Product details
Overview
TLV2462AQDRQ1 from Texas Instruments is a dual-channel, automotive-grade rail-to-rail input/output operational amplifier with shutdown capability, 6.4-MHz gain bandwidth, 1.6-V/μs slew rate, ±80-mA output drive, and 500-μA/channel supply current - used in HEV/EV battery management and powertrain signal conditioning.
For engineers reviewing the TLV2462AQDRQ1 datasheet, TLV2462AQDRQ1 pinout, TLV2462AQDRQ1 application, or TLV2462AQDRQ1 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification (–40°C to +125°C), rail-to-rail output swing, low input offset voltage (150 μV typ), shutdown current (1 μA max), and SOIC-8 package compatibility for space-constrained automotive modules.
Technical Context
The TLV2462AQDRQ1 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 ±40-mA load. Its 6.4-MHz unity-gain bandwidth and 1.6-V/μs slew rate support stable closed-loop operation up to 10 kHz with 0.01% settling in ≤1.83 μs (CL = 56 pF, AV = –1).
It features independent channel shutdown control (SHDN pin), delivering ultra-low 1-μA max shutdown current per channel while placing outputs in high-impedance state. Input noise voltage is 11 nV/√Hz at 1 kHz, and CMRR reaches 85 dB (typ) over 0–5 V common-mode range at 5 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable unity-gain buffer or gain-of-10 amplification up to ~640 kHz without phase margin degradation. |
| Slew Rate | 1.6 V/μs - enables full-scale 2-VPP output step response in <1.83 μs with 0.01% accuracy under 56-pF capacitive load. |
| Output Drive | ±80 mA - drives 10-kΩ loads to rail with <100-mV headroom and sustains 10-mA sourcing/sinking at rail compliance. |
| Supply Current | 0.55–0.65 mA/channel - enables dual op-amp operation from 3–5 V supplies with sub-1.3-mA total quiescent draw. |
| Input Offset Voltage | 150 μV (typ) - ensures ≤0.03% gain error in 12-bit precision sensor front-ends at room temperature. |
| Shutdown Current | 1 μA max per channel - reduces system standby power by >99.8% versus active mode, critical for always-on vehicle modules. |
| Common-Mode Range | –0.2 V to VDD + 0.2 V - accepts inputs beyond supply rails, simplifying single-supply interfacing with transducers and ADC references. |
Pinout & Package
TLV2462AQDRQ1 is packaged in an 8-pin SOIC (D package), body size 3.91 mm × 4.90 mm, with exposed pad not present and RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable, high-impedance during shutdown, supports direct connection to SAR ADC inputs. |
| 2 | IN– A | Inverting input A - CMOS input with 14-nA max bias current at 5 V, compatible with high-impedance sensor bridges. |
| 3 | IN+ A | Noninverting input A - accepts common-mode voltages down to –0.2 V, enabling ground-referenced differential sensing. |
| 4 | GND | Negative supply reference - shared return for both channels and shutdown logic; requires low-impedance PCB plane. |
| 5 | IN+ B | Noninverting input B - electrically isolated from Channel A; supports independent signal paths in dual-sensor systems. |
| 6 | IN– B | Inverting input B - matched input characteristics to Channel A, enabling consistent gain and offset across dual channels. |
| 7 | OUT B | Amplifier B output - identical AC/DC performance to OUT A; allows simultaneous buffering of two analog signals. |
| 8 | VDD+ | Positive supply - operates from 2.7 V to 6 V; internal regulation ensures stable biasing across automotive battery transients. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation, meeting automotive powertrain and body electronics thermal requirements. |
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3-V or 5-V single-supply systems without level-shifting circuitry. |
| Channel-independent shutdown | Per-channel SHDN control (pin 8) allows selective power gating - e.g., disable Channel B while keeping A active for wake-up monitoring. |
| Low input noise voltage | 11 nV/√Hz at 1 kHz supports high-fidelity amplification of microvolt-level signals from thermocouples or strain gauges. |
| High output current drive | ±80-mA capability eliminates need for external buffers when driving 10-kΩ loads or charging 100-pF sampling capacitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462QDRQ1 | Standard version without 'A' grade; input offset voltage up to 2000 μV (max) vs. 1700 μV (max) for TLV2462AQDRQ1. | Acceptable for non-precision functions like LED biasing or coarse sensor gain stages where offset drift is less critical. | Select TLV2462QDRQ1 only when cost sensitivity outweighs 10× higher offset tolerance requirement. |
| LM7332QMA/NOPB | Higher slew rate (10 V/μs), wider supply range (2.7–36 V), but no shutdown function and higher 2.3-mA/channel supply current. | Better suited for high-speed motor control loops or wide-input-range industrial sensors, not low-power automotive sleep modes. | Choose LM7332QMA/NOPB when bandwidth >10 MHz or supply >6 V is required; avoid if shutdown or sub-1-mA IQ is mandatory. |

FAQ
What is the operating temperature range for TLV2462AQDRQ1?
The TLV2462AQDRQ1 is qualified per AEC-Q100 Grade 1 with an ambient operating temperature range of –40°C to +125°C. This specification is validated across all electrical parameters in the datasheet, including input offset voltage, CMRR, and supply current, ensuring reliable operation in engine bay and powertrain environments where thermal stress is extreme.
Does TLV2462AQDRQ1 support true rail-to-rail input and output?
Yes, TLV2462AQDRQ1 supports rail-to-rail input (common-mode range extends to –0.2 V and VDD + 0.2 V) and rail-to-rail output (swings within 10 mV of VDD and GND at ±40-mA load). This capability is confirmed in Section 6.3 (Recommended Operating Conditions) and Figure 5–8 of the datasheet, enabling single-supply operation without external level-shifting components.
What is the shutdown behavior of TLV2462AQDRQ1?
When the SHDN pin (Pin 8) is driven below 0.7 V, TLV2462AQDRQ1 enters shutdown mode with supply current reduced to ≤1 μA per channel and outputs placed in high-impedance state. The device resumes normal operation within 7.6 μs after SHDN rises above 2 V, as verified in Section 6.11 (Operating Characteristics) and Figure 22–25 of the datasheet.
How does TLV2462AQDRQ1 differ from TLV2462QDRQ1?
TLV2462AQDRQ1 is the 'A' grade variant with tighter input offset voltage specifications: 150–1500 μV (typ/max) vs. 100–2000 μV for TLV2462QDRQ1 at 25°C. It also features improved temperature coefficient (2 μV/°C) and enhanced CMRR (85 dB typ), making TLV2462AQDRQ1 preferred for precision automotive sensing where DC accuracy is critical.
Is TLV2462AQDRQ1 pin-compatible with other packages in the TLV2462-Q1 family?
TLV2462AQDRQ1 (SOIC-8, D package) shares identical pinout with TLV2462AQDGKRQ1 (VSSOP-8) and TLV2462AQPWPRQ1 (TSSOP-8), as confirmed in Section 5 (Pin Configuration and Functions) of the datasheet. All three variants use Pin 1 = OUT A, Pin 2 = IN– A, Pin 3 = IN+ A, Pin 4 = GND, Pin 5 = IN+ B, Pin 6 = IN– B, Pin 7 = OUT B, Pin 8 = VDD+, with no NC pins.
