Product details
Overview
TLV2462IDGKRG4 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 TLV2462IDGKRG4 datasheet, TLV2462IDGKRG4 pinout, TLV2462IDGKRG4 application, or TLV2462IDGKRG4 equivalent, this page provides verified package mapping (MSOP-8), shutdown functionality (SHDN pin), rail-to-rail dynamic range, and validated alternatives for industrial temperature-range op-amp replacement.
Technical Context
The TLV2462IDGKRG4 integrates two independent amplifiers with rail-to-rail input common-mode range extending beyond supply rails and rail-to-rail output swing - critical for maximizing dynamic range in single-supply systems down to 2.7 V. Its 6.4 MHz GBW and 1.6 V/µs slew rate support medium-speed signal conditioning without excessive power penalty.
Each channel features an active-low 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 across −40°C to +125°C and qualified for automotive Q-Temp applications, with input offset voltage ≤1500 µV over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable unity-gain buffer operation up to ~6 MHz with minimal phase margin degradation. |
| Slew Rate | 1.6 V/µs - enables clean 10-bit ADC sampling at ≥100 kSPS with <0.1% distortion in buffered configurations. |
| Supply Current / Channel | 500 µA - allows dual-op-amp integration in battery-powered systems with multi-day runtime on coin cells. |
| Rail-to-Rail I/O | Input extends beyond rails; output swings within 100 mV of VDD/GND at 10 mA load - maximizes usable signal range in 3.3 V systems. |
| Input Offset Voltage | 100 µV (typ), ≤1500 µV (max over −40°C to +125°C) - ensures sub-LSB error in 12-bit precision sensor signal chains. |
| Shutdown Current | 0.3 µA/channel - enables ultra-low-power sleep mode in always-on monitoring circuits without external disconnect switches. |
| Output Drive | ±80 mA - drives 50 Ω transmission lines or multiple parallel inputs without external buffers. |
Pinout & Package
TLV2462IDGKRG4 is housed in an 8-pin MSOP (DGK) package with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.05 mm. This thermally enhanced surface-mount package supports high-density PCB layouts and improves power dissipation in industrial environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | High-drive rail-to-rail output capable of sourcing/sinking ±80 mA; high-impedance during shutdown. |
| 2 (IN− A) | Channel A inverting input | Differential input node with 1300 pA bias current (typ) and rail-to-rail common-mode range. |
| 3 (IN+ A) | Channel A non-inverting input | Matches IN− A; supports input voltages from GND − 0.2 V to VDD + 0.2 V. |
| 4 (GND) | Analog ground reference | Primary return path for both channels and shutdown logic; must be low-impedance connection. |
| 5 (SHDN) | Active-low shutdown control | Pull ≤0.7 V to disable both amplifiers; pull ≥2 V to enable; CMOS-compatible logic interface. |
| 6 (VDD+) | Positive supply rail | Accepts 2.7 V to 6 V; internal regulation ensures stable biasing across full voltage and temperature range. |
| 7 (IN+ B) | Channel B non-inverting input | Independent of Channel A; identical electrical specs and rail-to-rail input capability. |
| 8 (IN− B) | Channel B inverting input | Paired with Pin 7; matched offset and bias performance to Channel A for differential applications. |

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, same MSOP-8 package, but without tape-and-reel suffix (G4); identical electrical specs and temperature rating. | No functional difference; intended for different packaging logistics (bulk vs. reel). | Select TLV2462IDGKRG4 for automated SMT assembly requiring 1000-unit reels; TLV2462IDR for prototyping or low-volume hand-soldering. |
| OPA2340UA/2K5 | Higher GBW (10 MHz), lower noise (7 nV/√Hz), but higher supply current (800 µA/ch); no shutdown function; SOIC-8 only. | Better AC performance for audio or higher-speed data acquisition; lacks power-gating capability for battery systems. | Choose OPA2340UA/2K5 when bandwidth/noise priority outweighs power budget; avoid where shutdown or MSOP footprint is required. |
Compared with TLV2462IDGKRG4, TLV2462IDR offers identical performance in a non-reel format, while OPA2340UA/2K5 trades 300 µA/channel extra current for 3.6 MHz more bandwidth and 4 nV/√Hz less noise - making it suitable only when shutdown and compact MSOP are not mandatory.

FAQ
What is the operating temperature range for TLV2462IDGKRG4?
The TLV2462IDGKRG4 is rated for continuous operation from −40°C to +125°C, meeting automotive Q-Temp requirements. This extended range is validated across all key parameters including input offset voltage (≤1500 µV), supply current (≤0.9 mA/channel), and output drive (±80 mA), ensuring reliability in under-hood and industrial control environments.
Does TLV2462IDGKRG4 support true rail-to-rail input and output?
Yes, TLV2462IDGKRG4 supports rail-to-rail input common-mode voltage range (extending 0.2 V beyond VDD and GND) and rail-to-rail output swing (within 100 mV of each rail at 10 mA load). This is confirmed in the datasheet's "Common-mode input voltage range" (0 to VDD) and "Output voltage swing" specifications across 2.7 V to 6 V supplies.
How does the shutdown feature work on TLV2462IDGKRG4?
The TLV2462IDGKRG4 uses an active-low SHDN pin (Pin 5): pulling it ≤0.7 V disables both amplifiers and reduces total supply current to ≤0.6 µA (0.3 µA per channel), while placing outputs in high-impedance state. Pulling SHDN ≥2 V enables normal operation. No external pull-up is required, as internal logic handles state retention.
What is the maximum capacitive load TLV2462IDGKRG4 can drive stably?
TLV2462IDGKRG4 maintains ≥30° phase margin with loads up to 160 pF when driving 10 kΩ resistive loads, as shown in Figure 36 of the datasheet. For heavier capacitive loads (>200 pF), external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to prevent peaking or oscillation in unity-gain configurations.
Is TLV2462IDGKRG4 pin-compatible with other TLV246x variants in MSOP-8?
Yes, TLV2462IDGKRG4 shares identical pinout with all TLV2462x variants in DGK (MSOP-8) package, including TLV2462IDGKR and TLV2462AIDGKR. Pin functions - OUT A, IN− A, IN+ A, GND, SHDN, VDD+, IN+ B, IN− B - are fixed across the family, enabling drop-in replacement within the same temperature grade and suffix group.
