Product details
Overview
TLV2464AQPWRG4Q1 from Texas Instruments is a quad-channel, automotive-grade rail-to-rail input/output operational amplifier with shutdown capability per channel. 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 - enabling high-fidelity signal conditioning in battery management and lighting control systems.
For engineers reviewing the TLV2464AQPWRG4Q1 datasheet, TLV2464AQPWRG4Q1 pinout, TLV2464AQPWRG4Q1 application, or TLV2464AQPWRG4Q1 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification (–40°C to +125°C), rail-to-rail output swing with high-current drive, micropower shutdown mode (0.3 μA/channel), and TSSOP-14 package compatibility for space-constrained automotive PCB layouts.
Technical Context
The TLV2464AQPWRG4Q1 implements a CMOS-input, rail-to-rail output architecture optimized for low-voltage operation (2.7 V to 6 V) in automotive subsystems. Its input common-mode range extends 0.2 V beyond both rails, supporting full dynamic range in single-supply configurations typical of HEV/EV battery monitors and lighting modules.
Each of its four independent amplifiers features dedicated shutdown control (pins 1SHDN and 2SHDN), placing the output in high-impedance state while drawing only 0.3 μA per channel. The device maintains stable unity-gain operation with capacitive loads up to 160 pF and achieves 45° phase margin at 5 V supply, ensuring robust closed-loop performance without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 6.4 MHz - enables stable AC-coupled filtering and sensor signal amplification up to ~1 MHz with gain ≥6 |
| Slew rate | 1.6 V/μs - supports 10-kHz full-scale sine wave output at 10-Vpp without distortion |
| Output drive | ±80 mA - drives 37.5-Ω loads directly, eliminating need for external buffer stages in LED driver feedback paths |
| Supply current | 500 μA/channel - allows continuous operation in always-on vehicle modules with <2 mA total quiescent draw |
| Input noise voltage | 11 nV/√Hz - preserves SNR in precision current-sense amplification for battery cell monitoring |
| Shutdown current | 0.3 μA/channel - reduces system standby power by >99% versus active mode, critical for ignition-off BMS sleep states |
| Common-mode range | –0.2 V to VDD + 0.2 V - accepts ground-referenced inputs and rail-swing outputs in 3.3-V or 5-V automotive domains |
Pinout & Package
The TLV2464AQPWRG4Q1 is housed in a 14-pin TSSOP package (4.40 mm × 5.00 mm body size) with exposed pad for thermal enhancement. Pin 1 is marked by a dot or beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT, 2OUT, 3OUT, 4OUT | Amplifier output | Push-pull rail-to-rail outputs capable of sourcing/sinking ±80 mA; high-Z during shutdown |
| 1IN, 2IN, 3IN, 4IN | Inverting input | CMOS input with 14-nA max bias current at 25°C; supports high-impedance feedback networks |
| 1IN+, 2IN+, 3IN+, 4IN+ | Noninverting input | Matched to inverting inputs; enables precision differential sensing and reference buffering |
| 1SHDN, 2SHDN | Channel shutdown control | Active-low logic inputs; <0.7 V enables shutdown (0.3 μA), >2 V enables operation (500 μA) |
| GND | Negative supply | Primary return path for all channels and shutdown logic; requires low-impedance connection to system ground plane |
| VDD+ | Positive supply | Single-supply input (2.7–6 V); powers all four op-amps and internal bias circuitry |
| NC (pins 5, 7, 8, 10) | No internal connection | Unbonded pins; must remain unconnected and unstubbed to avoid parasitic coupling |
Key Features
| Feature | Design Value |

| Rail-to-rail input and output | Enables full utilization of 3.3-V or 5-V supply rails in single-ended sensor interfaces and DAC output buffers |
| Per-channel shutdown | Independent enable/disable of each amplifier reduces system-level power without reconfiguring signal routing |
| High-output-drive capability | Eliminates need for discrete output transistors in LED current regulation and motor position feedback circuits |
| Low input offset voltage | 150 μV max (TLV2464A-Q1 variant) ensures <0.005% gain error in 12-bit precision current sensing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464QPWRQ1 | Standard grade (non-A) version with 2000-μV max input offset vs. 1500-μV for TLV2464AQPWRG4Q1; identical pinout, package, and electrical specs otherwise | Acceptable for non-precision functions like general-purpose buffering where offset drift <2 mV is tolerable | Select TLV2464QPWRQ1 only when cost sensitivity outweighs need for tighter offset spec in BMS or lighting calibration paths |
| LMV324QDRQ1 | Lower bandwidth (1 MHz), lower output drive (40 mA), no per-channel shutdown; SOIC-14 package only | Suitable for basic sensor interfacing but not for high-speed or high-current applications like inverter control or LED drivers | Choose LMV324QDRQ1 only for legacy designs requiring drop-in replacement without layout change, accepting reduced performance margins |
Compared with TLV2464QPWRQ1 and LMV324QDRQ1, the TLV2464AQPWRG4Q1 provides superior precision (lower VIO), higher output current, and granular power control via dual shutdown pins - making it the optimal choice for next-generation automotive subsystems demanding accuracy, efficiency, and functional safety compliance.

FAQ
What is the operating temperature range for TLV2464AQPWRG4Q1?
The TLV2464AQPWRG4Q1 is qualified per AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. This rating covers junction temperatures up to 150°C and is validated across the full supply range (2.7 V to 6 V), making TLV2464AQPWRG4Q1 suitable for under-hood and battery-pack environments in electric vehicles.
Does TLV2464AQPWRG4Q1 support rail-to-rail input and output simultaneously?
Yes, TLV2464AQPWRG4Q1 supports true rail-to-rail input common-mode range (–0.2 V to VDD + 0.2 V) and rail-to-rail output swing (within 10 mV of each rail at ±10 mA). This allows TLV2464AQPWRG4Q1 to operate with full dynamic range in single-supply 3.3-V or 5-V systems, such as those used in automotive sensor signal chains and LED driver feedback loops.
How does the shutdown feature work on TLV2464AQPWRG4Q1?
TLV2464AQPWRG4Q1 provides two independent shutdown pins: 1SHDN (pin 6) controls channels 1 and 2, and 2SHDN (pin 9) controls channels 3 and 4. Driving either pin below 0.7 V places its associated channels into ultra-low-power shutdown (0.3 μA/channel), with outputs entering high-impedance state. TLV2464AQPWRG4Q1 remains fully functional with one pair active while the other is shut down, enabling dynamic power optimization.
What is the maximum capacitive load TLV2464AQPWRG4Q1 can drive stably?
TLV2464AQPWRG4Q1 maintains stability with capacitive loads up to 160 pF when configured as a unity-gain follower, as verified in the datasheet's Typical Characteristics section (Figure 36, Phase margin vs load capacitance). For loads exceeding 160 pF, external series resistance (≥10 Ω) at the output is recommended to preserve phase margin above 45° and prevent peaking or oscillation in TLV2464AQPWRG4Q1-based circuits.
Is TLV2464AQPWRG4Q1 pin-compatible with other devices in the TLV246x-Q1 family?
TLV2464AQPWRG4Q1 uses the 14-pin TSSOP (PW) package and shares identical pinout with TLV2463A-Q1 variants in the same package. However, it is not pin-compatible with dual (TLV2462-Q1) or single (TLV2461-Q1) versions due to differing channel count and pin assignments. Always verify pin functions using the "Pin Functions" table in the TLV2464AQPWRG4Q1 datasheet before board reuse.
