Product details
Overview
TLV2462IDG4 from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for low-power portable and automotive applications. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage - enabling high-fidelity signal buffering in ADC front-ends and sensor interfaces operating from 2.7 V to 6 V.
For engineers reviewing the TLV2462IDG4 datasheet, TLV2462IDG4 pinout, TLV2462IDG4 application, or TLV2462IDG4 equivalent, this device is selected for precision analog signal conditioning where rail-to-rail swing, low quiescent current, and robust output drive across −40°C to 125°C are required - especially in battery-powered instrumentation and automotive control modules.
Technical Context
The TLV2462IDG4 integrates two independent amplifiers with complementary input stages enabling true rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing. Its architecture supports stable unity-gain operation with 160 pF capacitive load and provides 45° phase margin at 5 V supply.
Each channel features an active shutdown terminal (SHDN) that reduces supply current to 0.3 µA per channel while placing the output in high-impedance state. The device is specified over industrial and automotive temperature ranges (−40°C to 125°C) and qualified to AEC-Q100 standards for automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop operation up to ~1 MHz with moderate gain (e.g., AV = 5), suitable for anti-aliasing and reconstruction filters. |
| Slew Rate | 1.6 V/µs - supports clean 100 kHz full-scale sine wave output at 2 VPP without distortion in unity-gain buffer configurations. |
| Supply Current per Channel | 500 µA - allows continuous operation in always-on sensor signal chains powered by coin cells or energy-harvesting sources. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.002% gain error in 5 V full-scale 12-bit systems, minimizing calibration burden. |
| Output Drive Capability | ±80 mA - drives 62 Ω loads directly (e.g., 50 Ω coax + termination) without external buffers in data acquisition front-ends. |
| Rail-to-Rail I/O | Input common-mode range: 0 V to VDD; Output swing: within 100 mV of rails - maximizes dynamic range in single-supply 3.3 V systems. |
| Shutdown Current | 0.3 µA per channel - enables microamp-level system sleep modes while retaining fast wake-up (<8 µs turn-on time). |
Pinout & Package
TLV2462IDG4 is housed in an 8-pin MSOP (DGK) package with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm. This thermally enhanced package supports reliable operation at 125°C ambient in space-constrained automotive and industrial PCB layouts.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting or non-inverting output of Channel A; capable of sourcing/sinking ±80 mA with rail-to-rail swing. |
| 2 | IN− A | Inverting input of Channel A; high-impedance node (10⁹ Ω) with 1300 pA bias current at 25°C. |
| 3 | IN+ A | Non-inverting input of Channel A; accepts common-mode signals from 0 V to VDD. |
| 4 | GND | Analog ground reference for both channels; must be low-impedance connection to minimize noise coupling. |
| 5 | IN+ B | Non-inverting input of Channel B; electrically isolated from Channel A except via shared supply and ground. |
| 6 | IN− B | Inverting input of Channel B; matched offset and bias characteristics to Channel A for differential pair use. |
| 7 | OUT B | Output of Channel B; identical AC/DC performance to OUT A; supports independent shutdown control. |
| 8 | VDD+ | Positive supply rail (2.7–6 V); supplies both amplifiers and internal bias circuitry; bypass capacitor required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3 V or 5 V supply in single-ended configurations - no level-shifting needed for ADC drivers. |
| 6.4 MHz GBW with 1.6 V/µs slew rate | Supports 12-bit settling in <2 µs for 10 kΩ/10 pF loads - meets timing requirements of SAR ADC sampling clocks. |
| 500 µA/channel quiescent current | Reduces total system power by >70% vs. legacy 2 mA/opamp solutions - critical for multi-channel portable instruments. |
| 0.3 µA/channel shutdown mode | Permits selective channel disabling in multi-sensor nodes without affecting adjacent signal paths or requiring layout changes. |
| Specified from −40°C to 125°C | Validated for under-hood automotive and industrial motor-control environments without derating or thermal margin loss. |
| ±80 mA output drive | Drives 100 Ω transmission lines or multiple 10 kΩ inputs directly - eliminates need for discrete output buffers in compact designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Same silicon die and specifications; differs only in tape-and-reel packaging (DR suffix) vs. tube (DG4 suffix). | No functional difference; DR variant intended for automated SMT assembly; DG4 for manual prototyping or low-volume production. | Select TLV2462IDG4 for hand-soldering, evaluation, or small-batch builds; TLV2462IDR for high-volume pick-and-place lines. |
| OPA2340UA | Higher GBW (12 MHz), lower noise (7 nV/√Hz), but higher supply current (750 µA/ch); no shutdown function; same MSOP-8 package. | Better for wideband sensor interfaces (e.g., ultrasonic transducers); unsuitable where ultra-low standby power is mandatory. | Choose OPA2340UA when bandwidth or noise dominates design priority; retain TLV2462IDG4 when power budget or shutdown control is critical. |
Compared with TLV2462IDR, TLV2462IDG4 offers identical electrical performance in tube packaging for flexibility in low-volume or development workflows; versus OPA2340UA, TLV2462IDG4 trades 5.6 MHz bandwidth and 4 nV/√Hz noise for 250 µA/ch lower quiescent current and integrated shutdown - making it superior for always-on, battery-sensitive systems.

FAQ
What is the operating temperature range for TLV2462IDG4?
The TLV2462IDG4 is rated for operation from −40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 2 requirements for automotive under-hood applications. This range is validated across all key parameters including input offset voltage, supply current, and output drive capability - no derating is required within this span.
Does TLV2462IDG4 include a shutdown feature?
Yes, TLV2462IDG4 includes an active-low shutdown pin (SHDN) on Pin 5 of the MSOP-8 package. When pulled below 0.7 V, each amplifier channel enters ultralow-power mode drawing just 0.3 µA per channel while its output goes to high impedance - enabling precise power gating in multi-channel systems.
What is the maximum capacitive load TLV2462IDG4 can drive stably?
TLV2462IDG4 maintains stability with up to 160 pF capacitive load in unity-gain configuration at 5 V supply, delivering 45° phase margin. For loads exceeding 100 pF, TI recommends adding a 10 Ω series resistor between the output and capacitance to preserve stability without degrading signal integrity.
How does TLV2462IDG4 perform in single-supply 3.3 V systems?
In 3.3 V single-supply operation, TLV2462IDG4 delivers rail-to-rail input (0–3.3 V) and output (within 100 mV of rails), 6.4 MHz GBW, and 1.6 V/µs slew rate - enabling accurate buffering of full-scale 12-bit ADC inputs. Input offset remains ≤1500 µV across temperature, ensuring minimal gain error.
Is TLV2462IDG4 pin-compatible with other dual op-amps in MSOP-8?
TLV2462IDG4 uses a non-standard pinout: Pins 1–4 serve Channel A (OUT/IN−/IN+/GND), while Pins 5–8 serve Channel B (IN+/IN−/OUT/VDD+). It is not pin-compatible with generic dual op-amps like LMV722 or MCP6022. Layout must follow the specific TLV2462 pin mapping shown in the datasheet Figure 4.
