Texas Instruments TLV2453AINE4

Overview

TLV2453AINE4 from Texas Instruments is a dual-channel rail-to-rail input/output operational amplifier optimized for ultralow-power, low-voltage portable systems. It delivers 220 kHz gain-bandwidth, 23 µA/channel supply current, ±10 mA output drive, 20 µV typical input offset voltage, and operates from 2.7 V to 6 V - enabling precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.

For engineers reviewing the TLV2453AINE4 datasheet, TLV2453AINE4 pinout, TLV2453AINE4 application, or TLV2453AINE4 equivalent, key selection criteria include its shutdown capability (16 nA/channel), rail-to-rail swing under 2.5-mA load, −40°C to 125°C industrial temperature range, and compatibility with single-supply 3 V/5 V systems requiring high PSRR (106 dB) and CMRR (80 dB).

Technical Context

The TLV2453AINE4 implements a complementary input stage enabling true rail-to-rail common-mode input range (0 V to VDD) and output swing within 250 mV of both rails at 2.5 mA. Its internal architecture supports stable unity-gain operation with 56° phase margin into 1000 pF loads.

Shutdown control is active-low: driving SHDN ≤ 0.5 V (at VDD = 3 V) or ≤ 0.8 V (at VDD = 5 V) places outputs in high-impedance state and reduces quiescent current to 16 nA/channel. The device is fully specified across −40°C to 125°C and supports single-supply operation without split-rail requirements.

Key Specifications

Pinout & Package

TLV2453AINE4 is housed in a 14-pin plastic DIP (dual in-line package) with 0.300-inch body width, through-hole mounting, and industry-standard pin spacing (0.100 inch). This package supports manual soldering, prototyping, and legacy board designs requiring axial lead compatibility.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel rail-to-rail op-amp applications.

Compared with TLV2453CDR, TLV2453AINE4 offers guaranteed −40°C to 125°C operation and dual independent shutdown controls but requires larger DIP footprint; versus OPA2333AIDR, it trades zero-drift precision for lower cost, shutdown capability, and wider supply range - making it optimal for battery-gated sensor nodes where power sequencing matters more than sub-µV drift.

Availability

TLV2453AINE4 is available at Aetrix Electronics and suitable for portable medical equipment, industrial sensor interfaces, and low-power data loggers requiring stable component supply across extended temperature ranges and long production lifecycles.

Supply support for TLV2453AINE4 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

FAQ

What is the operating temperature range for TLV2453AINE4?

The TLV2453AINE4 is rated for operation from −40°C to +125°C, meeting industrial and automotive under-hood ambient requirements. This range is validated across all electrical parameters including input offset voltage, supply current, and gain-bandwidth product - ensuring consistent performance in harsh thermal environments without derating.

Does TLV2453AINE4 support true rail-to-rail input and output?

Yes, TLV2453AINE4 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 is achieved via complementary input differential pairs and Class AB output stage - enabling full utilization of 3 V or 5 V supplies in single-ended configurations.

How does the shutdown feature work on TLV2453AINE4?

TLV2453AINE4 has two independent active-low shutdown pins: pin 11 (1SHDN) and pin 13 (2SHDN). When pulled ≤0.5 V (at VDD = 3 V) or ≤0.8 V (at VDD = 5 V), the corresponding amplifier enters shutdown mode, disabling output stage and reducing supply current to 16 nA/channel while placing output in high-impedance state.

What is the maximum capacitive load TLV2453AINE4 can drive stably?

TLV2453AINE4 maintains 56° phase margin with up to 1000 pF capacitive load when configured as unity-gain follower (RL = 10 kΩ). For loads >100 pF, a series resistor (10–100 Ω) between output and capacitance is recommended to preserve stability in high-speed settling applications.

Is TLV2453AINE4 pin-compatible with other TLV245x variants?

No - TLV2453AINE4 uses a 14-pin DIP package with dedicated shutdown pins and NC positions, whereas TLV2453CD (SOIC-8) and TLV2453IDGK (MSOP-10) have different pin counts, assignments, and no shutdown functionality. Direct replacement requires PCB redesign and schematic updates.
