Product details
Overview
TLV2454CN from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for ultralow-power, low-voltage portable applications. It delivers 220 kHz gain-bandwidth, ±10 mA output drive, 23 µA/channel supply current, and operates from 2.7 V to 6 V. Its rail-to-rail swing enables full dynamic range in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2454CN datasheet, TLV2454CN pinout, TLV2454CN application, or TLV2454CN equivalent, key selection criteria include its 14-pin PDIP package, shutdown-free architecture (unlike TLV2450/3/5), 20 µV typical input offset, 106 dB PSRR, and guaranteed operation across 0°C to 70°C industrial range.
Technical Context
The TLV2454CN 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 internal architecture supports stable unity-gain operation with 56° phase margin into 1 nF capacitive loads.
It features no shutdown control terminal-distinguishing it from TLV2450/3/5-and draws only 23 µA per channel at 3 V or 5 V supply. Input bias current remains below 5 nA across temperature, enabling high-impedance sensor interfacing without significant error.
Key Specifications

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 |
|---|---|---|---|
| TLV2454CD | Same electrical specs but in SOIC-14 package; 1.5 mm height vs. PDIP's 3.3 mm; thermal resistance θJA = 122.3°C/W vs. 78°C/W. | Suitable for surface-mount production; not compatible with through-hole sockets or hand-soldered prototypes. | Select TLV2454CD for automated assembly; TLV2454CN remains optimal for breadboarding, legacy DIP layouts, or high-reliability through-hole deployments. |
| OPA2348AIDR | Lower 45 µA/channel supply current, 1 MHz GBW, but only dual-channel; no PDIP option; specified down to −40°C. | Requires two devices for quad functionality; better for higher-speed, lower-precision applications where size matters more than pin count. | Choose OPA2348AIDR when bandwidth >500 kHz is needed and dual-channel suffices; TLV2454CN provides true quad integration in DIP with superior low-offset stability. |
Compared with TLV2454CD and OPA2348AIDR, the TLV2454CN uniquely combines quad-channel functionality, through-hole PDIP packaging, 20 µV offset, and 23 µA/channel consumption-making it irreplaceable for cost-sensitive, serviceable, or legacy-compatible low-power analog designs.

FAQ
What is the operating temperature range for the TLV2454CN?
The TLV2454CN is rated for 0°C to 70°C ambient operation (C-suffix device). It is fully specified across this range for parameters including input offset voltage, supply current, and gain-bandwidth product. The device does not support extended industrial (−40°C to 125°C) operation-those variants carry an 'I' or 'AI' suffix (e.g., TLV2454IN).
Does the TLV2454CN include a shutdown feature?
No, the TLV2454CN does not include a shutdown terminal. Unlike TLV2450, TLV2453, and TLV2455, the TLV2454 variant omits shutdown logic entirely. All four amplifiers remain active whenever VDD is applied. This simplifies design in always-on applications but precludes dynamic power gating.
What package type is used for the TLV2454CN?
The TLV2454CN uses a 14-pin plastic dual in-line package (PDIP-N) with 0.3-inch body width and 0.1-inch pin pitch. It is a through-hole package intended for prototyping, legacy systems, and applications requiring mechanical robustness or socket-based field replacement.
Can the TLV2454CN drive capacitive loads?
Yes-the TLV2454CN maintains stability with up to 1 nF capacitive loads, as confirmed by 56° phase margin measurements at CL = 1000 pF. For loads >100 pF, a small series resistor (10–50 Ω) at the output is recommended to isolate capacitance and preserve settling time performance in precision applications.
How does the TLV2454CN compare to the TLV2452 in terms of channel count and package?
The TLV2454CN is a quad-channel op-amp in 14-pin PDIP, whereas the TLV2452 is a dual-channel device offered in 8-pin SOIC, MSOP, or PDIP. Both share identical per-channel specifications (23 µA, 220 kHz GBW, rail-to-rail I/O), but TLV2454CN integrates twice the functionality in the same footprint-reducing component count and PCB area in multi-channel designs.
