Product details
Overview
TLV2454CPW 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, and 23 µA/channel supply current across 2.7 V to 6 V operation - enabling precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2454CPW datasheet, TLV2454CPW pinout, TLV2454CPW application, or TLV2454CPW equivalent, key selection criteria include rail-to-rail I/O swing at 3 V, shutdown current of 16 nA/channel, thermal stability over −40°C to 125°C, and TSSOP-14 package compatibility with high-density PCB layouts.
Technical Context
The TLV2454CPW employs CMOS input stage architecture enabling rail-to-rail common-mode input voltage range (0 V to VDD) and rail-to-rail output swing within 250 mV of each rail under 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.
It features internal compensation for unity-gain stability, 106 dB power supply rejection ratio, and 80 dB common-mode rejection ratio - all specified across full industrial temperature range. The device lacks integrated shutdown control, distinguishing it from TLV2450/3/5 variants in the same family.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2454IPW | Same electrical specs but rated for −40°C to 125°C industrial temperature range (vs. 0°C to 70°C for TLV2454CPW). | Required for automotive under-hood or industrial control cabinet deployments where ambient exceeds 70°C. | Select TLV2454IPW when extended temperature qualification is mandatory; otherwise TLV2454CPW suffices for commercial-grade portable equipment. |
| OPA2333PWR | Zero-drift architecture (0.02 µV/°C drift), lower input offset (2 µV max), but higher supply current (17 µA vs. 23 µA per channel). | Better for ultra-high-precision DC measurements (e.g., laboratory pH meters), less optimal for battery life-critical designs. | Choose OPA2333PWR only when sub-µV offset stability over temperature outweighs 30% higher quiescent power consumption. |
Compared with TLV2454IPW, the TLV2454CPW trades extended temperature rating for lower cost and qualification overhead in consumer medical devices; versus OPA2333PWR, it prioritizes micropower efficiency over zero-drift precision - making TLV2454CPW optimal for cost-sensitive, battery-operated instrumentation where 20 µV offset is acceptable.

FAQ
What is the operating temperature range for TLV2454CPW?
The TLV2454CPW is specified for operation from 0°C to 70°C (commercial grade). This range is validated per TI's SLOS218F datasheet and applies to all electrical parameters including input offset voltage, gain-bandwidth, and supply current. For extended temperature operation up to 125°C, the TLV2454IPW variant is recommended. The TLV2454CPW does not include internal shutdown circuitry, so thermal design must ensure junction temperature remains below 150°C under worst-case power dissipation.
Does TLV2454CPW support rail-to-rail input and output operation?
Yes, the TLV2454CPW supports true rail-to-rail input and output operation. Its CMOS input stage accepts common-mode voltages from 0 V to VDD, and its output swings within 250 mV of each rail while driving 2.5 mA - verified at both 3 V and 5 V supplies. This capability is explicitly confirmed in the "description" section of the SLOS218F datasheet and enables full utilization of low-voltage supply rails in portable medical and sensor applications.
What is the typical supply current per channel for TLV2454CPW?
The typical supply current per channel for TLV2454CPW is 23 µA at VDD = 3 V and TA = 25°C, as specified in the "Electrical Characteristics" table of the SLOS218F datasheet. This value increases slightly with supply voltage (up to 42 µA at 5 V) and temperature, remaining within 44 µA maximum across the full 0°C to 70°C range. The device has no shutdown mode, so this current flows continuously in normal operation.
What package type is used for TLV2454CPW?
The TLV2454CPW uses a TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body size, 0.65 mm lead pitch, with a non-electrical exposed thermal pad. This package is confirmed in the "TLV2454 and TLV2455 AVAILABLE OPTIONS" table and "TLV245x PACKAGE PINOUTS" diagram of the SLOS218F datasheet. It is distinct from SOIC-14 (D) and PDIP-14 (N) variants and requires fine-pitch reflow profile validation for reliable assembly.
Is TLV2454CPW pin-compatible with other TLV245x quad variants?
Yes, TLV2454CPW is pin-compatible with all TLV245x quad op-amps in TSSOP-14 (PW) packaging, including TLV2454IPW and TLV2455CPW. Pin functions match exactly per the "TLV2454 D, N, OR PW PACKAGE" diagram in the SLOS218F datasheet. However, TLV2455 includes dual shutdown control pins (3/4SHDN), whereas TLV2454CPW has no shutdown functionality - meaning unused shutdown pins on TLV2455 must be tied high or low in drop-in replacement scenarios.
