Product details
Overview
TLV27L1CDBVR from Texas Instruments is a single-channel micropower rail-to-rail output operational amplifier in a 5-pin SOT-23 package, featuring 7 μA supply current per channel, 160 kHz gain-bandwidth product, 0.1 V/μs slew rate, and operation from 2.7 V to 16 V supply. It delivers precision signal conditioning in ultra-low-power portable medical sensors and smoke detectors.
For engineers reviewing the TLV27L1CDBVR datasheet, TLV27L1CDBVR pinout, TLV27L1CDBVR application, or TLV27L1CDBVR equivalent, this page provides verified electrical specifications, thermal performance data across −40°C to 125°C, SOT-23 layout guidance, and validated alternative options for low-quiescent-current op-amp selection.
Technical Context
The TLV27L1CDBVR uses BiMOS input stage architecture enabling 1 pA typical input bias current and rail-to-rail output swing within 50 mV of each rail at VS = 2.7 V. Its 160 kHz bandwidth and 0.1 V/μs slew rate support stable DC-coupled amplification and low-frequency sensor signal conditioning without phase margin degradation.
It operates over 2.7 V to 16 V single-supply (±1.35 V to ±8 V dual-supply), with input common-mode range extending from −0.2 V to VS + 1.2 V and guaranteed output swing to within 120 mV of rails under 500 μA load. Input offset voltage is specified at 5 mV max (25°C) and 7 mV max over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-cell Li-ion (3.0 V), two alkaline (3.0 V), or industrial 12 V rails without level-shifting. |
| Quiescent Current | 7 μA per channel - enables >10-year battery life in smoke detector standby mode with periodic sampling. |
| Gain-Bandwidth Product | 160 kHz - sufficient for ECG front-end filtering, power monitoring harmonics up to 50th order, and slow-loop control feedback. |
| Slew Rate | 0.1 V/μs - ensures <1% distortion on 1 VPP signals below 16 kHz, suitable for audio-grade sensor interfaces. |
| Input Bias Current | 1 pA typical - minimizes voltage error in high-impedance pH or ion-selective electrode circuits (>100 MΩ source). |
| Input Noise Voltage | 89 nV/√Hz at 1 kHz - enables resolution of sub-mV biopotential signals without dominant amplifier noise contribution. |
| Operating Temperature | 0°C to 70°C - commercial-grade qualification matching cost-sensitive portable medical and security system requirements. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9 mm × 1.6 mm × 1.15 mm body, surface-mount, lead-free (Sn), moisture sensitivity level 1, JEDEC-compliant tape-and-reel (3000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN− | Inverting input | High-impedance node accepting feedback network; requires shortest PCB trace to minimize stray capacitance-induced instability. |
| 2 - IN+ | Non-inverting input | Accepts sensor signal or reference; benefits from RC low-pass filter placement per TI application note Figure 26. |
| 3 - GND | Analog ground reference | Must connect directly to solid ground plane; avoid sharing with digital return paths to prevent noise coupling. |
| 4 - VDD | Positive supply | Requires local 0.1 μF ceramic + 6.8 μF tantalum decoupling; place capacitor ≤0.1 inch from pin per layout guidelines. |
| 5 - OUT | Amplified output | Rail-to-rail capable (within 50 mV at 2.7 V); drives 100 kΩ loads directly; avoid capacitive loads >50 pF without isolation resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range from 0 V to VS in single-supply systems, eliminating need for dual supplies in portable instrumentation. |
| 1 pA input bias current | Enables accurate amplification of nanoamp-level currents from photodiodes or electrochemical sensors without significant offset error. |
| 7 μA quiescent current | Reduces self-heating to <0.1°C rise at TA = 25°C, preserving offset stability in thermally sensitive measurement chains. |
| 160 kHz bandwidth at 7 μA | Provides 10× higher bandwidth than legacy TLC27Lx family at same current, enabling faster response in power-monitoring comparators. |
| −40°C to 125°C extended temp option | Industrial-grade variant TLV27L1IDBVR supports automotive cabin modules and industrial motor controllers beyond commercial range. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2381CDBVR | Same 5-pin SOT-23 package, 10 μA IQ, 160 kHz GBW, but lower 4.5 mV VIO max and −0.2 V to VS−0.2 V input range (not rail-to-rail input). | Better offset for precision DC measurement; unsuitable for VIC near VS where TLV27L1CDBVR maintains CMRR. | Select TLV2381CDBVR when input offset <4.5 mV is mandatory and input common-mode stays below VS−0.2 V. |
| TLC27L1CDBVR | Legacy BiFET op-amp in same SOT-23 package; 17 μA IQ, 85 kHz GBW, 10 mV VIO max, no rail-to-rail output. | Higher power, lower speed, larger offset - only viable if legacy design reuse mandates identical footprint without performance upgrade. | Choose TLC27L1CDBVR only for drop-in replacement in existing designs where 7 μA IQ and 160 kHz GBW are not required. |
Compared with TLV2381CDBVR and TLC27L1CDBVR, the TLV27L1CDBVR uniquely balances micropower operation (7 μA), rail-to-rail output, and 160 kHz bandwidth in SOT-23 - making it optimal for new designs requiring extended battery life without sacrificing signal fidelity or output headroom.

FAQ
What is the maximum supply voltage for TLV27L1CDBVR?
The absolute maximum supply voltage for TLV27L1CDBVR is 16.5 V, with recommended operating range from 2.7 V to 16 V. Exceeding 16.5 V risks permanent damage. At 16 V, the device supports ±8 V dual-supply configurations while maintaining rail-to-rail output swing and 7 μA quiescent current - critical for industrial power monitoring applications using standard 12 V rails.
Does TLV27L1CDBVR support rail-to-rail input?
No, TLV27L1CDBVR does not support rail-to-rail input. Its input common-mode voltage range is specified from −0.2 V to VS−1.2 V, meaning the inputs cannot operate within 1.2 V of the positive rail. However, its rail-to-rail output (within 50 mV of each rail at VS = 2.7 V) remains fully functional. For true rail-to-rail input capability, consider TI's TLV2461CDBVR as an alternative.
What is the thermal resistance θJA for TLV27L1CDBVR in SOT-23 package?
The junction-to-ambient thermal resistance (θJA) for TLV27L1CDBVR in SOT-23 (DBV) package is 324.1°C/W under JEDEC Low-K test board conditions. This value assumes no airflow and defines maximum power dissipation limits: at TA = 25°C, PDmax = 385 mW; at TA = 85°C, PDmax = 201 mW. Proper PCB copper pour under the exposed pad (if present) or thermal vias significantly improve real-world θJA.
Can TLV27L1CDBVR drive capacitive loads?
TLV27L1CDBVR is stable with capacitive loads ≤50 pF when driving 100 kΩ resistive loads, as confirmed by phase margin testing (62° at 25°C). For loads >50 pF, TI recommends adding a 10–100 Ω isolation resistor between OUT and the capacitor to maintain stability. This is essential in anti-aliasing filter or ADC driver applications where stray capacitance exceeds 50 pF.
Is TLV27L1CDBVR pin-compatible with TLC27L1CDBVR?
Yes, TLV27L1CDBVR is pin-compatible with TLC27L1CDBVR in the SOT-23-5 (DBV) package: both share identical pin 1 (IN−), pin 2 (IN+), pin 3 (GND), pin 4 (VDD), and pin 5 (OUT) assignments. This allows direct PCB replacement, delivering immediate improvements in bandwidth (+88%), quiescent current (−59%), and output swing capability without layout changes.
