Product details
Overview
TLV2382ID from Texas Instruments is a dual-channel micropower rail-to-rail input/output operational amplifier in SOIC-8 package, delivering 160 kHz gain-bandwidth, 7 µA per-channel supply current, and ±0.2 V input common-mode range beyond rails at 2.7–16 V supply. It enables precision low-power signal conditioning in portable medical sensors and smoke detectors.
For engineers reviewing the TLV2382ID datasheet, TLV2382ID pinout, TLV2382ID application, or TLV2382ID equivalent, key selection criteria include its 4.5 mV max input offset voltage over –40°C to 125°C, 90 nV/√Hz input noise, rail-to-rail output swing within 120 mV of rails at 2.7 V, and guaranteed operation down to single 2.7 V supply.
Technical Context
The TLV2382ID uses BiMOS input stage architecture to achieve 1 pA typical input bias current and rail-to-rail input common-mode range (–0.2 V to VS + 0.2 V). Its unity-gain-stable design delivers 0.06 V/µs slew rate and 62° phase margin with 100 pF load capacitance.
It operates across full industrial temperature range (–40°C to 125°C) with 7 µA/channel quiescent current at 2.7 V, supporting battery-powered systems requiring long runtime and stable dc performance without thermal derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-cell LiFePO₄ (2.7 V min) and dual ±8 V supplies |
| Gain-Bandwidth Product | 160 kHz - sufficient for DC-coupled sensor amplification and slow analog filtering |
| Input Offset Voltage (max) | 4.5 mV - enables accurate low-level signal amplification without trimming in cost-sensitive designs |
| Supply Current per Channel | 7 µA - allows continuous operation for years on coin-cell batteries in security sensors |
| Input Noise Voltage | 90 nV/√Hz - preserves SNR in high-impedance transducer interfaces like piezoelectric smoke detectors |
| Output Voltage Swing | Within 120 mV of rails at 2.7 V - maximizes dynamic range in low-voltage data acquisition |
| Common-Mode Rejection | 70 dB min - rejects power-supply ripple and EMI in noisy industrial environments |
Pinout & Package
TLV2382ID is housed in an 8-pin SOIC (D) package with 1.27 mm pitch, 3.91 mm × 4.90 mm body, and 1.75 mm max height. Thermal resistance θJA = 176 °C/W enables 710 mW power dissipation at TA ≤ 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Drives feedback network or next-stage input; rail-to-rail swing supports full-scale ADC interface |
| 2 (IN–1) | Channel 1 inverting input | Accepts feedback signal; low 1 pA bias current minimizes resistor-induced offset errors |
| 3 (IN+1) | Channel 1 non-inverting input | Receives sensor signal; rail-to-rail common-mode range accommodates ground-referenced sources |
| 4 (GND) | Analog ground reference | Shared return path for both channels; requires dedicated low-impedance ground plane |
| 5 (IN+2) | Channel 2 non-inverting input | Independent signal path; enables dual-sensor monitoring without cross-talk |
| 6 (IN–2) | Channel 2 inverting input | Configurable for differential or single-ended gain stages; matched to Pin 2 for common-mode rejection |
| 7 (OUT2) | Channel 2 output | Provides second independent amplified output; identical AC/DC specs to OUT1 |
| 8 (VDD) | Positive supply rail | Accepts 2.7–16 V; decoupling with 0.1 µF ceramic capacitor required within 2.5 mm |
Key Features

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 | Tape-and-reel packaging (2500 pcs), identical electrical specs and SOIC-8 footprint | No functional difference; optimized for automated SMT production vs. manual prototyping | Select TLV2382IDR for volume manufacturing; TLV2382ID for evaluation and low-volume builds |
| OPA2349EA/250 | Narrower supply range (1.8–5.5 V), lower 2 µA supply current, but only 70 kHz GBW and no rail-to-rail input | Suitable for sub-3.3 V systems only; insufficient for 5 V or 12 V industrial rails | Choose OPA2349EA/250 only when supply is strictly ≤5.5 V and bandwidth demand is <100 kHz |
Compared with TLV2382IDR, TLV2382ID offers identical performance in tube packaging for flexibility, while OPA2349EA/250 trades bandwidth and rail-to-rail input for lower quiescent current in ultra-low-voltage applications.

FAQ
What is the maximum recommended supply voltage for TLV2382ID?
The absolute maximum supply voltage for TLV2382ID is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Exceeding 16 V risks permanent damage, and operation below 2.7 V may cause undefined behavior or loss of rail-to-rail functionality. The device supports dual-supply operation down to ±1.35 V, making it compatible with two rechargeable cells.
Does TLV2382ID support rail-to-rail input at all supply voltages?
Yes, TLV2382ID supports rail-to-rail input common-mode range (–0.2 V to VS + 0.2 V) across its entire 2.7 V to 16 V supply range. This is confirmed in the "Recommended Operating Conditions" table and verified in Figure 1–3 of the SLOS377A datasheet, where input offset voltage remains stable across VIC from –0.2 V to VS + 0.2 V at 2.7 V, 5 V, and 15 V supplies.
What is the typical input bias current of TLV2382ID and how does it affect high-impedance circuits?
The typical input bias current of TLV2382ID is 1 pA at 25°C, with a maximum of 1000 pA over –40°C to 125°C. This ultra-low value minimizes voltage error across high-value feedback or source resistors-e.g., a 10 MΩ resistor contributes only 10 µV offset-making TLV2382ID ideal for photodiode transimpedance amplifiers and piezoelectric sensor interfaces.
Can TLV2382ID drive capacitive loads, and what is its phase margin with 50 pF?
TLV2382ID maintains 62° phase margin with a 50 pF capacitive load and 100 kΩ load resistance at 25°C, as specified in the "Dynamic Performance" table. It remains stable with up to 100 pF load when properly decoupled; for loads >50 pF, external isolation resistor (e.g., 10–50 Ω in series with output) is recommended to prevent peaking or oscillation.
Is TLV2382ID qualified for automotive applications?
TLV2382ID is rated for –40°C to 125°C operation and meets industrial-grade specifications, but it is not AEC-Q200 qualified or automotive grade. While it functions reliably in under-hood environments, TI does not certify TLV2382ID for safety-critical automotive systems; designers requiring ASIL-compliant components should select TI's automotive-qualified OPAx197 or TLV9062 families instead.
