Product details
Overview
TLV2450IDBVT from Texas Instruments is a single-channel rail-to-rail input/output operational amplifier optimized for ultralow-power, low-voltage portable applications. It delivers 220 kHz gain-bandwidth, ±10 mA output drive, 23 µA supply current per channel, and operates from 2.7 V to 6 V. Its shutdown function reduces quiescent current to 16 nA/channel, making it ideal for battery-powered patient monitoring and data acquisition circuits.
For engineers reviewing the TLV2450IDBVT datasheet, TLV2450IDBVT pinout, TLV2450IDBVT application, or TLV2450IDBVT equivalent, key selection criteria include rail-to-rail I/O swing at 3 V supply, shutdown timing (836 ns turnoff), input offset voltage (20 µV typ), and SOT-23-6 package compatibility with high-density PCB layouts.
Technical Context
The TLV2450IDBVT implements 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 architecture supports stable unity-gain operation with 56° phase margin at 1 nF capacitive load and achieves 220 kHz gain-bandwidth product at 5 V supply.
Shutdown control is TTL/CMOS-compatible: logic-low (≤0.5 V at 3 V supply or ≤0.8 V at 5 V) disables the amplifier and places the output in high-impedance state, while logic-high enables normal operation. The device is fully specified across −40°C to +125°C and supports single-supply operation down to 2.7 V.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPV821DBVR | Lower supply current (650 nA), lower GBW (10 kHz), no shutdown pin, SOT-23-5 package. | Optimized for nano-power sensor wake-up circuits-not suitable for active signal conditioning requiring >100 kHz bandwidth. | Select when ultra-deep sleep dominates system power budget and bandwidth demand is <10 kHz. |
| OPA316IDBVR | Higher supply current (400 µA), higher GBW (10 MHz), rail-to-rail I/O, no shutdown, SOT-23-5 package. | Targeted at higher-speed precision applications (e.g., active filters, fast-settling ADC drivers) where power is secondary. | Select when bandwidth >1 MHz and settling time <1 µs are required, and shutdown is managed externally. |
Compared with LPV821DBVR and OPA316IDBVR, TLV2450IDBVT uniquely balances micropower operation (23 µA), usable bandwidth (220 kHz), and integrated shutdown in a 6-pin SOT-23-making it the only option among the three that supports both extended battery life and real-time analog processing in space-constrained portable designs.

FAQ
What is the operating temperature range for TLV2450IDBVT?
The TLV2450IDBVT is rated for operation from −40°C to +125°C, matching the "I" temperature suffix. This specification is validated across all electrical parameters in the datasheet, including input offset voltage, supply current, and gain-bandwidth product-making TLV2450IDBVT suitable for under-hood automotive modules and industrial field transmitters without thermal derating.
Does TLV2450IDBVT support true rail-to-rail input and output operation?
Yes, TLV2450IDBVT supports 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 at both 3 V and 5 V supplies, enabling full utilization of ADC reference voltages in low-voltage systems.
How does the shutdown function work on TLV2450IDBVT?
The TLV2450IDBVT shutdown pin (Pin 5) is active-low: applying ≤0.5 V (at 3 V supply) or ≤0.8 V (at 5 V supply) disables the amplifier, reducing supply current to 16 nA/channel and placing the output in high-impedance state. Turnoff time is 836 ns; turnon time is 59 µs-both measured at 50% control signal transition points.
What is the typical input offset voltage of TLV2450IDBVT and how stable is it over temperature?
The typical input offset voltage of TLV2450IDBVT is 20 µV at 25°C, with a maximum of 1300 µV over the full −40°C to +125°C range. Its temperature coefficient is 0.3 µV/°C, meaning drift contributes <30 µV over a 100°C span-critical for precision DC-coupled applications like thermopile amplification or strain gauge bridges.
Can TLV2450IDBVT drive a 10 kΩ load to the rails at 3 V supply?
Yes, TLV2450IDBVT can drive a 10 kΩ load to within 250 mV of each rail at 3 V supply while delivering ±2.5 mA. At 3 V, VOH = 2.85 V (min) and VOL = 0.16 V (max) under 500 µA load per the datasheet; extrapolation to 2.5 mA confirms rail proximity remains within spec-enabling direct interfacing with 12-bit SAR ADCs referenced to 3 V.
