Product details
Overview
TLV2462AQDG4 from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier designed for low-voltage 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 - enabling high-fidelity buffering of ADC inputs in battery-powered systems.
For engineers reviewing the TLV2462AQDG4 datasheet, TLV2462AQDG4 pinout, TLV2462AQDG4 application, or TLV2462AQDG4 equivalent, this device is selected for precision analog front-ends where rail-to-rail swing, low quiescent current, and AEC-Q100-compliant temperature operation (−40°C to 125°C) are required in space-constrained designs.
Technical Context
The TLV2462AQDG4 employs complementary input stage architecture enabling true rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing with high-current capability. Its 6.4 MHz bandwidth and 1.6 V/µs slew rate support stable unity-gain buffer configurations driving capacitive loads up to 160 pF.
Each channel integrates independent shutdown control (SHDN pin), reducing supply current to 0.3 µA/channel while placing the output in high-impedance state. The device operates from 2.7 V to 6 V single supply or ±1.35 V to ±3 V split supply, meeting Q-temp automotive qualification requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable closed-loop gain up to 10 at 640 kHz without phase margin degradation. |
| Slew Rate | 1.6 V/µs - enables accurate reproduction of 100-kHz, 1-Vpp signals with <0.1% distortion. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤1 LSB error when buffering 12-bit ADCs with 2.5 V reference. |
| Supply Current per Channel | 500 µA - allows dual op-amp operation from coin-cell or energy-harvesting sources. |
| Rail-to-Rail I/O | Input range: 0 V to VDD; Output swing: within 100 mV of rails at ±10 mA load - maximizes dynamic range in 3.3 V systems. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% versus active mode. |
| Input Noise Voltage | 11 nV/√Hz at 1 kHz - preserves SNR in sensor amplification chains with bandwidth <100 kHz. |
Pinout & Package
TLV2462AQDG4 is housed in an 8-pin MSOP (DGK) package with exposed thermal pad, optimized for thermal performance in automotive PCB layouts. Pin 1 is marked by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers rail-to-rail buffered signal; capable of sourcing/sinking ±80 mA. |
| 2 (IN− A) | Channel A inverting input | Differential input node; supports common-mode range from 0 V to VDD. |
| 3 (IN+ A) | Channel A non-inverting input | Differential input node; matched bias current minimizes offset drift. |
| 4 (GND) | Analog ground reference | Primary return path for both channels; must be connected to low-impedance system ground plane. |
| 5 (SHDN A) | Channel A shutdown control | Active-low logic input; <0.7 V disables channel, >2 V enables; independent of Channel B. |
| 6 (VDD+) | Positive supply rail | Accepts 2.7–6 V single supply or +VDD in split-supply configuration. |
| 7 (OUT B) | Channel B output | Independent rail-to-rail output; identical drive capability to OUT A. |
| 8 (IN− B) | Channel B inverting input | Electrically isolated from Channel A; supports separate feedback networks. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3 V supply in ADC driver applications without level-shifting circuitry. |
| 6.4 MHz GBW with 1.6 V/µs slew rate | Supports unity-gain stable operation driving 10 kΩ || 160 pF loads typical of SAR ADC input networks. |
| 0.3 µA/channel shutdown current | Reduces total system standby current to sub-µA levels when paired with microcontroller GPIO control. |
| AEC-Q100 qualified (Grade 2) | Rated for −40°C to 125°C ambient operation with production test coverage per automotive reliability standards. |

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 |
|---|---|---|---|
| TLV2462IDR | Same architecture and specs, but rated for −40°C to 125°C industrial temp range (not AEC-Q100 qualified); no automotive qualification documentation. | Lacks Q-temp automotive qualification and configuration control; unsuitable for safety-critical vehicle subsystems. | Select TLV2462IDR only for cost-sensitive industrial designs where automotive qualification is not mandated. |
| LMV722QMG/NOPB | Lower GBW (10 MHz) and higher supply current (1.25 mA/ch); no shutdown function; same 8-pin MSOP package. | Higher power consumption precludes use in battery-operated systems; absence of shutdown prevents deep-sleep modes. | Choose LMV722QMG/NOPB when higher speed is needed and shutdown is unnecessary, but verify thermal dissipation in compact enclosures. |
Compared with TLV2462AQDG4, TLV2462IDR offers identical electrical performance but lacks automotive qualification and traceability controls, while LMV722QMG/NOPB trades shutdown capability and micropower operation for increased bandwidth - making TLV2462AQDG4 the sole option for AEC-Q100-compliant, low-quiescent dual op-amps in space-constrained automotive modules.

FAQ
What is the operating temperature range for TLV2462AQDG4?
The TLV2462AQDG4 is qualified for operation from −40°C to 125°C ambient temperature and meets AEC-Q100 Grade 2 requirements. This rating is verified per TI's Q-temp automotive qualification program and applies across the full specified supply range (2.7 V to 6 V). The device undergoes production testing at temperature extremes to ensure parametric compliance throughout this range.
Does TLV2462AQDG4 support true rail-to-rail input and output?
Yes, TLV2462AQDG4 supports true rail-to-rail input common-mode voltage range (0 V to VDD) and rail-to-rail output swing (within 100 mV of rails at ±10 mA load). This is achieved via complementary input transistor pairs and Class AB output stage design - confirmed in the Electrical Characteristics tables for VOH/VOL across supply voltages and load conditions.
How does the shutdown feature work on TLV2462AQDG4?
TLV2462AQDG4 provides independent shutdown control for each channel via dedicated SHDN pins (Pin 5 for Channel A, Pin 8 for Channel B). Driving SHDN <0.7 V places the corresponding amplifier in ultralow-current mode (0.3 µA/channel) and forces its output into high-impedance state. SHDN >2 V enables normal operation - behavior validated in the Electrical Characteristics table under IDD(SHDN).
What package type is used for TLV2462AQDG4?
TLV2462AQDG4 is packaged in an 8-pin MSOP (DGK) with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm. The "DG4" suffix explicitly denotes this MSOP-8 package variant per TI's part numbering convention, and pinout matches the standard DGK footprint shown in Figure 4 of SLOS220J.
Is TLV2462AQDG4 pin-compatible with other TLV246x variants?
TLV2462AQDG4 is pin-compatible with TLV2462IDR and TLV2462CDR in the same MSOP-8 (DGK) package, sharing identical pin assignments for IN+, IN−, OUT, GND, VDD+, and SHDN per channel. However, it is not pin-compatible with TLV2462AID (SOIC-8) or TLV2462AIP (PDIP-8), which use different footprints and pinouts.
