Product details
Overview
TLV2451IDBVT 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 key role is precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2451IDBVT datasheet, TLV2451IDBVT pinout, TLV2451IDBVT application, or TLV2451IDBVT equivalent, this page provides verified electrical specifications, SOT-23-5 package layout, rail-to-rail dynamic range implications, shutdown behavior, and direct alternatives for low-power analog signal chain design.
Technical Context
The TLV2451IDBVT uses CMOS input stage architecture enabling 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 220 kHz gain-bandwidth product and 0.11 V/µs slew rate support stable unity-gain buffering and low-frequency amplification without phase reversal.
It features no internal shutdown terminal - unlike TLV2450/3/5 - and is specified across −40°C to +125°C industrial temperature range. Input offset voltage is 20 µV (typ), with PSRR of 106 dB and CMRR of 76–89 dB, making it suitable for high-precision DC-coupled sensing where supply noise rejection and common-mode immunity are critical.
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) systems without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - enables stable DC to ~100 kHz signal amplification with ≤1% gain error in unity-gain configuration. |
| Supply Current per Channel | 23 µA - allows >1-year battery life in continuous-sensing nodes powered by CR2032 (225 mAh). |
| Output Drive Capability | ±10 mA - drives 10 kΩ loads to rail while maintaining linearity; sufficient for driving ADC reference buffers or low-R sensor interfaces. |
| Input Offset Voltage | 20 µV (typ) - contributes <0.2 mV error in 1 V full-scale 12-bit system, enabling sub-LSB accuracy without trimming. |
| Rail-to-Rail I/O | Yes - maximizes dynamic range in 3.3 V or lower supply systems, preserving >95% of available voltage headroom. |
| PSRR | 106 dB - suppresses supply ripple by >200,000×, critical for clean analog front-ends sharing noisy digital rails. |
Pinout & Package
SOT-23-5 (DBV) package: 5-pin, ultra-small surface-mount outline measuring 2.9 mm × 1.6 mm × 1.1 mm, optimized for high-density PCB layouts in portable equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ±10 mA into resistive loads. |
| 2 (IN−) | Inverting Input | High-impedance CMOS node; accepts input common-mode voltages from 0 V to VDD. |
| 3 (IN+) | Non-Inverting Input | High-impedance CMOS node; matched bias current (<5 nA) minimizes offset drift in high-Z sensor interfaces. |
| 4 (GND) | Analog Ground Reference | Return path for input common-mode and output current; must be low-impedance and separated from digital ground. |
| 5 (VDD+) | Positive Supply Rail | Accepts 2.7–6 V; internal regulation ensures stable operation across battery discharge profile. |

FAQ
What is the operating temperature range for TLV2451IDBVT?
The TLV2451IDBVT is rated for operation from −40°C to +125°C, as indicated by the "I" suffix in its part number. This industrial-grade temperature range is validated per TI's SLOS218F datasheet and supports deployment in harsh environments such as automotive cabins, industrial control enclosures, and outdoor medical devices without derating.
Does TLV2451IDBVT include a shutdown pin?
No, TLV2451IDBVT does not include a shutdown pin. The TLV2450, TLV2453, and TLV2455 variants feature a dedicated SHDN terminal, but TLV2451 - including TLV2451IDBVT - is a non-shutdown single-channel device. Its 23 µA quiescent current is fixed and cannot be reduced via external control.
What is the maximum output current capability of TLV2451IDBVT?
TLV2451IDBVT delivers ±10 mA output current into resistive loads at VDD = 5 V, as specified in the Electrical Characteristics table (page 7 of SLOS218F). At 3 V supply, output drive remains ≥±4 mA. This enables direct interface to 10 kΩ ADC reference inputs or low-R sensor excitation networks without external buffers.
Can TLV2451IDBVT operate from a single 3.3 V supply?
Yes, TLV2451IDBVT is fully specified for single-supply operation from 2.7 V to 6 V, including 3.3 V. Its rail-to-rail input and output stages allow full-swing signal handling - e.g., amplifying a 0–3.3 V sensor output to drive a 3.3 V ADC - with no headroom loss due to input/output voltage limitations.
What package type is used for TLV2451IDBVT?
TLV2451IDBVT uses the 5-pin SOT-23 (DBV) package, measuring 2.9 mm × 1.6 mm × 1.1 mm. This ultrasmall outline is tape-and-reel compatible and optimized for space-constrained portable electronics, as confirmed in TI's Family Package Table and Pinouts section (pages 3–4 of SLOS218F).
