Product details
Overview
TLV2455IPWR from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for ultralow-power, low-voltage portable systems. It delivers 220 kHz gain-bandwidth, ±10 mA output drive, 23 µA/channel supply current, and operates from 2.7 V to 6 V - enabling high-precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2455IPWR datasheet, TLV2455IPWR pinout, TLV2455IPWR application, or TLV2455IPWR equivalent, key selection criteria include shutdown current (16 nA/channel), rail-to-rail swing capability, 20 µV typical input offset voltage, and TSSOP-16 packaging for space-constrained PCB layouts.
Technical Context
The TLV2455IPWR integrates four independent amplifiers with individual shutdown control per pair (pins 1/2SHDN and 3/4SHDN), enabling selective channel power gating. Its rail-to-rail input stage uses complementary differential pairs, while the output stage employs Class AB push-pull architecture to sustain ±10 mA into loads while swinging within 250 mV of each rail at 2.5 mA.
Designed for single-supply operation down to 2.7 V, it features 106 dB PSRR and 80 dB CMRR at 25°C, with full specification across −40°C to 125°C. The 220 kHz GBW and 0.11 V/µs slew rate support stable unity-gain buffering and low-frequency instrumentation amplification without phase margin degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports direct connection to Li-ion, 3.3 V, and 5 V rails without regulation. |
| Supply Current per Channel | 23 µA - enables multi-channel sensing nodes with >1-year battery life on coin cells. |
| Gain-Bandwidth Product | 220 kHz - sufficient for anti-aliasing filters, sensor amplification, and 12-bit ADC drivers up to ~10 kHz. |
| Input Offset Voltage (typ) | 20 µV - ensures <0.1% error in 200 mV full-scale medical sensor outputs. |
| Output Drive | ±10 mA - drives 500 Ω loads directly, eliminating external buffers in analog front-ends. |
| Rail-to-Rail I/O | Swings within 250 mV of rails at 2.5 mA - maximizes dynamic range in 3 V systems. |
| Shutdown Current | 16 nA/channel - reduces quiescent power by >1400× when inactive. |
Pinout & Package
TSSOP-16 package with 0.65 mm pitch, 5.0 mm × 4.4 mm body, and exposed thermal pad (not electrically connected). RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT, 2OUT, 3OUT, 4OUT | Amplifier output terminals | Each drives ±10 mA; rail-to-rail swing enables full utilization of 3 V ADC reference. |
| 1IN−, 2IN−, 3IN−, 4IN− | Inverting inputs | High-impedance (>10⁹ Ω) differential inputs compatible with high-Z sensors. |
| 1IN+, 2IN+, 3IN+, 4IN+ | Non-inverting inputs | Support rail-to-rail common-mode range (0 V to VDD) for single-supply biasing. |
| VDD+ | Positive supply | Accepts 2.7–6 V; PSRR of 106 dB minimizes noise coupling from noisy digital supplies. |
| GND | Ground reference | Common return for all channels and shutdown logic; decoupling required within 5 mm. |
| 1/2SHDN, 3/4SHDN | Channel pair shutdown controls | Active-high logic; pulls outputs to high-Z and cuts supply current to 16 nA/channel. |
| NC (pins 5, 9, 12, 13) | No internal connection | Not bonded; must remain unconnected to avoid parasitic coupling or mechanical stress. |
Key Features
| Feature | Design Value |

| Ultralow 23 µA/channel supply current | Permits integration of four precision op-amps in energy-harvesting or wearable devices without compromising battery runtime. |
| 16 nA/channel shutdown mode | Allows dynamic power scaling-e.g., disabling unused ECG channels during sleep cycles without firmware overhead. |
| 220 kHz gain-bandwidth at 23 µA | Delivers 10× higher AC performance than legacy micropower op-amps (e.g., TLC27L4), enabling faster settling in sensor interfaces. |

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 |
|---|---|---|---|
| TLV2474IPWR | Higher supply current (600 µA/channel), 2.8 MHz GBW, no shutdown pins | Targeted at higher-speed, higher-power applications where bandwidth >1 MHz is required | Select TLV2474IPWR only when 220 kHz GBW is insufficient and battery life is secondary to speed. |
| MCP6004-E/ST | No shutdown function, 1 µA/channel supply current, 1 MHz GBW, 4.5 mV max VIO | Optimized for ultra-low-power, cost-sensitive consumer electronics with relaxed offset requirements | Choose MCP6004-E/ST for sub-1 µA systems where 20 µV offset is not mandatory and shutdown is unnecessary. |
Compared with TLV2455IPWR, TLV2474IPWR trades 26× higher quiescent power for 13× greater bandwidth and no power management; MCP6004-E/ST reduces supply current by 96% but sacrifices 100× higher input offset and lacks shutdown - making TLV2455IPWR the sole option balancing precision, power gating, and industrial temperature range.

FAQ
What is the operating temperature range for TLV2455IPWR?
The TLV2455IPWR 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, supply current, and gain-bandwidth product - ensuring reliability in harsh environments where the TLV2455IPWR is deployed in patient monitors and motor control feedback circuits.
Does TLV2455IPWR support true rail-to-rail input and output operation?
Yes, TLV2455IPWR supports 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 at both 3 V and 5 V supplies, enabling full utilization of ADC reference voltages in single-supply 3.3 V systems - a core design advantage of the TLV2455IPWR over non-RRIO alternatives.
How does the shutdown feature work on TLV2455IPWR?
The TLV2455IPWR implements dual-pair shutdown: pins 1/2SHDN control amplifiers 1 and 2, while pins 3/4SHDN control amplifiers 3 and 4. When driven high (≥2 V at VDD = 5 V), each pair enters shutdown, reducing supply current to 16 nA/channel and placing outputs in high-impedance state. This allows independent power gating - critical for dynamic power management in the TLV2455IPWR-based multichannel sensor hubs.
What is the typical input offset voltage of TLV2455IPWR?
The typical input offset voltage of TLV2455IPWR is 20 µV at 25°C, with a maximum of 1300 µV across the full −40°C to 125°C temperature range. This low offset is measured under standard test conditions (VDD = 3 V or 5 V, RL = 10 kΩ) and directly enables high-accuracy amplification in precision applications such as ECG front-ends and bridge sensor interfaces where the TLV2455IPWR is commonly applied.
Which package type is used for TLV2455IPWR?
TLV2455IPWR uses the TSSOP-16 (PW) package: 16-pin thin shrink small-outline package with 0.65 mm lead pitch, 5.0 mm × 4.4 mm body dimensions, and exposed thermal pad. This package is explicitly listed in the "TLV2454 and TLV2455 AVAILABLE OPTIONS" table of the datasheet and is optimized for automated assembly and thermal performance in dense PCB layouts where the TLV2455IPWR is integrated.
