Product details
Overview
TLV2453AIN 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, ±10 mA output drive, 23 µA/channel supply current, and operates from 2.7 V to 6 V. It is used in patient monitoring front-ends where rail-to-rail swing maximizes dynamic range at 3 V supply.
For engineers reviewing the TLV2453AIN datasheet, TLV2453AIN pinout, TLV2453AIN application, or TLV2453AIN equivalent, key selection criteria include shutdown functionality (16 nA/channel), −40°C to 125°C industrial temperature rating, and 10-pin MSOP package with verified dual-channel RRIO performance.
Technical Context
The TLV2453AIN implements a CMOS input stage 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 shutdown control (SHDN) places outputs in high-impedance state and reduces quiescent current to 16 nA per channel.
It features 106 dB power supply rejection ratio (PSRR) and 89 dB common-mode rejection ratio (CMRR) at 25°C with VDD = 5 V, supporting precision signal conditioning in noisy battery-powered environments. The device is fully specified across −40°C to 125°C and supports single-supply operation down to 2.7 V.
Key Specifications

| Supply Current per Channel | 23 µA - Allows >1-year battery life in always-on medical wearables drawing <100 µA total. |
| Input Offset Voltage | 300 µV (max, full temp range) - Ensures ≤0.3 mV error in 10-bit ADC interfacing at 3.3 V full scale. |
| Output Drive Capability | ±10 mA - Drives 300 Ω loads directly, eliminating need for external buffer in analog front-ends. |
| Shutdown Current | 16 nA per channel - Reduces system standby power to nanoampere level during sleep modes. |

| 6 | VDD+ | Positive supply - Accepts 2.7–6 V; decoupling capacitor required within 1 cm for stability. |
| 7 | OUT2 | Amplifier 2 output - Independent rail-to-rail output; no crosstalk coupling to OUT1 above −90 dB. |
| 8 | IN2− | Inverting input of Amp2 - Electrically isolated from Amp1 inputs; supports dual-sensor conditioning. |
| 9 | IN2+ | Non-inverting input of Amp2 - Matches IN2−; allows simultaneous ECG and SpO₂ signal paths on one IC. |
| 10 | 2SHDN | Shutdown enable for Amp2 - Independently controllable; enables asymmetric power management per channel. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2453CDR | Same silicon, 0°C to 70°C temp grade, 10-pin MSOP, tape-and-reel packaging. | Limited to commercial temperature range; not qualified for automotive or industrial ambient extremes. | Select when cost sensitivity outweighs extended temperature requirement and board space permits same footprint. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs TLV2453AIN's 0.3 µV/°C; 35 µA/channel supply current. | Better DC precision for long-term sensor calibration; higher current draw limits battery lifetime in ultra-low-power use cases. | Choose for applications requiring sub-µV offset stability over temperature, accepting 50% higher quiescent current. |
Compared with TLV2453CDR, TLV2453AIN offers guaranteed −40°C to 125°C operation and tighter initial offset spec; versus OPA2333AIDR, it trades zero-drift precision for 35% lower supply current and simpler external component count.

FAQ
What is the operating temperature range for TLV2453AIN?
The TLV2453AIN is rated for −40°C to 125°C free-air temperature operation. All electrical specifications - including supply current, gain-bandwidth, input offset voltage, and PSRR - are guaranteed across this full industrial temperature range, making TLV2453AIN suitable for under-hood automotive sensors and factory-floor industrial transmitters.
Does TLV2453AIN support true rail-to-rail input and output operation?
Yes, TLV2453AIN supports true rail-to-rail input (common-mode range = 0 V to VDD) and rail-to-rail output (swing to within 250 mV of VDD or GND at 2.5 mA load). This capability is verified across the full −40°C to 125°C range and enables maximum dynamic range in 3 V and 5 V single-supply systems without external level-shifting circuitry.
How does the shutdown feature work on TLV2453AIN?
TLV2453AIN has two independent shutdown pins: pin 5 (1SHDN) controls amplifier 1, and pin 10 (2SHDN) controls amplifier 2. Driving either pin logic-high (≥2 V at VDD = 5 V) disables its respective amplifier, placing the output in high-impedance state and reducing supply current to 16 nA per channel. Both amplifiers remain active when SHDN pins are tied to GND.
What package type is used for TLV2453AIN and what are its thermal characteristics?
TLV2453AIN uses a 10-pin MSOP (DGS) package with exposed thermal pad. Its thermal resistance is θJA = 257.7°C/W and θJC = 54.1°C/W. At TA = 25°C, the package supports 485 mW power dissipation - sufficient for dual-channel operation at full output swing into 600 Ω loads without derating.
Can TLV2453AIN drive capacitive loads without instability?
TLV2453AIN maintains stability with capacitive loads up to 1000 pF when driving a 10 kΩ resistive load, as confirmed by phase margin ≥56° and gain margin ≥7 dB in datasheet Figure 24. For loads >100 pF, TI recommends adding a 10 Ω series resistor between output and capacitance to preserve settling time and prevent peaking.
