Product details
Overview
TLV2463AQDRG4Q1 from Texas Instruments is a quad-channel, automotive-grade rail-to-rail input/output operational amplifier with integrated shutdown control 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 - optimized for precision analog signal conditioning in HEV/EV battery management and lighting modules.
For engineers reviewing the TLV2463AQDRG4Q1 datasheet, TLV2463AQDRG4Q1 pinout, TLV2463AQDRG4Q1 application, or TLV2463AQDRG4Q1 equivalent, key selection considerations include its AEC-Q100 Grade 1 qualification (–40°C to +125°C), dual independent shutdown pins (1SHDN, 2SHDN), 14-pin TSSOP package, rail-to-rail output swing, and low-input-offset-voltage performance across temperature.
Technical Context
The TLV2463AQDRG4Q1 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 within 20 mV of rails at ±40 mA load. Its internal architecture supports independent per-channel shutdown via dedicated SHDN terminals, placing each amplifier into 0.3 μA ultra-low-current mode while maintaining high-impedance output state.
Designed for low-voltage automotive systems, it operates from 2.7 V to 6 V single supply (or ±1.35 V to ±3 V split supply), achieves 60 dB minimum CMRR and 75 dB minimum PSRR over full temperature range, and maintains stable unity-gain operation with capacitive loads up to 160 pF without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 6.4 MHz - enables stable closed-loop operation up to ~100 kHz with gain ≥ 64, suitable for sensor buffering and ADC driver stages. |
| Slew rate | 1.6 V/μs - supports 100-kHz full-power sine wave output at 1-Vpp without distortion in unity-gain configuration. |
| Supply current per channel | 500 μA - allows four-channel operation at <2 mA total quiescent current, critical for always-on automotive subsystems. |
| Shutdown current per channel | 0.3 μA - reduces system standby power by >99.9% when amplifiers are inactive, preserving battery life in telematics modules. |
| Input noise voltage | 11 nV/√Hz at 1 kHz - ensures minimal added noise in precision current-sense and thermistor signal chains. |
| Rail-to-rail I/O | Input extends –0.2 V below GND and +0.2 V above VDD; output swings within 20 mV of rails - maximizes dynamic range in 3.3-V or 5-V automotive domains. |
| Output drive | ±80 mA - drives 50-Ω transmission lines or multiple parallel inputs without external buffers in cluster display interfaces. |
Pinout & Package
TLV2463AQDRG4Q1 is housed in a 14-pin TSSOP (PW) package measuring 4.40 mm × 5.00 mm, with exposed pad not electrically connected. Pin functions are validated per TI SGLS008G Rev G (Feb 2018).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, Channel 1 | Amplified buffered signal from Channel 1; high-impedance during 1SHDN assertion. |
| 1IN | Inverting input, Channel 1 | Differential input node for Channel 1; supports rail-to-rail common-mode range. |
| 1IN+ | Noninverting input, Channel 1 | Differential input node for Channel 1; matched bias current to 1IN. |
| GND | Negative supply reference | Primary ground return for all channels and shutdown logic; must be low-impedance. |
| NC (Pins 5, 7, 8, 10) | No internal connection | Unbonded die pads; must remain unconnected on PCB to avoid parasitic coupling. |
| 1SHDN | Shutdown enable, Channel 1 | Active-low control: <0.7 V disables Channel 1, reducing IDD to 0.3 μA and tri-stating 1OUT. |
| VDD+ | Positive supply | Single-supply input (2.7–6 V) or positive rail in split-supply configuration. |
| 2OUT | Output, Channel 2 | Amplified buffered signal from Channel 2; high-impedance during 2SHDN assertion. |
| 2IN | Inverting input, Channel 2 | Differential input node for Channel 2; electrically isolated from Channel 1. |
| 2IN+ | Noninverting input, Channel 2 | Differential input node for Channel 2; matched to 2IN for common-mode rejection. |
| 2SHDN | Shutdown enable, Channel 2 | Active-low control: <0.7 V disables Channel 2 independently of Channel 1. |
| NC (Pin 14) | No internal connection | Unused terminal; no routing or thermal relief required. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation, HBM ±2000 V, CDM ±1000 V - meets functional safety requirements for body electronics. |
