Product details
Overview
TLV2461IDBVT from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for low-power portable and automotive applications. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage - enabling high-fidelity signal buffering in ADC front-ends and sensor interfaces operating from 2.7 V to 6 V.
For engineers reviewing the TLV2461IDBVT datasheet, TLV2461IDBVT pinout, TLV2461IDBVT application, or TLV2461IDBVT equivalent, this device supports precision analog signal conditioning in space-constrained industrial and automotive systems where rail-to-rail swing, low quiescent current, and shutdown capability (0.3 µA/channel) are critical selection criteria.
Technical Context
The TLV2461IDBVT employs a CMOS input stage with rail-to-rail common-mode input range extending beyond supply rails (0 V to VDD), paired with a robust output stage capable of sourcing/sinking ±80 mA while maintaining rail-to-rail swing. Its 6.4 MHz bandwidth and 1.6 V/µs slew rate are achieved at only 500 µA per channel, balancing AC performance and micropower operation.
It integrates a dedicated SHDN pin that places the amplifier in ultralow-current shutdown mode (0.3 µA/channel) while forcing the output into high-impedance state - a feature confirmed for TLV2461 and shared across TLV2460/3/5 variants. The device is specified over −40°C to +125°C and qualified for automotive-grade reliability.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461CDR | Same architecture and pinout; rated for 0°C to 70°C (C-suffix) instead of −40°C to 125°C (I-suffix). | Lacks automotive temperature qualification and extended reliability screening. | Select when cost sensitivity outweighs extended temperature or automotive qualification requirements. |
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV/°C offset drift vs TLV2461IDBVT's 2 µV/°C; 17 µV max offset vs 1500 µV max. | Better DC precision but higher 17 µA supply current and no shutdown pin. | Choose for ultra-low drift applications where power budget permits and shutdown is not required. |

FAQ
What is the operating temperature range for TLV2461IDBVT?
The TLV2461IDBVT is rated for operation from −40°C to +125°C (I-suffix), meeting automotive-grade thermal requirements. This range is validated per TI's qualification standards and supported by electrical specifications across the full interval, including input offset voltage (max 1700 µV), supply current (max 0.9 mA), and output drive capability.
Does TLV2461IDBVT include a shutdown function?
Yes, TLV2461IDBVT includes a dedicated SHDN pin (Pin 5 in DBV package). When pulled below 0.7 V, it disables the amplifier core and reduces supply current to 0.3 µA/channel while placing the output in high-impedance state - a feature explicitly documented for TLV2461 in the datasheet's "Micropower Shutdown Mode" section.
What is the maximum capacitive load TLV2461IDBVT can drive stably?
TLV2461IDBVT maintains ≥30° phase margin with loads up to 160 pF when driving a 10 kΩ resistive load, as verified in Figure 36 of the datasheet. For larger capacitive loads, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to preserve stability without degrading bandwidth.
Can TLV2461IDBVT operate from a single 3.3 V supply?
Yes, TLV2461IDBVT operates from a single supply between 2.7 V and 6 V. At 3.3 V, it delivers rail-to-rail input range (0 V to 3.3 V), output swing within 100 mV of each rail, 6.4 MHz GBW, and 1.6 V/µs slew rate - fully supporting precision signal conditioning in modern 3.3 V microcontroller-based systems.
Is TLV2461IDBVT pin-compatible with other TLV246x variants?
No - TLV2461IDBVT (SOT-23-5) is not pin-compatible with TLV2462 (8-pin SOIC/MSOP), TLV2463 (10-pin MSOP), TLV2464 (14-pin TSSOP), or TLV2465 (16-pin TSSOP). Its 5-pin DBV footprint is unique to the single-channel TLV2460/TLV2461 variants, with TLV2460 adding SHDN on Pin 5 and TLV2461 relocating SHDN to Pin 1 in alternate packages (not DBV).
