Product details
Overview
TLV2453CN from Texas Instruments is a dual 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 - enabling high-precision signal conditioning in battery-powered patient monitoring and data acquisition circuits.
For engineers reviewing the TLV2453CN datasheet, TLV2453CN pinout, TLV2453CN application, or TLV2453CN equivalent, key selection criteria include shutdown functionality (16 nA/channel), rail-to-rail swing at 3 V/5 V, guaranteed operation across −40°C to 125°C, and compatibility with 14-pin PDIP packaging for through-hole prototyping and industrial control interfaces.
Technical Context
The TLV2453CN 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 1000 pF loads and achieves 106 dB PSRR at DC.
It features two independent amplifiers with dedicated shutdown control pins (pins 5 and 10), allowing channel-by-channel power gating. Shutdown mode places outputs in high-impedance state while reducing quiescent current to 16 nA per channel - critical for intermittent-sampling sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion, 3.3 V logic, and dual-supply ±1.35 V to ±3 V operation |
| Gain-Bandwidth Product | 220 kHz at VDD = 5 V - enables stable amplification of low-frequency biosignals (ECG, EEG) up to ~20 kHz |
| Supply Current per Channel | 23 µA typical - allows >1-year battery life in coin-cell–powered wearable sensors |
| Output Drive Capability | ±10 mA at VDD = 5 V - drives 500 Ω loads directly without external buffers |
| Input Offset Voltage | 20 µV typical - ensures <10 µV error in precision bridge sensor amplification |
| Shutdown Current per Channel | 16 nA typical - reduces system standby power by >99.9% versus active mode |
| Common-Mode Input Range | 0 V to VDD - accepts ground-referenced transducer outputs without level-shifting |
| PSRR | 106 dB at DC - rejects ripple from switching regulators in mixed-signal PCBs |
Pinout & Package
TLV2453CN uses a 14-pin plastic DIP (PDIP) package with 0.3-inch body width and through-hole mounting. Pin spacing is 0.1 inch (2.54 mm), compatible with standard breadboards and wave-soldered industrial assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Amplified output of first op-amp; rail-to-rail swing supports full dynamic range utilization |
| 2 | Channel 1 Inverting Input | Differential input node; high impedance (>10⁹ Ω) minimizes loading on high-Z sources |
| 3 | Channel 1 Non-Inverting Input | Reference input for follower or non-inverting configurations; matched to pin 2 for offset cancellation |
| 4 | Ground | Analog reference return path; must be star-connected to avoid noise coupling in multi-channel systems |
| 5 | Channel 1 Shutdown | Active-high digital control; pulls below 0.5 V (at 3 V) or 0.8 V (at 5 V) to disable amplifier |
| 6 | Channel 2 Non-Inverting Input | Second amplifier's positive input; electrically isolated from channel 1 for dual-sensor interfacing |
| 7 | Channel 2 Inverting Input | Second amplifier's negative input; supports differential or inverting configurations independently |
| 8 | Channel 2 Output | Second rail-to-rail output; capable of sourcing/sinking ±10 mA for driving ADC reference buffers |
| 9 | Channel 2 Shutdown | Independent enable/disable control for second channel; allows asymmetric power management |
| 10 | VDD+ | Positive supply rail; decoupling capacitor (0.1 µF) required within 5 mm for stability |
| 11–14 | No Internal Connection | Unused pins; left unconnected per TI design - no thermal or EMI benefit from grounding |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input/Output | Enables full-scale signal capture from 0 V to VDD in single-supply systems, eliminating level-shifting circuitry |
| Ultralow-Power Shutdown Mode | Reduces per-channel current to 16 nA - extends battery life in duty-cycled sensor nodes (e.g., pulse oximetry) |
| Guaranteed Operation at 3 V | Specified performance (GBW, drive, offset) validated at 3 V - ensures reliability in LiFePO₄ or coin-cell applications |
| Industrial Temperature Range | −40°C to 125°C operation supports deployment in automotive cabin modules and industrial PLC analog I/O |
| High Output Drive (±10 mA) | Drives 500 Ω loads directly - eliminates need for external buffer stages in DAC output or filter interface circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2453CDR | Same electrical specs; 8-pin SOIC package (vs. 14-pin PDIP); tape-and-reel packaging | Designed for automated SMT assembly; lacks through-hole compatibility and manual prototyping ease | Select TLV2453CDR for volume production on PCBs with space constraints and pick-and-place capability |
| OPA2340UA | Higher GBW (5.5 MHz), higher supply current (800 µA/ch), no shutdown function, same 8-pin SOIC footprint | Targeted at higher-speed signal paths (e.g., audio, active filters); unsuitable for multiday battery life requirements | Select OPA2340UA when bandwidth >100 kHz is required and power budget permits >30× higher quiescent current |
Compared with TLV2453CDR, TLV2453CN offers mechanical robustness and hand-soldering flexibility via PDIP, while OPA2340UA trades ultralow power for speed - making TLV2453CN the only choice for long-life, low-frequency, through-hole–based measurement systems.

FAQ
What is the operating temperature range for TLV2453CN?
The TLV2453CN is rated for operation from −40°C to 125°C, meeting industrial and automotive under-hood requirements. This range is fully specified in the datasheet for parameters including input offset voltage, gain-bandwidth product, and supply current - ensuring consistent performance across extreme ambient conditions without derating.
Does TLV2453CN support true rail-to-rail input and output operation?
Yes, TLV2453CN supports rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swing within 250 mV of each rail at 2.5 mA load). This capability is verified at both 3 V and 5 V supply voltages and enables full utilization of ADC input ranges in single-supply systems without external level-shifting circuitry.
How does the shutdown feature work on TLV2453CN?
The TLV2453CN has two independent shutdown pins (pin 5 for channel 1, pin 9 for channel 2), each active-high. Driving either pin ≥0.8 V (at VDD = 5 V) or ≥0.5 V (at VDD = 3 V) disables its respective amplifier, placing the output in high-impedance state and reducing supply current to 16 nA per channel - confirmed in the Electrical Characteristics table under IDD(SHDN).
What package type is TLV2453CN supplied in?
TLV2453CN is supplied in a 14-pin plastic dual in-line package (PDIP) with 0.3-inch body width. This through-hole package is explicitly listed in the "TLV2452 and TLV2453 AVAILABLE OPTIONS" table under the "PLASTIC DIP (N)" column for the "TLV2453CN" part number, supporting manual prototyping, socket-based testing, and legacy industrial board designs.
Can TLV2453CN drive capacitive loads without instability?
TLV2453CN maintains stability into capacitive loads up to 1000 pF, as confirmed by 56° phase margin measurements in the Typical Characteristics section (Figure 24). For loads >100 pF, TI recommends adding a small series resistor (10–50 Ω) between the output and capacitance to preserve phase margin - a practice validated in application note SLOA065.
