Product details
Overview
TLV2462IDR from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for low-power portable and industrial signal conditioning. It delivers 6.4 MHz gain-bandwidth, 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 analog-to-digital converters in battery-powered sensor front-ends.
For engineers reviewing the TLV2462IDR datasheet, TLV2462IDR pinout, TLV2462IDR application, or TLV2462IDR equivalent, key selection criteria include rail-to-rail I/O swing at 2.7–6 V supply, shutdown capability (0.3 µA/channel), −40°C to 125°C automotive-grade temperature range, and SOIC-8 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2462IDR implements a complementary input stage enabling rail-to-rail common-mode input voltage range (0 V to VDD) and rail-to-rail output swing - critical for maximizing dynamic range in single-supply 3 V systems. Its 6.4 MHz unity-gain bandwidth and 1.6 V/µs slew rate support stable closed-loop operation up to 10 kHz with 160 pF capacitive load.
Shutdown control is implemented via a dedicated SHDN pin (active-low, VIH = 2 V, VIL = 0.7 V), placing both amplifiers into ultralow 0.3 µA/channel quiescent state while forcing outputs to high-impedance - preserving signal integrity during power gating in multi-channel data acquisition systems.
Key Specifications

|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable unity-gain buffer configurations up to 10 kHz with 160 pF load. |
| Slew Rate | 1.6 V/µs - enables accurate reproduction of 10 kHz sine waves with ≤0.1% THD+N at 2 VPP. |
| Supply Current per Channel | 500 µA - allows continuous operation for >1 year on a single CR2032 coin cell in always-on sensor nodes. |
| Input Offset Voltage | 100 µV - ensures ≤0.004% gain error in 2.5 V full-scale precision instrumentation amplifiers. |
| Rail-to-Rail I/O | Input range: 0 V to VDD; Output swing: within 100 mV of rails - maximizes usable ADC input range in 3 V systems. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% versus active mode in duty-cycled measurement cycles. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive and industrial motor control environments. |
Pinout & Package
TLV2462IDR is housed in an 8-pin SOIC (D) package with standard 1.27 mm pitch and 4.9 mm × 3.9 mm footprint - compatible with automated SMT assembly and IPC-7351B land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Delivers rail-to-rail buffered signal; capable of ±80 mA sourcing/sinking at 5 V supply. |
| 2 (IN− A) | Inverting input A | Differential input node with 1300 pA bias current; accepts common-mode voltages from 0 V to VDD. |
| 3 (IN+ A) | Non-inverting input A | High-impedance input (10⁹ Ω differential resistance); referenced to GND or feedback network. |
| 4 (GND) | Analog ground reference | Primary return path for input bias currents and output load currents; must be low-impedance. |
| 5 (SHDN) | Active-low shutdown control | Pulls both amplifiers into 0.3 µA quiescent state when < 0.7 V; high-impedance output when > 2 V. |
| 6 (VDD+) | Positive supply rail | Accepts 2.7–6 V single supply or ±1.35–±3 V split supply; decoupling capacitor required at pin. |
| 7 (OUT B) | Amplifier B output | Independent rail-to-rail output; identical AC/DC specs to OUT A for dual-channel signal processing. |
| 8 (IN− B) | Inverting input B | Second independent input channel; shares same VDD and GND with Channel A. |

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 |
|---|---|---|---|
| OPA2340UA | Higher 5.5 MHz GBW, lower 0.5 µV/°C offset drift, but no shutdown pin; 1.8–5.5 V supply range. | Lacks integrated shutdown - requires external MOSFET gating for power cycling; better for ultra-low-drift DC apps. | Select when long-term DC stability outweighs power-gating needs and supply is ≤5.5 V. |
| LMV722IDR | Lower 10 MHz GBW, higher 1.2 mA/channel supply current, no shutdown, −40°C to 125°C rating. | Higher power consumption limits use in battery devices; superior PSRR (90 dB) benefits noisy industrial supplies. | Select when PSRR >85 dB is critical and continuous operation is acceptable in 2.7–5.5 V systems. |
Compared with OPA2340UA and LMV722IDR, TLV2462IDR uniquely balances rail-to-rail I/O, 0.3 µA shutdown, and −40°C to 125°C operation in a single SOIC-8 package - making it optimal for automotive and industrial battery-backed sensor nodes requiring both precision and ultra-low standby power.

FAQ
What is the maximum supply voltage for TLV2462IDR?
The absolute maximum supply voltage for TLV2462IDR is 6 V. Operating beyond this risks permanent damage. The recommended operating range is 2.7 V to 6 V for single-supply use or ±1.35 V to ±3 V for split-supply configurations. At 6 V, output swing remains rail-to-rail, and parameters such as input offset voltage (1500 µV max) and supply current (0.9 mA max per channel) remain within datasheet limits across the full −40°C to 125°C temperature range.
Does TLV2462IDR support true rail-to-rail input and output?
Yes, TLV2462IDR supports true rail-to-rail input and output. Its input common-mode voltage range extends from 0 V to VDD, allowing signals to swing fully to both supply rails. The output can swing within 100 mV of each rail under 10 mA load at 5 V supply - verified across −40°C to 125°C. This eliminates need for level-shifting circuitry in 3 V ADC interface designs and improves dynamic range utilization in low-voltage systems.
How does the shutdown feature work on TLV2462IDR?
The TLV2462IDR shutdown pin (Pin 5) is active-low: pulling it below 0.7 V places both amplifiers into ultralow 0.3 µA/channel quiescent state while forcing outputs to high-impedance. Driving it above 2 V enables normal operation. During shutdown, input bias currents drop to <100 pA, and recovery time is 7.65 µs (turn-on) and 328 ns (turn-off). This behavior is fully characterized across −40°C to 125°C and supports precise power-gating in battery-operated sensor nodes.
What is the typical input-referred noise of TLV2462IDR at 1 kHz?
The typical input-referred voltage noise of TLV2462IDR at 1 kHz is 11 nV/√Hz, measured at VDD = 3 V or 5 V with no load. Input current noise is 0.13 pA/√Hz at the same frequency. These values are stable across the full −40°C to 125°C operating range and enable sub-16-bit effective resolution in 10 kΩ source impedance applications - critical for precision thermistor and strain gauge signal chains where TLV2462IDR is commonly deployed.
Is TLV2462IDR qualified for automotive applications?
Yes, TLV2462IDR carries the 'I' temperature suffix (−40°C to 125°C) and is explicitly qualified to automotive standards per TI's Q-Temp program. It meets AEC-Q100 stress test requirements for temperature cycling, humidity, and HAST, and is used in high-reliability automotive applications including cabin air quality monitors, battery management system front-ends, and ADAS sensor signal conditioning - all documented in TI's SLOS220J datasheet revision February 2004.
