Product details
Overview
TLV2460QPWRQ1 from Texas Instruments is a single-channel, automotive-grade rail-to-rail input/output operational amplifier with shutdown control, 6.4-MHz gain-bandwidth product, 1.6-V/μs slew rate, 500-μA supply current per channel, and 100-μV input offset voltage. It operates from 2.7 V to 6 V and is used in HEV/EV battery management systems for precision signal conditioning before ADC buffering.
For engineers reviewing the TLV2460QPWRQ1 datasheet, TLV2460QPWRQ1 pinout, TLV2460QPWRQ1 application, or TLV2460QPWRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (–40°C to +125°C), micropower shutdown mode (0.3 μA/channel), rail-to-rail output swing, ±80-mA output drive capability, and low 11-nV/√Hz input noise voltage.
Technical Context
The TLV2460QPWRQ1 implements a CMOS input stage enabling rail-to-rail common-mode input range beyond supply rails and rail-to-rail output swing with high-output-drive capability. Its internal architecture supports stable operation with capacitive loads up to 160 pF and maintains ≥44° phase margin at unity gain with 10-kΩ load and 160-pF capacitance.
It features an active-low shutdown terminal (SHDN) that reduces supply current to 0.3 μA/channel while placing the output in high-impedance state. The device delivers 6.4-MHz bandwidth and 1.6-V/μs slew rate at 5 V supply, with THD+N as low as 0.004% at 10-kHz, 4-VPP output under 10-kΩ load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 6.4 MHz - Enables stable closed-loop operation up to ~1 MHz with moderate gain, suitable for sensor signal amplification and anti-aliasing filtering. |
| Slew rate | 1.6 V/μs - Supports clean reproduction of 100-kHz, 1-VPP signals without distortion in buffer or driver configurations. |
| Input offset voltage | 100 μV (typ, 25°C) - Ensures ≤0.004% error in 2.5-V reference-based measurement paths, critical for battery cell voltage monitoring. |
| Supply current per channel | 500 μA (typ, 3 V) - Enables multi-channel analog front-ends in power-constrained automotive modules without thermal penalty. |
| Shutdown current | 0.3 μA (typ, 25°C) - Allows deep sleep modes in always-on vehicle subsystems while retaining fast wake-up (<8 μs turn-on time). |
| Output drive | ±80 mA - Drives 50-Ω cables or multiple 10-kΩ ADC inputs directly, eliminating need for external buffers in distributed sensing nodes. |
| Input noise voltage | 11 nV/√Hz (1 kHz) - Maintains SNR > 90 dB in 10-kHz bandwidth applications such as motor current shunt amplification. |
Pinout & Package
TLV2460QPWRQ1 is packaged in an 8-pin TSSOP (PW) with nominal body size 4.40 mm × 3.00 mm, optimized for space-constrained automotive PCB layouts and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN− (Pin 2) | Inverting input | Accepts differential or inverting configuration signals; supports common-mode range from –0.2 V to VDD + 0.2 V. |
| IN+ (Pin 3) | Noninverting input | Enables unity-gain buffer or precision instrumentation amplifier front-end with rail-to-rail input capability. |
| OUT (Pin 6) | Amplifier output | Delivers rail-to-rail swing (within 100 mV of rails at ±80 mA) and remains high-impedance during shutdown. |
| GND (Pin 4) | Negative supply | Reference node for single-supply operation; must be low-impedance to minimize PSRR degradation. |
| VDD+ (Pin 7) | Positive supply | Accepts 2.7 V to 6 V; supplies both amplifier core and shutdown logic; decoupling required within 1 cm. |
| SHDN (Pin 8) | Shutdown control | Active-low digital input; <0.7 V enables ultralow-current mode; >2 V enables normal operation. |
| NC (Pins 1, 5) | No internal connection | Not bonded; must be left floating or tied to GND for mechanical stability-no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode extends 0.2 V beyond rails; output swings within 100 mV of rails at full load-maximizes dynamic range in 3.3-V or 5-V automotive systems. |
| AEC-Q100 Grade 1 | Qualified for –40°C to +125°C ambient operation with HBM ESD ≥2000 V and CDM ≥1000 V-meets functional safety requirements for powertrain and body control units. |
