Product details
Overview
TLV2463AQPWRG4Q1 from Texas Instruments is a quad-channel, automotive-grade rail-to-rail input/output operational amplifier with shutdown functionality, designed for HEV/EV powertrain and battery management systems. It delivers 6.4 MHz gain bandwidth, 1.6 V/μs slew rate, ±80-mA output drive, 500 μA/channel supply current, and 11 nV/√Hz input noise voltage.
For engineers reviewing the TLV2463AQPWRG4Q1 datasheet, TLV2463AQPWRG4Q1 pinout, TLV2463AQPWRG4Q1 application, or TLV2463AQPWRG4Q1 equivalent, key selection considerations include its AEC-Q100 Grade 1 qualification (–40°C to +125°C), dual independent shutdown pins (1SHDN, 2SHDN), TSSOP-14 package, and rail-to-rail output swing into heavy loads - critical for ADC buffering and precision sensor signal conditioning in safety-critical automotive subsystems.
Technical Context
The TLV2463AQPWRG4Q1 integrates four independent op-amp channels in a single 14-pin TSSOP package, each featuring rail-to-rail input common-mode range extending beyond supply rails (–0.2 V to VDD + 0.2 V) and rail-to-rail output swing. Its architecture supports low-voltage operation from 2.7 V to 6 V single supply or ±1.35 V to ±3 V split supply.
Each channel includes dedicated shutdown control (1SHDN on Pin 6, 2SHDN on Pin 9), enabling ultra-low quiescent current (0.3 μA/channel) while placing the output in high-impedance state. The device maintains 6.4-MHz unity-gain bandwidth and 45° phase margin at 10-kΩ load with 160-pF capacitive load, ensuring stable operation in feedback configurations typical of active filtering and transducer interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop operation up to ~100 kHz with moderate gain, suitable for anti-aliasing and sensor signal conditioning. |
| Slew Rate | 1.6 V/μs - supports 100-kHz full-power bandwidth for 1-Vpp signals, sufficient for fast transient response in motor control feedback paths. |
| Output Drive | ±80 mA - drives low-impedance loads (e.g., 37.5 Ω at 3 V) without external buffers, reducing BOM count in lighting module drivers. |
| Supply Current | 500 μA/channel - enables always-on monitoring circuits in battery management systems with minimal standby power impact. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - preserves SNR in precision current-sense amplification for cell voltage monitoring in EV battery packs. |
| Shutdown Current | 0.3 μA/channel - allows selective channel disablement during sleep modes while maintaining system-level power budget compliance. |
| Common-Mode Range | –0.2 V to VDD + 0.2 V - accommodates ground-referenced sensors and rail-sensing topologies in 12-V automotive systems. |
Pinout & Package
The TLV2463AQPWRG4Q1 is housed in a 14-pin TSSOP (PW) package measuring 4.40 mm × 5.00 mm, optimized for automated assembly and thermal performance in dense automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN, 2IN, 3IN, 4IN | Inverting input (Ch1–Ch4) | Accepts differential or inverting configuration signals; supports rail-to-rail common-mode range for direct connection to shunt resistors or thermistors. |
| 1IN+, 2IN+, 3IN+, 4IN+ | Noninverting input (Ch1–Ch4) | Enables high-impedance sensing of reference voltages, potentiometer wipers, or Hall-effect sensor outputs without loading. |
| 1OUT, 2OUT, 3OUT, 4OUT | Output (Ch1–Ch4) | Rail-to-rail swing delivers full dynamic range to downstream ADCs or comparators; ±80-mA drive supports direct LED or relay coil driving. |
| 1SHDN, 2SHDN | Shutdown control (Ch1 & Ch2) | Active-low logic inputs (VIH = 2 V, VIL = 0.7 V) enable per-channel power gating - critical for functional safety partitioning in ASIL-B systems. |
| GND | Negative supply | Single-point grounding required for noise-sensitive analog sections; ties to chassis or battery negative in automotive modules. |
| VDD+ | Positive supply | Accepts 2.7–6 V single supply; decoupling with 100-nF ceramic capacitor near Pin 14 essential for EMI immunity in noisy vehicle environments. |
| NC (Pins 5, 7, 8, 10) | No internal connection | Must remain unconnected; no routing or thermal vias permitted to avoid parasitic coupling or mechanical stress on die attach. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2463QPWRQ1 | Standard version without 'A' grade; higher max input offset voltage (2000 μV vs. 1500 μV) and wider tempco (2.5 μV/°C vs. 2 μV/°C). | Less suitable for high-accuracy BMS voltage monitoring but acceptable for non-critical lighting or HVAC signal paths. | Select TLV2463QPWRQ1 only when cost sensitivity outweighs precision requirements and full Grade 1 validation is not mandated. |
| LMV324QDRQ1 | Lower GBW (1 MHz), no shutdown function, higher input bias current (100 nA vs. 14 nA), and no AEC-Q100 Grade 1 certification. | Limited to cabin infotainment or comfort systems where ASIL compliance is not required. | Use LMV324QDRQ1 only in non-safety-critical subsystems with relaxed AC performance and no channel-level power gating needs. |
Compared with TLV2463QPWRQ1 and LMV324QDRQ1, the TLV2463AQPWRG4Q1 provides superior precision (150 μV offset), guaranteed shutdown functionality, and full AEC-Q100 Grade 1 qualification - making it the only option qualified for ASIL-B–capable battery monitoring and powertrain control loops.

FAQ
What is the operating temperature range for the TLV2463AQPWRG4Q1?
The TLV2463AQPWRG4Q1 is qualified per AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. This range is validated for under-hood and powertrain applications, with thermal metrics including RθJA = 185.7°C/W (TSSOP-14) confirming safe junction temperatures under typical automotive power dissipation conditions.
Does the TLV2463AQPWRG4Q1 support rail-to-rail input and output?
Yes, the TLV2463AQPWRG4Q1 supports rail-to-rail input common-mode voltage range (–0.2 V to VDD + 0.2 V) and rail-to-rail output swing. This allows full utilization of supply voltage headroom in 3.3-V or 5-V automotive systems, eliminating the need for external level-shifting circuitry when interfacing with microcontrollers or ADCs.
How many channels does the TLV2463AQPWRG4Q1 have, and what shutdown capability does it offer?
The TLV2463AQPWRG4Q1 integrates four independent operational amplifier channels in a single 14-pin TSSOP package. It features two dedicated shutdown pins - 1SHDN (Pin 6) for Channel 1 and 2SHDN (Pin 9) for Channel 2 - enabling per-channel power gating while Channels 3 and 4 remain active, supporting functional safety partitioning.
What is the typical supply current per channel for the TLV2463AQPWRG4Q1?
The TLV2463AQPWRG4Q1 draws 500 μA per channel under normal operation (VDD = 3 V or 5 V, TA = 25°C). In shutdown mode (SHDN < 0.7 V), supply current drops to 0.3 μA per enabled channel, making it suitable for always-on monitoring circuits in battery management systems where ultra-low standby power is mandatory.
Is the TLV2463AQPWRG4Q1 pin-compatible with other devices in the TLV246x-Q1 family?
The TLV2463AQPWRG4Q1 uses a 14-pin TSSOP (PW) package and shares identical pinout with TLV2463QPWRQ1 and TLV2463AQPWRQ1. However, it is not pin-compatible with dual-channel (TLV2462x-Q1) or single-channel (TLV2461x-Q1) variants due to differing pin counts and functions - always verify package and pin mapping before board reuse.
