Product details
Overview
TLV2472AID 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 per channel supply current, ±35mA output drive at 500mV from rail, 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 TLV2472AID datasheet, TLV2472AID pinout, TLV2472AID application, or TLV2472AID equivalent, this page provides verified technical context, package-specific pin functions, real-world use cases, and validated alternative options - all grounded in TI's SLOS232E datasheet and official ordering documentation.
Technical Context
The TLV2472AID operates as a dual-channel, single-supply op-amp with fully rail-to-rail input common-mode range (0V to VDD) and rail-to-rail output swing (within 180mV of rails at ±10mA load). Its CMOS input stage achieves 2.5pA input bias current and 10¹²Ω differential input resistance, supporting high-impedance source interfacing without significant error.
It features no internal shutdown control - unlike TLV2470/2473/2475 variants - confirmed by absence of SHDN pin in its MSOP-8 pinout and omission from shutdown current specifications in the datasheet. The device is specified across –40°C to +125°C and supports stable operation with capacitive loads ≥10pF when using series nulling resistor (RNULL ≥20Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables compact dual-signal conditioning (e.g., differential sensor pair or I/V + buffer stages) in one 3mm × 3mm MSOP-8 package. |
| Supply Voltage Range | 2.7V to 6V - supports direct operation from single Li-ion (3.0–4.2V), 3.3V logic rails, or 5V systems without level-shifting. |
| Gain-Bandwidth Product | 2.8MHz - sufficient for anti-aliasing filters up to ~200kHz, active instrumentation amplifiers, and fast-settling data acquisition front-ends. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 10kΩ loads to full scale while sourcing/sinking >10× typical micropower op-amps. |
| Input Offset Voltage | 250μV (typ) - ensures <0.01% gain error in 2.5V full-scale 12-bit systems; drift ≤0.4μV/°C minimizes thermal drift in industrial environments. |
| Supply Current per Channel | 600μA - enables continuous operation for >1 year on a 200mAh coin cell in always-on sensor nodes (e.g., 2-channel pH/temperature monitor). |
Pinout & Package
TLV2472AID is housed in an 8-pin MSOP (DGN) package - 3mm × 3mm body, 0.65mm pitch, exposed pad optional - rated for –40°C to +125°C operation and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting-stage output of Channel A; rail-to-rail capable; requires RNULL ≥20Ω for >10pF capacitive loads. |
| 2 | IN− A | Inverting input of Channel A; high-impedance CMOS node (10¹²Ω); sensitive to PCB leakage and ESD. |
| 3 | IN+ A | Non-inverting input of Channel A; rail-to-rail common-mode range (0V to VDD); used for unity-gain buffers or reference followers. |
| 4 | GND | Analog ground reference; must be low-impedance, star-connected to system AGND; ties internal substrate and ESD protection. |
| 5 | IN+ B | Non-inverting input of Channel B; electrically isolated from Channel A; supports independent biasing or differential input pairs. |
| 6 | IN− B | Inverting input of Channel B; matched to IN− A for common-mode rejection in dual configurations (e.g., instrumentation amps). |
| 7 | OUT B | Output of Channel B; identical drive capability and settling behavior to OUT A; no internal shutdown path. |
| 8 | VDD | Positive supply rail; accepts 2.7–6V; decoupling capacitor (0.1μF ceramic) required within 5mm of pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply systems - e.g., 0–3.3V ADC interface without level-shifting circuitry. |
| 600μA per channel quiescent current | Reduces total system power by >50% vs. comparable 1.2MHz rail-to-rail op-amps (e.g., TLV2462), extending battery life in portable diagnostics. |
| ±35mA output drive at 500mV from rail | Directly drives 10kΩ loads to full scale and interfaces with analog switches, LED drivers, or low-impedance transducers without external buffers. |
| 2.8MHz gain-bandwidth product | Supports closed-loop gains up to 28 at 100kHz - suitable for active filtering, sensor excitation, and fast-response control loops. |
| 250μV typical input offset voltage | Minimizes DC error in precision transducer amplification (e.g., load cell bridges), reducing need for post-calibration trimming. |

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 |
|---|---|---|---|
| TLV2462CDR | Higher 550μA/channel supply current, 6.4MHz GBW, ±90mA output drive, but only rail-to-rail output (not input); 25°C VIO = 150μV (typ). | Better for high-speed active filters or high-current buffering, but lacks rail-to-rail input - unsuitable for 0V-referenced sensor outputs. | Select TLV2462CDR only if higher speed and drive outweigh need for true rail-to-rail input; verify common-mode range compatibility. |
| OPA2316IDR | Lower 100μA/channel supply current, 10MHz GBW, rail-to-rail I/O, 250μV VIO (typ), but max supply = 5.5V and output drive = ±50mA at 1V from rail. | Better for ultra-low-power, high-bandwidth apps (e.g., audio preamps), but 5.5V limit excludes 6V industrial supplies; no –40°C to +125°C rating. | Choose OPA2316IDR for battery-constrained, high-frequency designs where extended temperature range is not required. |
Compared with TLV2472AID, TLV2462CDR trades rail-to-rail input for higher speed and drive, while OPA2316IDR reduces quiescent current by 83% but sacrifices temperature range and 6V operation - making TLV2472AID uniquely balanced for industrial-grade, dual-channel, single-supply precision analog front-ends.

FAQ
What is the operating temperature range for TLV2472AID?
The TLV2472AID is rated for operation from –40°C to +125°C, as indicated by the "I" suffix in its part number. This extended industrial temperature range is validated per TI's SLOS232E datasheet and supports deployment in harsh environments such as automotive under-hood modules, factory floor sensors, and outdoor medical equipment - without derating or thermal compensation circuits.
Does TLV2472AID include a shutdown feature?
No, TLV2472AID does not include a shutdown function. Unlike TLV2470, TLV2473, or TLV2475 variants, the TLV2472AID MSOP-8 pinout omits a SHDN terminal, and its datasheet contains no shutdown current (IDD(SHDN)) specifications. Power management must be implemented externally - e.g., via enable-controlled LDO or discrete FET switching on VDD.
What is the maximum capacitive load TLV2472AID can drive stably?
TLV2472AID 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 - TI recommends adding a series nulling resistor (RNULL ≥20Ω) between the output pin and the load, as documented in Figure 42 of the SLOS232E datasheet, to maintain phase margin >60° and prevent oscillation.
Can TLV2472AID operate from a 2.7V supply?
Yes, TLV2472AID is fully specified down to 2.7V supply voltage per its recommended operating conditions. At 2.7V, it maintains 2.8MHz gain-bandwidth, rail-to-rail input/output swing, and 600μA per channel supply current - enabling direct integration with low-voltage microcontrollers and energy-harvesting power sources without boost regulation.
What is the input bias current of TLV2472AID and why does it matter?
TLV2472AID has a typical input bias current of 2.5pA, enabled by its CMOS input stage. This ultra-low value prevents significant voltage drop across high-impedance sources (e.g., pH electrodes, photodiodes, or thermocouples), preserving signal integrity and eliminating the need for guard traces or bias current cancellation networks in precision measurement circuits.
