Product details
Overview
TLV27L2IDR from Texas Instruments is a dual-channel micropower rail-to-rail output operational amplifier designed for ultra-low-power signal conditioning in battery-operated systems. It delivers 160 kHz gain-bandwidth, 0.1 V/μs slew rate, 7 μA per channel quiescent current, and operates from 2.7 V to 16 V supply across −40°C to +125°C. It serves as a precision sensor front-end in portable medical devices and low-power security detection systems.
For engineers reviewing the TLV27L2IDR datasheet, TLV27L2IDR pinout, TLV27L2IDR application, or TLV27L2IDR equivalent, key selection criteria include its industrial-grade temperature range, rail-to-rail output swing down to 2.7 V, input bias current of 1 pA, and SOIC-8 packaging with verified thermal performance up to 125°C ambient.
Technical Context
The TLV27L2IDR employs BiMOS input stage architecture enabling 1 pA input bias current and rail-to-rail output swing within ±120 mV of supply rails at 5 V. Its 160 kHz unity-gain bandwidth and 0.1 V/μs slew rate support stable DC-coupled amplification and low-frequency AC signal conditioning without phase margin degradation.
It features a common-mode input voltage range extending from −0.2 V to VS+1.2 V, allowing operation with inputs near ground or above VDD-critical for single-supply sensor interfaces. Input offset voltage is specified at 5 mV max (full temperature range), and PSRR reaches 70 dB over −40°C to +125°C.
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 min) and dual-rechargeable (±1.35 V) configurations |
| Quiescent Current | 7 μA per channel - enables >10-year battery life in smoke detectors with periodic wake-up sampling |
| Gain Bandwidth Product | 160 kHz - sufficient for ECG front-end filtering and power monitoring loop response |
| Slew Rate | 0.1 V/μs - ensures <44 μs settling to 0.1% for 1 V step, suitable for slow-varying sensor outputs |
| Input Bias Current | 1 pA - minimizes voltage error in high-impedance pH or photodiode transimpedance stages |
| Output Swing | Within 120 mV of rails at VS = 5 V - maximizes dynamic range in 3.3 V or 5 V microcontroller ADC interfaces |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive power monitoring and industrial field sensors |
Pinout & Package
TLV27L2IDR is housed in an 8-pin SOIC (D) package with standard JEDEC MS-012AC footprint (5.3 mm × 6.2 mm, 1.75 mm height). Thermal resistance θJA = 176°C/W enables 370 mW power dissipation at 85°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT (Channel 1) | Amplified output node; rail-to-rail swing supports full-scale ADC utilization |
| 2 | IN− (Channel 1) | Inverting input; high-impedance BiMOS node enables precision current sensing |
| 3 | IN+ (Channel 1) | Non-inverting input; accepts signals from −0.2 V to VS+1.2 V |
| 4 | GND | Analog ground reference; requires dedicated low-inductance plane per layout guidelines |
| 5 | VDD | Positive supply; decoupling with 0.1 μF ceramic capacitor mandatory at pin |
| 6 | IN− (Channel 2) | Second inverting input; independent bias path avoids crosstalk above −40 dB at 1 kHz |
| 7 | IN+ (Channel 2) | Second non-inverting input; matched offset and CMRR to Channel 1 |
| 8 | OUT (Channel 2) | Second rail-to-rail output; enables dual-sensor differential measurement |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers usable output swing within 120 mV of supply rails at 5 V, preserving ADC resolution in low-voltage systems |
| 1 pA input bias current | Reduces voltage error below 1 mV in 1 MΩ source impedance applications like thermistor or RTD interfaces |
| 160 kHz bandwidth at 7 μA | Enables stable closed-loop gain ≥100 while consuming less than 14 μA total for dual-channel operation |
| −40°C to +125°C operation | Validated performance across full industrial temperature range without derating or external compensation |
| SOIC-8 packaging | Compatible with standard automated assembly lines and legacy PCB footprints used for TLC27L2 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2382IDR | Same 7 μA IQ, but lower 86 dB CMRR and no rail-to-rail output (swing limited to VS−1.5 V) | Less suitable for single-supply sensor interfaces requiring full dynamic range | Select TLV2382IDR only when CMRR >90 dB is not required and output swing margin is available |
| TLC27L2CDR | Higher 17 μA IQ, 10 mV max VIO, and narrower 85 kHz GBW; lacks rail-to-rail output | Legacy drop-in replacement where power budget allows and rail-to-rail swing is unnecessary | Choose TLC27L2CDR only for cost-sensitive designs where existing PCB layout must be retained |
Compared with TLV2382IDR and TLC27L2CDR, TLV27L2IDR uniquely combines rail-to-rail output, 1 pA input bias, and industrial temperature range in SOIC-8-enabling higher-accuracy, longer-life designs in space-constrained battery systems.

FAQ
What is the maximum supply voltage for TLV27L2IDR?
The absolute maximum supply voltage for TLV27L2IDR 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 maintains rail-to-rail output swing and 160 kHz bandwidth, making it suitable for ±8 V dual-supply or 16 V single-supply industrial applications.
Does TLV27L2IDR support rail-to-rail input?
No, TLV27L2IDR does not support rail-to-rail input. Its common-mode input voltage range is specified from −0.2 V to VS−1.2 V, meaning the input cannot exceed VS−1.2 V. However, the output is rail-to-rail, swinging within 120 mV of both supply rails at 5 V. This makes TLV27L2IDR ideal for output-stage buffering but requires input signal conditioning if sources approach VDD.
What is the input offset voltage specification for TLV27L2IDR over temperature?
The input offset voltage for TLV27L2IDR is guaranteed ≤7 mV across the full −40°C to +125°C operating range, with a typical value of 0.5 mV at 25°C. The offset voltage drift is 1.1 μV/°C, resulting in <0.1 mV additional drift over a 100°C span-critical for precision DC measurements in industrial environments where TLV27L2IDR is deployed.
Can TLV27L2IDR drive capacitive loads directly?
TLV27L2IDR can drive up to 50 pF load capacitance while maintaining ≥62° phase margin, as confirmed in Figure 16 of the datasheet. For larger capacitive loads (e.g., >100 pF), external isolation resistance (≥100 Ω) is required between output and load to prevent instability. This limitation is relevant when interfacing TLV27L2IDR with long PCB traces or ADC input capacitors.
Is TLV27L2IDR pin-compatible with TLC27L2?
Yes, TLV27L2IDR is pin-compatible with TLC27L2 in the SOIC-8 (D) package, sharing identical pinout: Pin 1 (OUT1), Pin 2 (IN−1), Pin 3 (IN+1), Pin 4 (GND), Pin 5 (VDD), Pin 6 (IN−2), Pin 7 (IN+2), Pin 8 (OUT2). This allows direct PCB-level replacement, though TLV27L2IDR offers superior rail-to-rail output, lower IQ (7 μA vs 17 μA), and wider supply range (2.7 V min vs 4 V min).
