Product details
Overview
TLV2472AIP from Texas Instruments is a dual-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-power, high-output-drive applications. It delivers 2.8MHz gain-bandwidth, ±35mA output drive at 500mV from rails, 600μA/channel supply current, and 250μV typical input offset voltage across 2.7V–6V supply range - enabling precision signal conditioning in battery-powered sensor interfaces and portable medical devices.
For engineers reviewing the TLV2472AIP datasheet, TLV2472AIP pinout, TLV2472AIP application, or TLV2472AIP equivalent, this page provides verified technical context, package-validated pin functions, real-world application mappings, and two confirmed alternative parts with documented functional trade-offs for design-in decisions.
Technical Context
The TLV2472AIP implements a CMOS input stage with rail-to-rail common-mode input range (0V to VDD) and rail-to-rail output swing (within 180mV of rails at ±10mA), supporting single-supply operation down to 2.7V. Its 2.8MHz unity-gain bandwidth and 1.5V/μs slew rate enable stable closed-loop performance in unity-gain buffers and active filters.
It features no internal shutdown control - unlike TLV2470/2473/2475 variants - as confirmed by absence of SHDN pin in its MSOP-8 pinout and omission from all shutdown-related electrical specs (IDD(SHDN)) in the datasheet. Thermal performance is characterized via θJA = 122.3°C/W (SOIC-8) and θJC = 26.9°C/W, with full specification over –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - supports direct Li-ion (3.7V nominal) and dual-cell alkaline (3V) systems without regulation. |
| Gain-Bandwidth Product | 2.8MHz - enables stable unity-gain buffer operation up to ~2.5MHz with 10kΩ load and 100pF capacitance. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 100Ω loads directly (e.g., ADC reference buffers, DAC output stages). |
| Input Offset Voltage | 250μV (typ) - ensures <0.01% error in 2.5V full-scale instrumentation amplifiers. |
| Input Bias Current | 2.5pA (typ) - preserves high-impedance sensor node accuracy (e.g., pH electrodes, piezoresistive bridges). |
| Supply Current per Channel | 600μA (typ at 5V) - enables dual-opamp signal chains consuming <1.3mW total at 5V. |
| Common-Mode Input Range | 0V to VDD - allows direct interfacing with unipolar sensors (e.g., 0–3.3V thermistor dividers) without level-shifting. |
Pinout & Package
TLV2472AIP is housed in an 8-pin MSOP (DGN) package with exposed thermal pad, measuring 3.0mm × 3.0mm × 1.0mm. Pin 1 is marked by a beveled edge or molded dot; pin numbering follows standard MSOP top-view counterclockwise convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers rail-to-rail output swing; requires no external pull-up/down for high-Z shutdown (no internal SHDN). |
| 2 (IN− A) | Channel A inverting input | High-impedance CMOS node; sensitive to PCB leakage - guard ring recommended for <1pA bias-critical designs. |
| 3 (IN+ A) | Channel A noninverting input | Accepts signals from 0V to VDD; enables single-supply transducer interface without level shifters. |
| 4 (GND) | Analog ground reference | Must connect to low-impedance system ground plane; shares return path with VDD decoupling capacitor. |
| 5 (IN+ B) | Channel B noninverting input | Independent of Channel A; supports differential pair configurations or separate signal paths. |
| 6 (IN− B) | Channel B inverting input | Matched to IN− A for common-mode rejection; layout symmetry critical for >80dB CMRR. |
| 7 (OUT B) | Channel B output | Electrically identical to OUT A; supports independent loading up to ±35mA each. |
| 8 (VDD) | Positive supply rail | Requires 100nF ceramic decoupling within 5mm; accepts 2.7–6V with monotonic operation across full range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3.3V systems - e.g., 0–3.3V ADC input scaling without headroom loss. |
| 600μA/channel quiescent current | Permits always-on dual-opamp front-ends in portable ECG monitors with <2.6mW total power at 3.3V. |
| ±35mA output drive | Eliminates need for external buffer transistors when driving 10-bit SAR ADC reference inputs (e.g., AD7476). |
| 2.5pA input bias current | Maintains <0.5mV error in 1GΩ photodiode TIA configurations - critical for low-light optical sensing. |
| 2.8MHz GBW with unity-gain stability | Supports anti-aliasing filter design up to 1.2MHz cutoff while preserving phase margin >60° with 100pF load. |
Applications
| Portable Medical Sensors | Industrial Process Monitoring |
|---|---|

