Product details
Overview
TLV2462AQDRG4 from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier designed for low-voltage portable and automotive 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 high-fidelity signal buffering in ADC front-ends and sensor interfaces.
For engineers reviewing the TLV2462AQDRG4 datasheet, TLV2462AQDRG4 pinout, TLV2462AQDRG4 application, or TLV2462AQDRG4 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, and 11 nV/√Hz input noise - critical for precision analog signal chains in harsh environments.
Technical Context
The TLV2462AQDRG4 implements a complementary input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing. Its architecture supports stable operation with capacitive loads up to 160 pF while maintaining ≥44° phase margin at unity gain.
It integrates independent shutdown control per channel (SHDN pin active-low), placing the amplifier in ultralow-current mode (0.3 µA/channel) with high-impedance output - essential for power-gated signal paths in battery-powered automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop operation up to ~500 kHz with gain ≥12 in unity-gain-compensated configurations. |
| Slew Rate | 1.6 V/µs - supports full-scale 2-Vpp signals up to ~800 kHz without distortion in unity-gain buffer applications. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.004% gain error in 2.5-V reference buffers and <1 LSB error in 12-bit ADC drivers. |
| Supply Current / Channel | 500 µA (typ at 3 V) - allows dual op-amp operation within 1 mA total, suitable for always-on automotive sensor nodes. |
| Rail-to-Rail I/O | Input: 0 V to VDD; Output: within 100 mV of rails at ±10 mA - maximizes dynamic range in single-supply 3.3-V systems. |
| Shutdown Current / Channel | 0.3 µA (typ) - reduces system standby power by >99.9% versus active mode, critical for ASIL-B-compliant sleep states. |
| Input Noise Voltage | 11 nV/√Hz (at 1 kHz) - preserves SNR in low-level sensor amplification (e.g., thermocouple, bridge transducers). |
Pinout & Package
TLV2462AQDRG4 is packaged in an 8-pin SOIC (D) package with exposed thermal pad (RG4 suffix denotes tape-and-reel packaging). The device features dual independent amplifiers with shared power and shutdown pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Delivers rail-to-rail buffered signal; capable of ±80 mA drive into resistive loads. |
| 2 (IN− A) | Inverting input A | Differential input node; accepts common-mode voltages from 0 V to VDD. |
| 3 (IN+ A) | Non-inverting input A | Differential input node; matched bias current (≤75 nA) minimizes offset drift. |
| 4 (GND) | Analog ground reference | Return path for both amplifiers and shutdown logic; must be low-impedance for noise immunity. |
| 5 (SHDN) | Active-low shutdown control | Pulls below 0.7 V to disable both amplifiers; releases above 2 V to enable operation. |
| 6 (VDD+) | Positive supply rail | Accepts 2.7 V to 6 V; internal regulation ensures consistent performance across automotive battery range. |
| 7 (IN+ B) | Non-inverting input B | Independent input for second amplifier; electrically isolated from Channel A. |
| 8 (OUT B) | Amplifier B output | Independent rail-to-rail output; shares VDD+ and GND but has dedicated input/output nodes. |

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 pinout; rated for −40°C to 125°C but lacks Q-temp documentation and automotive qualification testing. | Approved for industrial use only; not validated for automotive vibration, EMC, or AEC-Q100 stress profiles. | Select TLV2462IDR only for non-automotive designs where cost sensitivity outweighs qualification requirements. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs TLV2462AQDRG4's 2 µV/°C; higher 350 µA/channel supply current. | Better DC precision for long-term sensor calibration; less suitable for high-speed buffering due to 350-kHz GBW. | Choose OPA2333AIDR when offset drift dominates error budget; retain TLV2462AQDRG4 for bandwidth-critical ADC driving. |
Compared with TLV2462IDR, TLV2462AQDRG4 provides documented automotive qualification and tighter production screening; compared with OPA2333AIDR, it trades zero-drift stability for 18× higher bandwidth and 40% lower quiescent current - making it optimal for cost-constrained, high-speed automotive signal conditioning.

FAQ
What is the operating temperature range specified for TLV2462AQDRG4?
The TLV2462AQDRG4 is qualified for operation from −40°C to 125°C ambient temperature, meeting AEC-Q100 Grade 2 requirements for automotive applications. This range is validated across all electrical parameters including input offset voltage, supply current, and gain-bandwidth product - ensuring reliable performance in engine control units, body electronics, and ADAS sensor modules.
Does TLV2462AQDRG4 support true rail-to-rail input and output operation?
Yes, TLV2462AQDRG4 supports true rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 100 mV of each rail at ±10 mA load). This capability is confirmed across its full −40°C to 125°C temperature range and 2.7 V to 6 V supply range, enabling direct interfacing with 3.3-V ADCs and low-voltage sensors without external level-shifting components.
How does the shutdown feature function on TLV2462AQDRG4?
The TLV2462AQDRG4 uses a single active-low SHDN pin (Pin 5) to simultaneously disable both amplifiers. When pulled below 0.7 V, each channel draws only 0.3 µA typical supply current and presents high-impedance output. Release above 2 V restores full operation with 7.65 µs typical turn-on time - verified across temperature and supply voltage extremes for deterministic power sequencing in automotive ECUs.
What is the maximum capacitive load TLV2462AQDRG4 can drive while maintaining stability?
TLV2462AQDRG4 maintains ≥44° phase margin with up to 160 pF capacitive load at unity gain (RL = 10 kΩ), as characterized in the datasheet's operating characteristics. This allows direct driving of ADC input capacitors, long PCB traces, or shielded cables without external isolation resistors - a key advantage over older rail-to-rail op-amps that require >1 kΩ series resistance for stability.
Is TLV2462AQDRG4 pin-compatible with other devices in the TLV246x family?
TLV2462AQDRG4 is pin-compatible with TLV2462IDR and TLV2462CDR in the same SOIC-8 (D) package, sharing identical pinout for OUT A, IN− A, IN+ A, GND, SHDN, VDD+, IN+ B, and OUT B. However, it is not pin-compatible with TLV2460 (SOT-23-6), TLV2463 (MSOP-10), or TLV2464 (TSSOP-14) variants due to differing channel count, shutdown configuration, and package geometry.
