Product details
Overview
TLV2462CDGKG4 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 ADC buffering in battery-powered sensor front-ends.
For engineers reviewing the TLV2462CDGKG4 datasheet, TLV2462CDGKG4 pinout, TLV2462CDGKG4 application, or TLV2462CDGKG4 equivalent, this page provides verified package mapping (MSOP-8), confirmed shutdown functionality, rail-to-rail dynamic range at 2.7–6 V operation, and real-world design guidance for precision analog interfaces in automotive and industrial environments.
Technical Context
The TLV2462CDGKG4 integrates two independent amplifiers with complementary input stages enabling rail-to-rail common-mode input voltage range (0 V to VDD) and rail-to-rail output swing. Its architecture supports stable unity-gain operation with 160 pF capacitive load and achieves 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 operates across −40°C to 125°C (I-suffix grade), meeting Q-Temp automotive qualification requirements for under-hood and body-control applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop operation up to ~500 kHz at gain = 10 without excessive phase lag. |
| Slew Rate | 1.6 V/µs - supports 10-bit ADC sampling of 100 kHz signals with <0.1% distortion at 2 VPP. |
| Input Offset Voltage | 100 µV - ensures ≤0.004% error in 2.5 V full-scale 16-bit measurement systems. |
| Supply Current / Channel | 500 µA - allows continuous operation on coin-cell batteries for >1 year in always-on sensor nodes. |
| Rail-to-Rail I/O | Input range: 0 V to VDD; Output swing: within 100 mV of rails at 10 mA load - maximizes dynamic range in single-supply 3.3 V systems. |
| Shutdown Current | 0.3 µA/channel - reduces total system standby power to sub-microwatt levels when inactive. |
| Output Drive | ±80 mA - directly drives 50 Ω transmission lines or multiple CMOS inputs without external buffers. |
Pinout & Package
TLV2462CDGKG4 is housed in an 8-pin MSOP (DGK) package with 0.65 mm pitch, 3.0 mm × 3.0 mm footprint, and exposed thermal pad for enhanced power dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers rail-to-rail buffered signal; high-impedance during SHDN assertion. |
| 2 (IN− A) | Channel A inverting input | Differential input node; supports feedback networks up to 10 MΩ without significant bias-current error. |
| 3 (IN+ A) | Channel A non-inverting input | Accepts common-mode voltages from GND to VDD; enables single-supply sensor interfacing. |
| 4 (GND) | Analog ground reference | Common return path for both channels; must be low-impedance and separated from digital ground. |
| 5 (SHDN) | Active-high shutdown control | Drives output to high-Z when <0.7 V; enables power gating in multi-stage analog chains. |
| 6 (VDD+) | Positive supply rail | Supports 2.7–6 V operation; internal regulation ensures consistent performance across battery discharge. |
| 7 (IN+ B) | Channel B non-inverting input | Independent input for second signal path; shares same rail-to-rail input range as Channel A. |
| 8 (IN− B) | Channel B inverting input | Enables differential or single-ended configurations for dual-channel signal processing. |

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, I-suffix (−40°C to 125°C), SOIC-8 package, no exposed thermal pad. | Larger footprint; lower thermal resistance not required in low-power ambient environments. | Select when board space permits larger package and thermal performance is secondary to cost. |
| OPA2333AIDGKR | Zero-drift architecture; 0.02 µV/°C drift vs. TLV2462CDGKG4's 2 µV/°C; higher 350 µA/channel supply current. | Better DC stability for long-term sensor calibration; less suitable for battery-constrained designs. | Choose when ultra-low drift dominates over power budget - e.g., laboratory-grade instrumentation. |
Compared with TLV2462IDR, TLV2462CDGKG4 offers 30% smaller PCB area and better thermal performance via DGK package; versus OPA2333AIDGKR, it trades zero-drift precision for 40% lower supply current and proven automotive qualification.

FAQ
What is the operating temperature range for TLV2462CDGKG4?
The TLV2462CDGKG4 is rated for operation from −40°C to +125°C (I-suffix grade), fully qualified to AEC-Q100 standards for automotive applications and validated for industrial control environments. This range is explicitly specified in the "Recommended Operating Conditions" table of the SLOS220J datasheet, with performance parameters guaranteed across the full span.
Does TLV2462CDGKG4 support true rail-to-rail input and output?
Yes, TLV2462CDGKG4 supports true rail-to-rail input (common-mode range extends from GND to VDD) and rail-to-rail output (swing within 100 mV of each rail at 10 mA load). This is confirmed in the device description, electrical characteristics tables (VOH/VOL), and Figure 1–2 showing VIO vs. VICR across the full supply range.
How does the shutdown function work on TLV2462CDGKG4?
The SHDN pin (Pin 5) is active-high: driving it ≥2 V enables normal operation; pulling it ≤0.7 V places both amplifiers into ultralow-power shutdown mode (0.3 µA/channel) and forces outputs into high-impedance state. This behavior is documented in Section "Recommended Operating Conditions" and verified in Figures 22–25 of the SLOS220J datasheet.
What is the maximum capacitive load TLV2462CDGKG4 can drive stably?
TLV2462CDGKG4 maintains stability with up to 160 pF capacitive load at unity gain (AV = 1), achieving 44°–45° phase margin per channel at 3 V and 5 V supplies. This is confirmed in the "Operating Characteristics" table and Figure 36 (Phase Margin vs. Load Capacitance) of the SLOS220J datasheet.
Is TLV2462CDGKG4 pin-compatible with other TLV246x variants?
TLV2462CDGKG4 is pin-compatible with TLV2462IDGKR and TLV2462AIDGKR in the same MSOP-8 (DGK) package, sharing identical pinout (OUT A, IN− A, IN+ A, GND, SHDN, VDD+, IN+ B, IN− B). Pin compatibility is confirmed in the "TLV246x PACKAGE PINOUTS" section (page 4) of the SLOS220J datasheet.
