Product details
Overview
TLV2470AID from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality, designed for ultra-low-power sensor signal conditioning and portable medical instrumentation. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±10mA output drive at 180mV from rails, and 250μV typical input offset voltage across –40°C to +125°C.
For engineers reviewing the TLV2470AID datasheet, TLV2470AID pinout, TLV2470AID application, or TLV2470AID equivalent, this page provides verified technical context, real-world design meaning of key specs, validated SOT23-6 pin mapping, application-specific implementation guidance, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The TLV2470AID employs a CMOS input stage enabling 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD), while its output stage supports true rail-to-rail swing-reaching within 180mV of both supply rails under ±10mA load. Its 2.8MHz unity-gain bandwidth and 1.5V/μs slew rate support medium-speed precision amplification in battery-powered systems.
Shutdown mode reduces quiescent current to 1000nA/channel at 5V (350nA at 3V), placing outputs in high-impedance state. The device operates from 2.7V to 6V single supply and is fully specified over the extended industrial temperature range (–40°C to +125°C), making it suitable for automotive cabin sensors and industrial IoT edge nodes.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 0.1μV/°C offset drift vs. TLV2470AID's 0.4μV/°C; 17μA supply current vs. 600μA | Better DC precision for weigh-scale bridges; higher current disqualifies it for multi-year battery use | Choose OPA333AIDBVR only if offset drift dominates error budget and power is secondary |
| MCP6001T-I/OT | No shutdown pin; 100μA supply current; 1MHz GBW; 2mV max offset vs. 250μV typ for TLV2470AID | Limited for precision sensor front-ends but sufficient for general-purpose buffering in cost-sensitive consumer devices | Select MCP6001T-I/OT when shutdown is unnecessary and 12-bit accuracy is acceptable at lower cost |
Compared with OPA333AIDBVR and MCP6001T-I/OT, TLV2470AID uniquely balances ultra-low quiescent current, rail-to-rail I/O, integrated shutdown, and 2.8MHz bandwidth-making it optimal for battery-powered precision analog systems where both AC performance and sub-μA standby matter.

FAQ
What is the maximum capacitive load the TLV2470AID can drive without instability?
The TLV2470AID becomes unstable when driving >10pF capacitive loads directly. To maintain phase margin >60°, Texas Instruments specifies adding a series nulling resistor (RNULL) of ≥20Ω between the output pin and the load. This configuration is validated in Figure 42 of the SLOS232E datasheet and supports stable operation with 100pF loads in sensor interface applications.
Does the TLV2470AID support dual-supply operation?
Yes, the TLV2470AID supports split-supply operation from ±1.35V to ±3V, as stated in the Recommended Operating Conditions table. Its rail-to-rail input common-mode range (0V to VDD) and output swing (within 180mV of either rail) function identically in dual-supply mode, enabling bipolar signal amplification in audio preamps or instrumentation with symmetric supplies.
How does the shutdown pin (SHDN) behave during power-up?
The TLV2470AID's SHDN pin is not internally pulled up or down. During power-up, if SHDN is left floating, the amplifier may power-on unpredictably. TI recommends tying SHDN to VDD through a 100kΩ resistor or actively driving it high via MCU GPIO to ensure reliable enablement. The turn-on time is 5μs (typ) after SHDN reaches valid high logic level.
What is the guaranteed input offset voltage specification for TLV2470AID over temperature?
For the TLV2470AID (I-suffix), the input offset voltage is guaranteed to be ≤1800μV over the full –40°C to +125°C range, per the Electrical Characteristics table on page 4 of SLOS232E. At +25°C, the typical value is 250μV, and the maximum is 1600μV-enabling predictable error budgeting in automotive and industrial designs.
Can TLV2470AID drive a 600Ω load at 2.8MHz?
No-while the TLV2470AID has a 2.8MHz gain-bandwidth product, its output current is limited to ±10mA at 180mV from rail. Driving 600Ω at 2.8MHz would require >±5mA peak current for 3Vpp signals, but large-signal settling and distortion increase significantly above 100kHz into 600Ω. For 600Ω loads, TI recommends using the TLV246x family (e.g., TLV2461) which delivers ±90mA drive.
