units per tube.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Shutdown | Active-low logic input; pulls channel 1 output to high-impedance state when ≤0.4 V, reducing IDD to 4 µA. |
| 2 | Channel 1 Inverting Input | Differential input node for first op-amp; accepts signals up to VDD + 0.2 V due to CMOS input stage. |
| 3 | Channel 1 Non-Inverting Input | Reference or signal input for non-inverting configurations; shares same VICR as Pin 2 (1 V to VDD + 0.2 V). |
| 4 | Ground | Analog and digital ground reference; must be low-impedance return path for both channels and shutdown logic. |
| 5 | Channel 2 Non-Inverting Input | Independent input for second op-amp; enables dual-path signal conditioning (e.g., signal + reference buffer). |
| 6 | Channel 2 Inverting Input | Second differential input; supports independent gain-setting networks without crosstalk coupling. |
| 7 | Channel 2 Output | Rail-to-rail output capable of sourcing/sinking ±28 mA; drives 2 kΩ loads to within 200 mV of rails at 5 V. |
| 8 | Positive Supply / Channel 2 Shutdown | VDD connection and shared shutdown control for channel 2; Pin 8 functions as VDD, not SHDN - confirmed by TLV2622 pinout diagram and D-package labeling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives loads to within 200 mV of VDD/GND at 5 V and 10 mA, preserving dynamic range in 3.3 V systems. |
| Input common-mode range includes VDD | Accepts inputs up to VDD + 0.2 V, enabling direct interface to VDD-referenced sensors or DAC outputs. |
| 11-MHz GBW at 800 µA/channel | Delivers bandwidth-per-power ratio >13.75 MHz/mA - 2.5× higher than comparable TLV2632 at same current. |
| Ultralow shutdown current | 4 µA/channel ensures <1 µA total system leakage in dual-channel off-state, critical for energy harvesting designs. |
| Industrial temperature grade | Specified performance over −40°C to +125°C without test limits or derating - validated for motor control feedback loops. |

Use Scenario: Signal buffering and level-shifting between field-side sensors and isolated microcontroller ADCs in modular PLC I/O cards. IC Role / Device Role / Timing Role: Dual-channel isolation barrier interface driver; one channel conditions 4–20 mA loop receiver output, the other buffers isolated reference.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2632IDR | Lower GBW (10 MHz), lower slew rate (9 V/µs), identical shutdown current (4 µA) and supply range (2.7–5.5 V). | Optimized for lower power at reduced bandwidth; suitable where <10 MHz closed-loop bandwidth suffices. | Choose TLV2632IDR if system bandwidth requirement is ≤8 MHz and THD+N <0.02% at 10 kHz is prioritized over speed. |
| OPA2333AIDR | Zero-drift architecture, 0.02 µV/°C offset drift, but lower GBW (350 kHz), higher supply current (17 µA), no shutdown. | Targeted at DC-precision applications (e.g., weigh scales); lacks shutdown and bandwidth for high-speed data paths. | Choose OPA2333AIDR only for ultra-low offset drift requirements (<1 µV max) where bandwidth <500 kHz is acceptable and shutdown is unnecessary. |
Compared with TLV2622ID, TLV2632IDR trades 1 MHz bandwidth and 1 V/µs slew rate for marginally better DC precision, while OPA2333AIDR abandons speed and power efficiency entirely to achieve nanovolt-level offset stability - making TLV2622ID the sole choice when 10+ MHz bandwidth, sub-mA current, and shutdown capability are jointly required.

FAQ
What is the maximum load capacitance TLV2622ID can drive while maintaining stability?
The TLV2622ID maintains 63° phase margin with a 2 kΩ resistive load and 10 pF capacitive load, as verified in the datasheet Figure 16. Driving >100 pF requires external isolation resistor (e.g., 10–100 Ω in series with output) to prevent peaking or oscillation - a design constraint confirmed by phase margin vs. CL characterization across 10–300 pF.
Does TLV2622ID support true rail-to-rail input operation?
No - TLV2622ID features rail-to-rail *output* swing but its input common-mode range extends from 1 V to VDD + 0.2 V, excluding the negative rail (GND). This allows interfacing with VDD-referenced sources but not ground-referenced bipolar signals without level shifting.
What is the function of Pin 8 on TLV2622ID in the SOIC-8 package?
Pin 8 is the positive supply (VDD) terminal - not a shutdown pin. The TLV2622ID uses Pin 1 for Channel 1 shutdown and has no dedicated SHDN pin for Channel 2; shutdown for Channel 2 is controlled via Pin 8 only in quad variants (TLV2624/2625), not in the dual TLV2622. This is explicitly shown in the "TLV2622 D, DGK, OR P PACKAGE" pinout diagram.
Can TLV2622ID operate from a 2.5 V supply?
No - the absolute minimum supply voltage for TLV2622ID is 2.7 V, as specified in Recommended Operating Conditions (Table 3). Operation below 2.7 V is outside datasheet specifications and may result in degraded AC performance, increased offset, or failure to meet phase margin guarantees.
Is TLV2622ID pin-compatible with TLV2621ID or TLV2620ID?
No - TLV2622ID is an 8-pin dual op-amp in SOIC/DGK packages, whereas TLV2621ID is a 5-pin single op-amp (SOT-23) and TLV2620ID is a 6-pin single op-amp (SOT-23). They differ in channel count, pin count, pinout, and package footprint; no mechanical or electrical pin compatibility exists between these variants.
