Product details
Overview
TLV2462QDRG4 from Texas Instruments is a dual rail-to-rail input/output operational amplifier designed for low-power, 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 single-supply applications.
For engineers reviewing the TLV2462QDRG4 datasheet, TLV2462QDRG4 pinout, TLV2462QDRG4 application, or TLV2462QDRG4 equivalent, key selection criteria include its Q-temp automotive qualification (−40°C to 125°C), shutdown capability (0.3 µA/channel), rail-to-rail output swing, low 11 nV/√Hz input noise, and compatibility with space-constrained TSSOP-8 layouts.
Technical Context
The TLV2462QDRG4 implements a CMOS input stage with rail-to-rail common-mode input range extending beyond supply rails, supporting full dynamic range in low-voltage systems. Its output stage provides true rail-to-rail swing with high-current sourcing/sinking capability, overcoming limitations of earlier rail-to-rail op-amps.
It integrates independent shutdown control per channel (SHDN pins 1 and 8), placing each amplifier in ultralow 0.3 µA quiescent current mode while forcing output into high-impedance state - critical for power-gated sensor interfaces and battery-powered modules requiring fast wake-up (<8 µs turn-on time).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 6.4 MHz - supports stable unity-gain buffer operation up to ~6 MHz with minimal phase margin degradation. |
| Slew rate | 1.6 V/µs - enables clean reproduction of 1-Vpp signals up to ~250 kHz without slew-induced distortion. |
| Supply current per channel | 500 µA - allows dual-channel precision amplification in sub-1-mA system power budgets. |
| Input offset voltage | 100 µV (typ) - ensures ≤0.01% gain error in 1-V full-scale instrumentation paths. |
| Output drive | ±80 mA - drives 62 Ω loads to rail while maintaining linearity, suitable for driving SAR ADC reference buffers. |
| Input noise voltage | 11 nV/√Hz @ 1 kHz - preserves SNR in 20-kHz bandwidth sensor front-ends with <1 µV RMS integrated noise. |
| Shutdown current | 0.3 µA/channel - reduces standby power by >99.9% versus active mode, ideal for duty-cycled measurement nodes. |
Pinout & Package
The TLV2462QDRG4 is housed in an 8-pin TSSOP package (PW suffix), optimized for thermal performance and board density in automotive control units.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN1) | Channel 1 shutdown control | Active-high logic input; ≥2 V enables Channel 1, ≤0.7 V disables it with high-Z output. |
| 2 (IN−1) | Inverting input, Channel 1 | Differential input node referenced to GND; supports rail-to-rail common-mode range (0–VDD). |
| 3 (IN+1) | Non-inverting input, Channel 1 | Differential input node referenced to GND; matched bias current minimizes offset drift. |
| 4 (GND) | Analog ground reference | Primary return path for input bias currents and output load currents; must be low-impedance. |
| 5 (OUT1) | Channel 1 output | Rail-to-rail output capable of sourcing/sinking ±80 mA; high-Z during shutdown. |
| 6 (OUT2) | Channel 2 output | Independent rail-to-rail output; electrically isolated from OUT1 except via shared VDD/GND. |
| 7 (IN+2) | Non-inverting input, Channel 2 | Matched to IN+1; enables dual-sensor differential amplification with common-mode rejection. |
| 8 (SHDN2) | Channel 2 shutdown control | Independent active-high control; allows asymmetric channel enablement for sequenced signal chains. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full 0–VDD input range and output swing in single-supply 2.7–6 V systems, maximizing ADC utilization. |
| Q-temp automotive qualification | Specified over −40°C to +125°C ambient, qualified to AEC-Q100 Rev-G stress test standards for engine control modules. |
| Independent dual-channel shutdown | Per-channel SHDN pins allow selective power gating - e.g., disable analog front-end during sleep while retaining CAN transceiver bias. |
| Low input noise | 11 nV/√Hz at 1 kHz supports <100-dB SNR in 10-kHz bandwidth sensor interfaces (e.g., thermocouple amplifiers). |
| High output drive | ±80 mA capability eliminates need for external buffers when driving 10-kΩ ADC inputs with 100-pF sampling capacitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Same architecture and specs but rated for −40°C to +125°C (I-suffix), not Q-temp qualified; no AEC-Q100 documentation. | Lacks automotive qualification; suitable for industrial controls but not under-hood automotive use. | Select TLV2462IDR only if AEC-Q100 compliance is unnecessary and cost is prioritized over automotive traceability. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2462QDRG4's 2 µV/°C; higher 350 µA/channel supply current. | Better DC stability for long-duration DC-coupled measurements; higher power limits use in ultra-low-power battery apps. | Choose OPA2333AIDR when microvolt-level offset stability over temperature is critical, accepting 30% higher quiescent current. |
Compared with TLV2462IDR, the TLV2462QDRG4 adds AEC-Q100 qualification and configuration control for automotive production, while OPA2333AIDR trades lower drift and higher precision for increased supply current and no shutdown function - making TLV2462QDRG4 optimal for cost-sensitive, power-gated automotive signal chains requiring proven reliability.

FAQ
What is the operating temperature range for TLV2462QDRG4?
The TLV2462QDRG4 is qualified for operation from −40°C to +125°C ambient temperature and meets AEC-Q100 Grade 2 requirements for automotive applications. This extended range is validated across all electrical parameters including input offset voltage, supply current, and output drive capability - ensuring reliable performance in engine control units and transmission control modules.
Does TLV2462QDRG4 support single-supply operation?
Yes, TLV2462QDRG4 supports true single-supply operation from 2.7 V to 6 V. Its rail-to-rail input common-mode range extends from 0 V to VDD, and its output swings within 10 mV of both rails under light loads - enabling direct interfacing with 3.3 V or 5 V ADCs without level-shifting circuitry.
How does the shutdown feature work on TLV2462QDRG4?
The TLV2462QDRG4 has two independent shutdown pins (pins 1 and 8). Driving either pin below 0.7 V disables its respective amplifier channel, reducing supply current to 0.3 µA/channel and placing the output in high-impedance state. Both channels remain active when pins are held ≥2 V - allowing flexible power sequencing in multi-stage analog signal chains.
What is the maximum capacitive load TLV2462QDRG4 can drive stably?
TLV2462QDRG4 maintains phase margin >30° with capacitive loads up to 100 pF when driving a 10-kΩ load, as confirmed in Figure 14 of the datasheet. For loads >100 pF, external series resistance (≥10 Ω) is recommended at the output to ensure stability - critical when driving ADC sampling capacitors or long PCB traces.
Is TLV2462QDRG4 pin-compatible with other TLV246x variants?
TLV2462QDRG4 uses the TSSOP-8 (PW) package and shares identical pinout with TLV2462IDR, TLV2462CDR, and TLV2462AIDR. However, it is not pin-compatible with TLV2460 (SOT-23-6), TLV2463 (MSOP-10), or TLV2464 (TSSOP-14); those variants differ in channel count, shutdown implementation, and pin count - requiring PCB redesign for substitution.
