Product details
Overview
TLV379IDBVR from Texas Instruments is a single-channel, micropower, rail-to-rail input/output operational amplifier optimized for ultra-low-power battery-operated systems. It delivers 4 µA typical quiescent current, 0.8 mV typical input offset voltage, and 90 kHz gain-bandwidth product across 1.8 V to 5.5 V supply, enabling precision signal conditioning in power-bank voltage monitoring and portable medical sensor front-ends.
For engineers reviewing the TLV379IDBVR datasheet, TLV379IDBVR pinout, TLV379IDBVR application, or TLV379IDBVR equivalent, this page provides verified package mapping (SOT-23-5), confirmed rail-to-rail I/O behavior, validated thermal performance (RθJA = 220.8°C/W), and real-world design guidance for capacitive load stability and low-noise biasing.
Technical Context
The TLV379IDBVR employs a complementary differential input stage to achieve rail-to-rail common-mode input range extending 100 mV beyond both supply rails, with CMRR specified from V– to (V+ – 1 V). Its class AB output stage enables full rail-to-rail output swing-typically within 25 mV of either rail at 5 kΩ load-while maintaining unity-gain stability without external compensation.
Designed for single-supply operation down to 1.8 V, the device features 5 pA typical input bias current, 83 nV/√Hz input voltage noise density at 1 kHz, and robust ESD protection (±2000 V HBM, ±1000 V CDM), making it suitable for high-impedance sensor interfaces in harsh industrial environments.

FAQ
What is the maximum capacitive load the TLV379IDBVR can drive without instability?
The TLV379IDBVR exhibits overshoot in unity-gain buffer configurations with capacitive loads exceeding 30 pF. For stable operation, insert a 10–20 Ω series resistor between the OUT pin and the load capacitance. This maintains DC accuracy while suppressing ringing-verified in TI's SBOS785B datasheet Figure 11. TLV379IDBVR does not require external compensation under this condition.
Does the TLV379IDBVR support dual-supply operation?
Yes, TLV379IDBVR operates from dual supplies ranging from ±0.9 V to ±2.75 V, as specified in Section 7.3 of the SBOS785B datasheet. The device maintains rail-to-rail input and output swing relative to its local V+ and V– pins, enabling symmetric signal handling in legacy analog systems without redesigning power architecture.
How does the TLV379IDBVR's input offset voltage drift with temperature?
TLV379IDBVR has a maximum input offset voltage drift of 3 µV/°C over –40°C to +125°C, per Section 7.7 of the datasheet. At 125°C, total drift from 25°C is ≤300 µV-well within the 2.5 mV max VOS specification. This stability makes TLV379IDBVR suitable for temperature-varying environments like automotive cabin sensors.
Can the TLV379IDBVR be used in a window comparator configuration?
Yes, TLV379IDBVR is commonly deployed in window comparators, as demonstrated in TI's Figure 19 using the dual-channel TLV2379. For single-channel use, two TLV379IDBVR units can implement independent upper/lower threshold detection. Its 90 kHz GBW and rail-to-rail output ensure fast response to input transients without latch-up.
What bypass capacitor value is recommended for TLV379IDBVR's power pins?
A 0.1-µF ceramic capacitor placed within 2 mm of the V+ and V– pins is mandatory for stable operation, per Section 10 and Figure 21 of the SBOS785B datasheet. This low-ESR capacitor suppresses supply noise coupling and prevents oscillation-especially critical given TLV379IDBVR's 4 µA quiescent current and high input impedance.
