Product details
Overview
TLV2454AIPW 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, and operates from 2.7 V to 6 V - enabling high-precision signal conditioning in low-voltage data acquisition and patient monitoring circuits.
For engineers reviewing the TLV2454AIPW datasheet, TLV2454AIPW pinout, TLV2454AIPW application, or TLV2454AIPW equivalent, key selection criteria include its rail-to-rail I/O swing at micropower consumption, shutdown capability (16 nA/channel), TSSOP-14 package footprint, and guaranteed −40°C to 125°C operation for industrial and medical-grade designs.
Technical Context
The TLV2454AIPW employs 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), enabling full dynamic range utilization in 3 V and 5 V systems. Its 220 kHz gain-bandwidth product and 0.11 V/µs slew rate support stable unity-gain buffering and low-frequency amplification without phase reversal.
It features internal compensation for unity-gain stability, 106 dB PSRR, 80 dB CMRR (typ), and 1000 Ω closed-loop output impedance at 10 kHz - making it suitable for high-impedance sensor interfaces and precision analog front-ends where power, noise, and supply rejection are critical.
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 with sub-100 µA total quiescent draw. |
| Gain-Bandwidth Product | 220 kHz - sufficient for anti-aliasing filters, sensor amplification, and low-speed DAC output buffers. |
| Output Drive Capability | ±10 mA - drives 10 kΩ loads to rail while maintaining linearity in active filters and transducer interfaces. |
| Rail-to-Rail I/O | Yes - preserves full input voltage range and maximizes ADC utilization in single-supply systems. |
| Input Offset Voltage | 300 µV (max, 25°C) - ensures <1 LSB error in 12-bit systems with 3 V reference. |

Applications
| Portable ECG Front-End | Industrial Temperature Sensor Interface |
|---|---|
Use Scenario: Amplifying microvolt-level biopotential signals from dry electrodes in battery-powered ECG patches. IC Role / Device Role / Timing Role: Quad-channel instrumentation amplifier front-end (two stages per channel), providing gain, filtering, and level-shifting before 12-bit SAR ADC sampling. Use Value: Rail-to-rail I/O preserves signal headroom across 3.3 V supply; 23 µA/channel extends 7-day battery life; 300 µV max VIO ensures <0.5% amplitude error in diagnostic-grade waveforms. | Use Scenario: Conditioning output from PT100 RTD bridges in factory-floor temperature transmitters. IC Role / Device Role / Timing Role: Precision low-noise amplifier for Wheatstone bridge excitation and differential-to-single-ended conversion. Use Value: 106 dB PSRR rejects 50/60 Hz supply noise; ±10 mA drive supports 4–20 mA loop drivers; −40°C to 125°C rating ensures calibration stability across ambient extremes. |
| Low-Power Data Logger | Medical Infusion Pump Pressure Sensing |
Use Scenario: Multi-sensor signal conditioning (thermistor, humidity, accelerometer) in solar-charged environmental monitors. IC Role / Device Role / Timing Role: Four independent sensor preamplifiers with shared VDD/GND, each configured as unity-gain buffer or non-inverting amplifier. Use Value: TSSOP-14 footprint minimizes PCB area vs. discrete SOIC solutions; shutdown mode (not available on TLV2454AIPW) is unnecessary due to ultra-low 92 µA total quiescent draw. | Use Scenario: Amplifying piezoresistive pressure transducer outputs in Class II medical infusion pumps. IC Role / Device Role / Timing Role: Primary gain stage feeding isolated sigma-delta ADC, with rail-to-rail output ensuring full-scale digitization.

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 |
|---|---|---|---|
| TLV2454IPW | Same architecture and pinout, but rated for 0°C to 70°C only; 1000 µV max VIO over full range vs. 1300 µV for TLV2454AIPW. | Suitable for commercial-grade portable instruments without extended temperature requirements. | Select TLV2454IPW only if operating ambient stays within 0°C–70°C and tighter VIO spec is not required. |
| TLV2474IPW | Higher 600 µA/channel supply current, 2.8 MHz GBW, and 1.5 V/µs slew rate - trades power for speed. | Better for active filter design or higher-frequency sensor interfaces (>10 kHz), but increases battery load 26×. | Choose TLV2474IPW when bandwidth >1 MHz is needed and power budget allows; avoid for micropower-critical designs. |
Compared with TLV2454IPW, the TLV2454AIPW adds industrial temperature qualification and tighter initial offset; compared with TLV2474IPW, it reduces supply current by 96% at the cost of 12× lower bandwidth - making TLV2454AIPW optimal for static or sub-10 kHz precision sensing where energy efficiency is paramount.

FAQ
What is the operating temperature range of the TLV2454AIPW?
The TLV2454AIPW is specified for operation from −40°C to +125°C, meeting industrial and extended-temperature medical requirements. This rating is confirmed in the "Recommended Operating Conditions" table of the SLOS218F datasheet, and applies across the full supply range (2.7 V to 6 V). The "A" suffix explicitly denotes this extended temperature grade, distinguishing it from the "C" (0°C–70°C) and "I" (−40°C–125°C, non-A grade) variants.
Does the TLV2454AIPW include a shutdown feature?
No, the TLV2454AIPW does not include a shutdown terminal. Per the Family Package Table and device description in the SLOS218F datasheet, only TLV2450, TLV2453, and TLV2455 offer shutdown functionality. The TLV2454 series - including TLV2454AIPW - is a quad op-amp without integrated shutdown control; all four channels remain active whenever powered. Shutdown current (16 nA) applies only to the designated variants.
What is the maximum output current capability of the TLV2454AIPW?
The TLV2454AIPW delivers ±10 mA output current per channel, as specified under "Output Current" in the Electrical Characteristics tables (VDD = 5 V, VO = 0.5 V from rail, 25°C). This is validated across the full operating temperature range and supports driving typical loads such as 10 kΩ ADC inputs, RC filter networks, and low-current LED bias circuits without external buffers.
Is the TLV2454AIPW pin-compatible with other TSSOP-14 quad op-amps?
The TLV2454AIPW uses a standard TSSOP-14 pinout defined in TI's SLOS218F datasheet (Page 3, "TLV2454 D, N, OR PW PACKAGE" diagram), with Channel 1–4 inputs/outputs arranged sequentially. While not drop-in compatible with unrelated families (e.g., LM324 or MCP6004), it is functionally and physically pin-compatible with TLV2454IPW and TLV2454IN - differing only in temperature grade and packaging (TSSOP vs. PDIP). Always verify pin mapping against the official schematic symbol before layout.
What is the input offset voltage specification for TLV2454AIPW at 25°C?
At 25°C, the TLV2454AIPW has a maximum input offset voltage (VIO) of 1000 µV, with a typical value of 300 µV, as stated in the "Electrical Characteristics" table for TLV245xA (Page 5, VIO row). Over the full −40°C to +125°C range, the maximum is 1300 µV. This specification is measured under standard conditions (VDD = 3 V or 5 V, VIC = VDD/2, RL = 10 kΩ) and is critical for DC-coupled precision applications like strain gauge amplification.
