Product details
Overview
TLV2401IDBVRG4 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, supports supply voltages from 2.5 V to 16 V, and features an extended common-mode input range (–0.1 V to VCC + 5 V), making it ideal for Li-ion-powered sensor front-ends and ultra-low-power industrial monitoring systems.
For engineers reviewing the TLV2401IDBVRG4 datasheet, TLV2401IDBVRG4 pinout, TLV2401IDBVRG4 application, or TLV2401IDBVRG4 equivalent, key selection criteria include its sub-1-µA quiescent current, 5.5-kHz gain-bandwidth product, 390-µV typical input offset voltage, rail-to-rail I/O capability, and guaranteed operation across –40°C to 125°C industrial temperature range.
Technical Context
The TLV2401IDBVRG4 employs a hybrid PNP/NPN input stage enabling true rail-to-rail input operation and over-the-rail tolerance (up to VCC + 5 V) without phase inversion or damage. Its internal reverse-battery protection circuit limits supply current to <100 nA under –18 V reverse bias, eliminating need for external series diodes in battery-powered designs.
DC precision is maintained via low input bias current (100 pA typ. at 25°C), high CMRR (120 dB typ. at 25°C), and robust open-loop gain (130 V/mV min. at 2.7 V). The device operates stably with capacitive loads up to 100 pF and achieves 60° phase margin, supporting unity-gain follower and inverting configurations in low-noise signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 880 nA/channel - enables multi-year battery life in always-on IoT sensors and portable medical monitors. |
| Gain Bandwidth Product | 5.5 kHz - suitable for DC-coupled signal conditioning, thermistor amplification, and slow-varying sensor outputs. |
| Input Offset Voltage | 390 µV typ. - ensures <1 mV total error in 12-bit ADC front-ends with gain ≤10. |
| Rail-to-Rail I/O | Input: –0.1 V to VCC + 5 V; Output: within 180 mV of rails at 50 µA load - maximizes dynamic range in single-supply systems. |
| Reverse Battery Protection | Withstands –18 V supply reversal with <100 nA leakage - eliminates external protection diode and associated voltage drop. |

FAQ
What is the maximum reverse supply voltage the TLV2401IDBVRG4 can withstand?
The TLV2401IDBVRG4 is rated for reverse battery protection up to –18 V. Under this condition, with inputs grounded and outputs open, supply current remains below 100 nA at 25°C. This specification is validated per TI's SLOS244B datasheet and eliminates need for external reverse-polarity protection diodes in TLV2401IDBVRG4-based designs.
Does the TLV2401IDBVRG4 support rail-to-rail input beyond the positive supply rail?
Yes - the TLV2401IDBVRG4 accepts common-mode input voltages from –0.1 V to VCC + 5 V. This over-the-rail capability is enabled by its dual-input-stage architecture (PNP + NPN followers) and is fully specified across the industrial temperature range (–40°C to 125°C), as confirmed in the "Common-Mode Input Range" section of the TLV2401IDBVRG4 datasheet.
What is the typical input offset voltage of the TLV2401IDBVRG4 at 25°C?
The TLV2401IDBVRG4 has a typical input offset voltage of 390 µV at 25°C, with a maximum of 1500 µV across the full industrial temperature range (–40°C to 125°C). This value is measured under standard test conditions (VO = VCC/2, VIC = VCC/2) and directly impacts DC accuracy in precision amplification stages using TLV2401IDBVRG4.
Can the TLV2401IDBVRG4 drive capacitive loads, and if so, up to what value?
Yes - the TLV2401IDBVRG4 is stable with capacitive loads up to 100 pF, achieving 60° phase margin and 15 dB gain margin under standard test conditions (RL = 500 kΩ, CL = 100 pF). This is verified in Figure 24 and Figure 25 of the TLV2401IDBVRG4 datasheet and supports direct interface to ADC input capacitors and long PCB traces without external isolation resistors.
What package type is used for the TLV2401IDBVRG4, and is it RoHS-compliant?
The TLV2401IDBVRG4 is supplied in a 5-pin SOT-23 (DBV) package with G4 suffix indicating green (lead-free/RoHS-compliant) packaging. The device meets JEDEC J-STD-020 moisture sensitivity level 1 and is rated for peak reflow temperature of 260°C, as documented in the TLV2401IDBVRG4 packaging information table.
