Product details
Overview
TLV2462QDRG4Q1 from Texas Instruments is a dual-channel, automotive-grade rail-to-rail input/output operational amplifier with shutdown capability, 6.4 MHz gain-bandwidth product, 1.6 V/μs slew rate, ±80-mA output drive, and 500 μA/channel supply current. It operates from 2.7 V to 6 V and is qualified for AEC-Q100 Grade 1 (–40°C to +125°C), targeting battery management and lighting modules in HEV/EV powertrain systems.
For engineers reviewing the TLV2462QDRG4Q1 datasheet, TLV2462QDRG4Q1 pinout, TLV2462QDRG4Q1 application, or TLV2462QDRG4Q1 equivalent, key selection criteria include rail-to-rail I/O swing, ultra-low shutdown current (0.3 μA/channel), input offset voltage ≤2000 μV over temperature, ESD robustness (HBM ±2000 V), and SOIC-8 packaging compatibility with automotive thermal requirements.
Technical Context
The TLV2462QDRG4Q1 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.
It features independent channel shutdown control via SHDN pin (Pin 5), placing each amplifier in high-impedance output state while drawing only 0.3 μA per channel. Input noise voltage is 11 nV/√Hz at 1 kHz, and large-signal differential voltage amplification exceeds 92 dB at 5 V supply.
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 |
| Slew rate | 1.6 V/μs - supports 100-kHz full-power signal bandwidth for 16-Vpp outputs |
| Supply current per channel | 0.55 mA typical at 5 V - enables low-quiescent-power sensor front-ends and battery monitoring |
| Output drive | ±80 mA - drives heavy capacitive loads or low-impedance ADC inputs without external buffers |
| Input offset voltage | ≤2200 μV over –40°C to +125°C - ensures <0.1% error in 2.5-V reference buffering |
| Common-mode input range | –0.2 V to VDD + 0.2 V - allows direct sensing of signals near ground or supply rails |
| Shutdown current | 0.3 μA per channel - reduces system standby power in multi-amplifier configurations |
Pinout & Package
TLV2462QDRG4Q1 is packaged in an 8-pin SOIC (D package) with body size 3.91 mm × 4.90 mm, rated for surface-mount reflow and automotive under-hood environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable, high-impedance during shutdown |
| 2 | IN– A | Inverting input, Channel A - CMOS input with bias current <14 nA at 125°C |
| 3 | IN+ A | Noninverting input, Channel A - supports common-mode range beyond rails |
| 4 | GND | Negative supply reference - must be low-impedance for noise-sensitive analog paths |
| 5 | SHDN | Active-low shutdown control - pulls below 0.7 V to disable both channels |
| 6 | IN– B | Inverting input, Channel B - electrically isolated from Channel A except shared supply |
| 7 | IN+ B | Noninverting input, Channel B - identical input characteristics to Channel A |
| 8 | VDD+ | Positive supply - accepts 2.7 V to 6 V; decoupling capacitor required at pin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462QDRQ1 | No G4 suffix; same SOIC-8 package, identical electrical specs, but lacks TI's enhanced green (lead-free, RoHS-compliant) finish | Acceptable where RoHS exemption applies; not suitable for new automotive designs requiring full environmental compliance | Select TLV2462QDRG4Q1 when lead-free assembly and full AEC-Q100 documentation traceability are mandatory |
| LM7332QMA/NOPB | Higher supply current (2.1 mA/ch), wider supply range (±2.5 V to ±16 V), no shutdown function, higher ESD (±4000 V HBM) | Better suited for high-voltage industrial sensors; unsuitable for ultra-low-power shutdown scenarios | Choose LM7332QMA/NOPB only if dual ±15-V operation or higher output current (±100 mA) is required |
Compared with TLV2462QDRQ1, TLV2462QDRG4Q1 adds RoHS-compliant finish and full green manufacturing documentation; compared with LM7332QMA/NOPB, it delivers 76% lower quiescent power and integrated shutdown-critical for battery-constrained automotive subsystems.

FAQ
What is the operating temperature range for TLV2462QDRG4Q1?
The TLV2462QDRG4Q1 is qualified per AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. This range is validated for automotive powertrain and chassis applications, with thermal metrics including RθJA = 120.1°C/W for the SOIC-8 (D) package. All electrical specifications in the datasheet are guaranteed across this full range.
Does TLV2462QDRG4Q1 support true rail-to-rail input and output?
Yes, TLV2462QDRG4Q1 supports rail-to-rail input (common-mode range from –0.2 V to VDD + 0.2 V) and rail-to-rail output (swings within 10 mV of VDD and GND at ±10 mA load). This is achieved via complementary CMOS input stage and Class AB output stage, enabling direct interface with 3.3-V or 5-V microcontrollers and ADCs without external level-shifting components.
How does the shutdown feature work on TLV2462QDRG4Q1?
The TLV2462QDRG4Q1 uses Pin 5 (SHDN) as an active-low control: pulling SHDN ≤ 0.7 V disables both amplifiers, reducing supply current to 0.3 μA per channel and placing outputs in high-impedance state. When SHDN ≥ 2 V, both channels operate normally. No external pull-up is required, but a 10-kΩ pull-up to VDD ensures defined state during power-up.
What is the maximum capacitive load TLV2462QDRG4Q1 can drive stably?
TLV2462QDRG4Q1 maintains stability with up to 160 pF capacitive load at unity gain, as verified by 45° phase margin in the datasheet. For loads >100 pF, TI recommends adding a 10-Ω isolation resistor in series with the output. Driving heavier loads (e.g., >500 pF) requires external compensation or buffer stages to prevent peaking or oscillation.
Is TLV2462QDRG4Q1 pin-compatible with other TLV246x-Q1 variants?
TLV2462QDRG4Q1 in SOIC-8 (D) package shares identical pinout with TLV2462QDRQ1 and TLV2462A-Q1 variants in the same package. However, TLV2460-Q1 (single), TLV2463-Q1 (quad), and TSSOP/VSSOP variants use different pin mappings. Always verify package marking and datasheet revision before substitution.
