Product details
Overview
TLV2460AQDRG4Q1 from Texas Instruments is a single-channel, automotive-grade rail-to-rail input/output operational amplifier with shutdown functionality. It delivers 6.4 MHz gain bandwidth, 1.6 V/μs slew rate, ±80-mA output drive, and 500 μA/channel supply current at 5 V, operating across –40°C to +125°C for battery management and lighting modules in HEV/EV powertrain systems.
For engineers reviewing the TLV2460AQDRG4Q1 datasheet, TLV2460AQDRG4Q1 pinout, TLV2460AQDRG4Q1 application, or TLV2460AQDRG4Q1 equivalent, key selection criteria include rail-to-rail I/O swing, ultra-low shutdown current (0.3 μA/channel), AEC-Q100 Grade 1 qualification, input offset voltage ≤150 μV (typ), and TSSOP-8 package compatibility with space-constrained automotive PCB layouts.
Technical Context
The TLV2460AQDRG4Q1 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 10 mV of rails at ±10 mA load. Its internal architecture supports stable unity-gain operation with 45° phase margin into 160 pF capacitive loads while maintaining 6.4 MHz GBW.
Shutdown control is active-low (SHDN < 0.7 V), placing the amplifier in high-impedance output state and reducing supply current to 0.3 μA/channel. The device meets AEC-Q100 Grade 1 requirements, including HBM ESD ≥2000 V and CDM ESD ≥1000 V, ensuring robustness in automotive environments.
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 (e.g., AV = 6) in sensor signal conditioning. |
| Slew Rate | 1.6 V/μs - Supports clean amplification of 100-kHz sine waves at 1-Vpp without distortion in ADC driver applications. |
| Output Drive | ±80 mA - Drives low-impedance loads (e.g., 50-Ω transmission lines or LED bias networks) without external buffers. |
| Supply Current | 0.55 mA/channel (typ @ 5 V) - Enables multi-channel analog front-ends in battery-powered ECUs with sub-2-mA total quiescent budget. |
| Input Offset Voltage | 150 μV (max @ 25°C, TLV2460A-Q1 variant) - Ensures ≤0.3% error in 0.05-V full-scale current-sense amplification. |
| Shutdown Current | 0.3 μA/channel - Reduces system standby power by >99.9% vs active mode, critical for always-on vehicle subsystems. |
| Common-Mode Range | –0.2 V to VDD + 0.2 V - Interfaces directly with 0–3.3 V or 0–5 V microcontroller ADC references without level-shifting. |
Pinout & Package
TLV2460AQDRG4Q1 is housed in an 8-pin TSSOP (PW) package measuring 4.40 mm × 3.00 mm, optimized for automated SMT assembly and thermal performance (RθJA = 185.7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused pad; must be left floating or grounded per layout guidelines to avoid parasitic coupling. |
| 2 (IN–) | Inverting input | Accepts feedback or inverted signal path; high-impedance CMOS input (IIB ≤14 nA) minimizes resistor noise contribution. |
| 3 (IN+) | Noninverting input | High-impedance node for reference or sensor input; supports rail-to-rail common-mode range down to –0.2 V. |
| 4 (GND) | Negative supply | Primary return path for all channels; requires low-inductance connection to system ground plane. |
| 5 (NC) | No internal connection | Unused pad; no electrical function; may be used as thermal pad anchor if soldered to copper pour. |
| 6 (OUT) | Amplifier output | Rail-to-rail capable output driving ±80 mA; enters high-Z state during shutdown (SHDN low). |
| 7 (VDD+) | Positive supply | Operates from 2.7 V to 6 V single supply; decoupling capacitor (≥100 nF) required within 2 mm. |
| 8 (SHDN) | Active-low shutdown | Pulls to GND to disable amplifier; logic-high (>2 V) enables normal operation; compatible with 3.3-V or 5-V GPIO. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2460QDRQ1 | Standard grade (non-A) with higher max input offset voltage (2000 μV vs 1500 μV) and wider tempco (2 μV/°C same). | Less suitable for precision current sensing where sub-1-mV offset is required over temperature. | Select TLV2460AQDRG4Q1 when 150-μV max offset at 25°C and tighter production spread are mandatory. |
| LMV931QDBVRQ1 | Single-channel, rail-to-rail I/O op-amp with lower GBW (1.5 MHz), higher supply current (120 μA), and no shutdown pin. | Lacks shutdown capability and bandwidth needed for fast-settling BMS or telematics filtering. | Choose TLV2460AQDRG4Q1 when system-level power gating and >5-MHz signal fidelity are design requirements. |
Compared with TLV2460QDRQ1 and LMV931QDBVRQ1, TLV2460AQDRG4Q1 uniquely combines AEC-Q100 Grade 1 qualification, 0.3-μA shutdown, 6.4-MHz GBW, and 150-μV max input offset-making it optimal for precision, power-aware automotive signal chains where both accuracy and energy efficiency are constrained.

FAQ
What is the maximum operating temperature range for TLV2460AQDRG4Q1?
The TLV2460AQDRG4Q1 is qualified per AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. This rating applies to the full device-including input stage, output stage, and shutdown circuitry-and is validated across production lots, making TLV2460AQDRG4Q1 suitable for under-hood and powertrain applications where thermal stress is severe.
Does TLV2460AQDRG4Q1 support true rail-to-rail input and output operation?
Yes, TLV2460AQDRG4Q1 supports 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 VDD and GND at ±10 mA). This capability is specified across the full –40°C to +125°C temperature range and enables direct interfacing with 3.3-V or 5-V microcontroller ADCs without external level-shifting components in TLV2460AQDRG4Q1-based designs.
What is the typical supply current of TLV2460AQDRG4Q1 at 5 V operation?
The typical supply current of TLV2460AQDRG4Q1 is 0.55 mA per channel at VDD = 5 V and TA = 25°C, with a maximum of 1 mA across the full temperature range. In shutdown mode (SHDN < 0.7 V), supply current drops to 0.3 μA per channel-reducing power consumption by >99.9%-a key feature leveraged in TLV2460AQDRG4Q1 implementations for intermittent-sensing automotive subsystems.
Is TLV2460AQDRG4Q1 pin-compatible with other devices in the TLV246x-Q1 family?
TLV2460AQDRG4Q1 uses the standard 8-pin TSSOP (PW) footprint shared with TLV2460QDRQ1 and TLV2461A-Q1 variants, but pin functions differ across configurations. Specifically, TLV2460AQDRG4Q1 has dedicated SHDN on Pin 8 and NC on Pins 1 and 5, whereas dual-channel TLV2462-Q1 variants repurpose those pins for second-channel I/O. Therefore, TLV2460AQDRG4Q1 is not drop-in compatible with dual or quad versions-PCB layout must match the single-channel, shutdown-enabled pinout of TLV2460AQDRG4Q1.
What packaging and ordering information applies to TLV2460AQDRG4Q1?
TLV2460AQDRG4Q1 is supplied in tape-and-reel format (2500 units per reel) in an 8-pin TSSOP (PW) package with dimensions 4.40 mm × 3.00 mm. The "G4Q1" suffix denotes automotive qualification (Q1), green (Pb-free) finish, and TI's standard quality grade. It is orderable through authorized distributors and Aetrix Electronics with full traceability to TI's manufacturing lot records.
