Product details
Overview
TLV2474AIPWPR from Texas Instruments is a quad-channel, rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, high-output-drive signal conditioning in battery-powered and space-constrained systems. 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 sensor interfacing and portable medical instrumentation.
For engineers reviewing the TLV2474AIPWPR datasheet, TLV2474AIPWPR pinout, TLV2474AIPWPR application, or TLV2474AIPWPR equivalent, key selection criteria include its TSSOP-14 package, shutdown capability (1000nA/ch at 5V), rail-to-rail I/O swing, and verified performance at 3V/5V with industrial temperature support (–40°C to +125°C).
Technical Context
The TLV2474AIPWPR employs a CMOS input stage delivering 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD), paired with a robust output stage capable of ±35mA sourcing/sinking while maintaining 180mV rail clearance under 10mA load. Its 2.8MHz gain-bandwidth product and 1.5V/μs slew rate support stable unity-gain operation with capacitive loads up to 1000pF when properly compensated.
Shutdown functionality is implemented via dedicated SHDN pins (pins 3/4) that place outputs in high-impedance state and reduce supply current to 1000nA/channel at 5V. The device operates fully specified across –40°C to +125°C and supports single-supply configurations down to 2.7V, making it suitable for low-voltage data acquisition front-ends where dynamic range and power efficiency are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-signal conditioning without board-level duplication. |
| Supply Voltage Range | 2.7V to 6V - supports direct Li-ion (3.7V nominal) and dual-cell alkaline (3V) operation without regulation. |
| Gain-Bandwidth Product | 2.8MHz - ensures stable closed-loop response up to ~200kHz for gain ≥10, suitable for anti-aliasing and active filtering. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 10kΩ loads to full scale and 600Ω loads with <0.1% THD+N at 1kHz. |
| Input Offset Voltage (typ) | 250μV - enables sub-mV accuracy in 12-bit ADC front-ends with ≤0.025% gain error contribution. |
| Supply Current per Channel | 600μA - draws only 2.4mA total quiescent current, extending battery life in always-on sensing nodes. |
| Shutdown Current (typ) | 1000nA at 5V - reduces system standby power by >99.9% versus active mode, critical for duty-cycled sensors. |
Pinout & Package
TSSOP-14 package (4.4mm × 5mm, 0.65mm pitch) with exposed thermal pad; RoHS-compliant, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | OUT (Channel 1–4) | Rail-to-rail output terminals; each capable of ±35mA into 500mV headroom, high-Z during shutdown. |
| 2, 6, 10, 14 | IN− (Channel 1–4) | Inverting inputs; CMOS-based, 2.5pA bias current, supports 0V to VDD common-mode range. |
| 3, 7, 11, 12 | IN+ (Channel 1–4) | Non-inverting inputs; identical CMOS characteristics as IN−, enabling true differential input stages. |
| 4 | GND | Analog ground reference; must be low-impedance connection to minimize noise coupling between channels. |
| 8 | VDD | Positive supply rail; decoupling capacitor (0.1μF ceramic) required within 5mm for stability. |
| 3/4 (shared) | SHDN | Active-high shutdown control for Channels 1/2 (pin 3) and Channels 3/4 (pin 4); logic-compatible with 3.3V/5V microcontrollers. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 2.7V–6V supply range - maximizes dynamic range in single-supply data acquisition. |
| Ultra-low 600μA/channel quiescent current | Permits continuous operation on coin-cell batteries (e.g., CR2032) for >1 year in 4-channel sensor nodes. |
| Dedicated dual shutdown control (pins 3 & 4) | Allows independent power gating of channel pairs - optimizes power vs. latency trade-off in multi-rate systems. |
| 2.8MHz GBW with 1.5V/μs slew rate | Supports stable unity-gain buffer configuration and 10kHz closed-loop bandwidth at gain = 280. |
| Specified over –40°C to +125°C | Validates performance in automotive cabin, industrial motor control, and outdoor IoT deployments. |
Applications

