Product details

Overview

TLV27L1IDBVTG4 from Texas Instruments is a single-channel micropower rail-to-rail output operational amplifier designed for ultra-low-power sensor signal conditioning and battery-powered instrumentation. It delivers 160 kHz gain-bandwidth, 0.1 V/μs slew rate, 7 μA supply current per channel, 89 nV/√Hz input voltage noise, and operates from 2.7 V to 16 V over −40°C to +125°C - enabling use in portable medical devices and industrial smoke detectors.

For engineers reviewing the TLV27L1IDBVTG4 datasheet, TLV27L1IDBVTG4 pinout, TLV27L1IDBVTG4 application, or TLV27L1IDBVTG4 equivalent, key selection criteria include its SOT-23-5 package, 1 pA input bias current, rail-to-rail output swing down to 2.7 V supply, and guaranteed performance across extended temperature range without external trimming.

Technical Context

The TLV27L1IDBVTG4 employs BiMOS input stage architecture to achieve 1 pA typical input bias current while maintaining rail-to-rail output swing via complementary MOS output transistors. Its 160 kHz unity-gain bandwidth is optimized for low-frequency precision sensing rather than high-speed signal processing.

It supports single-supply operation from 2.7 V (±1.35 V dual) up to 16 V (±8 V dual), with input common-mode range extending from −0.2 V to VS+1.2 V and output swing within 50 mV of rails at ±5 V supply - making it suitable for direct interfacing with ADCs and microcontroller analog inputs in energy-constrained systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.7 V to 16 V - enables operation from two alkaline cells (3 V) or Li-ion (up to 4.2 V) without regulation
Quiescent Current	7 μA per channel - allows continuous monitoring in battery-powered systems for >10 years on CR2032
Gain-Bandwidth Product	160 kHz - sufficient for DC–100 Hz sensor amplification with stable unity-gain configuration
Input Bias Current	1 pA typical - minimizes voltage error in high-impedance pH or photodiode front-ends
Input Voltage Noise	89 nV/√Hz at 1 kHz - supports sub-mV-level signal amplification in low-frequency biosensors
Output Swing	Within 50 mV of rails at ±5 V - preserves dynamic range when driving 12-bit SAR ADCs directly
Operating Temperature	−40°C to +125°C - qualified for under-hood automotive and industrial process monitoring

Equivalent & Alternatives

The following parts are listed as comparable options for similar operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV2371IDBVR	Higher 20 μA I_Q, 3 MHz GBW, 1.2 V/μs slew rate, same SOT-23-5 package	Better for higher-frequency filtering but consumes nearly 3× more power	Select when bandwidth >1 MHz required and battery life is secondary to response time
OPA349AIDBVR	Lower 1 μA I_Q, narrower 70 kHz GBW, 0.07 V/μs slew rate, same temperature range	Optimized for ultra-low-power DC sensing only; insufficient for AC-coupled PIR signals	Select when only sub-100 Hz signals are processed and maximum battery longevity is critical

Compared with TLV2371IDBVR and OPA349AIDBVR, the TLV27L1IDBVTG4 uniquely balances 160 kHz bandwidth, 7 μA quiescent current, and rail-to-rail output in a single SOT-23-5 package - making it the optimal choice for cost-sensitive, wide-temperature, medium-bandwidth sensor interfaces where power and precision must coexist.

FAQ

What is the maximum operating supply voltage for TLV27L1IDBVTG4?

The TLV27L1IDBVTG4 has an absolute maximum supply voltage of 16.5 V, with recommended operation from 2.7 V to 16 V. This allows direct use with two rechargeable lithium cells (up to 4.2 V each) or single 12-V industrial rails. Exceeding 16.5 V risks permanent damage per TI's Absolute Maximum Ratings table.

Does TLV27L1IDBVTG4 support rail-to-rail input capability?

No, the TLV27L1IDBVTG4 features rail-to-rail *output* only. Its input common-mode voltage range is specified from −0.2 V to VS+1.2 V, meaning it accepts inputs slightly beyond the negative rail but not fully to the positive rail. For true rail-to-rail input, consider alternatives like the TLV2461, though at higher quiescent current.

What is the input offset voltage specification for TLV27L1IDBVTG4 over temperature?

The TLV27L1IDBVTG4 has a maximum input offset voltage of 7 mV across the full −40°C to +125°C range, with typical value of 0.5 mV at 25°C. Its offset voltage drift is 1.1 μV/°C, resulting in <0.15 mV total drift over the entire temperature span - critical for precision DC measurements in uncalibrated systems.

Can TLV27L1IDBVTG4 drive capacitive loads without instability?

The TLV27L1IDBVTG4 maintains stability with up to 50 pF capacitive load when configured as a unity-gain buffer, as confirmed by phase margin testing (62° at 25°C). For loads >50 pF, external isolation resistor (e.g., 10 Ω in series with output) is recommended to prevent peaking or oscillation in sensor interface applications.

Is TLV27L1IDBVTG4 RoHS-compliant and lead-free?

Yes, TLV27L1IDBVTG4 is RoHS-compliant with lead-free (Sn) termination and complies with JEDEC Level-1 moisture sensitivity standards. The "G4" suffix denotes green packaging per TI's material specifications, and the device uses NiPdAu or Sn lead finish depending on reel batch - both fully compliant with EU RoHS Directive 2011/65/EU.
