Product details
Overview
TLV27L2ID from Texas Instruments is a dual-channel, micropower rail-to-rail output operational amplifier optimized for industrial-temperature operation (−40°C to 125°C) in SOIC-8 packaging. It delivers 160 kHz gain-bandwidth, 0.1 V/μs slew rate, 7 μA per-channel quiescent current, 5 mV max input offset voltage, and operates from 2.7 V to 16 V single supply - enabling use in battery-powered smoke detectors and portable medical sensors where low power and wide supply range are critical.
For engineers reviewing the TLV27L2ID datasheet, TLV27L2ID pinout, TLV27L2ID application, or TLV27L2ID equivalent, this page provides verified electrical specifications, SOIC-8 terminal mapping, industrial-grade thermal performance data, and validated alternative options for low-power analog signal conditioning in constrained environments.
Technical Context
The TLV27L2ID employs BiMOS input stage architecture to achieve 1 pA typical input bias current and rail-to-rail output swing within 50 mV of each rail at ±5 V supply. Its 160 kHz unity-gain bandwidth is maintained across the full −40°C to 125°C temperature range with only 7 μA per channel supply current, making it suitable for precision DC-coupled sensing where thermal drift and power budget are tightly coupled.
Designed as a direct upgrade path from the TLC27L2, the TLV27L2ID retains identical SOIC-8 pinout and offset voltage specification (5 mV max), while improving bandwidth by >85% and reducing quiescent current by ~59% versus the legacy part - without requiring PCB layout changes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V single supply - supports operation from two 1.35-V rechargeable cells up to ±8-V dual rails. |
| Quiescent Current (per channel) | 7 μA typical at 2.7 V - enables multi-year battery life in always-on smoke detection circuits. |
| Gain-Bandwidth Product | 160 kHz typical - sufficient for anti-aliasing filtering and sensor signal amplification below 100 kHz. |
| Slew Rate | 0.1 V/μs typical - ensures stable step response for slow-varying industrial process signals. |
| Input Offset Voltage | 5 mV maximum - maintains <0.5% error in 1-V full-scale bridge sensor interfaces. |
| Rail-to-Rail Output | Swings within 50 mV of VDD/GND at ±5 V - maximizes dynamic range in low-voltage data acquisition systems. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive monitoring and industrial control cabinet deployment. |
Pinout & Package
TLV27L2ID is housed in an 8-pin SOIC (D) package with standard industry footprint (5.3 mm × 6.2 mm, 1.75 mm height). Pin 1 is marked via notch or bevel on the package top edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output channel A - drives external load or next-stage input with rail-to-rail swing. |
| 2 | IN− A | Inverting input for channel A - high-impedance node (1 pA bias) for feedback network connection. |
| 3 | IN+ A | Non-inverting input for channel A - accepts low-level sensor signals with minimal loading error. |
| 4 | GND | Analog ground reference - must connect to low-noise system ground plane with minimal trace inductance. |
| 5 | VDD | Positive supply rail - requires local 0.1-μF ceramic + 6.8-μF tantalum decoupling per TI layout guidelines. |
| 6 | OUT B | Inverting amplifier output channel B - independent output for dual-sensor conditioning or differential drive. |
| 7 | IN− B | Inverting input for channel B - electrically isolated from channel A; supports separate feedback paths. |
| 8 | IN+ B | Non-inverting input for channel B - enables simultaneous processing of two analog channels without crosstalk. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower Operation | 7 μA per channel enables >10-year battery life in 2xAA-powered security sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2382IDR | Lower 10 μA IQ, 160 kHz GBW, but 4.5 mV VIO and −0.2 to VS−0.2 VICR - no rail-to-rail input. | Preferred for ultra-low-power battery systems where input common-mode range is not constrained near rails. | Select TLV2382IDR when input signal stays ≥0.2 V above GND; retain TLV27L2ID for true rail-to-rail input capability. |
| TLC27L2IDR | Higher 17 μA IQ, 85 kHz GBW, 10 mV VIO, same SOIC-8 pinout and −40°C to 125°C rating. | Legacy option for cost-sensitive designs where bandwidth and power savings are secondary to procurement continuity. | Choose TLC27L2IDR only if existing design validation exists; TLV27L2ID offers superior performance with identical footprint. |
Compared with TLV2382IDR and TLC27L2IDR, the TLV27L2ID uniquely combines rail-to-rail input/output, 160 kHz bandwidth, and 7 μA quiescent current in a single industrial-grade SOIC-8 device - enabling higher accuracy and longer battery life without layout changes.

FAQ
What is the maximum supply voltage for TLV27L2ID?
The absolute maximum supply voltage for TLV27L2ID is 16.5 V, with recommended operating range from 2.7 V to 16 V single supply. Exceeding 16.5 V risks permanent damage per TI's Absolute Maximum Ratings table. At 16 V, the device maintains full rail-to-rail output swing and specified 160 kHz bandwidth across −40°C to 125°C.
Does TLV27L2ID support rail-to-rail input?
No, TLV27L2ID features rail-to-rail *output* only. Its input common-mode voltage range is specified as −0.2 V to VS−1.2 V, meaning it cannot accept signals within 1.2 V of the positive rail. This is confirmed in the "Recommended Operating Conditions" table on page 3 of the SLOS378B datasheet. For true rail-to-rail input, consider TLV2382IDR or OPAx347.
What is the input bias current of TLV27L2ID at 125°C?
At 125°C, the input bias current of TLV27L2ID is guaranteed ≤1000 pA (1 nA) per channel, per the "input characteristics" table on page 3 of the SLOS378B datasheet. The typical value remains ~1 pA at 25°C but increases with temperature due to BiMOS process characteristics - critical for high-impedance sensor interfaces in hot environments.
Is TLV27L2ID pin-compatible with TLC27L2IDR?
Yes, TLV27L2ID is fully pin-compatible with TLC27L2IDR in the SOIC-8 (D) package. Both share identical pin 1–8 assignments, mechanical footprint, and thermal pad configuration. TI explicitly states this compatibility in the "DESCRIPTION" section: "The TLV27Lx are good upgrades for the TLC27Lx family - offering more bandwidth at a lower quiescent current."
What decoupling capacitors are recommended for TLV27L2ID?
Texas Instruments recommends a 6.8-μF tantalum capacitor in parallel with a 0.1-μF ceramic capacitor on each supply terminal of TLV27L2ID. The 0.1-μF ceramic must be placed within 0.1 inches of the VDD and GND pins to minimize inductance, as stated in the "Circuit Layout Considerations" section (page 10). Shared tantalum capacitors are acceptable across multiple devices, but individual ceramic caps are mandatory per channel.
