Product details
Overview
TLV2454AIN 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 TLV2454AIN datasheet, TLV2454AIN pinout, TLV2454AIN application, or TLV2454AIN equivalent, this page provides verified electrical specs, TSSOP-14 package mapping, shutdown behavior, rail-to-rail dynamic range implications, and direct alternatives for low-power analog signal chain design.
Technical Context
The TLV2454AIN 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). Its 220 kHz gain-bandwidth product and 0.11 V/µs slew rate support stable unity-gain buffering and low-frequency instrumentation amplification without phase reversal.
It features internal compensation, no shutdown terminal (unlike TLV2450/3/5), and is fully specified across −40°C to 125°C. Input offset voltage is 300 µV (max) at 25°C, with PSRR of 106 dB and CMRR of 80 dB at VDD = 5 V - confirming robust performance in noisy mixed-signal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion, 3.3 V, and 5 V systems without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - enables stable DC-coupled amplification up to ~20 kHz with gain ≥10. |
| Supply Current per Channel | 23 µA - allows four op-amps to consume <100 µA total, critical for multi-channel sensor nodes. |
| Output Drive Capability | ±10 mA - drives 500 Ω loads directly, eliminating external buffers in low-speed DAC output stages. |
| Input Offset Voltage | 300 µV (max at 25°C) - ensures <0.01% error in 30 mV full-scale biomedical signal amplification. |
| Rail-to-Rail I/O | Inputs accept 0 V to VDD; outputs swing to within 250 mV of rails at 2.5 mA - maximizes dynamic range in 3 V systems. |
| PSRR / CMRR | 106 dB PSRR, 80 dB CMRR - rejects power-supply ripple and common-mode noise in ECG/EEG front-ends. |
Pinout & Package
TSSOP-14 package (4.4 mm × 5.0 mm, 0.65 mm pitch), RoHS-compliant, rated for −40°C to 125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Output (OUT1–OUT4) | Amplified output terminals; each capable of ±10 mA sourcing/sinking into resistive loads. |
| 2, 6, 10, 14 | Inverting Input (IN−1–IN−4) | Differential input node; rail-to-rail common-mode range supports ground-referenced inputs. |
| 3, 7, 11, 12 | Non-Inverting Input (IN+1–IN+4) | Differential input node; identical rail-to-rail specification as IN− pins. |
| 4 | GND | Analog ground reference; must be low-impedance connection to minimize noise coupling. |
| 8 | VDD+ | Positive supply rail; decoupling capacitor (0.1 µF) required adjacent to pin for stability. |
| NC (Pins 11 & 12) | No Connection | Internally unconnected; must remain floating - no PCB trace or thermal pad connection. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input/Output | Enables full 0–VDD signal swing in single-supply configurations, preserving SNR in 3 V data acquisition. |
| 23 µA/Channel Quiescent Current | Permits continuous operation of all four amplifiers on coin-cell batteries for >1 year in sleep-aware systems. |
| 220 kHz Gain-Bandwidth | Supports anti-aliasing filtering, sensor excitation, and precision buffer stages without bandwidth compromise. |
| ±10 mA Output Drive | Drives 500 Ω loads directly - eliminates need for external driver stages in thermocouple or strain gauge interfaces. |
| −40°C to 125°C Operation | Validated for automotive cabin sensors, industrial process monitors, and outdoor environmental nodes. |

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 |
|---|---|---|---|
| TLV2454CDR | Same silicon, SOIC-14 package, 0°C to 70°C temp range, 23 µA/channel, no shutdown. | Lower-cost option for commercial-grade consumer devices where extended temperature is not required. | Select when operating ambient stays within 0–70°C and board space allows larger SOIC footprint. |
| OPA2333PWR | Zero-drift architecture, 17 µA/channel, 350 kHz GBW, 0.02 µV/°C drift, but only dual-channel (2 amps). | Superior DC accuracy for long-term sensor calibration; requires two packages to match TLV2454AIN's quad count. | Select when ultra-low drift (<0.1 µV/°C) and sub-µV offset dominate over channel density and cost. |
Compared with TLV2454CDR, TLV2454AIN offers extended temperature support and smaller TSSOP-14 footprint; compared with OPA2333PWR, it trades zero-drift precision for higher channel count and lower unit cost in battery-constrained designs.

FAQ
What is the operating temperature range of the TLV2454AIN?
The TLV2454AIN is rated for operation from −40°C to +125°C, as confirmed by TI's SLOS218F datasheet Section "Recommended Operating Conditions". This extended range supports deployment in automotive under-hood sensors, industrial control cabinets, and outdoor environmental monitoring where ambient extremes occur. The device maintains full specification compliance - including 23 µA/channel supply current and 220 kHz gain-bandwidth - across this entire range.
Does the TLV2454AIN include a shutdown pin?
No, the TLV2454AIN does not include a shutdown pin. Unlike TLV2450, TLV2453, and TLV2455 variants, the TLV2454AIN is a fixed-function quad op-amp with no enable/shutdown control terminal. Its pinout (TSSOP-14) contains four independent amplifier sections, GND, VDD+, and NC pins - no SHDN functionality is implemented or supported. For shutdown capability, consider TLV2455AIN instead.
What is the maximum output current capability of each amplifier in the TLV2454AIN?
Each amplifier in the TLV2454AIN delivers ±10 mA output current into resistive loads, as specified in the "Electrical Characteristics" table (VDD = 5 V, VO = 0.5 V from rail, 25°C). This allows direct driving of 500 Ω loads at full swing and supports active filtering, LED biasing, and low-speed DAC output buffering without external transistors - a key advantage over older micropower op-amps limited to ±1–2 mA.
Can the TLV2454AIN operate from a single 3.3 V supply?
Yes, the TLV2454AIN is fully specified for single-supply operation from 2.7 V to 6 V, including 3.3 V. At 3.3 V, it maintains rail-to-rail input (0 V to 3.3 V common-mode range) and rail-to-rail output (swings to within 250 mV of both rails at 2.5 mA), delivering 220 kHz gain-bandwidth and 23 µA/channel quiescent current. This makes it ideal for modern 3.3 V microcontroller-based sensor interfaces.
What package type is used for the TLV2454AIN?
The TLV2454AIN uses a 14-pin Thin Shrink Small Outline Package (TSSOP-14), measuring 4.4 mm × 5.0 mm with 0.65 mm lead pitch. This compact, surface-mount package supports high-density PCB layouts and is RoHS-compliant. Pinout matches the standard TLV2454 family layout shown in Figure 7 of the SLOS218F datasheet, with GND on Pin 4 and VDD+ on Pin 8.
