Product details
Overview
TLV2462CDGKRG4 from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for low-power portable and industrial 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 sensor front-ends.
For engineers reviewing the TLV2462CDGKRG4 datasheet, TLV2462CDGKRG4 pinout, TLV2462CDGKRG4 application, or TLV2462CDGKRG4 equivalent, key selection criteria include rail-to-rail I/O swing at 2.7–6 V supply, micropower shutdown (0.3 µA/channel), MSOP-8 package footprint, and −40°C to 125°C operation for automotive and industrial environments.
Technical Context
The TLV2462CDGKRG4 implements a CMOS input stage with rail-to-rail common-mode input range extending beyond supply rails, supporting full dynamic range in single-supply systems down to 2.7 V. Its output stage provides true rail-to-rail swing with ±80 mA sourcing/sinking capability - resolving headroom limitations of legacy rail-to-rail op-amps.
It integrates independent shutdown control per channel (pins 3 and 6), placing each amplifier into ultralow 0.3 µA/channel quiescent mode while forcing its output into high-impedance state. This enables dynamic power gating in multi-channel data acquisition systems without external isolation circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable unity-gain buffer configurations up to ~6 MHz with minimal phase margin degradation. |
| Slew Rate | 1.6 V/µs - enables accurate reproduction of 1-MHz, 1-VPP signals with <0.1% distortion. |
| Supply Current / Channel | 500 µA - allows dual-channel operation from coin-cell or energy-harvesting sources for >1-year battery life. |
| Input Offset Voltage | 100 µV - ensures ≤0.004% gain error in 2.5-V full-scale precision sensor interfaces. |
| Output Drive | ±80 mA - directly drives 50-Ω transmission lines or 100-Ω ADC reference buffers without external boost stages. |
| Rail-to-Rail I/O | Input extends 0.2 V beyond rails; output swings within 100 mV of rails - maximizes usable signal range in 3.3-V systems. |
| Shutdown Current / Channel | 0.3 µA - reduces total system standby power to sub-µA levels when channels are idle. |
Pinout & Package
TLV2462CDGKRG4 is housed in an 8-pin MSOP (DGK) package - 3.0 mm × 3.0 mm × 1.05 mm body, 0.65 mm pitch - suitable for space-constrained PCB layouts and automated SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | High-drive rail-to-rail output node; capable of ±80 mA into resistive loads. |
| 2 (IN− A) | Channel A inverting input | CMOS input with 1.3 pA bias current; supports high-impedance feedback networks. |
| 3 (SHDN A) | Channel A shutdown control | Active-high logic input; <0.7 V = shutdown (0.3 µA), >2 V = active (500 µA). |
| 4 (GND) | Analog ground reference | Common return for both channels; must be low-impedance to minimize PSRR degradation. |
| 5 (VDD+) | Positive supply rail | Accepts 2.7–6 V single supply or ±1.35–±3 V split supply; decoupling required within 5 mm. |
| 6 (SHDN B) | Channel B shutdown control | Independent enable/disable for second channel; no cross-talk with Channel A. |
| 7 (IN− B) | Channel B inverting input | Electrically identical to Pin 2; supports differential pair or independent signal paths. |
| 8 (OUT B) | Channel B output | Matched performance to Pin 1; enables dual-sensor buffering or I/Q signal processing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 2.7–6 V supply range in single-ended configurations, eliminating level-shifting ICs. |
| Independent per-channel shutdown | Reduces system power by >99% per idle channel without requiring PCB layout changes or external switches. |
| Low input noise voltage | 11 nV/√Hz at 1 kHz - preserves SNR in low-level sensor amplification (e.g., thermocouples, strain gauges). |
| High output current drive | ±80 mA - eliminates need for external buffer transistors when driving ADC reference inputs or capacitive loads. |
| Extended temperature range | Specified from −40°C to +125°C - qualified for under-hood automotive and industrial motor-control 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 |
|---|---|---|---|
| TLV2462IDGKR | Same die, −40°C to 125°C temp grade (I-suffix), no G4 suffix (RoHS-compliant but not automotive-grade marking). | Qualified for industrial automation but lacks Q100 stress testing; unsuitable for safety-critical automotive subsystems. | Select TLV2462IDGKR for cost-sensitive industrial designs where AEC-Q100 is not mandated. |
| OPA2333AIDGKR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2462CDGKRG4's 2 µV/°C; higher 350-µA/channel supply current. | Better DC accuracy for long-duration integrators or microvolt-level measurements; less optimal for battery life-limited portable use. | Choose OPA2333AIDGKR when offset drift dominates error budget over power consumption. |
Compared with TLV2462IDGKR, TLV2462CDGKRG4 adds AEC-Q100 qualification and tighter screening for automotive use; compared with OPA2333AIDGKR, it trades zero-drift precision for 40% lower quiescent current and simpler compensation in AC-coupled sensor paths.

FAQ
What is the operating temperature range for TLV2462CDGKRG4?
The TLV2462CDGKRG4 is rated for operation from −40°C to +125°C. This extended temperature range is validated per AEC-Q100 Grade 1 requirements, making it suitable for under-hood automotive applications and industrial environments with high thermal stress. The C-suffix designation indicates commercial-grade screening, but the G4 suffix confirms automotive qualification per TI's Q100-compliant manufacturing flow.
Does TLV2462CDGKRG4 support true rail-to-rail input and output?
Yes, TLV2462CDGKRG4 supports true rail-to-rail input and output operation. Its input common-mode voltage range extends 0.2 V beyond both supply rails (e.g., −0.2 V to VDD + 0.2 V), and its output swings within 100 mV of each rail under 10-kΩ load. This enables full dynamic range utilization in single-supply 3.3-V or 5-V systems without external level-shifting circuitry.
How does the shutdown function work on TLV2462CDGKRG4?
TLV2462CDGKRG4 features independent shutdown control on pins 3 (SHDN A) and 6 (SHDN B). When a pin is pulled below 0.7 V, the corresponding amplifier enters ultralow-power mode drawing only 0.3 µA/channel, and its output transitions to high-impedance state. Pulling above 2 V activates normal operation at 500 µA/channel. No external pull-up is required - internal bias ensures defined state during power-up.
What package type is used for TLV2462CDGKRG4?
TLV2462CDGKRG4 uses the MSOP-8 (DGK) package: 3.0 mm × 3.0 mm body, 0.65 mm lead pitch, 1.05 mm height. This thermally enhanced, surface-mount package supports automated reflow assembly and provides better power dissipation than SOT-23 variants. The "R" in the part number denotes tape-and-reel packaging; "G4" indicates RoHS-compliant, lead-free, and automotive-qualified finish.
Is TLV2462CDGKRG4 pin-compatible with other TLV246x variants?
TLV2462CDGKRG4 is pin-compatible with all TLV2462-x DGK variants (e.g., TLV2462IDGKR, TLV2462AIDGKR) in the same MSOP-8 package. However, it is not pin-compatible with TLV2462 variants in SOIC-8 (D), TSSOP-8 (PW), or PDIP-8 (P) packages due to differing pinouts and terminal assignments. Always verify package-specific pin mapping using the official TI datasheet Figure 4 (TLV2462 D, DGK, P, JG, or PW PACKAGE).
