Product details
Overview
TLV2462AID from Texas Instruments is a dual, rail-to-rail input/output operational amplifier optimized for low-power portable and automotive 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 at 2.7–6 V supply.
For engineers reviewing the TLV2462AID datasheet, TLV2462AID pinout, TLV2462AID application, or TLV2462AID equivalent, this device is selected for precision analog signal conditioning where rail-to-rail swing, low quiescent current, and extended temperature operation (−40°C to 125°C) are critical in battery-powered instrumentation and automotive control modules.
Technical Context
The TLV2462AID integrates two independent amplifiers with complementary-input-stage architecture enabling true 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 an active shutdown terminal (SHDN) that reduces supply current to 0.3 µA/channel and places the output in high-impedance state - supporting power-gating in multi-stage analog signal chains without external isolation circuitry.
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 minimal phase loss. |
| Slew Rate | 1.6 V/µs - enables accurate reproduction of 100-kHz full-scale sine waves at 2-Vpp without slew-induced distortion. |
| Supply Current per Channel | 500 µA - allows continuous operation in always-on sensor nodes powered by coin cells or energy harvesters. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.002% gain error in 5-V full-scale 12-bit ADC driver applications. |
| 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 systems. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% versus active mode, critical for duty-cycled measurement systems. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive and industrial motor-control environments without derating. |
Pinout & Package
TLV2462AID is housed in an 8-pin SOIC (D) package with exposed pad for thermal enhancement, compatible with standard PCB assembly processes and rated for 125°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers rail-to-rail buffered signal; capable of sourcing/sinking ±80 mA into resistive loads. |
| 2 (IN− A) | Channel A inverting input | Differential input node with 1.3 nA bias current (typ) and 10⁹ Ω differential resistance. |
| 3 (IN+ A) | Channel A non-inverting input | Supports common-mode voltages from GND to VDD; enables single-supply sensor interfacing. |
| 4 (GND) | Analog ground reference | Primary return path for both channels; must be low-impedance to minimize PSRR degradation. |
| 5 (IN+ B) | Channel B non-inverting input | Independent input for second amplifier; shares same rail-to-rail input range as Channel A. |
| 6 (IN− B) | Channel B inverting input | Matches Channel A's input characteristics; supports matched dual-channel configurations. |
| 7 (OUT B) | Channel B output | Functionally identical to OUT A; enables dual-path signal processing without cross-talk. |
| 8 (VDD+) | Positive supply rail | Accepts 2.7–6 V DC; internal regulation maintains performance across full voltage range. |

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 |
|---|---|---|---|
| TLV2462CD | Same core architecture but rated only for 0°C to 70°C; 2000 µV max VIO vs. 1500 µV for TLV2462AID. | Limited to commercial-grade consumer electronics; unsuitable for automotive or industrial ambient conditions. | Select TLV2462CD only for cost-sensitive, non-temperature-critical designs where extended qualification is unnecessary. |
| OPA2340UA | Higher 10-MHz GBW and lower 7-nV/√Hz noise, but 1.3-mA/channel supply current and no shutdown function. | Better AC performance at expense of >2× quiescent power; lacks power-gating capability for ultra-low-power systems. | Choose OPA2340UA when bandwidth and noise dominate over power budget, and shutdown is not required. |
Compared with TLV2462CD, TLV2462AID provides guaranteed 1500 µV VIO max and full automotive temperature support, while OPA2340UA trades 2.6× higher supply current for improved noise and speed - making TLV2462AID optimal for thermally demanding, battery-constrained dual-channel analog front-ends.

FAQ
What is the maximum supply voltage rating for TLV2462AID?
The absolute maximum supply voltage for TLV2462AID is 6 V. Operation beyond this limit risks permanent damage. The device is fully specified from 2.7 V to 6 V, with consistent rail-to-rail input/output performance and 6.4-MHz gain-bandwidth product across this range. At 6 V, output swing remains within 100 mV of each rail at 10-mA load, preserving dynamic range in high-voltage single-supply systems.
Does TLV2462AID include a shutdown feature, and how is it controlled?
Yes, TLV2462AID includes an active-low shutdown terminal (pin 5 on SOIC-D package). Driving SHDN below 0.7 V places both amplifiers in ultralow-power mode with 0.3 µA/channel supply current and high-impedance outputs. Pulling SHDN above 2 V enables normal operation. This pin is internally biased and requires no external pull-up; logic-level control from MCU GPIO suffices for precise power sequencing.
What is the input offset voltage specification for TLV2462AID over temperature?
TLV2462AID has a maximum input offset voltage of 1500 µV over its full operating range of −40°C to 125°C, with typical value of 500 µV at 25°C. Its temperature coefficient is 2 µV/°C, meaning offset drift contributes ≤300 µV over a 150°C span. This stability supports uncalibrated 12-bit measurements in automotive and industrial environments without trimming.
Can TLV2462AID drive capacitive loads, and what is the recommended compensation?
TLV2462AID is stable with capacitive loads up to 160 pF in unity-gain configuration, as verified by ≥44° phase margin. For loads exceeding 100 pF, TI recommends adding a small series resistor (10–50 Ω) between amplifier output and capacitor to isolate reactive feedback. No external compensation capacitor is required for standard PCB traces or typical ADC input capacitance (≤20 pF), simplifying layout in space-constrained designs.
How does TLV2462AID perform in single-supply sensor interface applications?
TLV2462AID excels in single-supply sensor interfaces due to its rail-to-rail input (0 V to VDD) and output (within 100 mV of rails at 10 mA) capability. When powered from 3.3 V, it resolves full-scale 0–3.3 V signals with <0.003% gain error from offset and <0.01% THD+N at 10-kHz - enabling direct connection to precision ADCs without level-shifting or external bias networks.
