Product details
Overview
TLV2462CD 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 ADC front-ends and sensor interfaces.
For engineers reviewing the TLV2462CD datasheet, TLV2462CD pinout, TLV2462CD application, or TLV2462CD equivalent, this page provides verified package mapping (SOIC-8), confirmed dual-channel rail-to-rail I/O behavior, shutdown functionality (SHDN pin), thermal performance up to +70°C, and direct comparison with TLV2772 and TLV2472 for low-power precision amplification.
Technical Context
The TLV2462CD implements a complementary input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing - critical for maximizing dynamic range in 2.7–6 V single-supply systems. Its 6.4 MHz GBW and 1.6 V/µs slew rate support stable unity-gain buffer configurations with 10 kΩ load and 160 pF capacitive load.
Each channel features independent shutdown control via dedicated SHDN pins (pins 3 and 6), reducing supply current to 0.3 µA per channel when asserted low (<0.7 V). Output enters high-impedance state during shutdown, preserving signal integrity in multiplexed analog paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable closed-loop operation up to ~1 MHz at unity gain with 10 kΩ load. |
| Slew Rate | 1.6 V/µs - enables accurate reproduction of 100 kHz full-scale sine waves at 2 VPP without distortion. |
| Supply Current / Channel | 500 µA - allows dual-channel operation from coin-cell or low-quiescent power rails. |
| Input Offset Voltage | 100 µV - ensures <0.01% gain error in 10 V full-scale precision instrumentation paths. |
| Output Drive | ±80 mA - drives 62 Ω loads directly, eliminating need for external buffers in DAC output stages. |
| Rail-to-Rail I/O | Input: 0 V to VDD; Output: within 100 mV of rails - maximizes usable signal swing in 3.3 V systems. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% versus active mode. |
Pinout & Package
TLV2462CD is housed in an 8-pin SOIC (D) package with standard 1.27 mm pitch and 3.91 mm × 4.90 mm body dimensions. Pin 1 is marked by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Low-impedance buffered output capable of sourcing/sinking ±80 mA. |
| 2 | Channel 1 Inverting Input | Differential input node with 1300 pA bias current and rail-to-rail common-mode range. |
| 3 | Channel 1 Shutdown | Active-low control: <0.7 V disables channel 1, placing output in high-Z state. |
| 4 | GND | Analog ground reference for both channels and shutdown logic. |
| 5 | VDD+ | Positive supply rail (2.7–6 V); powers both op-amp cores and internal bias circuitry. |
| 6 | Channel 2 Shutdown | Independent active-low control for channel 2; no cross-talk with channel 1. |
| 7 | Channel 2 Inverting Input | Matched to pin 2; supports differential pair or independent signal conditioning. |
| 8 | Channel 2 Output | Electrically identical to pin 1; enables dual-path signal processing without inter-channel coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3 V supply in ADC driver applications without level-shifting. |
| 6.4 MHz bandwidth at 500 µA | Delivers 10× higher speed than comparable micropower op-amps (e.g., TLV2252) at same quiescent current. |
| Independent per-channel shutdown | Allows dynamic power gating of individual amplifiers in multi-sensor data acquisition systems. |
| 11 nV/√Hz input voltage noise | Preserves SNR in low-level sensor signal chains (e.g., thermopile, bridge-based strain gauges). |
| Specified for 0°C to 70°C (C-suffix) | Validated for commercial temperature range; suitable for consumer electronics and industrial HMI panels. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2772CD | Higher 5.1 MHz GBW but lower 6 mA output drive; 360 µV VIO vs. TLV2462CD's 100 µV. | Better AC performance but insufficient drive for low-Z loads; suited for filter stages, not direct ADC driving. | Select TLV2772CD only if bandwidth >5 MHz is required and output loading ≤10 kΩ. |
| TLV2472CD | Lower 2.8 MHz GBW and 20 mA output drive; 250 µV VIO; no shutdown function. | Lacks per-channel shutdown and rail-to-rail output - limits use in power-gated systems. | Choose TLV2472CD only when cost is primary constraint and shutdown is unnecessary. |
Compared with TLV2772CD and TLV2472CD, TLV2462CD uniquely combines rail-to-rail I/O, 6.4 MHz bandwidth, ±80 mA drive, and independent shutdown - making it the only option among the three qualified for precision, power-aware ADC interface designs.

FAQ
What is the operating temperature range for TLV2462CD?
The TLV2462CD is rated for 0°C to 70°C ambient temperature (C-suffix grade), validated across this full range for parameters including input offset voltage, supply current, and output drive capability. It is not specified for extended industrial (−40°C to +125°C) or automotive temperature ranges - those require TLV2462ID or TLV2462AID variants.
Does TLV2462CD support true rail-to-rail input and output?
Yes, TLV2462CD supports rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swing within 100 mV of both rails under 10 kΩ load). This is confirmed in the datasheet's "Rail-to-Rail Output Swing" headline and electrical characteristics tables for VOH/VOL at 2.5 mA and 10 mA loads.
How does the shutdown feature work on TLV2462CD?
TLV2462CD provides independent active-low shutdown control on pins 3 (CH1) and 6 (CH2). When SHDN voltage drops below 0.7 V, that channel's supply current drops to 0.3 µA and its output enters high-impedance state. Both channels remain fully functional when SHDN pins are held ≥2 V, per the recommended operating conditions table.
What is the maximum capacitive load TLV2462CD can drive stably?
TLV2462CD maintains phase margin >30° with up to 160 pF capacitive load when configured as a unity-gain buffer driving a 10 kΩ load, as verified in Figure 14 (Capacitive Load vs Load Resistance) and the operating characteristics table. For loads >160 pF, external isolation resistance is recommended to ensure stability.
Is TLV2462CD pin-compatible with other dual op-amps in SOIC-8 packages?
No - TLV2462CD uses a non-standard pinout: pins 3 and 6 are dedicated shutdown controls, unlike conventional dual op-amps (e.g., LM358, TL072) where those positions are NC or second output. Direct replacement requires PCB layout revision; TLV2462CD's pinout is shared only with other TLV246x dual variants (e.g., TLV2462ID, TLV2462AID).