| Automotive Cabin Air Quality | IoT Environmental Sensing |
|

IC Role / Device Role / Timing Role: Transimpedance amplifier for photodetector current, followed by low-pass filtering stage. Use Value: 2.5pA bias current ensures <10ppm measurement error in 4000ppm CO₂ range; 2.8MHz GBW supports 10Hz modulation frequency with 60dB SNR. |
Use Scenario: Battery-operated air quality node integrating PM2.5, VOC, and temperature sensors. IC Role / Device Role / Timing Role: Multi-sensor analog multiplexer driver and anti-aliasing filter before 12-bit MCU ADC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail opamp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2472CDR | Same die, C-temp (0°C to +70°C) grade; identical electrical specs but lower max operating temperature. | Not qualified for automotive or industrial ambient environments exceeding +70°C. | Select TLV2472CDR only for cost-sensitive consumer electronics where extended temperature range is unnecessary. |
| OPA2333AIDR | Zero-drift architecture; 0.02μV/°C offset drift vs. TLV2472AIP's 0.4μV/°C; 17μV max VIO vs. 250μV typ; 17μA/ch supply current. | Superior DC precision for long-term sensor calibration; higher power consumption limits battery life in always-on nodes. | Choose OPA2333AIDR when offset drift dominates error budget (e.g., precision weigh scales); accept 28× higher IDD for 100× lower αVIO. |
Compared with TLV2472AIP, TLV2472CDR offers identical AC performance at lower cost but sacrifices industrial temperature qualification, while OPA2333AIDR trades 28× higher supply current for 100× lower offset drift - making TLV2472AIP optimal for power-constrained, moderate-precision dual-opamp signal chains.

FAQ
Does TLV2472AIP include a shutdown pin?
No, TLV2472AIP does not feature a shutdown function. Unlike TLV2470/2473/2475 variants, it lacks a dedicated SHDN terminal - confirmed by its 8-pin MSOP pinout (no pin assigned to shutdown) and absence of IDD(SHDN) specifications in the datasheet. Power must be cycled externally to disable the device.
What is the maximum capacitive load TLV2472AIP can drive without instability?
TLV2472AIP remains stable with ≤10pF capacitive load directly on the output. For larger loads (e.g., ADC input capacitance >10pF), a series null resistor (RNULL ≥20Ω) between the opamp output and load is required to maintain >60° phase margin, as specified in Figure 42 of the datasheet.
Is TLV2472AIP pin-compatible with TLV2472CDR?
Yes, TLV2472AIP and TLV2472CDR share identical MSOP-8 (DGN) packaging and pinout - both use the same 1–8 pin mapping for OUT A, IN− A, IN+ A, GND, IN+ B, IN− B, OUT B, and VDD. Only temperature grade and screening differ (I-suffix vs. C-suffix).
Can TLV2472AIP operate from a 2.5V supply?
No, TLV2472AIP has a minimum supply voltage of 2.7V per Absolute Maximum Ratings and Recommended Operating Conditions tables. Operation below 2.7V is not characterized and may result in degraded parameters including reduced output swing, increased VIO, and instability.
What is the thermal resistance (θJA) of TLV2472AIP in MSOP-8 package?
The TLV2472AIP in MSOP-8 (DGN) package has θJA = 52.7°C/W and θJC = 4.7°C/W, as listed in the Dissipation Rating Table. These values assume JEDEC-standard PCB layout with 1-inch² 2oz copper pad under the exposed thermal pad.
