Product details
Overview
TLV2451CDBVRG4 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 - enabling high dynamic range in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2451CDBVRG4 datasheet, TLV2451CDBVRG4 pinout, TLV2451CDBVRG4 application, or TLV2451CDBVRG4 equivalent, key selection criteria include its 5-pin SOT-23 package, shutdown-incompatible design (no SHDN pin), rail-to-rail I/O swing within 250 mV of rails at 2.5 mA load, and guaranteed operation across 0°C to 70°C.
Technical Context
The TLV2451CDBVRG4 employs a CMOS input stage with rail-to-rail common-mode input voltage range (0 V to VDD) and rail-to-rail output swing capability. Its internal architecture supports stable unity-gain operation with 56° phase margin into 1000 pF capacitive loads and achieves 220 kHz gain-bandwidth product at 5 V supply.
It features 106 dB power supply rejection ratio (PSRR), 89 dB common-mode rejection ratio (CMRR), and 20 µV typical input offset voltage - all specified over the full C-suffix temperature range (0°C to 70°C) and validated at both 3 V and 5 V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports direct connection to single-cell Li-ion (3.0–3.7 V) or two-cell alkaline (3.0–3.2 V) batteries without regulation. |
| Gain-Bandwidth Product | 220 kHz - enables stable amplification of DC to ~100 kHz signals in sensor conditioning and low-speed data acquisition. |
| Supply Current per Channel | 23 µA - allows >1-year battery life in always-on wearable health monitors drawing <10 µA average system current. |
| Output Drive Capability | ±10 mA - drives 10 kΩ loads to rail while maintaining linearity, sufficient for driving ADC reference buffers or LED bias circuits. |
| Input Offset Voltage | 20 µV (typ) - minimizes DC error in precision thermistor or strain gauge amplifiers requiring <100 µV total offset budget. |
| Rail-to-Rail I/O | Swings within 250 mV of each rail at 2.5 mA load - maximizes usable signal swing in 3.3 V or lower supply systems. |
| PSRR / CMRR | 106 dB / 89 dB - rejects supply noise and common-mode interference in noisy industrial or automotive environments. |
Pinout & Package
TLV2451CDBVRG4 is housed in a 5-pin SOT-23 (DBV) package with exposed pad for thermal enhancement. Pin 1 is marked by a molded dot or beveled edge; the device has no shutdown functionality.
| 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 common-mode voltages from 0 V to VDD. |
| 3 (IN+) | Non-inverting input | High-impedance CMOS node; matched bias current to IN− for minimal offset drift. |
| 4 (GND) | Analog ground reference | Return path for input bias currents and output load current; must be low-impedance for PSRR integrity. |
| 5 (VDD+) | Positive supply | Accepts 2.7–6 V; internal regulation ensures stable operation across battery discharge profile. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of supply voltage headroom in 3.3 V or lower systems, increasing SNR in ADC interfaces. |
| 23 µA supply current per channel | Reduces quiescent power to 75 µW at 3.3 V - critical for energy harvesting and coin-cell-powered IoT nodes. |
| 220 kHz gain-bandwidth product | Supports closed-loop gains up to 22 at 10 kHz, suitable for anti-aliasing filters and sensor signal conditioning. |
| 106 dB PSRR | Maintains accuracy when powered from noisy switch-mode supplies or shared LDO rails in multi-rail systems. |
| 20 µV typical input offset | Eliminates need for external offset trimming in medical-grade ECG front-ends and precision weigh-scale amplifiers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA316IDBVR | Higher 10 MHz GBW, 100 µA supply current, same 5-pin SOT-23 package. | Targets higher-speed sensor interfaces (e.g., ultrasound front-ends); not suitable for <50 µA ultra-low-power designs. | Select when bandwidth >1 MHz is required and 4× higher supply current is acceptable. |
| MCP6001UT-E/OT | Lower 1 MHz GBW, 1 µA supply current, rail-to-rail I/O, same SOT-23-5 footprint. | Optimized for sub-µA standby systems; insufficient drive strength (±1.7 mA) for driving 10 kΩ ADC references. | Select only for nano-power applications where output drive and bandwidth are secondary to quiescent current. |
Compared with OPA316IDBVR and MCP6001UT-E/OT, TLV2451CDBVRG4 uniquely balances 220 kHz bandwidth, ±10 mA drive, and 23 µA supply current in a 5-pin SOT-23 - making it optimal for mid-speed, battery-critical medical and industrial sensing where both precision and power efficiency are non-negotiable.

Does TLV2451CDBVRG4 include a shutdown pin?
No, TLV2451CDBVRG4 does not include a shutdown pin. The TLV2451 variant is defined in the Family Package Table as having "-" under the Shutdown column, and its 5-pin SOT-23 (DBV) pinout diagram shows only OUT, IN−, IN+, GND, and VDD+ - with no SHDN terminal. Only TLV2450, TLV2453, and TLV2455 offer shutdown functionality.
What is the maximum output current capability of TLV2451CDBVRG4?
The TLV2451CDBVRG4 provides ±10 mA output drive capability, as specified in the "Electrical Characteristics" table at VDD = 5 V. This value is measured under VO = 0.5 V from rail conditions and is valid across the full operating temperature range (0°C to 70°C), enabling direct interface with moderate-load circuits like ADC reference buffers or LED drivers.
Is TLV2451CDBVRG4 compatible with 3.3 V supply systems?
Yes, TLV2451CDBVRG4 is fully compatible with 3.3 V supply systems. Its VDD range is 2.7 V to 6 V, and all key parameters - including 220 kHz gain-bandwidth, 23 µA supply current, and rail-to-rail I/O - are characterized and guaranteed at 3 V. The device maintains 250 mV rail margin at 2.5 mA load, ensuring robust operation across the entire 3.3 V nominal range.
What package type is used for TLV2451CDBVRG4?
TLV2451CDBVRG4 uses the 5-pin SOT-23 (DBV) package, as indicated by the "DBV" suffix in the part number and confirmed in the "TLV2450 and TLV2451 AVAILABLE OPTIONS" table. The DBV package is tape-and-reel compatible (R suffix), and the pinout matches the standard 5-pin SOT-23 layout: OUT, IN−, IN+, GND, VDD+.