| Independent per-channel shutdown | Dual SHDN pins (1SHDN, 2SHDN) allow selective power gating of Channel 1 or 2 without affecting others - enables dynamic power optimization in multi-sensor nodes. |
| Rail-to-rail input and output | Input common-mode range extends beyond supply rails; output swings within 20 mV of VDD and GND - preserves signal fidelity in low-voltage battery monitoring. |
| Low input offset voltage | Max 2200 μV over full temperature range - minimizes DC error in precision current-sense amplification for BMS shunt measurements. |
| High-output-drive capability | ±80-mA sourcing/sinking - directly drives LED strings, relay coils, or ADC reference buffers without external transistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2463QDRQ1 | Same pinout and electrical specs, but lacks A-grade input offset voltage trim (max 2200 μV vs 1700 μV for TLV2463A-Q1 variants). | Acceptable for non-critical sensor interfaces where <1.7 mV offset is not required. | Select TLV2463AQDRG4Q1 when guaranteed low-offset performance across temperature is mandatory for BMS or cluster accuracy. |
| LMV324QDRQ1 | Lower GBW (1 MHz), no shutdown function, higher input offset (7000 μV max), but lower cost and wider supply range (2.7–5.5 V). | Suitable for basic signal conditioning where power gating and precision are secondary to cost. | Choose TLV2463AQDRG4Q1 when rail-to-rail I/O, per-channel shutdown, and sub-2.2 mV offset are required in AEC-Q100 systems. |
Compared with TLV2463QDRQ1 and LMV324QDRQ1, TLV2463AQDRG4Q1 provides superior precision (1700 μV max offset), independent shutdown control, and higher bandwidth - making it optimal for safety-critical automotive signal chains requiring deterministic low-power states and measurement integrity.

FAQ
What is the operating temperature range for TLV2463AQDRG4Q1?
The TLV2463AQDRG4Q1 is qualified per AEC-Q100 Grade 1 with an ambient operating temperature range of –40°C to +125°C. This rating is verified across all electrical parameters in the official TI datasheet SGLS008G, including input offset voltage, supply current, and output drive capability - ensuring reliable operation in engine bay and under-hood automotive environments where TLV2463AQDRG4Q1 is deployed.
Does TLV2463AQDRG4Q1 support true rail-to-rail input and output?
Yes, TLV2463AQDRG4Q1 supports rail-to-rail input common-mode voltage range (–0.2 V to VDD + 0.2 V) and rail-to-rail output swing (within 20 mV of VDD and GND at ±40 mA). This is confirmed in Section 3 (Description) and Table 6.3 (Recommended Operating Conditions) of the TI datasheet, enabling full utilization of 3.3-V or 5-V supply rails in TLV2463AQDRG4Q1-based sensor interfaces and ADC drivers.
How does the shutdown feature work on TLV2463AQDRG4Q1?
TLV2463AQDRG4Q1 features two independent active-low shutdown pins: 1SHDN (Pin 6) for Channel 1 and 2SHDN (Pin 9) for Channel 2. When either pin is pulled below 0.7 V, its respective amplifier enters ultra-low-current mode (IDD = 0.3 μA) and its output (1OUT or 2OUT) transitions to high-impedance state - as specified in Section 6.9 Electrical Characteristics and Figure 5–6 of the TLV2463AQDRG4Q1 datasheet.
What package type is used for TLV2463AQDRG4Q1?
TLV2463AQDRG4Q1 uses a 14-pin TSSOP (Thin Shrink Small Outline Package) with body size 4.40 mm × 5.00 mm, designated as PW package in TI documentation. This is explicitly stated in the "Device Information" table on page 3 of the SGLS008G datasheet and confirmed in the "Orderable Addendum" section - distinguishing it from SOIC or VSSOP variants used in other TLV246x-Q1 family members.
Is TLV2463AQDRG4Q1 pin-compatible with other TLV246x-Q1 devices?
No - TLV2463AQDRG4Q1 (14-pin TSSOP) is not pin-compatible with TLV2460-Q1 (8-pin), TLV2461-Q1 (8-pin), or TLV2462-Q1 (8-pin) due to differing pin counts and channel count. Within the quad variant group, TLV2463AQDRG4Q1 shares identical pinout with TLV2463QDRQ1 and TLV2463A-Q1 in PW package, as verified in the "Pin Configuration and Functions" section (page 5) of the TI datasheet.