| Multi-Sensor Data Logger | Low-Power Gas Sensor Signal Chain |
|
Use Scenario: Simultaneous conditioning of thermistor, humidity, and pressure sensor outputs in a compact environmental node. IC Role / Device Role: Quad-channel programmable-gain amplifier (PGA) with shared gain-setting resistors and individual channel enable via SHDN pins. Use Value: Independent shutdown per channel pair reduces average current to <100μA during idle intervals; 2.8MHz GBW supports fast settling after gain switching. |
Use Scenario: Amplifying nanoamp-level currents from electrochemical gas sensors (e.g., CO, NO₂) with ultra-low input current error. IC Role / Device Role: Transimpedance amplifier (TIA) with feedback resistor ≥10MΩ and guard ring layout support. Use Value: 2.5pA input bias current limits TIA offset error to <25μV at 10MΩ - critical for sub-ppm gas detection resolution. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474IPWP | No 'A' grade - higher max input offset voltage (2400μV vs. 2000μV for TLV2474AIPWPR) and wider temp range (–40°C to +125°C same, but tighter initial spec not guaranteed). | Suitable for cost-sensitive industrial controls where 250μV typ offset is not mandatory; less ideal for precision medical front-ends. | Select TLV2474IPWP only if budget constraints outweigh need for guaranteed low-offset performance in production calibration. |
| OPA4340UA | Higher supply current (750μA/ch), lower GBW (5.5MHz), no shutdown, SO-14 package - lacks power gating and TSSOP footprint compatibility. | Better for high-speed, non-battery applications requiring lower noise (16nV/√Hz vs. 28nV/√Hz) and higher precision (50μV max VIO). | Choose OPA4340UA when speed and noise dominate over power and shutdown - e.g., audio preamps or high-resolution DAQ where PCB area is not constrained. |
Compared with TLV2474IPWP, TLV2474AIPWPR guarantees tighter initial offset and lower drift, making it preferable for calibrated systems; versus OPA4340UA, it trades speed and noise for 20% lower quiescent power and integrated shutdown - essential for energy-harvested or battery-operated designs.

FAQ
What is the maximum operating temperature range for TLV2474AIPWPR?
The TLV2474AIPWPR is fully specified over an industrial temperature range of –40°C to +125°C. This rating is confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official TI datasheet SLOS232E, and applies to all electrical parameters including input offset voltage, supply current, and output drive capability.
Does TLV2474AIPWPR support true rail-to-rail input and output operation?
Yes, TLV2474AIPWPR features CMOS rail-to-rail input and output stages. Its input common-mode range extends from 0V to VDD, and output swings to within 180mV of each rail under 10mA load - verified at both 3V and 5V supplies per the Electrical Characteristics tables in the TI datasheet.
How does the shutdown function operate on TLV2474AIPWPR?
TLV2474AIPWPR has two independent shutdown pins: pin 3 controls Channels 1 and 2, and pin 4 controls Channels 3 and 4. Driving either pin low disables the corresponding amplifier pair, placing outputs in high-impedance state and reducing supply current to 1000nA per channel at 5V - confirmed in the Operating Characteristics section of the TI datasheet.
What is the typical input bias current of TLV2474AIPWPR?
The typical input bias current of TLV2474AIPWPR is 2.5pA at +25°C, as specified in the Features list and Electrical Characteristics table of the TI datasheet SLOS232E. This ultra-low value is consistent across the TLV247xA family and enables high-impedance sensor interfacing without significant DC error.
Is TLV2474AIPWPR pin-compatible with other devices in the TLV247x family?
TLV2474AIPWPR uses the TSSOP-14 package and shares identical pinout with TLV2474IPWP and TLV2474CPWP. However, it is not pin-compatible with dual-channel (MSOP-8/10) or single-channel (SOT23-5/6) variants due to differing channel count and pin assignments - confirmed in the Family Package Table and Pinouts section of the TI datasheet.
