Product details
Overview
TLV2462QD from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier designed for automotive and industrial signal conditioning. 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 across −40°C to 125°C. It buffers ADC inputs in battery-powered engine control units.
For engineers reviewing the TLV2462QD datasheet, TLV2462QD pinout, TLV2462QD application, or TLV2462QD equivalent, this page provides verified package mapping (SOIC-8), confirmed shutdown functionality, temperature-rated performance data, and direct alternatives for Q-temp automotive designs requiring rail-to-rail dynamic range and low quiescent power.
Technical Context
The TLV2462QD implements a CMOS input stage enabling rail-to-rail common-mode input voltage range (0 V to VDD) and rail-to-rail output swing. Its architecture supports high-output-drive capability (±80 mA) while maintaining micropower operation (500 µA/channel) and low noise (11 nV/√Hz at 1 kHz).
It integrates an active shutdown terminal that reduces supply current to 0.3 µA per channel and places the output in high-impedance state. The device is qualified to AEC-Q100 Grade 1 (−40°C to 125°C) and specified with 1500 µV max input offset voltage over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V single supply - enables operation from Li-ion battery (3.0–3.7 V) or 5 V rail without level shifting. |
| Gain-Bandwidth Product | 6.4 MHz - supports stable unity-gain buffer configurations up to ~5 MHz with 10 kΩ load and 160 pF capacitance. |
| Slew Rate | 1.6 V/µs - allows clean 1 VPP signals up to ~800 kHz before slew-induced distortion dominates. |
| Input Offset Voltage | 100 µV (typ), 1500 µV (max over −40°C to 125°C) - ensures <0.03% gain error in 3.3 V sensor front-ends. |
| Output Drive | ±80 mA - drives 37.5 Ω loads to rails, sufficient for driving SAR ADC reference buffers or analog multiplexer outputs. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% vs active mode, critical for always-on vehicle modules. |
| Input Noise Voltage | 11 nV/√Hz at 1 kHz - maintains SNR >85 dB for 100 Hz–10 kHz sensor signals with 10 kΩ source impedance. |
Pinout & Package
TLV2462QD is housed in an 8-pin SOIC (D) package with standard 1.27 mm pitch, 3.91 mm × 4.90 mm body, and exposed pad not present. Pin 1 is marked by beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output; rail-to-rail swing supports full-scale ADC input buffering. |
| 2 | IN− A | Inverting input; high-impedance CMOS node accepts precision feedback networks. |
| 3 | IN+ A | Non-inverting input; extends to both supply rails for maximum dynamic range in low-voltage systems. |
| 4 | GND | Analog ground reference; must be star-connected to minimize noise coupling in mixed-signal PCBs. |
| 5 | SHDN | Active-high shutdown control; ≥2 V enables, ≤0.7 V disables amplifier and forces high-Z output. |
| 6 | VDD+ | Positive supply rail; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin. |
| 7 | OUT B | Second amplifier output; independent channel enables dual-sensor conditioning or signal splitting. |
| 8 | IN− B | Inverting input for Channel B; electrically isolated from Channel A except via shared supply and ground. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 0–3.3 V or 0–5 V ADC input ranges without external level-shifting circuitry. |
| Micropower shutdown mode | Reduces total system quiescent current to sub-µA levels during sleep cycles in telematics or ADAS modules. |
| Automotive-grade qualification | AEC-Q100 Grade 1 certified for use in engine control, transmission, and body electronics without derating. |
| High output drive (±80 mA) | Drives capacitive loads up to 1000 pF directly, eliminating need for external buffer stages in sensor interfaces. |
| Low input offset drift | 2 µV/°C max tempco ensures <150 µV offset shift over −40°C to 125°C, critical for uncalibrated temperature sensors. |
Applications
| Engine Control Unit (ECU) Sensor Interface | Automotive Cabin Temperature Monitoring |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Same silicon, identical electrical specs, but rated for −40°C to 125°C (I-suffix) and packaged in tape-and-reel SOIC-8. | Not qualified to AEC-Q100; intended for industrial, not automotive, applications. | Select TLV2462IDR only if AEC-Q100 certification is not required and cost optimization is prioritized. |
| LM7332QMA/NOPB | Higher supply current (1.3 mA/ch), higher slew rate (10 V/µs), no shutdown, wider supply (2.7–36 V), AEC-Q100 Grade 1. | Designed for high-speed, high-voltage industrial motor control-not optimized for micropower or low-noise sensor buffering. | Choose LM7332QMA/NOPB when driving heavy capacitive loads (>1 nF) or requiring >10 MHz bandwidth at higher supply voltages. |
Compared with TLV2462QD, TLV2462IDR offers identical performance without automotive qualification, while LM7332QMA/NOPB trades micropower for speed and voltage range-making TLV2462QD optimal for battery-sensitive, low-noise, rail-to-rail signal conditioning in qualified automotive systems.

FAQ
What is the operating temperature range for TLV2462QD?
The TLV2462QD is rated for −40°C to 125°C free-air temperature (TA), meeting AEC-Q100 Grade 1 requirements for automotive under-hood and cabin applications. This range is explicitly defined in the "Recommended Operating Conditions" table of the SLOS220J datasheet and applies to all electrical specifications unless otherwise noted.
Does TLV2462QD include a shutdown feature, and how is it controlled?
Yes, TLV2462QD includes an active-high shutdown terminal (Pin 5). Driving SHDN ≥2 V enables normal operation; pulling SHDN ≤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 confirmed in the Electrical Characteristics tables for IDD(SHDN) and is consistent across the TLV2460/3/5 variants.
What package type is used for TLV2462QD, and is it lead-free?
TLV2462QD uses the SOIC-8 (D) package, 3.91 mm × 4.90 mm body, 1.27 mm lead pitch. Per TI's packaging documentation and Pb-Free Conversion Notices, the Q-suffix devices-including TLV2462QD-are manufactured in RoHS-compliant, lead-free terminations and meet JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3).
How does TLV2462QD perform in rail-to-rail input operation?
TLV2462QD's CMOS input stage allows the common-mode input voltage range to extend 200 mV beyond both supply rails (0 V to VDD), enabling full dynamic range utilization in low-voltage systems. This is verified in Figure 1 and 2 of the datasheet, showing input offset voltage remains stable across VICR = −0.2 V to VDD + 0.2 V at 3 V and 5 V supplies.
What is the maximum capacitive load TLV2462QD can drive stably?
TLV2462QD maintains phase margin >30° with up to 1000 pF capacitive load when driving a 10 kΩ resistive load, as shown in Figure 14 ("Capacitive Load vs Load Resistance"). For unity-gain stable operation with heavier loads, a series resistor (≥10 Ω) between output and capacitance is recommended to isolate reactive feedback.
