Product details
Overview
TLV2450AIDR 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, 20 µV typical input offset voltage, and operates from 2.7 V to 6 V supply - enabling precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2450AIDR datasheet, TLV2450AIDR pinout, TLV2450AIDR application, or TLV2450AIDR equivalent, key selection criteria include shutdown current (16 nA/channel), rail-to-rail swing capability at 3 V, thermal stability across −40°C to 125°C, and SOT-23-6 package compatibility with high-density PCB layouts.
Technical Context
The TLV2450AIDR 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 shutdown logic asserts high-impedance output and reduces supply current to 16 nA/channel when SHDN is pulled low relative to GND.
Designed for single-supply operation, it maintains 106 dB PSRR and 76–89 dB CMRR over 2.7–6 V, with specified performance across −40°C to 125°C. The amplifier achieves 0.11 V/µs slew rate and 220 kHz GBW at 5 V, scaling to 200 kHz at 3 V per electrical characteristics tables.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports direct Li-ion (3.0–4.2 V) and dual-AA (3.0 V) battery operation without regulation. |
| Gain-Bandwidth Product | 220 kHz at 5 V - enables stable unity-gain buffer or low-frequency instrumentation amplifier configurations. |
| Input Offset Voltage | 300 µV max (25°C), 1300 µV max (−40°C to 125°C) - ensures sub-mV DC accuracy in sensor amplification paths. |
| Output Drive | ±10 mA - drives 500 Ω loads directly, eliminating need for external buffers in analog front-ends. |
| Shutdown Current | 16 nA/channel - extends battery life in intermittent-sampling systems like wearable ECG monitors. |
| PSRR | 106 dB - rejects ripple from switching regulators in mixed-signal embedded systems. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
TLV2450AIDR is housed in a 6-pin SOT-23 package (DBV), with 1.6 mm × 2.9 mm footprint and 0.95 mm height - optimized for space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; high-impedance during shutdown. |
| 2 (IN−) | Inverting input | CMOS input with 0.3–4.5 nA bias current; accepts signals from 0 V to VDD. |
| 3 (IN+) | Non-inverting input | CMOS input matching IN−; enables precision differential or single-ended sensing. |
| 4 (GND) | Analog ground reference | Return path for input common-mode and output load current; must be low-impedance. |
| 5 (SHDN) | Active-low shutdown control | Pull ≤0.5 V (at 3 V VDD) to enter ultra-low-power mode; open or high disables shutdown. |
| 6 (VDD+) | Positive supply | Accepts 2.7–6 V; powers amplifier core and shutdown logic; bypass capacitor required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3 V systems - e.g., 0–3 V ADC input scaling without level-shifting. |
| Ultralow shutdown current | 16 nA/channel allows >10-year battery life in wake-on-event sensor nodes with 10 µA average current budget. |
| 23 µA operating supply current | Permits integration of multiple channels in power-sensitive applications like multi-lead patient monitors. |
| Specified over extended temperature | Guaranteed performance from −40°C to 125°C eliminates derating concerns in automotive cabin or industrial motor-control enclosures. |
| High output drive | ±10 mA capability drives RC filters, multiplexers, or ADC input capacitance directly - reducing BOM count. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2451AIDR | No shutdown pin; 5-pin SOT-23; identical AC/DC specs except SHDN omission. | Used where continuous operation is required and board space is tighter (5-pin vs 6-pin). | Select TLV2451AIDR only if shutdown functionality is unnecessary and layout area is constrained. |
| OPA333AIDBVR | Zero-drift architecture; 17 µV max VIO (0.1 µV/°C drift); 65 µA IDD; no shutdown; SC70-5 package. | Better DC precision for weigh scales or precision references; higher supply current limits battery life. | Choose OPA333AIDBVR when offset drift dominates error budget, not power consumption. |
Compared with TLV2450AIDR, TLV2451AIDR removes shutdown capability to save one pin and PCB area but retains identical performance otherwise; OPA333AIDBVR trades 3× higher supply current for 6× lower offset drift - making TLV2450AIDR optimal for battery-powered, moderate-precision, rail-to-rail applications.

FAQ
What is the maximum supply voltage rating for TLV2450AIDR?
The absolute maximum supply voltage for TLV2450AIDR is 7 V, as specified in the Absolute Maximum Ratings table. Operation above 6 V violates recommended conditions and risks permanent damage. For reliable long-term use, maintain VDD between 2.7 V and 6 V per the Recommended Operating Conditions section of the datasheet. Exceeding 6 V may degrade parametric performance or accelerate device aging.
Does TLV2450AIDR support true rail-to-rail input and output operation?
Yes, TLV2450AIDR supports true 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 is confirmed in the device description and electrical characteristics tables. At 3 V supply, it delivers usable output from ~0.1 V to ~2.9 V with 2.5 mA load - critical for maximizing dynamic range in low-voltage systems.
How does the shutdown function operate on TLV2450AIDR?
The TLV2450AIDR shutdown pin (Pin 5) is active-low: pulling SHDN ≤0.5 V (at 3 V VDD) places the amplifier in ultralow-power mode with 16 nA/channel supply current and high-impedance output. When SHDN ≥2 V (at 3 V VDD), normal operation resumes. The shutdown transition times are 59 µs turn-on and 836 ns turn-off, as measured in the operating characteristics section.
What is the input offset voltage specification for TLV2450AIDR over temperature?
TLV2450AIDR has a maximum input offset voltage of 1300 µV across the full −40°C to 125°C operating range, with 300 µV typical at 25°C. Its temperature coefficient is 0.3 µV/°C, meaning offset drift contributes ≤0.3 µV per degree Celsius change. These values are explicitly listed in the Electrical Characteristics tables for TLV245xA grade devices under "Full range" conditions.
Is TLV2450AIDR pin-compatible with other members of the TLV245x family?
No, TLV2450AIDR is not pin-compatible with dual or quad variants (e.g., TLV2452, TLV2453) due to differing channel counts and pinouts. However, it shares the same 6-pin SOT-23 (DBV) footprint and pin assignment as TLV2450CDR and TLV2450IDR - only temperature grade and screening differ. Always verify pin mapping against the "TLV2450 DBV PACKAGE" diagram in the datasheet's Pinouts section.
