Product details
Overview
TLV2462QPWRG4 from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier designed for low-voltage, high-precision signal conditioning in automotive and industrial systems. 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 - enabling accurate buffering of ADC inputs in 2.7–6 V systems.
For engineers reviewing the TLV2462QPWRG4 datasheet, TLV2462QPWRG4 pinout, TLV2462QPWRG4 application, or TLV2462QPWRG4 equivalent, key selection criteria include its Q-temp automotive qualification (−40°C to 125°C), shutdown capability (0.3 µA/channel), rail-to-rail swing, low noise (11 nV/√Hz at 1 kHz), and TSSOP-8 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2462QPWRG4 implements a CMOS input stage with rail-to-rail common-mode input range extending beyond supply rails and rail-to-rail output swing delivering full dynamic range in single-supply configurations. Its internal architecture supports stable unity-gain operation with 45° phase margin at 10 kΩ load and 160 pF capacitance.
It integrates independent shutdown control per channel (SHDN pins 1 and 8), placing each amplifier in ultralow-current mode (0.3 µA/ch) while forcing output into high-impedance state - critical for power-gated sensor interfaces and multiplexed analog front-ends in automotive ECUs.
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., G = 5) in precision sensor amplification stages. |
| Slew Rate | 1.6 V/µs - supports clean 10-bit+ ADC driving at ≥100 kSPS without slewing-induced distortion. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.001% gain error in 10 V full-scale instrumentation amplifiers. |
| Supply Current / Channel | 500 µA - allows dual op-amp operation within 1 mA total budget for battery-powered automotive sensors. |
| Output Drive | ±80 mA - drives 60 Ω loads directly (e.g., 50 Ω coax + termination) without external buffers. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - preserves SNR in low-level thermocouple or strain gauge signal chains. |
| Operating Temp Range | −40°C to 125°C - qualified per AEC-Q100 for under-hood automotive applications including engine control and ADAS front-end conditioning. |
Pinout & Package
TSSOP-8 (PW) package: 3.0 mm × 4.4 mm, 0.65 mm pitch, exposed thermal pad (not electrically connected), moisture sensitivity level 2a.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Shutdown | Active-high digital control: >2 V enables Channel 1; <0.7 V disables (0.3 µA IQ). |
| 2 | Channel 1 Inverting Input | Differential input node for Channel 1; CMVR extends to rails (0 V to VDD). |
| 3 | Channel 1 Non-Inverting Input | Differential input node for Channel 1; supports rail-to-rail common-mode input. |
| 4 | Ground | Analog ground reference for both channels and shutdown logic. |
| 5 | Channel 2 Non-Inverting Input | Differential input node for Channel 2; independent of Channel 1 biasing. |
| 6 | Channel 2 Inverting Input | Differential input node for Channel 2; fully decoupled from Channel 1 path. |
| 7 | Channel 2 Output | Rail-to-rail output capable of sourcing/sinking ±80 mA into resistive loads. |
| 8 | VDD+ | Positive supply rail (2.7–6 V); powers both amplifiers and shutdown circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full utilization of 3.3 V or 5 V ADC reference spans without level-shifting circuitry. |
| Q-temp Automotive Qualification | Qualified to −40°C to 125°C ambient per AEC-Q100, supporting under-hood ECU deployment. |
| Independent Dual Shutdown | Per-channel SHDN pins allow selective power gating - e.g., disable idle channel in multiplexed sensor arrays. |
| Low Input Offset Drift | 2 µV/°C max - maintains calibration integrity across automotive temperature cycles without software compensation. |
| High CMRR & PSRR | 85 dB CMRR and 85 dB PSRR (min) - rejects engine noise coupling and supply ripple in noisy vehicle 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, commercial temp range (−40°C to 85°C), non-automotive qualification. | Lacks AEC-Q100 validation; unsuitable for under-hood automotive use but lower cost for industrial prototypes. | Select when automotive qualification is not required and cost sensitivity outweighs extended temperature margin. |
| OPA2333AIPW | Zero-drift architecture (0.02 µV/°C offset drift), lower noise (5.5 nV/√Hz), higher IQ (17 µA/ch), no shutdown. | Better DC precision but higher power; no shutdown limits use in ultra-low-power duty-cycled systems. | Select when long-term offset stability dominates over shutdown capability and quiescent current. |
Compared with TLV2462QPWRG4, TLV2462IPW offers identical AC performance at lower cost but lacks automotive qualification, while OPA2333AIPW trades shutdown and micropower for superior DC accuracy - making TLV2462QPWRG4 optimal for cost-sensitive, temperature-rugged, power-gated dual-op-amp roles.

FAQ
What is the operating temperature range for TLV2462QPWRG4?
The TLV2462QPWRG4 is qualified for operation from −40°C to 125°C ambient temperature and meets AEC-Q100 Grade 2 requirements for automotive applications. This rating is confirmed in the device's Q-suffix specification table and absolute maximum ratings section of the SLOS220J datasheet.
Does TLV2462QPWRG4 support true rail-to-rail input and output?
Yes, TLV2462QPWRG4 provides rail-to-rail input common-mode voltage range (0 V to VDD) and rail-to-rail output swing (within 10 mV of rails at 10 mA load). This is explicitly stated in the device description and verified in electrical characteristics tables for VOH/VOL across supply voltages.
How does the shutdown function work on TLV2462QPWRG4?
TLV2462QPWRG4 features two independent shutdown pins (Pin 1 for Channel 1, Pin 8 for Channel 2). Driving either pin below 0.7 V places its respective amplifier into ultralow-current mode (0.3 µA/channel), and forces the output into high-impedance state - confirmed in the shutdown supply current specifications and functional description.
What package type is used for TLV2462QPWRG4?
TLV2462QPWRG4 uses the TSSOP-8 (PW) package: 3.0 mm × 4.4 mm body, 0.65 mm lead pitch, with an exposed thermal pad (non-connected). This is documented in the "TLV2462M/AM/Q/AQ AVAILABLE OPTIONS" table and package pinout diagrams in the SLOS220J datasheet.
Is TLV2462QPWRG4 pin-compatible with other TLV246x variants in TSSOP-8?
Yes - all TLV246x dual-amplifier variants in the PW package (including TLV2462C, TLV2462I, TLV2462A, and TLV2462Q) share identical TSSOP-8 pinouts per the "TLV246x PACKAGE PINOUTS" section. Pin functions (e.g., SHDN, IN+, OUT) are consistent across the family in this package.
