Product details
Overview
TLV2450AIP 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, ±10 mA output drive, and 23 µA supply current per channel across 2.7 V to 6 V operation, with shutdown capability reducing current to 16 nA/channel. It is used in patient monitoring front-ends where rail-to-rail swing maximizes dynamic range at 3 V supply.
For engineers reviewing the TLV2450AIP datasheet, TLV2450AIP pinout, TLV2450AIP application, or TLV2450AIP equivalent, key selection criteria include shutdown control timing (836 ns turnoff), input offset voltage (≤1000 µV over full temperature range), rail-to-rail I/O performance at 3 V, and SOT-23-6 thermal resistance (θJA = 294.3°C/W).
Technical Context
The TLV2450AIP employs a CMOS input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing within 250 mV of each rail under 2.5 mA load. Its internal shutdown logic asserts high-impedance output and reduces quiescent current to 16 nA/channel when SHDN is pulled low relative to GND.
It operates across −40°C to +125°C, fully specified at both 3 V and 5 V supplies, with PSRR of 106 dB and CMRR of 76–89 dB. The amplifier maintains stable unity-gain operation with up to 1000 pF capacitive load, exhibiting 56° phase margin and 7 dB gain margin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion (3.0–3.7 V) and dual-cell alkaline (3.0–4.5 V) battery systems without regulation. |
| Gain-Bandwidth Product | 220 kHz - enables stable DC-coupled sensor amplification and low-frequency filtering (e.g., ECG bandwidth ≤ 100 Hz) with margin. |
| Supply Current (Active) | 23 µA/channel - allows >1-year battery life in always-on wearable sensors drawing <1 µA average system current. |
| Supply Current (Shutdown) | 16 nA/channel - reduces standby power to negligible levels during sleep modes in portable medical devices. |
| Input Offset Voltage | ≤1000 µV (−40°C to +125°C) - ensures sub-mV DC accuracy in precision biopotential signal conditioning without trimming. |
| Output Drive | ±10 mA - drives 10 kΩ loads to rail while maintaining linearity, sufficient for driving ADC reference buffers or small-signal transducers. |
| Rail-to-Rail I/O | Yes - preserves full 3 V input dynamic range and delivers 0.07–4.97 V output swing at 5 V, maximizing SNR in low-voltage data acquisition. |
Pinout & Package
TLV2450AIP is housed in an 8-pin plastic DIP (PDIP) package with 0.300-inch body width and standard through-hole footprint. Pin spacing is 0.100 inch, compatible with legacy PCB layouts and manual prototyping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - left unconnected; no routing or grounding required. |
| 2 | IN− | Inverting input - accepts differential or single-ended feedback signals; high-impedance CMOS node. |
| 3 | IN+ | Non-inverting input - connects to sensor output or reference; rail-to-rail common-mode range (0 V to VDD). |
| 4 | GND | Analog ground reference - must be tied to system AGND plane with low-inductance path to minimize noise coupling. |
| 5 | SHDN | Active-low shutdown control - pulls below 0.5 V (at 3 V supply) or 0.8 V (at 5 V supply) to enter ultra-low-power mode. |
| 6 | VDD+ | Positive supply - accepts 2.7–6 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm of this pin. |
| 7 | OUT | Amplifier output - delivers rail-to-rail voltage swing; capable of sourcing/sinking ±10 mA into resistive loads. |
| 8 | NC | No internal connection - left unconnected; no routing or grounding required. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2450CDR | SOT-23-6 package, same electrical specs, 0°C to 70°C temp range, tape-and-reel delivery | Lacks extended temperature rating; unsuitable for automotive or industrial environments above 70°C | Select TLV2450CDR only for cost-sensitive consumer designs with ambient <70°C and surface-mount assembly requirements. |
| OPA333AIDBVR | Zero-drift architecture, 0.1 µV/°C drift, 17 µA supply current, 350 kHz GBW, SOT-23-5 | Higher precision but no shutdown pin; requires external enable circuitry for ultra-low-power sleep | Choose OPA333AIDBVR when sub-µV offset stability over temperature is mandatory, and shutdown functionality can be implemented externally. |
Compared with TLV2450CDR, TLV2450AIP offers guaranteed −40°C to +125°C operation in through-hole PDIP, simplifying qualification for harsh environments; versus OPA333AIDBVR, it trades zero-drift precision for integrated shutdown and lower system-level BOM count in battery-constrained applications.

FAQ
What is the maximum operating temperature range for TLV2450AIP?
The TLV2450AIP is rated for operation from −40°C to +125°C, as confirmed by its 'A' temperature suffix and full characterization in the datasheet across this range. This specification applies to all electrical parameters including input offset voltage, supply current, and gain-bandwidth product, making TLV2450AIP suitable for under-hood automotive or industrial edge-node deployments where ambient temperatures exceed 85°C.
Does TLV2450AIP support true rail-to-rail input and output operation?
Yes, TLV2450AIP 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 under 2.5 mA load). At VDD = 3 V, the output delivers 0.09–2.95 V; at VDD = 5 V, it delivers 0.07–4.97 V. This capability is explicitly verified in the Electrical Characteristics tables for both 3 V and 5 V conditions, ensuring full dynamic range utilization in low-voltage systems.
What is the shutdown current consumption of TLV2450AIP?
The TLV2450AIP draws 16 nA per channel in shutdown mode, measured at 25°C with SHDN pulled low relative to GND. Over the full −40°C to +125°C range, shutdown current remains ≤70 nA for the 'A' grade, as documented in the Electrical Characteristics table. This ultra-low value enables multi-year battery standby in intermittent-sampling applications without significant capacity loss.
How does the gain-bandwidth product of TLV2450AIP vary with supply voltage?
The gain-bandwidth product of TLV2450AIP increases slightly with supply voltage: 200 kHz at 3 V and 220 kHz at 5 V (typical, 25°C). This behavior is confirmed in the Operating Characteristics tables and Figure 25, showing monotonic improvement from 180 kHz at 2.7 V to 220 kHz at 6 V. Designers can rely on ≥200 kHz GBW across the entire 2.7–6 V range for stable closed-loop performance.
Is TLV2450AIP pin-compatible with other devices in the TLV245x family?
No, TLV2450AIP is not pin-compatible with other TLV245x variants due to its unique 8-pin PDIP configuration with two NC pins and dedicated SHDN. TLV2451 uses identical pinout but lacks shutdown; TLV2452/2453 use MSOP-8/10 with different pin assignments. The TLV2450AIP pinout is specific to the PDIP-8 package and must be laid out accordingly-no shared footprint exists across the family.
