Product details
Overview
TLV2455CPW from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for ultra-low-power, low-voltage portable systems. It delivers 220 kHz gain-bandwidth, 23 µA/channel supply current, ±10 mA output drive, 20 µV typical input offset voltage, and operates from 2.7 V to 6 V - enabling precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2455CPW datasheet, TLV2455CPW pinout, TLV2455CPW application, or TLV2455CPW equivalent, key selection criteria include shutdown current (16 nA/ch), rail-to-rail swing capability at 3 V, TSSOP-16 package thermal performance, and verified operation across −40°C to 125°C industrial temperature range.
Technical Context
The TLV2455CPW integrates four independent amplifiers with individual shutdown control per pair (pins 1/2SHDN and 3/4SHDN), supporting selective channel power gating. Its input stage uses complementary input transistors to achieve true rail-to-rail common-mode range (0 V to VDD) and output stage enables swing within 250 mV of both rails under 2.5 mA load.
Designed for single-supply operation, it features 106 dB PSRR and 80 dB CMRR at 25°C, with stable unity-gain compensation (56° phase margin into 1 nF). Shutdown mode places outputs in high-impedance state while reducing quiescent current to 16 nA per channel - critical for intermittent-sampling architectures.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2475IPW | Higher supply current (600 µA/ch), 2.8 MHz GBW, no shutdown function | Better for AC-coupled audio or higher-speed sensor interfaces where power is not constrained | Select when bandwidth >1 MHz is required and shutdown is unnecessary |
| LPV521MG/NOPB | Lower supply current (320 nA/ch), 6.5 kHz GBW, single-channel, no shutdown | Suitable for ultra-long-life single-sensor nodes where speed is secondary to energy efficiency | Choose for nanowatt applications with <10 kHz signal bandwidth requirements |

FAQ
What is the operating temperature range for TLV2455CPW?
The TLV2455CPW is specified for operation from −40°C to 125°C, meeting industrial and automotive under-hood requirements. This range is validated across all electrical parameters including input offset voltage, CMRR, and supply current - ensuring reliable performance in harsh environments where the TLV2455CPW is deployed in motor control feedback or engine sensor interfaces.
Does TLV2455CPW support true rail-to-rail input and output?
Yes, TLV2455CPW supports true rail-to-rail input (common-mode range = 0 V to VDD) and rail-to-rail output (swing within 250 mV of each rail at 2.5 mA load). This capability is confirmed in the datasheet's Electrical Characteristics tables and Typical Characteristics curves (Figures 1–2, 11–14), enabling direct interfacing with unipolar sensors and ADCs without external level-shifting circuitry.
How does the shutdown feature work on TLV2455CPW?
The TLV2455CPW implements two independent shutdown controls: pin 1/2SHDN disables amplifiers 1 and 2, while pin 3/4SHDN disables amplifiers 3 and 4. When asserted low (<0.5 V at 3 V supply), each control places its associated outputs in high-impedance state and reduces per-channel supply current to 16 nA - verified in the Electrical Characteristics table (IDD(SHDN)) and Figure 35–41 transient waveforms.
What package type is TLV2455CPW supplied in?
TLV2455CPW is supplied in a 16-pin TSSOP (Thin Shrink Small Outline Package) with 4.4 mm × 5.0 mm body and 0.65 mm lead pitch. The package includes an exposed thermal pad for enhanced heat dissipation - confirmed in the "TLV2454 and TLV2455 AVAILABLE OPTIONS" table and Package Option Addendum referenced in the datasheet.
Can TLV2455CPW operate from a single 3 V supply?
Yes, TLV2455CPW is fully specified and characterized for single-supply operation from 2.7 V to 6 V, including detailed electrical data at VDD = 3 V (pages 5–6). Its rail-to-rail input/output architecture, 23 µA/channel supply current, and 220 kHz gain-bandwidth make it ideal for 3 V battery-powered applications such as portable glucose meters and handheld gas detectors where the TLV2455CPW delivers precision amplification without voltage translation.
