Product details
Overview
TLV2462QPWR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier designed for low-power portable and automotive signal conditioning. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage. Its Q-temp automotive qualification (−40°C to 125°C) and shutdown capability make it suitable for ADC buffering and sensor front-end circuits in engine control units.
For engineers reviewing the TLV2462QPWR datasheet, TLV2462QPWR pinout, TLV2462QPWR application, or TLV2462QPWR equivalent, key selection criteria include rail-to-rail I/O swing at 2.7–6 V supply, micropower shutdown (0.3 µA/channel), low 11 nV/√Hz input noise, and TSSOP-8 packaging compatible with high-density automotive PCB layouts.
Technical Context
The TLV2462QPWR implements a CMOS input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing within 10 mV of each rail under load. Its internal architecture supports stable unity-gain operation with 45° phase margin at 160 pF capacitive load and 10 kΩ load resistance.
It integrates independent shutdown control per channel (active-low SHDN pins), placing each amplifier in ultralow-current mode (0.3 µA/channel) while forcing its output into high-impedance state-critical for power-gated analog subsystems in battery-powered automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - Enables stable closed-loop gain up to 10× at 640 kHz for anti-aliasing filter interfaces. |
| Slew Rate | 1.6 V/µs - Supports 12-bit ADC sampling at ≥100 kSPS with <0.1% distortion in buffer configurations. |
| Supply Current | 500 µA/channel - Allows continuous operation in always-on vehicle subsystems with sub-1 mA total quiescent draw. |
| Input Offset Voltage | 100 µV - Ensures ≤0.0025% full-scale error in 4–20 mA transmitter output stages. |
| Output Drive | ±80 mA - Drives 50 Ω coaxial lines or multiple SAR ADC reference inputs without external buffers. |
| Rail-to-Rail I/O | 0 V to VDD input range; output swings to within 10 mV of rails - Maximizes dynamic range in single-supply 3.3 V systems. |
| Shutdown Current | 0.3 µA/channel - Reduces system standby power by >99.9% versus active mode in infotainment wake-on-event circuits. |
Pinout & Package
TSSOP-8 package (PW suffix), 3.0 mm × 4.4 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | High-drive rail-to-rail output capable of sourcing/sinking ±80 mA; connects directly to ADC input or transducer load. |
| 2 (IN− A) | Channel A inverting input | Differential input node for precision instrumentation amplifier configurations; CMOS input draws <75 nA bias current. |
| 3 (IN+ A) | Channel A non-inverting input | High-impedance node for sensor voltage sensing; supports rail-to-rail common-mode range (0 V to VDD). |
| 4 (GND) | Analog ground reference | Primary return path for both channels; must be tied to low-impedance system ground plane to minimize PSRR degradation. |
| 5 (IN+ B) | Channel B non-inverting input | Independent input for dual-sensor monitoring (e.g., temperature + pressure); shares no internal coupling with Channel A. |
| 6 (IN− B) | Channel B inverting input | Configurable as summing node or feedback point; matched offset and bias specs ensure channel-to-channel tracking. |
| 7 (OUT B) | Channel B output | Functionally identical to Pin 1; enables dual-channel signal conditioning without inter-channel crosstalk. |
| 8 (VDD+) | Positive supply rail | Accepts 2.7–6 V single supply or ±1.35–±3 V split supply; internal regulation ensures stable operation across automotive battery transients. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3 V ADC reference range without level-shifting circuitry. |
| Q-temp automotive qualification | Guaranteed operation from −40°C to 125°C ambient, qualified to AEC-Q100 Rev G stress test requirements. |
| Independent per-channel shutdown | Allows selective power gating of one op-amp while maintaining active signal path on the other-reducing system-level power by 50%. |
| Low input voltage noise | 11 nV/√Hz at 1 kHz enables accurate amplification of µV-level thermocouple or strain gauge signals. |
| High open-loop gain | 105 dB typical ensures <0.001% gain error in precision voltage follower and PGA applications. |
| Robust ESD protection | ±2 kV HBM rating protects against assembly handling and in-system electrostatic discharge in unshielded harness environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IPW | Same silicon, industrial temp range (−40°C to 125°C), same TSSOP-8 package, but lacks Q-temp qualification and automotive PPAP documentation support. | Approved for industrial automation but not certified for under-hood automotive use per AEC-Q100. | Select TLV2462IPW only for non-automotive applications where cost sensitivity outweighs automotive compliance requirements. |
| LM7332MA/NOPB | Higher supply current (1.3 mA/channel), wider supply range (2.7–36 V), no shutdown function, higher offset (1500 µV), but higher output drive (±100 mA). | Used in 24 V commercial vehicle subsystems where rail-to-rail I/O is less critical than wide-voltage tolerance. | Choose LM7332MA/NOPB when interfacing with legacy 24 V sensors or when shutdown functionality is unnecessary and higher drive is required. |
Compared with TLV2462QPWR, TLV2462IPW offers identical electrical performance but lacks automotive qualification documentation and process controls, while LM7332MA/NOPB trades micropower operation and precision for wider supply range and higher output current-making TLV2462QPWR optimal for space-constrained, battery-sensitive automotive signal chains.

FAQ
What is the operating temperature range for TLV2462QPWR?
The TLV2462QPWR is qualified for operation from −40°C to 125°C ambient temperature and is manufactured under Texas Instruments' Q-temp automotive process, meeting AEC-Q100 reliability standards for under-hood deployment. This range is explicitly confirmed in the "Recommended Operating Conditions" table of the SLOS220J datasheet, with full electrical specifications guaranteed across the entire interval.
Does TLV2462QPWR support true rail-to-rail input and output?
Yes, TLV2462QPWR supports rail-to-rail input common-mode voltage range (0 V to VDD) and rail-to-rail output swing (within 10 mV of each rail at ±10 mA load). This is verified in the "Electrical Characteristics" section of the datasheet, where VOH ≥ VDD − 0.01 V and VOL ≤ 0.01 V are specified at VDD = 3 V and 5 V, enabling full dynamic range utilization in single-supply 3.3 V systems.
How does the shutdown feature work on TLV2462QPWR?
The TLV2462QPWR features two independent active-low shutdown pins (Pin 5 for Channel A, Pin 6 for Channel B per TSSOP-8 pinout). When pulled below 0.7 V, each channel enters ultralow-current mode (0.3 µA/channel) and its output transitions to high-impedance state-verified in the "Electrical Characteristics" table under IDD(SHDN). This allows selective power gating without affecting the other channel's operation.
What is the maximum capacitive load TLV2462QPWR can drive stably?
TLV2462QPWR maintains stability with up to 160 pF capacitive load when driving a 10 kΩ resistive load, as confirmed by 45° phase margin measurements in the "Operating Characteristics" section (Figure 36). Driving larger loads requires external isolation resistor (≥10 Ω) between output and capacitance to prevent peaking or oscillation in sensor interface or ADC buffer applications.
Is TLV2462QPWR pin-compatible with other devices in the TLV246x family?
No-TLV2462QPWR uses an 8-pin TSSOP (PW) package with dedicated IN+ B and IN− B pins, whereas TLV2460 (SOT-23-6) and TLV2461 (SOIC-8) have different pinouts and channel counts. The TLV2462QPWR pin assignment is unique to the dual-channel TSSOP variant and is not interchangeable with TLV2463 (MSOP-10) or TLV2464 (TSSOP-14) without PCB redesign.
