Product details
Overview
TLV2455IN from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for ultralow-power, single-supply operation in portable and battery-powered systems. It delivers 220 kHz gain-bandwidth, ±10 mA output drive, 23 µA/channel supply current, 20 µV typical input offset voltage, and operates from 2.7 V to 6 V - enabling high-precision signal conditioning in low-voltage data acquisition circuits.
For engineers reviewing the TLV2455IN datasheet, TLV2455IN pinout, TLV2455IN application, or TLV2455IN equivalent, this page provides verified electrical specifications, shutdown behavior, rail-to-rail dynamic range implications, thermal performance across −40°C to 125°C, and real-world substitution guidance for medical sensor front-ends and industrial monitoring designs.
Technical Context
The TLV2455IN implements a CMOS input stage with rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 250 mV of rails at 2.5 mA load), supporting full-scale signal utilization in 3 V systems. Its 220 kHz gain-bandwidth product and 0.11 V/µs slew rate are specified at both 3 V and 5 V supplies, with stable unity-gain operation confirmed up to 1000 pF capacitive load.
It features dual independent shutdown terminals (pins 7 and 14) that place each pair of amplifiers into high-impedance state while reducing per-channel supply current to 16 nA - critical for intermittent-sampling architectures in portable instrumentation. The device is fully characterized across −40°C to 125°C and supports single-supply operation without level-shifting circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474IN | Higher 2.8 MHz GBW and 1.5 V/µs slew rate; 600 µA/channel supply current - 26× higher quiescent power. | Targeted at higher-speed signal chains (e.g., active filters, fast-settling DAC buffers); unsuitable for multi-year battery operation. | Select TLV2474IN only when bandwidth >1 MHz is required and power budget permits >500 µA total quiescent draw. |
| MCP6004-I/P | 1 MHz GBW, 0.6 V/µs slew rate, 100 nA typical input bias current, no shutdown function, 100 µA/channel supply current. | Lacks shutdown capability and rail-to-rail output swing (clips ~80 mV from rails); lower precision (3 mV max VIO). | Choose MCP6004-I/P for cost-sensitive, non-battery applications where shutdown and ultra-low offset are not required. |
Compared with TLV2455IN, TLV2474IN trades 26× higher supply current for 12.7× greater bandwidth, while MCP6004-I/P offers lower cost but sacrifices shutdown, rail-to-rail output, and 150× worse input offset - making TLV2455IN uniquely suited for precision, ultra-low-power, multi-channel sensing.

FAQ
What is the operating temperature range for TLV2455IN?
The TLV2455IN is rated for operation from −40°C to +125°C, meeting industrial and automotive under-hood requirements. This range is validated across all key parameters including input offset voltage, supply current, and gain-bandwidth product - ensuring consistent performance in harsh environments where the TLV2455IN is deployed in PLC analog input modules and engine control sensors.
Does TLV2455IN support true rail-to-rail output swing?
Yes, the TLV2455IN delivers rail-to-rail output swing, capable of sourcing/sinking ±10 mA while maintaining output voltage within 250 mV of each supply rail. This capability is measured and guaranteed at 2.5 mA load and enables full-scale utilization of 3 V ADC references - a key design advantage of the TLV2455IN in space-constrained, single-supply data acquisition systems.
How does the shutdown feature work on TLV2455IN?
The TLV2455IN has two independent shutdown pins (pin 7 for amplifiers 1 & 2, pin 14 for amplifiers 3 & 4) that accept active-high logic. When pulled ≥2 V (at VDD = 5 V) or ≥0.5 V (at VDD = 3 V), the corresponding amplifier pair enters high-impedance state with supply current reduced to 16 nA per channel - a core energy-saving mechanism built into the TLV2455IN architecture for duty-cycled sensor nodes.
What is the typical input offset voltage of TLV2455IN?
The TLV2455IN has a typical input offset voltage of 20 µV at 25°C, with a maximum of 1300 µV across the full −40°C to 125°C range. This low offset, combined with 0.3 µV/°C drift, makes the TLV2455IN suitable for high-accuracy applications such as medical ECG front-ends and precision bridge amplifiers where offset error directly impacts measurement fidelity.
Which package type is used for TLV2455IN?
The TLV2455IN uses a 16-pin plastic DIP (N) package with 0.3-inch body width and through-hole leads. This package provides robust thermal performance (θJA = 78°C/W), mechanical stability for industrial environments, and compatibility with legacy manufacturing processes - distinguishing the TLV2455IN from surface-mount variants like TLV2455IPW.
