Product details
Overview
TLV2462IDGKR from Texas Instruments is a dual rail-to-rail input/output operational amplifier designed for low-voltage portable and automotive signal conditioning. It delivers 6.4 MHz gain-bandwidth, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage - enabling high-fidelity buffering of ADC inputs in battery-powered systems.
For engineers reviewing the TLV2462IDGKR datasheet, TLV2462IDGKR pinout, TLV2462IDGKR application, or TLV2462IDGKR equivalent, this page provides verified electrical specs, MSOP-8 package details, shutdown functionality validation, and direct alternatives for rail-to-rail op-amp selection in industrial and automotive analog front-ends.
Technical Context
The TLV2462IDGKR implements a complementary input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing. Its architecture supports stable operation with capacitive loads up to 160 pF while maintaining 45° phase margin at unity gain.
It integrates independent shutdown control per channel (SHDN pins 1 and 8), reducing supply current to 0.3 µA/channel when asserted low (<0.7 V), with output placed in high-impedance state - critical for power-gated sensor interfaces and multiplexed signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop operation up to ~500 kHz with gain ≥12 in unity-gain-compensated configurations. |
| Slew Rate | 1.6 V/µs - supports 10-bit ADC sampling at 1 MSPS with <0.1% distortion for 2-VPP signals. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.001% gain error in precision 12-bit sensor amplification at room temperature. |
| Supply Current / Channel | 500 µA - allows dual-channel operation from coin-cell or energy-harvesting sources without compromising bandwidth. |
| Rail-to-Rail I/O | Full 0 V to VDD input range and output swing - eliminates level-shifting circuitry in single-supply 3.3 V or 5 V systems. |
| Shutdown Current | 0.3 µA/channel - reduces total system quiescent current by >99.9% during idle periods in duty-cycled measurement nodes. |
| Output Drive | ±80 mA - drives 10 kΩ loads to rails while sourcing/sinking 10 mA into 100 Ω, supporting active filtering and DAC output buffering. |
Pinout & Package
TLV2462IDGKR is housed in an 8-pin MSOP (DGK) package - 3.0 mm × 3.0 mm × 1.0 mm body, 0.65 mm pitch - optimized for high-density PCB layouts in automotive ECUs and portable instrumentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN1) | Channel 1 shutdown control | Active-low logic input; <0.7 V disables Channel 1, placing OUT1 in high-Z and reducing IDD by 500 µA. |
| 2 (IN1−) | Channel 1 inverting input | Differential input node with 1300 pA bias current; supports rail-to-rail common-mode range (0 V to VDD). |
| 3 (IN1+) | Channel 1 non-inverting input | Matches IN1− in offset and noise; enables precision instrumentation amplifier configurations with matched external resistors. |
| 4 (GND) | Analog ground reference | Primary return path for both channels; must be connected to low-impedance system ground plane to maintain CMRR >60 dB. |
| 5 (IN2+) | Channel 2 non-inverting input | Independent input with same DC specs as IN1+; supports dual-sensor differential acquisition without cross-talk. |
| 6 (IN2−) | Channel 2 inverting input | Electrically isolated from Channel 1 inputs; enables simultaneous dual-channel filtering or gain stages. |
| 7 (OUT2) | Channel 2 output | Rail-to-rail capable output driving ±80 mA; maintains 11 nV/√Hz input-referred noise up to 10 kHz. |
| 8 (SHDN2) | Channel 2 shutdown control | Independent of SHDN1; allows asymmetric power gating - e.g., keep Channel 1 active while disabling Channel 2 for standby monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 2.7–6 V single-supply systems without external level shifters or dual supplies. |
| Independent per-channel shutdown | Reduces system-level quiescent power by selectively disabling unused amplifiers - essential for multi-sensor IoT edge nodes. |
| Low input noise (11 nV/√Hz) | Maintains SNR >80 dB for 1 kHz sensor signals with 10 kΩ source impedance, supporting high-resolution delta-sigma ADC drivers. |
| High output drive (±80 mA) | Directly drives RC anti-aliasing filters, LED indicators, or 50 Ω transmission lines without external buffers in compact designs. |
| Automotive-grade temperature range | Specified from −40°C to +125°C (I-suffix), qualified to AEC-Q100 - suitable for under-hood and ADAS front-end signal conditioning. |

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 die, SOIC-8 package (4.9 mm × 3.9 mm); higher thermal resistance (θJA = 122.6°C/W vs. 259.9°C/W for DGK). | Preferred where board space permits larger footprint and manual rework is required; less suitable for high-density automotive modules. | Select TLV2462IDR only if SOIC-8 layout compatibility or legacy footprint reuse is mandatory. |
| OPA2333AIDGKR | Zero-drift architecture; 0.02 µV/°C offset drift vs. 2 µV/°C for TLV2462; higher supply current (17 µA/ch) and lower GBW (350 kHz). | Better for ultra-low-drift DC applications (e.g., precision weigh scales); unsuitable for AC-coupled audio or fast sensor signals. | Choose OPA2333AIDGKR only when long-term DC stability outweighs bandwidth and power requirements. |
Compared with TLV2462IDGKR, TLV2462IDR offers identical performance in a larger, more manufacturable package but sacrifices thermal efficiency and board density; OPA2333AIDGKR trades bandwidth and power for near-zero drift - making TLV2462IDGKR optimal for cost-sensitive, medium-speed, rail-to-rail signal conditioning where moderate DC accuracy suffices.

FAQ
What is the operating temperature range for TLV2462IDGKR?
The TLV2462IDGKR is rated for operation from −40°C to +125°C (I-suffix grade), meeting AEC-Q100 stress test requirements for automotive under-hood and industrial control environments. This range is validated across all key parameters including input offset voltage, CMRR, and output drive capability - ensuring consistent performance in extreme thermal conditions without derating.
Does TLV2462IDGKR support true rail-to-rail input and output?
Yes, TLV2462IDGKR supports true rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swing within 10 mV of either rail under 10 mA load). This is achieved via complementary input transistor pairs and optimized output stage design - eliminating need for external level-shifting circuitry in single-supply 3.3 V or 5 V systems using TLV2462IDGKR.
How does the shutdown feature work on TLV2462IDGKR?
TLV2462IDGKR features two independent shutdown pins (SHDN1 on Pin 1, SHDN2 on Pin 8). When pulled below 0.7 V, each pin disables its respective amplifier channel, reducing supply current to 0.3 µA/channel and placing the output in high-impedance state. Both channels remain fully functional when SHDN pins are held above 2 V - enabling flexible power sequencing in multi-stage analog signal paths using TLV2462IDGKR.
What is the maximum capacitive load TLV2462IDGKR can drive stably?
TLV2462IDGKR maintains stable unity-gain operation with capacitive loads up to 160 pF when driving a 10 kΩ load, as confirmed by phase margin measurements of 45° at 25°C. For loads exceeding 160 pF, external series resistance (≥10 Ω) at the output is recommended to preserve stability - a requirement documented in the TLV2462IDGKR datasheet's capacitive load vs. load resistance characterization.
Is TLV2462IDGKR pin-compatible with other dual op-amps in MSOP-8?
No, TLV2462IDGKR uses a proprietary pinout: SHDN1/IN1−/IN1+/GND/IN2+/IN2−/OUT2/SHDN2. It is not pin-compatible with standard dual op-amps like LMV358 or MCP6022 in MSOP-8. Layout migration requires netlist update and routing revision - confirming pin mapping against the TLV2462IDGKR datasheet is mandatory before PCB redesign involving TLV2462IDGKR.
