Product details
Overview
TLV2401CDBVR from Texas Instruments is a single-channel, rail-to-rail input/output micro-power operational amplifier with reverse battery protection up to 18 V. It delivers 880 nA supply current per channel, 5.5 kHz gain bandwidth, and operates from 2.5 V to 16 V - enabling ultra-low-power sensor signal conditioning in Li-ion–powered portable instrumentation.
For engineers reviewing the TLV2401CDBVR datasheet, TLV2401CDBVR pinout, TLV2401CDBVR application, or TLV2401CDBVR equivalent, key selection criteria include sub-1-µA quiescent current, ±100 mV beyond-rail input capability (–0.1 V to VCC + 5 V), rail-to-rail output swing, 390 µV typical input offset voltage, and SOT-23-5 packaging for space-constrained designs.
Technical Context
The TLV2401CDBVR uses a dual-differential-input architecture: a PNP pair handles common-mode inputs from –0.1 V to VCC – 0.8 V, while NPN emitter followers engage above VCC – 0.8 V to enable 5-V over-the-rail operation without damage. This design ensures stable biasing and gain continuity across the full extended input range.
Reverse battery protection is implemented via internal Schottky diode networks, limiting reverse supply current to <100 nA at 25°C when VCC = –18 V and inputs are grounded. The device maintains functional integrity under reverse polarity, eliminating need for external protection diodes in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply current | 880 nA/channel - enables >10-year battery life in always-on sensor nodes using CR2032 or coin cells. |
| Input offset voltage | 390 µV typical - supports high-precision DC-coupled amplification of µV-level thermocouple or strain gauge signals. |
| Gain bandwidth product | 5.5 kHz - suitable for low-frequency sensor interfaces (e.g., pH, gas, humidity) without stability risk. |
| Input common-mode range | –0.1 V to VCC + 5 V - allows direct connection to transducers biased above supply (e.g., 5-V reference sensors). |
| Rail-to-rail I/O | Output swings within 180 mV of rails at 50 µA load - maximizes dynamic range in single-supply 3.3-V or 5-V systems. |
| Reverse battery rating | 18 V reverse - protects against accidental battery reversal in automotive, industrial, or medical handheld devices. |
| Operating temperature | 0°C to 70°C (Commercial) - qualified for consumer electronics, smart home sensors, and portable test equipment. |
Pinout & Package
TLV2401CDBVR is housed in a 5-pin SOT-23 package (DBV), with exposed pad not electrically connected. The package supports reflow soldering and is rated for 260°C peak lead temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN–) | Inverting input | Differential node for feedback configuration; supports rail-to-rail common-mode input down to –0.1 V. |
| 2 (IN+) | Non-inverting input | Accepts signals up to VCC + 5 V without latch-up; critical for overvoltage-tolerant sensor front-ends. |
| 3 (GND) | Analog ground | Reference return for both input and output stages; must be tied to clean low-impedance ground plane. |
| 4 (VCC) | Positive supply | Supports 2.5–16 V operation; reverse-battery protected - sinks <100 nA at –18 V. |
| 5 (OUT) | Amplifier output | Rail-to-rail capable; drives ≥200 µA into resistive loads while maintaining linearity and low distortion. |
Key Features
| Feature | Design Value |
|---|---|
| Micro-power operation | 880 nA/channel enables multi-year operation on primary batteries without duty cycling. |
| Extended input voltage range | Inputs tolerate –0.1 V to VCC + 5 V - eliminates level-shifting for sensors referenced to external supplies. |
| Reverse battery protection | Withstands –18 V supply without external diodes - reduces BOM count and PCB area in battery-powered systems. |
| Rail-to-rail input/output | Full signal swing utilization in 2.5–16 V single-supply systems - improves SNR and ADC resolution usage. |
| Low input bias current | 100 pA typical at 25°C - preserves accuracy in megaohm-resistor networks (e.g., pH electrode buffers). |

FAQ
What is the maximum supply voltage for TLV2401CDBVR?
The absolute maximum supply voltage for TLV2401CDBVR is 17 V, with recommended operation from 2.5 V to 16 V. Exceeding 16 V may degrade long-term reliability, and operation below 2.5 V risks undefined behavior. Electrical characteristics are specified at 2.7 V, 5 V, and 15 V per the SLOS244B datasheet.
Does TLV2401CDBVR support rail-to-rail output swing under load?
Yes, TLV2401CDBVR delivers rail-to-rail output swing: at 50 µA load, VOL is ≤260 mV above GND and VOH is ≥VCC – 180 mV. At lighter loads (e.g., 2 µA), output swing tightens to within 90 mV of each rail - enabling full utilization of 3.3-V or 5-V ADC input ranges.
Can TLV2401CDBVR be used with input voltages above its positive supply rail?
Yes - TLV2401CDBVR accepts input voltages up to VCC + 5 V without damage or phase inversion. This is enabled by its dual-input-stage architecture (PNP + NPN followers). However, input bias current increases above VCC, so high-impedance sources should be verified for stability in this region.
What is the reverse battery protection behavior of TLV2401CDBVR?
When subjected to –18 V on VCC (inputs grounded, outputs open), TLV2401CDBVR draws <100 nA reverse supply current at 25°C. This is achieved via integrated Schottky diode clamping. The device remains undamaged and resumes normal operation upon polarity correction - eliminating need for external protection components.
Is TLV2401CDBVR compatible with standard SOT-23 reflow profiles?
Yes, TLV2401CDBVR (SOT-23-5, DBV package) is qualified for standard Pb-free reflow per JEDEC J-STD-020. Peak temperature is rated at 260°C for 10 seconds. The package has no exposed thermal pad, and board layout should follow TI's SOT-23 thermal guidelines to ensure reliable solder joint formation and long-term reliability of TLV2401CDBVR.
