Product details
Overview
TLV2450IP from Texas Instruments is a single-channel rail-to-rail input/output operational amplifier optimized for ultralow-power, low-voltage portable systems. It delivers 220 kHz gain-bandwidth, 23 µA supply current per channel, ±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 TLV2450IP datasheet, TLV2450IP pinout, TLV2450IP application, or TLV2450IP equivalent, this page provides verified package mapping (8-pin PDIP), shutdown functionality details, rail-to-rail dynamic range implications, and validated alternative options for low-power analog signal chains.
Technical Context
The TLV2450IP 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 operation with capacitive loads up to 1000 pF (56° phase margin) and features an active shutdown terminal that places the output in high-impedance state while reducing supply current to 16 nA/channel.
Specified across −40°C to +125°C, it maintains 106 dB PSRR and 76–89 dB CMRR over full VDD range (2.7 V–6 V), with input bias current below 5 nA and input offset voltage drift of 0.3 µV/°C - making it suitable for high-accuracy, wide-temperature industrial sensing nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - enables direct operation from single Li-ion cell or 3.3 V/5 V rails without regulation. |
| Supply Current (per channel) | 23 µA typ - extends battery life in always-on wearable monitors and remote sensor nodes. |
| Gain-Bandwidth Product | 220 kHz - supports DC-coupled amplification and low-frequency filtering (e.g., ECG, temperature, strain gauge signals). |
| Rail-to-Rail I/O | Input: 0 V to VDD; Output: within 250 mV of rails at 2.5 mA - maximizes dynamic range in 3 V systems. |
| Shutdown Current | 16 nA/ch - reduces system standby power by >1000× versus active mode, critical for intermittent-sampling applications. |
| Input Offset Voltage | 20 µV typ - minimizes DC error in precision instrumentation amplifiers and sensor bridges. |
| Output Drive | ±10 mA - drives 10 kΩ loads directly and interfaces with ADC reference buffers or low-impedance filters. |
Pinout & Package
TLV2450IP is housed in an 8-pin plastic DIP (PDIP) package with 0.3-inch body width and through-hole mounting. Pin 1 is identified by a beveled edge or molded "U" shape.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC (No internal connection) | Not bonded; must be left unconnected or tied to GND for mechanical stability. |
| 2 | IN− | Inverting input - accepts differential or single-ended feedback configurations. |
| 3 | IN+ | Non-inverting input - used for unity-gain buffer, comparator hysteresis, or sensor excitation. |
| 4 | GND | Analog ground reference - requires low-impedance connection to system ground plane. |
| 5 | SHDN | Active-low shutdown control - driven low (<0.5 V at 3 V supply) to enter ultra-low-power mode. |
| 6 | VDD+ | Positive supply - decoupling capacitor (0.1 µF ceramic) required adjacent to pin. |
| 7 | OUT | Amplifier output - capable of sourcing/sinking ±10 mA into resistive or moderate capacitive loads. |
| 8 | NC (No internal connection) | Not bonded; electrically isolated and may be left floating or grounded. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal utilization in 3 V systems - e.g., 0–3 V sensor outputs digitized by 12-bit SAR ADCs without level-shifting. |
| Ultralow 23 µA supply current | Permits continuous operation for >1 year on a CR2032 coin cell in low-duty-cycle data loggers (e.g., environmental monitors). |
| 16 nA shutdown current | Reduces quiescent power to <50 nW - essential for energy-harvesting nodes where microamp-level leakage dominates budget. |
| 220 kHz GBW with 0.11 V/µs slew rate | Supports accurate amplification of sub-100 Hz biosignals (ECG, EEG) while rejecting 50/60 Hz interference via active filtering. |
| Specified from −40°C to +125°C | Validates performance in automotive cabin modules, industrial PLC analog inputs, and outdoor IoT enclosures without derating. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2450CDR | Same electrical specs; 5-pin SOT-23 package, 0°C to 70°C temp range, tape-and-reel packaging. | Targeted at commercial-grade, space-constrained PCBs (e.g., consumer wearables), not extended-temp industrial use. | Select TLV2450CDR only if ambient operating temperature stays within 0–70°C and board area is premium. |
| OPA333AIDR | Zero-drift architecture; 17 µV max offset (vs. 1300 µV max for TLV2450IP); 17 µA supply current; no shutdown pin. | Better DC accuracy for high-resolution weigh scales or precision thermocouple amps; lacks shutdown for ultra-low-power duty cycling. | Choose OPA333AIDR when offset drift dominates error budget and shutdown is unnecessary; avoid if <100 nA standby is mandatory. |
Compared with TLV2450IP, TLV2450CDR offers identical analog performance in a smaller footprint but sacrifices industrial temperature rating and shutdown capability, while OPA333AIDR improves DC precision at the cost of missing shutdown and higher cost - making TLV2450IP the optimal balance for battery-powered, wide-temp, low-duty-cycle systems.

FAQ
What is the operating temperature range for TLV2450IP?
The TLV2450IP is rated for operation from −40°C to +125°C, as confirmed by its 'I' suffix and the Absolute Maximum Ratings table in the official datasheet (SLOS218F). This extended industrial temperature range ensures reliable performance in automotive under-hood modules, factory-floor PLCs, and outdoor environmental sensors without thermal derating.
Does TLV2450IP support true rail-to-rail input and output?
Yes, TLV2450IP supports rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swings within 250 mV of each rail at 2.5 mA load), as specified in the device description and Electrical Characteristics tables. This capability is fully validated at both 3 V and 5 V supplies and enables maximum signal swing in low-voltage systems.
How does the shutdown function work on TLV2450IP?
The TLV2450IP's SHDN pin (Pin 5) is active-low: driving it below 0.5 V (at 3 V supply) or 0.8 V (at 5 V supply) places the amplifier in shutdown mode, reducing supply current to 16 nA/channel and forcing the output into high-impedance state. The turnoff time is 836 ns, and turnon time is 59 µs - enabling rapid wake-up in duty-cycled sensor systems.
What package type is TLV2450IP supplied in?
TLV2450IP is supplied in an 8-pin plastic DIP (PDIP) package with 0.3-inch body width, as explicitly listed in the "TLV2450 and TLV2451 AVAILABLE OPTIONS" table and confirmed by the part number suffix 'P'. It is not available in SOIC, SOT-23, or MSOP variants - those correspond to other suffixes (e.g., TLV2450IDBV = SOT-23).
Can TLV2450IP drive capacitive loads?
Yes, TLV2450IP is stable with capacitive loads up to 1000 pF, as demonstrated by its 56° phase margin in the Typical Characteristics (Figure 24). For loads >100 pF, a small series resistor (e.g., 10–50 Ω) between output and capacitance is recommended to maintain stability in high-precision ADC driver applications.
