Product details
Overview
TLV2460QD from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier with shutdown, designed for high-reliability automotive applications. 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.
For engineers reviewing the TLV2460QD datasheet, TLV2460QD pinout, TLV2460QD application, or TLV2460QD equivalent, key selection criteria include its Q-temp automotive qualification, micropower shutdown mode (0.3 µA/channel), rail-to-rail dynamic range in low-voltage systems, and suitability for ADC buffering and sensor signal conditioning in harsh environments.
Technical Context
The TLV2460QD implements a CMOS input stage enabling rail-to-rail common-mode input voltage range (0 V to VDD) and rail-to-rail output swing, supporting full dynamic range in 2.7–6 V single-supply systems. Its internal architecture integrates a dedicated shutdown control path that places the output in high-impedance state while reducing supply current to 0.3 µA/channel.
It achieves 6.4 MHz unity-gain bandwidth and 1.6 V/µs slew rate at 5 V supply with only 500 µA quiescent current per channel, balancing ac performance and power efficiency. Input noise voltage is specified at 11 nV/√Hz (1 kHz), and input offset voltage is 100 µV (typical) over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable unity-gain operation up to ~6 MHz with adequate phase margin for precision signal amplification. |
| Slew Rate | 1.6 V/µs - supports clean 100 kHz full-scale output slewing for 12-bit ADC drivers without distortion. |
| Supply Current (Active) | 500 µA/channel - allows battery-powered automotive sensors to operate >1 year on coin-cell energy budgets. |
| Supply Current (Shutdown) | 0.3 µA/channel - reduces system standby power to negligible levels during vehicle sleep modes. |
| Input Offset Voltage | 100 µV (typ) - ensures <0.002% gain error in 5 V full-scale instrumentation front-ends. |
| Rail-to-Rail I/O | Input: 0 V to VDD; Output: within 100 mV of rails - maximizes usable signal swing in 3.3 V microcontroller interfaces. |
| Output Drive | ±80 mA - directly drives 50 Ω transmission lines or multiple logic inputs without external buffers. |
Pinout & Package
TLV2460QD is packaged in an 8-pin small-outline integrated circuit (SOIC) package (D package), qualified for automotive temperature range (−40°C to 125°C) and available taped and reeled (TLV2460QDR).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused pad; must remain unconnected or grounded per layout guidelines to avoid parasitic coupling. |
| 2 (IN−) | Inverting input | Differential node for feedback networks; high-impedance CMOS input (1.3 nA bias current @ 5 V). |
| 3 (IN+) | Non-inverting input | Reference or signal input node; supports rail-to-rail common-mode range (0 V to VDD). |
| 4 (GND) | Analog ground | Primary return path for input bias currents and output load; requires low-impedance PCB plane tie. |
| 5 (SHDN) | Shutdown control | Active-high digital input; ≥2 V enables operation, ≤0.7 V enters ultralow-power shutdown (0.3 µA). |
| 6 (VDD+) | Positive supply | Single-supply pin (2.7–6 V); decoupling capacitor (0.1 µF) required within 5 mm of pin. |
| 7 (OUT) | Amplifier output | Capable of ±80 mA sourcing/sinking; rail-to-rail swing enables direct interface to SAR ADC reference buffers. |
| 8 (NC) | No internal connection | Unused pad; electrically isolated; no routing or thermal relief required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3 V supply in automotive body control modules without level-shifting components. |
| Micropower shutdown mode | Reduces total system quiescent current by >99.9% during vehicle ignition-off states, extending battery life. |
| Q-temp automotive qualification | Guarantees operation from −40°C to 125°C with AEC-Q100 stress test compliance for under-hood deployment. |
| 6.4 MHz bandwidth at 500 µA | Delivers higher speed than competing micropower op-amps (e.g., TLV245x), enabling faster sensor response in ADAS subsystems. |
| High-output-drive capability | Drives 10 kΩ loads to rail with <0.2 V drop and sustains ±80 mA-eliminates need for discrete output transistors in actuator interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461QD | Dual-channel version in same SOIC-8 package; identical electrical specs per channel but shares supply and shutdown pins. | Requires dual-amplifier topology (e.g., composite filter + buffer); not suitable for space-constrained single-channel designs. | Select TLV2461QD only when two matched amplifiers are needed in same footprint and thermal environment. |
| OPA333AQDGKR | Zero-drift architecture; 10 µV max offset, 0.1 µV/°C drift, but 350 µA supply current and no shutdown pin. | Better dc accuracy for precision weigh scales; lacks shutdown and automotive temp rating (only −40°C to 125°C industrial grade). | Choose OPA333AQDGKR only when offset drift dominates system error budget and shutdown is unnecessary. |
Compared with TLV2461QD, TLV2460QD saves board area and simplifies layout in single-amplifier nodes; compared with OPA333AQDGKR, TLV2460QD provides guaranteed shutdown control and AEC-Q100 qualification for automotive safety-critical functions.

FAQ
What is the operating temperature range for TLV2460QD?
The TLV2460QD is qualified for the automotive temperature range of −40°C to 125°C, meeting AEC-Q100 Grade 2 requirements. This specification is explicitly confirmed in the TI datasheet SLOS220J for the Q-suffix variant, and applies to all package options including the SOIC-8 (D) package used by TLV2460QD.
Does TLV2460QD support rail-to-rail input and output operation?
Yes, TLV2460QD supports true rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swing within 100 mV of supply rails under load). This capability is documented in the device description, electrical characteristics tables, and typical performance curves of the official TI datasheet SLOS220J.
What is the shutdown current consumption of TLV2460QD?
The TLV2460QD draws 0.3 µA per channel in shutdown mode when the SHDN pin is held ≤0.7 V, as specified in the "Electrical Characteristics" table of the TI datasheet SLOS220J. This ultralow current enables extended battery life in automotive sleep-mode applications.
Is TLV2460QD pin-compatible with other TLV246x variants in SOIC-8?
No-TLV2460QD uses an 8-pin SOIC (D) package with two NC pins (pins 1 and 8), whereas TLV2461QD (dual) and TLV2462QD (dual with independent shutdown) use different pinouts in the same package. Pin compatibility is not claimed in the datasheet; each variant has unique pin assignments verified in the "Package Pinouts" section of SLOS220J.
What are the absolute maximum supply voltage limits for TLV2460QD?
The absolute maximum supply voltage for TLV2460QD is 6 V, as stated in the "Absolute Maximum Ratings" table of the TI datasheet SLOS2460QD. Exceeding this voltage risks permanent damage, and operation above 6 V is not supported-even transiently-under any condition.
