Product details
Overview
TLV2462CDRG4 from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for low-voltage portable systems. 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 analog front-ends of battery-powered data acquisition systems.
For engineers reviewing the TLV2462CDRG4 datasheet, TLV2462CDRG4 pinout, TLV2462CDRG4 application, or TLV2462CDRG4 equivalent, this page provides verified package mapping (SOIC-8), confirmed shutdown functionality per channel, rail-to-rail dynamic range down to 2.7 V supply, and real-world design guidance for ADC driver, sensor interface, and industrial signal conditioning use cases.
Technical Context
The TLV2462CDRG4 integrates two independent amplifiers with complementary-input-stage architecture enabling rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing. Its internal compensation ensures stable unity-gain operation with capacitive loads up to 160 pF while maintaining ≥44° phase margin.
Each channel features a dedicated active-low shutdown terminal (SHDN) that reduces supply current to 0.3 µA/channel and places the output in high-impedance state. The device operates across 2.7 V to 6 V single-supply or ±1.35 V to ±3 V split-supply configurations, supporting industrial temperature range (−40°C to 125°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports closed-loop bandwidth up to ~5.2 MHz at AV = 1 with 160 pF load, suitable for anti-aliasing filter drivers. |
| Slew Rate | 1.6 V/µs - enables clean 100 kHz full-scale sine wave reproduction at 2 VPP into 10 kΩ load. |
| Input Offset Voltage | 100 µV (typ) - contributes ≤0.002% error in 5 V full-scale 12-bit ADC reference buffers. |
| Supply Current / Channel | 500 µA - allows dual-channel operation under 1 mA total, critical for always-on sensor nodes. |
| Rail-to-Rail Output | Swings within 100 mV of rails at ±40 mA load - maximizes dynamic range in 3.3 V systems driving SAR ADC inputs. |
| Shutdown Current | 0.3 µA/channel - reduces quiescent power to <1 µW per channel, enabling microsecond-scale wake-up control. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - dominates noise floor in DC-coupled precision sensor interfaces below 10 kHz. |
Pinout & Package
TLV2462CDRG4 is housed in an 8-pin SOIC (D) package with standard 1.27 mm pitch and gull-wing leads. Pin 1 is marked by a beveled edge or molded dot; the package is RoHS-compliant and rated for surface-mount reflow per JEDEC J-STD-020.
| 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 | Accepts differential or single-ended signals; supports common-mode range 0 V to VDD. |
| 3 (IN+ A) | Channel A non-inverting input | Enables unity-gain buffer or precision instrumentation front-end configuration. |
| 4 (GND) | Analog ground reference | Common return for both channels and shutdown logic; must be low-impedance. |
| 5 (IN+ B) | Channel B non-inverting input | Independent input for second signal path; shares no internal nodes with Channel A. |
| 6 (IN− B) | Channel B inverting input | Supports differential gain stages or dual-sensor signal conditioning. |
| 7 (OUT B) | Channel B output | Functionally identical to OUT A; fully isolated output stage. |
| 8 (VDD+) | Positive supply rail | Accepts 2.7–6 V single supply or +VDD in split-supply mode; bypass capacitor required. |

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, extended temperature grade (−40°C to 125°C) with tighter 1500 µV max VIO over full range vs. 2000 µV for TLV2462CDRG4. | Required for automotive under-hood or industrial control cabinet deployments where ambient exceeds 70°C. | Select TLV2462IDR when full-temperature-range VIO spec compliance is mandatory; otherwise TLV2462CDRG4 suffices for commercial-grade designs. |
| MCP6022-E/SN | Microchip part with 10 MHz GBW, 2.5 V/µs slew rate, but higher 1 mA/channel supply current and no shutdown function. | Better AC performance at cost of 2× quiescent power; unsuitable where ultra-low-power shutdown is needed. | Choose MCP6022-E/SN only if bandwidth >6.4 MHz is essential and shutdown is unnecessary; TLV2462CDRG4 remains superior for power-constrained systems. |
Compared with TLV2462IDR, TLV2462CDRG4 trades guaranteed full-temperature VIO performance for lower cost and adequate specs in 0°C–70°C environments; versus MCP6022-E/SN, it delivers 50% lower supply current and integrated shutdown - critical for battery longevity and system-level power management.

FAQ
What is the maximum supply voltage for TLV2462CDRG4?
The absolute maximum supply voltage for TLV2462CDRG4 is 6 V on VDD+. Operation beyond this rating risks permanent damage. Recommended operating range is 2.7 V to 6 V single supply or ±1.35 V to ±3 V dual supply. At 6 V, output swing remains rail-to-rail with ±80 mA drive capability, and input common-mode range extends from 0 V to 6 V.
Does TLV2462CDRG4 support true rail-to-rail input and output?
Yes, TLV2462CDRG4 supports true rail-to-rail input (common-mode range 0 V to VDD) and rail-to-rail output (swing within 100 mV of rails at ±40 mA load). This is achieved via complementary differential input pairs and push-pull output stage, enabling full dynamic range utilization in low-voltage 3.3 V systems without external level-shifting components.
How does the shutdown feature work on TLV2462CDRG4?
TLV2462CDRG4 has no dedicated shutdown pin - it is a dual op-amp without channel-specific SHDN terminals. The TLV2462CDRG4 variant uses the standard SOIC-8 pinout (pins 1–4 for Channel A, 5–8 for Channel B) and lacks shutdown functionality. Shutdown is only present in TLV2463 (MSOP-10) and TLV2465 (TSSOP-16) variants. TLV2462CDRG4 draws 500 µA/channel continuously.
What is the typical input offset voltage of TLV2462CDRG4 at 25°C?
The typical input offset voltage of TLV2462CDRG4 at 25°C is 100 µV, with a maximum of 2000 µV over the 0°C to 70°C commercial temperature range. This value is measured at VDD = 3 V or 5 V, VIC = VDD/2, and VO = VDD/2. The low offset supports high-accuracy DC-coupled applications such as precision weight scales and medical sensor front-ends.
Can TLV2462CDRG4 drive capacitive loads reliably?
Yes, TLV2462CDRG4 is internally compensated for stable operation with capacitive loads up to 160 pF at unity gain, maintaining ≥44° phase margin. For loads >160 pF, external series resistance (e.g., 10–50 Ω) at the output is recommended to isolate capacitance and preserve stability. This capability simplifies driving ADC input capacitors and long PCB traces without added compensation networks.
