Product details
Overview
TLV2472AIPE4 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, 600μA/channel supply current, ±35mA output drive at 500mV from rails, 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 TLV2472AIPE4 datasheet, TLV2472AIPE4 pinout, TLV2472AIPE4 application, or TLV2472AIPE4 equivalent, key selection criteria include its shutdown capability (1000nA/ch at 5V), rail-to-rail swing, ultra-low input bias current (2.5pA), and MSOP-8 packaging - critical for space-constrained, low-noise, single-supply analog front-ends.
Technical Context
The TLV2472AIPE4 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 load). Its architecture supports stable operation with capacitive loads ≥10pF when using a series nulling resistor (RNULL ≥20Ω), per TI's recommended layout guidance.
It features an active-high shutdown control (SHDN pin) that places outputs in high-impedance state and reduces supply current to 1000nA/channel at 5V. The device is fully specified over –40°C to +125°C and operates down to 2.7V, making it suitable for industrial-grade portable instrumentation where power efficiency and dynamic range are co-constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2.8MHz - enables stable unity-gain buffer or closed-loop amplification up to ~200kHz with phase margin >61° into 10kΩ//1000pF. |
| Supply current per channel | 600μA at 5V - allows continuous operation in 10-year battery-powered systems drawing <1.2mA total for dual op-amp function. |
| Output drive capability | ±35mA at 500mV from rail - drives 100Ω loads directly without external buffers in data acquisition front-ends. |
| Input offset voltage | 250μV (typ) - supports 12-bit accuracy in 3V full-scale systems without trimming (LSB ≈ 730μV). |
| Rail-to-rail I/O | Inputs accept 0V to VDD; outputs swing to within 180mV of rails at ±10mA - maximizes dynamic range in 3V ADC interfaces. |
| Shutdown current | 1000nA/channel at 5V - reduces system standby power to sub-μA level while preserving fast wake-up (ton = 5μs). |
| Input bias current | 2.5pA - minimizes voltage error in high-impedance sensor nodes (e.g., pH electrodes, photodiode transimpedance). |
Pinout & Package
TLV2472AIPE4 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; the package is RoHS-compliant and rated for –40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | High-drive rail-to-rail output capable of sourcing/sinking ±35mA at 500mV from rail. |
| 2 (IN− A) | Channel A inverting input | CMOS input with 2.5pA bias current; accepts 0V to VDD common-mode range. |
| 3 (IN+ A) | Channel A noninverting input | Matches IN− A in bias current and common-mode range; used for precision differential sensing. |
| 4 (VDD) | Positive supply | Accepts 2.7V–6V; powers both channels and shutdown logic; decoupling required near pin. |
| 5 (IN+ B) | Channel B noninverting input | Independent input for second amplifier; identical specs to IN+ A. |
| 6 (IN− B) | Channel B inverting input | Independent input with matched bias and offset characteristics to Channel A inputs. |
| 7 (OUT B) | Channel B output | Functionally identical to OUT A; supports independent dual-channel signal paths. |
| 8 (GND) | Analog ground reference | Return path for both channels and supply; must be low-impedance and separated from digital ground. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full 0V–VDD signal swing in single-supply systems, eliminating level-shifting circuitry in 3V sensor interfaces. |
| 600μA/channel quiescent current | Supports always-on monitoring in energy-harvesting or coin-cell designs without compromising bandwidth or drive strength. |
| 1000nA/channel shutdown current | Reduces system idle power by >600× vs active mode, enabling microcontroller-triggered burst-mode acquisition. |
| 2.5pA input bias current | Minimizes DC error in high-Z transducer interfaces (e.g., piezoelectric sensors, electrochemical cells) without guard traces. |
| MSOP-8 thermal pad package | Provides 4.7°C/W θJC for reliable 2.8MHz operation at ambient temperatures up to +125°C in compact PCB layouts. |

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 |
|---|---|---|---|
| TLV2472CDR | Same architecture and specs but C-suffix (0°C to +70°C), no internal ESD protection diodes on inputs. | Not qualified for automotive or extended industrial temperature use; lacks shutdown pin. | Select only for cost-sensitive commercial-grade applications where temperature range and shutdown are not required. |
| OPA2333AIDR | Zero-drift topology; 0.02μV/°C offset drift vs TLV2472AIPE4's 0.4μV/°C; higher 350μA/channel current. | Better long-term DC stability in precision thermocouple amplifiers; less suitable for high-output-drive needs. | Choose when offset drift dominates error budget over output current or shutdown capability. |
Compared with TLV2472CDR, TLV2472AIPE4 adds extended temperature support and shutdown functionality at minimal current penalty; versus OPA2333AIDR, it trades zero-drift performance for higher output drive and lower quiescent current - making it optimal for portable, power-constrained, medium-precision analog signal chains.

FAQ
What is the maximum capacitive load the TLV2472AIPE4 can drive without instability?
The TLV2472AIPE4 remains stable with capacitive loads up to 10pF directly at the output. For loads exceeding 10pF - such as ADC input capacitance or long PCB traces - Texas Instruments recommends adding a series nulling resistor (RNULL ≥20Ω) between the TLV2472AIPE4 output and the load, as documented in Figure 42 of the SLOS232E datasheet. This preserves phase margin above 61° even with 1000pF loads.
Does the TLV2472AIPE4 have built-in ESD protection on its input pins?
Yes, the TLV2472AIPE4 includes internal ESD protection diodes on both inputs, rated to withstand human-body-model (HBM) discharges up to ±2000V. However, TI explicitly warns that improper handling - such as contact with ungrounded surfaces or static-prone environments - can still cause latent damage. Always follow TI's ESD handling guidelines when soldering or probing the TLV2472AIPE4.
Can the TLV2472AIPE4 operate from a single 2.7V supply while maintaining rail-to-rail output swing?
Yes, the TLV2472AIPE4 is fully specified from 2.7V to 6V and maintains true rail-to-rail output swing down to 2.7V. At 2.7V supply and 25°C, it delivers ±10mA output current while swinging within 180mV of each rail, and ±35mA while swinging within 500mV - enabling direct interfacing with 12-bit ADCs and low-voltage microcontrollers without level-shifting circuitry.
What is the turn-on time for the shutdown feature of the TLV2472AIPE4?
The TLV2472AIPE4 has a typical amplifier turn-on time (ton) of 5μs, defined as the interval between applying a logic-high signal to the SHDN pin and the supply current reaching half its final active value. This fast wake-up supports burst-mode sensing in energy-constrained systems, allowing the TLV2472AIPE4 to settle and begin accurate amplification within microseconds after exiting shutdown.
Is the TLV2472AIPE4 pin-compatible with other members of the TLV247x family in MSOP-8 packages?
Yes, the TLV2472AIPE4 shares identical pinout and footprint with TLV2472CDGN and TLV2472IDGN in the MSOP-8 (DGN) package. All three variants use the same 8-pin configuration: OUT A, IN− A, IN+ A, VDD, IN+ B, IN− B, OUT B, GND. This allows drop-in replacement across temperature grades (C/I/A) and screening levels without PCB redesign.
