Product details
Overview
TLV2463QDRG4Q1 from Texas Instruments is a quad-channel, automotive-grade rail-to-rail input/output operational amplifier with independent shutdown control per channel, 6.4 MHz gain-bandwidth product, 1.6 V/μs slew rate, ±80-mA output drive, and 500 μA/channel supply current - used in HEV/EV battery management and automotive lighting modules.
For engineers reviewing the TLV2463QDRG4Q1 datasheet, TLV2463QDRG4Q1 pinout, TLV2463QDRG4Q1 application, or TLV2463QDRG4Q1 equivalent, this page delivers verified electrical specs, TSSOP-14 package details, automotive AEC-Q100 Grade 1 qualification, shutdown timing behavior, and real-world use cases in powertrain signal conditioning and ADC buffering.
Technical Context
The TLV2463QDRG4Q1 implements a CMOS input stage enabling rail-to-rail common-mode input range (–0.2 V to VDD + 0.2 V) and rail-to-rail output swing, supporting low-voltage operation down to 2.7 V single-supply. Its 6.4-MHz unity-gain bandwidth and 1.6-V/μs slew rate are maintained at 500-μA/channel quiescent current.
Each of the four amplifiers features an independent active-low SHDN pin (pins 6 and 9 for channels 1 and 2; pins 10 and 13 for channels 3 and 4 per functional diagram), placing the corresponding output in high-impedance state and reducing supply current to 0.3 μA/channel during shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable unity-gain buffer configurations up to ~6 MHz with minimal phase margin degradation. |
| Slew Rate | 1.6 V/μs - supports clean 10-kHz, 2-VPP sine wave output into 10-kΩ load without distortion. |
| Output Drive | ±80 mA - drives heavy capacitive loads (e.g., 160 pF) while maintaining settling time < 3.4 μs (0.01%). |
| Supply Current (per channel) | 500 μA - enables ultra-low-power operation in always-on vehicle subsystems like battery monitoring. |
| Shutdown Current (per channel) | 0.3 μA - reduces total system standby power by >99.9% when unused channels are disabled. |
| Input Offset Voltage | 150–2000 μV (max over temp) - ensures <1 mV error in 12-bit ADC front-end applications at 3.3 V full-scale. |
| Common-Mode Input Range | –0.2 V to VDD + 0.2 V - accepts signals beyond rails, critical for direct sensing of shunt voltages near ground or supply. |
Pinout & Package
TLV2463QDRG4Q1 is housed in a 14-pin TSSOP (PW) package measuring 4.40 mm × 5.00 mm, optimized for automotive PCB space constraints and thermal performance (RθJA = 185.7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, Channel 1 | Amplified buffered signal; high-impedance during SHDN assertion. |
| 1IN– | Inverting Input, Channel 1 | Differential node for inverting configurations; rail-to-rail common-mode range. |

| GND | Negative Supply | System ground reference; shared return path for all four channels. |
| NC (Pins 5, 7, 8, 10) | No Internal Connection | Unbonded die pads; must remain unconnected on PCB to avoid parasitic coupling. |
| 1SHDN | Shutdown Control, Channel 1 | Active-low logic input; pulls channel 1 output to Hi-Z and cuts IDD to 0.3 μA. |
| VDD+ | Positive Supply | Single 2.7–6 V or split ±1.35–±3 V rail; decoupling capacitor required at pin. |
| 2OUT | Output, Channel 2 | Independent output; electrically isolated from other channels during shutdown. |
| 2IN– | Inverting Input, Channel 2 | Configurable for differential sensing or active filtering in telematics analog front-ends. |
| 2IN+ | Noninverting Input, Channel 2 | Accepts bias-stable inputs from temperature sensors or potentiometers. |
| 2SHDN | Shutdown Control, Channel 2 | Independent enable/disable for channel 2; no cross-talk with other SHDN pins. |
| 3IN– / 3IN+ / 3OUT | Inverting/Noninverting Input & Output, Channel 3 | Full functional replication of channel 1; pin 11 = 3IN+, pin 12 = 3IN–, pin 8 = 3OUT. |
| 4IN– / 4IN+ / 4OUT | Inverting/Noninverting Input & Output, Channel 4 | Full functional replication of channel 2; pin 12 = 4IN–, pin 13 = 4OUT, pin 14 = VDD+. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2463AQDRQ1 | Lower input offset voltage (150 μV typ vs. 200 μV typ); same pinout, package, and shutdown architecture. | Better suited for precision current sensing where offset drift impacts calibration accuracy over temperature. | Select TLV2463AQDRQ1 when <150-μV max VIO is required across –40°C to +125°C; otherwise TLV2463QDRG4Q1 offers cost-optimized performance. |
| LMV324QDRQ1 | Higher supply current (120 μA/channel), no shutdown function, lower GBW (1 MHz), but wider supply range (2.7–5.5 V). | Limited to non-critical signal paths where power gating is unnecessary and bandwidth <1 MHz suffices. | Choose LMV324QDRQ1 only for legacy designs requiring drop-in replacement without layout change - not for new designs needing shutdown or >1-MHz bandwidth. |
Compared with TLV2463AQDRQ1, TLV2463QDRG4Q1 trades 50-μV higher typical offset for broader availability and lower unit cost; compared with LMV324QDRQ1, it adds per-channel shutdown and 6.4× higher bandwidth at just 4× higher quiescent current - making it optimal for modern automotive signal chains demanding both precision and configurability.

FAQ
What is the operating temperature range for TLV2463QDRG4Q1?
The TLV2463QDRG4Q1 is qualified per AEC-Q100 Grade 1, with guaranteed operation from –40°C to +125°C ambient temperature. This range covers under-hood environments in HEV/EV applications and interior modules exposed to solar loading. All electrical specifications in the datasheet are validated across this full range, including input offset voltage drift and shutdown current stability.
Does TLV2463QDRG4Q1 support single-supply operation?
Yes, TLV2463QDRG4Q1 supports true single-supply operation from 2.7 V to 6 V. Its rail-to-rail input stage accepts common-mode voltages from –0.2 V to VDD + 0.2 V, and its rail-to-rail output swings within 100 mV of each rail under 2.5-mA load - enabling direct interfacing with 3.3-V microcontrollers and ADCs without level-shifting circuitry.
How does the shutdown feature work on TLV2463QDRG4Q1?
TLV2463QDRG4Q1 provides four independent active-low shutdown pins: 1SHDN (pin 6), 2SHDN (pin 9), 3SHDN (pin 10), and 4SHDN (pin 13). When pulled below 0.7 V, each pin disables its respective amplifier, forcing the output into high-impedance state and reducing that channel's supply current to 0.3 μA. All four channels can be controlled separately for granular power management.
What package type is used for TLV2463QDRG4Q1?
TLV2463QDRG4Q1 is supplied in a 14-pin TSSOP (PW) package with nominal dimensions of 4.40 mm × 5.00 mm. This surface-mount package features gull-wing leads, is RoHS-compliant, and is optimized for automated assembly and thermal dissipation in automotive PCBs - with a junction-to-ambient thermal resistance (RθJA) of 185.7°C/W.
Is TLV2463QDRG4Q1 pin-compatible with other TLV246x-Q1 variants?
TLV2463QDRG4Q1 shares the same 14-pin TSSOP (PW) footprint and pinout with TLV2463AQDRQ1 and TLV2464AQDRQ1, but is not pin-compatible with dual (TLV2462-Q1) or single (TLV2461-Q1) variants due to differing channel count and pin assignments. Always verify pin functions using the official TI datasheet schematic for TLV2463QDRG4Q1 before board reuse.
