Product details
Overview
TLV2450AID 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 - enabling precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2450AID datasheet, TLV2450AID pinout, TLV2450AID application, or TLV2450AID equivalent, key selection criteria include its −40°C to 125°C industrial temperature rating, 6-pin SOT-23 package with shutdown control, rail-to-rail swing under 2.5-mA load, and verified 16 nA/channel shutdown current.
Technical Context
The TLV2450AID 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). Its internal architecture supports stable unity-gain operation with 56° phase margin into 1000 pF loads and achieves 106 dB PSRR at DC.
Shutdown functionality is controlled by a dedicated SHDN pin referenced to GND, requiring VIL ≤ 0.5 V (at VDD = 3 V) or ≤ 0.8 V (at VDD = 5 V) to activate. In shutdown, output enters high-impedance state and supply current drops to 16 nA/channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion, two-cell alkaline, and regulated 3.3 V/5 V rails without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - enables stable amplification of DC–200 kHz sensor signals (e.g., ECG, thermistor bridges) with minimal phase lag. |
| Supply Current (Active) | 23 µA/channel - allows >1-year battery life in always-on wearable monitors using CR2032 cells. |
| Supply Current (Shutdown) | 16 nA/channel - reduces quiescent power by 1400×, critical for intermittent-sampling data loggers. |
| Input Offset Voltage | 300 µV (max, 25°C) - ensures <1 LSB error in 12-bit ADC interfaces with gain ≤ 10. |
| Output Drive | ±10 mA - drives 500-Ω loads directly (e.g., 1 kΩ potentiometer + 1 nF filter), eliminating buffer stages. |
| CMRR / PSRR | 76 dB / 106 dB - rejects noise from shared PCB power rails and prevents ground-loop errors in isolated sensor nodes. |
Pinout & Package
TLV2450AID is housed in a 6-pin SOT-23 package (DBV), measuring 2.9 mm × 1.6 mm × 1.1 mm, with exposed pad option not specified. Pin 1 is marked by a molded dot or beveled edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; sinks/sources ±10 mA; high-impedance during shutdown. |
| 2 (IN−) | Inverting input | CMOS input with 0.3 nA max bias current; supports differential sensing up to VDD. |
| 3 (IN+) | Non-inverting input | CMOS input with 0.3 nA max bias current; accepts signals from 0 V to VDD. |
| 4 (GND) | Analog ground reference | Return path for input common-mode and output current; must connect to clean analog ground plane. |
| 5 (SHDN) | Shutdown control | Active-low logic input; pulls to GND to enter 16 nA shutdown mode; floats high to enable. |
| 6 (VDD+) | Positive supply | Accepts 2.7–6 V; decoupling capacitor (100 nF) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3 V systems - e.g., 0–3 V output from 0–3 V sensor output without clipping. |
| Ultralow 23 µA supply current | Reduces self-heating to <0.1°C in sealed enclosures, preserving accuracy of temperature-sensitive measurements. |
| Dedicated shutdown pin | Allows microcontroller GPIO to disable amplifier between ADC conversions, cutting system idle power by >99%. |
| 220 kHz GBW at 23 µA | Outperforms competing micropower op-amps (e.g., LPV821) by 2.5× bandwidth per µA, enabling faster settling in multiplexed sensor arrays. |
| −40°C to 125°C operation | Validated for automotive cabin modules and industrial motor controllers where ambient exceeds 85°C. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPV821DRXT | Lower supply current (650 nA) but reduced GBW (13 kHz); no shutdown pin; 5-pin SOT-23. | Better for nanoamp-bias pH sensors; unsuitable for >10 kHz signal paths or shutdown-controlled systems. | Select LPV821DRXT only when bandwidth <15 kHz and shutdown control is unnecessary. |
| OPA316IDBVR | Higher supply current (400 µA), higher GBW (10 MHz), no shutdown; 5-pin SOT-23. | Required for active filters or fast-settling ADC drivers; incompatible with multiday battery life targets. | Choose OPA316IDBVR when signal bandwidth exceeds 100 kHz and power budget allows >10× higher IDD. |
Compared with LPV821DRXT and OPA316IDBVR, TLV2450AID uniquely balances 220 kHz bandwidth, 23 µA supply current, and integrated shutdown in a 6-pin SOT-23 - making it the only option for battery-powered precision amplifiers needing both speed and ultra-low quiescent power with controllable enable.

FAQ
What is the operating temperature range for TLV2450AID?
The TLV2450AID is rated for operation from −40°C to 125°C, validated across the full range per its I-suffix qualification. This makes TLV2450AID suitable for under-hood automotive modules, industrial motor drives, and outdoor environmental sensors where ambient extremes exceed commercial-grade limits.
Does TLV2450AID support true rail-to-rail input and output?
Yes, TLV2450AID provides 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 capability is confirmed in the datasheet's Electrical Characteristics tables and Typical Characteristics curves (Figures 1–2, 11–14), ensuring full utilization of 3 V and 5 V supply rails.
How does the shutdown function work on TLV2450AID?
The TLV2450AID shutdown pin (Pin 5) is active-low: driving it to GND places the output in high-impedance state and reduces supply current to 16 nA/channel. Pulling SHDN to VDD enables normal operation. Logic thresholds are VIL ≤ 0.5 V (VDD = 3 V) and ≤ 0.8 V (VDD = 5 V), per the Recommended Operating Conditions table.
What package type is used for TLV2450AID?
TLV2450AID uses the 6-pin SOT-23 (DBV) package, measuring 2.9 mm × 1.6 mm × 1.1 mm. This is explicitly confirmed in the "TLV2450 and TLV2451 AVAILABLE OPTIONS" table and the "TLV245x PACKAGE PINOUTS" diagram showing the 6-pin DBV top view with labeled pins OUT, IN−, IN+, GND, SHDN, and VDD+.
Can TLV2450AID drive capacitive loads?
TLV2450AID maintains stability into ≥1000 pF capacitive loads, demonstrated by 56° phase margin in Figure 24 (Phase Margin vs Load Capacitance). For loads >100 pF, a series resistor (10–50 Ω) between amplifier output and capacitance is recommended to prevent peaking, as noted in TI's application guidance for rail-to-rail op-amps.
