Product details
Overview
TLV2382IDG4 from Texas Instruments is a dual-channel micropower rail-to-rail input/output operational amplifier optimized for ultra-low-power, single-supply systems. It delivers 160 kHz gain-bandwidth, 7 µA per channel supply current, 90 nV/√Hz input voltage noise, and operates from 2.7 V to 16 V across –40°C to 125°C - enabling use in portable medical sensors and low-power smoke detectors.
For engineers reviewing the TLV2382IDG4 datasheet, TLV2382IDG4 pinout, TLV2382IDG4 application, or TLV2382IDG4 equivalent, key selection criteria include its rail-to-rail I/O swing at sub-10 µA quiescent current, guaranteed industrial temperature operation, and SOIC-8 package compatibility with legacy TLC27Lx upgrades.
Technical Context
The TLV2382IDG4 employs BiMOS input stage architecture to achieve 1 pA typical input bias current and rail-to-rail common-mode input range (–0.2 V to VS + 0.2 V). Its output stage supports rail-to-rail swing within 120 mV of each rail at VS = 2.7 V and 50 mV at VS = 15 V under 100 µA load.
It features 160 kHz unity-gain bandwidth and 0.06 V/µs slew rate at unity gain, with phase margin >62° into 100 kΩ || 50 pF. Power supply rejection ratio exceeds 74 dB across 2.7–16 V, supporting stable operation in noisy battery-powered environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-cell LiFePO₄ (2.8 V), two alkaline cells (3 V), and up to ±8 V split supplies. |
| Quiescent Current / Channel | 7 µA typical - enables multi-year battery life in always-on sensor nodes drawing <15 µA total. |
| Gain-Bandwidth Product | 160 kHz - sufficient for DC–100 Hz biosignal amplification (ECG, pulse oximetry) with stable unity-gain configuration. |
| Input Offset Voltage | 4.5 mV max - ensures ≤100 µV output error in 100× gain instrumentation front-ends at room temperature. |
| Input Bias Current | 1 pA typical - minimizes voltage error across high-impedance pH or ion-selective electrodes (>100 MΩ source). |
| Input Noise Voltage | 90 nV/√Hz at 1 kHz - enables detection of microvolt-level signals in low-frequency industrial monitoring. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive power monitoring and industrial process control enclosures. |
Pinout & Package
TLV2382IDG4 is housed in an 8-pin SOIC (D) package with 1.27 mm lead pitch and 1.75 mm maximum height, compatible with standard surface-mount assembly and IPC-7351 land patterns.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 100 mA short-circuit current; rail-to-rail swing enables full dynamic range utilization. |
| 2 | IN– A | Inverting input of Channel A - high-impedance node requiring guard ring layout to preserve 1 pA bias current performance. |
| 3 | IN+ A | Non-inverting input of Channel A - accepts common-mode voltages from –0.2 V to VS + 0.2 V, enabling true single-supply sensor interfacing. |
| 4 | GND | Analog ground reference - must connect to low-impedance ground plane; shared return for both channels and supply decoupling. |
| 5 | VDD | Positive supply rail - requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling per TI layout guidelines. |
| 6 | IN+ B | Non-inverting input of Channel B - electrically isolated from Channel A; supports independent sensor conditioning paths. |
| 7 | IN– B | Inverting input of Channel B - matched offset and bias specs to Channel A for differential pair configurations. |
| 8 | OUT B | Amplifier B output - identical AC/DC specs to Pin 1; enables dual-sensor readout or signal buffering without external components. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal acquisition from 0 V to VS in single-supply systems - eliminates level-shifting circuitry in battery-powered designs. |
| 160 kHz GBW at 7 µA | Delivers usable bandwidth for DC–100 Hz applications while consuming <1% of the current of comparable 1 MHz op-amps. |
| 1 pA input bias current | Preserves signal integrity when interfacing with high-impedance sources like piezoelectric sensors or electrochemical cells. |
| –40°C to 125°C operation | Qualified for extended industrial environments without derating - supports deployment in uncontrolled ambient conditions. |
| SOIC-8 footprint | Provides drop-in upgrade path from TLC27L2 and TLV2372 while improving bandwidth and reducing quiescent current by 40%. |

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 | Identical electrical specs; tape-and-reel packaging (2500 pcs) vs. tube (75 pcs) for TLV2382IDG4. | No functional difference - selected for automated SMT production vs. prototyping/hand-soldering. | Choose TLV2382IDR for volume manufacturing; TLV2382IDG4 for evaluation and low-volume builds. |
| TLC27L2CD | Higher 17 µA supply current, narrower 85 kHz GBW, and non-rail-to-rail inputs (VICR = –0.2 V to VS – 1.2 V). | Limited to higher-voltage, lower-bandwidth applications where rail-to-rail I/O is not required. | TLV2382IDG4 offers 59% lower IQ and 88% higher bandwidth - preferred for modern ultra-low-power designs. |
Compared with TLC27L2CD and TLV2382IDR, TLV2382IDG4 provides the lowest quiescent current and widest bandwidth in SOIC-8 dual op-amp form factor, making it optimal for energy-constrained applications requiring rail-to-rail signal handling without sacrificing precision.

FAQ
What is the maximum supply voltage rating for TLV2382IDG4?
The absolute maximum supply voltage for TLV2382IDG4 is 16.5 V, with recommended operating range from 2.7 V to 16 V. Exceeding 16.5 V risks permanent damage. Operation at 16 V enables compatibility with ±8 V split supplies or high-voltage single-ended rails in industrial monitoring applications using the TLV2382IDG4.
Does TLV2382IDG4 support rail-to-rail input and output simultaneously?
Yes, TLV2382IDG4 supports rail-to-rail input common-mode range (–0.2 V to VS + 0.2 V) and rail-to-rail output swing (within 50–220 mV of each rail depending on load and supply). This allows true single-supply operation with full dynamic range utilization - a key capability confirmed in the SLOS377A datasheet for TLV2382IDG4.
What is the input bias current specification for TLV2382IDG4 at 125°C?
Per the SLOS377A datasheet, TLV2382IDG4 has a maximum input bias current of 1000 pA at 125°C (full temperature range). At 25°C, typical IIB is 1 pA - critical for high-impedance sensor interfacing. This parameter is explicitly characterized and verified for TLV2382IDG4 across its full operating range.
Is TLV2382IDG4 pin-compatible with TLC27L2CD?
Yes, TLV2382IDG4 is pin-compatible with TLC27L2CD in the SOIC-8 (D) package. Both share identical pinout: OUT A, IN– A, IN+ A, GND, VDD, IN+ B, IN– B, OUT B. However, TLV2382IDG4 improves bandwidth (160 kHz vs. 85 kHz) and reduces supply current (7 µA vs. 17 µA), making it a direct performance upgrade.
What thermal considerations apply to TLV2382IDG4 in SOIC-8 package?
TLV2382IDG4 in SOIC-8 has θJA = 176°C/W and θJC = 38.3°C/W. At 25°C ambient and 15 µA max total supply current (2 × 7.5 µA), power dissipation is ~0.24 mW - resulting in negligible junction temperature rise. Full-range derating is only required above ~700 mW dissipation, far beyond normal operation of TLV2382IDG4.