| Micropower shutdown | Reduces IDD to 0.3 μA/channel while isolating output-enables periodic wake-up sampling in battery-supplied telematics modules without leakage-induced drain. |
| High-output-drive capability | ±80-mA sourcing/sinking ensures stable driving of 10-kΩ ADC inputs or 50-Ω transmission lines-eliminates need for secondary drivers in compact ECUs. |
| Low input noise | 11 nV/√Hz at 1 kHz enables accurate amplification of µV-level signals from thermocouples or current-sense shunts in motor control inverters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461QPWRQ1 | Single-channel, same pinout and specs, but lacks shutdown terminal (SHDN pin omitted); identical GBW, slew rate, and offset. | Used where continuous operation is required and system-level power gating replaces per-amplifier shutdown. | Select when board layout cannot accommodate SHDN routing or when centralized power control suffices. |
| LMV321Q1MG/NOPB | Lower GBW (1 MHz), no shutdown, higher input offset (250 μV max), but lower cost and wider supply range (2.7 V to 5.5 V). | Suitable for non-critical signal paths like cabin lighting dimming or HVAC sensor interfaces where precision is secondary. | Choose for cost-sensitive, non-safety-critical body electronics where 6.4-MHz bandwidth and 100-μV offset are not required. |
Compared with TLV2461QPWRQ1 and LMV321Q1MG/NOPB, the TLV2460QPWRQ1 uniquely combines AEC-Q100 Grade 1 qualification, micropower shutdown, and 6.4-MHz bandwidth in a single-channel TSSOP package-making it optimal for safety-aware, power-gated automotive sensing nodes requiring high fidelity and fast wake-up.

FAQ
What is the operating temperature range for TLV2460QPWRQ1?
The TLV2460QPWRQ1 is qualified per AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. This rating applies across all electrical specifications in the datasheet, including input offset voltage, supply current, and gain-bandwidth product-ensuring reliability in engine bay and powertrain environments where the TLV2460QPWRQ1 is commonly deployed.
Does TLV2460QPWRQ1 support rail-to-rail input and output simultaneously?
Yes, the TLV2460QPWRQ1 supports rail-to-rail input common-mode range (–0.2 V to VDD + 0.2 V) and rail-to-rail output swing (within 100 mV of rails at ±80 mA). This dual rail-to-rail capability allows full utilization of the supply voltage in single-supply 3.3-V or 5-V automotive systems, maximizing dynamic range for ADC interfacing and sensor signal conditioning tasks performed by the TLV2460QPWRQ1.
What is the shutdown behavior of TLV2460QPWRQ1?
When the SHDN pin (Pin 8) is pulled below 0.7 V, the TLV2460QPWRQ1 enters ultralow-power shutdown mode, reducing supply current to 0.3 μA per channel and placing the output in high-impedance state. Normal operation resumes within 7.6 μs after SHDN rises above 2 V. This behavior is fully characterized across –40°C to +125°C and is integral to power-gated architectures using the TLV2460QPWRQ1 in battery-supplied modules.
Can TLV2460QPWRQ1 drive capacitive loads?
Yes, the TLV2460QPWRQ1 is stable with capacitive loads up to 160 pF when driving a 10-kΩ load, maintaining ≥44° phase margin at unity gain. For larger loads, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended. This capability enables direct connection to ADC input capacitors and long PCB traces in automotive harnesses-common use cases for the TLV2460QPWRQ1 in distributed sensing nodes.
Is TLV2460QPWRQ1 pin-compatible with other devices in the TLV246x-Q1 family?
The TLV2460QPWRQ1 shares the same 8-pin TSSOP (PW) package and pinout with TLV2461QPWRQ1 and TLV2460AQPWRQ1, but differs from TLV2462QPWRQ1 (dual-channel) and TLV2463QPWRQ1 (quad-channel). Pin compatibility is limited to single-channel variants; SHDN functionality is present only on TLV2460QPWRQ1 and TLV2463QPWRQ1-so TLV2460QPWRQ1 cannot be substituted for TLV2461QPWRQ1 without circuit modification.
