Product details
Overview
TLV2460AQPWRG4Q1 from Texas Instruments is a single-channel, automotive-grade rail-to-rail input/output operational amplifier with shutdown functionality, designed for battery management and lighting modules in HEV/EV powertrains. It delivers 6.4 MHz gain bandwidth, 1.6 V/μs slew rate, ±80-mA output drive, 500 μA/channel supply current, and operates from 2.7 V to 6 V across –40°C to +125°C.
For engineers reviewing the TLV2460AQPWRG4Q1 datasheet, TLV2460AQPWRG4Q1 pinout, TLV2460AQPWRG4Q1 application, or TLV2460AQPWRG4Q1 equivalent, key selection criteria include rail-to-rail dynamic range at low supply voltage, ultra-low shutdown current (0.3 μA/channel), AEC-Q100 Grade 1 qualification, and verified performance in DC-DC inverter feedback loops and analog sensor buffering.
Technical Context
The TLV2460AQPWRG4Q1 implements a CMOS input stage enabling rail-to-rail input common-mode range (–0.2 V to VDD + 0.2 V) and rail-to-rail output swing with high-current capability. Its internal architecture supports stable unity-gain operation with 45° phase margin into 160 pF capacitive loads.
Shutdown control is active-low (SHDN < 0.7 V), placing the amplifier in ultra-low IDD mode while forcing output to high-impedance state-critical for power sequencing in automotive body electronics. Input offset voltage is specified at 150 μV (typ) / 1700 μV (max) over full temperature range.
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 |
| Slew Rate | 1.6 V/μs - supports fast transient response in motor control feedback and sensor signal conditioning |
| Supply Current (per channel) | 0.55 mA (typ) at 5 V - enables multi-channel systems with constrained power budgets |
| Shutdown Current | 0.3 μA (typ) - reduces system standby power in telematics and cluster modules |
| Rail-to-Rail I/O | Input range: –0.2 V to VDD + 0.2 V; Output swing: within 100 mV of rails - maximizes dynamic range in 3.3 V or 5 V systems |
| Output Drive | ±80 mA - drives low-impedance loads such as LED drivers or ADC reference buffers directly |
| Input Noise Voltage | 11 nV/√Hz at 1 kHz - suitable for precision signal amplification in battery voltage monitoring |
Pinout & Package
TSSOP-8 (PW) package, 4.40 mm × 3.00 mm body size, 0.65 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left floating or grounded per layout guidelines |
| 2 | IN− | Inverting input - accepts differential or single-ended signals with rail-to-rail common-mode range |
| 3 | IN+ | Noninverting input - high-impedance CMOS node; sensitive to PCB leakage and ESD |
| 4 | GND | Negative supply reference - requires low-inductance connection to system ground plane |
| 5 | NC | No internal connection - must be left floating or grounded per layout guidelines |
| 6 | OUT | Amplifier output - capable of sourcing/sinking ±80 mA; requires local 100 nF bypass capacitor |
| 7 | VDD+ | Positive supply - accepts 2.7 V to 6 V; decoupling mandatory for stability |
| 8 | SHDN | Active-low shutdown control - logic-low (<0.7 V) disables amplifier and reduces IDD to 0.3 μA |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation in automotive powertrain and body control units |

| Ultra-low shutdown current (0.3 μA) | Enables always-on subsystems (e.g., intrusion detection) to maintain microamp-level quiescent power |
| 11 nV/√Hz input noise density | Supports accurate measurement of small-signal battery cell voltages without added amplification stages |
| 6.4-MHz GBW at 0.55 mA | Provides bandwidth headroom for closed-loop stability in DC-DC converter error amplifiers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2460QPWRQ1 | Standard version (non-A grade); higher max input offset voltage (2000 μV vs. 1700 μV) | Less suited for precision battery cell monitoring where offset drift impacts SoC accuracy | Select TLV2460AQPWRG4Q1 when guaranteed low-offset performance across temperature is required |
| LM7321QDRQ1 | Higher supply current (1.3 mA vs. 0.55 mA), no shutdown pin, wider supply range (2.7–36 V) | Better for high-voltage analog front-ends but incompatible with ultra-low-power shutdown sequencing | Choose LM7321QDRQ1 only if rail-to-rail output and wide supply are prioritized over micropower shutdown |
Compared with TLV2460QPWRQ1 and LM7321QDRQ1, TLV2460AQPWRG4Q1 uniquely combines A-grade precision (150 μV typ offset), integrated shutdown, and automotive qualification in a TSSOP-8 footprint-making it optimal for space-constrained, low-power, safety-critical signal conditioning.

FAQ
What is the operating temperature range of the TLV2460AQPWRG4Q1?
The TLV2460AQPWRG4Q1 is qualified for automotive Grade 1 operation, supporting continuous operation from –40°C to +125°C ambient temperature. This rating is validated per AEC-Q100 standards and applies across all electrical specifications in the datasheet, including input offset voltage, supply current, and gain bandwidth.
Does TLV2460AQPWRG4Q1 support true rail-to-rail input and output?
Yes, TLV2460AQPWRG4Q1 supports rail-to-rail input with common-mode range extended to –0.2 V below GND and 0.2 V above VDD, and rail-to-rail output swing within 100 mV of both supply rails under 10-mA load. This enables full utilization of ADC input ranges in 3.3-V and 5-V automotive systems.
How does the shutdown function work on TLV2460AQPWRG4Q1?
The SHDN pin (Pin 8) is active-low: pulling it below 0.7 V places TLV2460AQPWRG4Q1 into ultra-low-power shutdown mode (IDD = 0.3 μA typical), while the output enters high-impedance state. Releasing SHDN to >2 V restores normal operation with 7.6-μs turn-on time-critical for power-gating in modular ECUs.
What is the maximum capacitive load TLV2460AQPWRG4Q1 can drive stably?
TLV2460AQPWRG4Q1 maintains 45° phase margin and stable unity-gain operation with up to 160 pF capacitive load, as confirmed in the datasheet's Typical Characteristics (Figure 36). For loads exceeding 100 pF, TI recommends adding a 10-Ω series resistor between OUT and the capacitor to preserve stability.
Is TLV2460AQPWRG4Q1 pin-compatible with other devices in the TLV246x-Q1 family?
TLV2460AQPWRG4Q1 shares the same TSSOP-8 (PW) pinout as TLV2460QPWRQ1 and TLV2461AQPWRG4Q1 (single/dual variants), but is not pin-compatible with dual or quad versions like TLV2462A-Q1 (SOIC-8/VSSOP-8) or TLV2463A-Q1 (TSSOP-14). Always verify pin functions using the official TI datasheet for each variant.
