Product details
Overview
TLV2460QDR from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier with shutdown capability, designed for automotive and industrial 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 - enabling high-fidelity analog buffering in low-voltage systems such as automotive sensor signal conditioning.
For engineers reviewing the TLV2460QDR datasheet, TLV2460QDR pinout, TLV2460QDR application, or TLV2460QDR equivalent, key selection criteria include its Q-temp automotive qualification (−40°C to 125°C), micropower shutdown mode (0.3 µA/channel), SOT-23-6 packaging, rail-to-rail output swing, and compatibility with ADC driver and precision sensor interface designs.
Technical Context
The TLV2460QDR implements a CMOS input stage with rail-to-rail common-mode input range extending beyond supply rails, supporting dynamic range maximization in 2.7–6 V single-supply systems. Its output stage delivers true rail-to-rail swing with ±80 mA sourcing/sinking capability at 1 V from rail, overcoming limitations of earlier rail-to-rail amplifiers.
It integrates an active shutdown terminal (SHDN) that reduces supply current to 0.3 µA per channel while placing the output in high-impedance state - critical for power-gated signal chains in automotive body control modules and battery-powered industrial sensors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable unity-gain buffer operation up to ~6 MHz with minimal phase margin degradation. |
| Slew Rate | 1.6 V/µs - supports fast settling for 12-bit ADC sampling at ≥100 kSPS without distortion. |
| Input Offset Voltage | 100 µV - ensures ≤0.0025% gain error in 4 V full-scale precision sensor interfaces. |
| Supply Current | 500 µA/channel - allows continuous operation in always-on automotive subsystems with <1 mW total dissipation at 3 V. |
| Output Drive | ±80 mA - drives 50 Ω loads directly or interfaces with multiple downstream logic inputs without external buffers. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% versus active mode, meeting ISO 16750-2 quiescent current requirements. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - preserves SNR in low-level thermocouple or strain gauge front-ends. |
Pinout & Package
TLV2460QDR is packaged in a 6-pin SOT-23 (DBV) package with tape-and-reel delivery (R suffix). The device features a standard pinout optimized for high-density PCB layouts and automotive thermal cycling reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing with ±80 mA drive; connects directly to ADC input or transducer load. |
| 2 (GND) | Analog ground reference | Primary return path for input bias and output current; must be tied to clean system AGND plane. |
| 3 (IN+) | Non-inverting input | CMOS input with 1.3 nA bias current; accepts signals from 0 V to VDD with no phase reversal. |
| 4 (VDD+) | Positive supply | Operates from 2.7 V to 6 V; supports single-supply automotive battery monitoring (4.5–5.5 V) and low-voltage IoT sensors (3.3 V). |
| 5 (IN−) | Inverting input | Differential input node for closed-loop configurations; matched to IN+ for <2 µV offset drift over temperature. |
| 6 (SHDN) | Active-high shutdown control | Drives output to high-Z when <0.7 V; enables microcontroller-controlled power gating in sleep/wake cycles. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full 0–VDD signal swing at both input and output, maximizing dynamic range in 3.3 V systems without level-shifting. |

| High-output-drive capability | ±80 mA output current allows direct driving of capacitive loads (e.g., 1000 pF ADC input) or resistive networks without stability compromise. |
| Low input offset voltage | 100 µV max ensures sub-0.01% gain error in precision current-sense amplifiers used in automotive motor control feedback loops. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461QDR | Dual-channel version in same SOT-23-6 package; identical electrical specs per channel but shares supply and shutdown pins. | Requires dual-amplifier topology (e.g., signal + reference path); not suitable for space-constrained single-channel designs. | Select TLV2461QDR only when dual-channel functionality is required and board layout accommodates shared SHDN control. |
| OPA333AQDBVR | Zero-drift architecture; 10 µV max offset, 0.1 µV/°C drift, but lower 350 kHz GBW and no shutdown pin. | Better DC precision for static measurements; unsuitable for AC-coupled or fast-settling applications requiring >1 MHz bandwidth. | Choose OPA333AQDBVR for ultra-low-offset DC sensing; retain TLV2460QDR for mixed-signal buffering with shutdown and speed. |
Compared with TLV2461QDR, TLV2460QDR saves board area and simplifies routing in single-amplifier roles; compared with OPA333AQDBVR, it trades offset precision for higher bandwidth, output drive, and integrated shutdown - making TLV2460QDR optimal for automotive signal chains demanding speed, robustness, and power gating.

FAQ
What is the operating temperature range for TLV2460QDR?
The TLV2460QDR is qualified for the automotive Q-temp range of −40°C to 125°C ambient temperature, meeting AEC-Q100 requirements for under-hood and chassis-mounted electronic control units. This rating is explicitly confirmed in the TI datasheet SLOS220J for the Q-suffix variant, ensuring guaranteed performance across the full range without derating.
Does TLV2460QDR support single-supply operation?
Yes, TLV2460QDR supports true single-supply operation from 2.7 V to 6 V. Its rail-to-rail input common-mode range extends from 0 V to VDD, and its output swings within 10 mV of each rail under light load - enabling direct interfacing with 3.3 V or 5 V microcontrollers and ADCs without level-shifting circuitry.
What is the function of the SHDN pin on TLV2460QDR?
The SHDN pin on TLV2460QDR is an active-high digital control input. When driven above 2 V, the amplifier operates normally; when pulled below 0.7 V, it enters ultralow-power shutdown mode drawing only 0.3 µA per channel while placing the output in high-impedance state - essential for power-gated sensor interfaces in automotive and battery-powered systems.
Is TLV2460QDR pin-compatible with other TLV246x variants?
TLV2460QDR uses the 6-pin SOT-23 (DBV) package with standardized pinout (OUT, GND, IN+, VDD+, IN−, SHDN). It is pin-compatible with TLV2460CDR, TLV2460IDR, and TLV2460AIDR - all sharing identical DBV pin mapping. However, dual-channel TLV2461QDR uses the same package but different pin assignment (e.g., second output on pin 1), so cross-replacement requires schematic verification.
What is the maximum output current specification for TLV2460QDR?
TLV2460QDR delivers ±80 mA output current when measured 1 V from either rail (VOH ≥ VDD − 1 V, VOL ≤ 0 + 1 V) at VDD = 5 V, as specified in the "Electrical Characteristics" table of the SLOS220J datasheet. This high drive capability supports direct connection to moderate capacitive loads or multiple logic inputs without external buffers.
