Product details
Overview
TLV2382IDR from Texas Instruments is a dual-channel micropower rail-to-rail input/output operational amplifier designed for ultra-low-power sensor signal conditioning and battery-powered instrumentation. It delivers 160 kHz gain-bandwidth, 7 µA per channel supply current, and 90 nV/√Hz input noise voltage across –40°C to 125°C, enabling precision analog front-ends in portable medical devices and smoke detectors.
For engineers reviewing the TLV2382IDR datasheet, TLV2382IDR pinout, TLV2382IDR application, or TLV2382IDR equivalent, key selection considerations include its 2.7 V to 16 V single-supply operation, ±1.35 V to ±8 V dual-supply compatibility, rail-to-rail output swing down to 50 mV from rails at 15 V, and SOIC-8 package suitability for industrial-grade embedded monitoring systems.
Technical Context
The TLV2382IDR 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 160 kHz unity-gain bandwidth and 0.06 V/µs slew rate are optimized for low-frequency precision amplification with minimal quiescent power.
It operates across full industrial temperature range (–40°C to 125°C) with guaranteed 4.5 mV max input offset voltage and 70 dB min CMRR at 25°C, supporting stable DC-coupled configurations in power monitoring and low-power security detection circuits without external trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V single supply; enables direct operation from two 1.5 V alkaline cells or ±1.35 V to ±8 V dual supplies. |
| Supply Current per Channel | 7 µA typical at 2.7 V; supports >10-year battery life in always-on smoke detector analog front-ends. |
| Gain-Bandwidth Product | 160 kHz typical; sufficient for anti-aliasing filtering and sensor signal amplification up to ~100 kHz. |
| Input Offset Voltage | 4.5 mV maximum; ensures <±10 mV total error in 12-bit ADC interfacing with 3.3 V reference. |
| Input Bias Current | 1 pA typical; minimizes voltage drop across high-impedance pH or ion-selective electrode sensors. |
| Rail-to-Rail Output Swing | 50 mV from rails at 15 V; preserves dynamic range in single-supply data acquisition systems. |
| Input Noise Voltage | 90 nV/√Hz at 1 kHz; critical for low-level thermocouple or strain gauge signal integrity. |
Pinout & Package
TLV2382IDR is housed in an 8-pin SOIC (D) package with 1.27 mm lead pitch, 3.91 mm × 4.90 mm body, and 1.75 mm max height - compatible with standard surface-mount reflow profiles (MSL Level-1).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplified output of Channel A; drives loads up to 100 mA with rail-to-rail swing. |
| 2 | IN– A | Inverting input of Channel A; high-impedance node requiring guard ring layout for <1 pA leakage. |
| 3 | IN+ A | Non-inverting input of Channel A; accepts signals from –0.2 V to VS + 0.2 V common-mode range. |
| 4 | GND | Analog ground reference; must connect to low-inductance ground plane beneath device footprint. |
| 5 | VDD | Positive supply rail; requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling per TI layout guidelines. |
| 6 | IN– B | Inverting input of Channel B; electrically isolated from Channel A except via shared supply/ground paths. |
| 7 | IN+ B | Non-inverting input of Channel B; identical input range and bias current specs as Channel A. |
| 8 | OUT B | Amplified output of Channel B; supports independent gain configuration from Channel A. |

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 |
|---|---|---|---|
| TLV2382ID | Tubes vs tape-and-reel; identical electrical specs and SOIC-8 package. | No difference in circuit design or performance; only packaging format differs. | Select TLV2382ID for prototyping or low-volume hand-soldering; TLV2382IDR for automated SMT production. |
| OPA2349EA/250 | Lower supply voltage (1.8–5.5 V), lower IQ (2 µA), but reduced GBW (70 kHz) and narrower temp range (–40°C to 85°C). | Suitable only for 3.3 V systems with less demanding bandwidth needs and no extended temperature requirement. | Choose OPA2349EA/250 only if supply is strictly ≤5.5 V and 160 kHz bandwidth is unnecessary. |
Compared with TLV2382IDR, TLV2382ID offers identical performance in tube packaging for evaluation, while OPA2349EA/250 trades bandwidth and temperature range for lower quiescent current in narrow-voltage applications - making TLV2382IDR the optimal choice for industrial 2.7–16 V designs requiring full-spec performance.

FAQ
What is the maximum supply voltage rating for TLV2382IDR?
The absolute maximum supply voltage for TLV2382IDR is 16.5 V, with recommended operation from 2.7 V to 16 V single supply or ±1.35 V to ±8 V dual supply. Exceeding 16.5 V risks permanent damage per TI's absolute maximum ratings table in SLOS377A.
Does TLV2382IDR support rail-to-rail input and output simultaneously?
Yes, TLV2382IDR supports rail-to-rail input (common-mode range from –0.2 V to VS + 0.2 V) and rail-to-rail output (swing within 50 mV of rails at 15 V) simultaneously, enabling true single-supply operation without external level-shifting components in the TLV2382IDR signal path.
What is the input bias current specification for TLV2382IDR at 125°C?
At 125°C, the input bias current for TLV2382IDR is specified at a maximum of 1000 pA per channel, as confirmed in the "input characteristics" table of SLOS377A. This remains well below 1 nA, preserving accuracy in high-impedance sensor applications across the full industrial temperature range.
Can TLV2382IDR drive capacitive loads without instability?
TLV2382IDR maintains stability with up to 50 pF capacitive load, as shown in Figure 16 (Phase Margin vs Load Capacitance) of SLOS377A. For loads >50 pF, TI recommends adding a series resistor (typically 10–100 Ω) between the output and capacitor to isolate the pole and preserve phase margin.
Is TLV2382IDR RoHS compliant and what is its MSL rating?
Yes, TLV2382IDR is RoHS compliant with NIPDAU lead finish and carries JEDEC MSL Level-1 (260°C peak reflow, unlimited floor life), as documented in TI's Packaging Information addendum. This allows standard Pb-free reflow processes without moisture sensitivity concerns.
