Product details
Overview
TLV2462AIP from Texas Instruments is a dual 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, 100 µV max input offset voltage (A-grade), and 500 µA/channel supply current across −40°C to 125°C. It buffers ADC front-ends in battery-powered data acquisition systems.
For engineers reviewing the TLV2462AIP datasheet, TLV2462AIP pinout, TLV2462AIP application, or TLV2462AIP equivalent, key selection criteria include rail-to-rail I/O swing at 2.7–6 V supply, shutdown capability (0.3 µA/channel), low noise (11 nV/√Hz), and A-grade precision for industrial sensor interfaces and automotive body control modules.
Technical Context
The TLV2462AIP integrates two independent op-amps with complementary-input-stage architecture enabling true rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing. Its 6.4 MHz GBW and 1.6 V/µs slew rate support stable unity-gain buffer operation into capacitive loads up to 160 pF.
Each channel features an active-low SHDN pin that places the amplifier in ultralow-current mode (0.3 µA/channel) while forcing output to high-impedance state. Input bias current remains below 1300 pA, supporting high-impedance sensor interfacing without significant error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V single supply - enables direct interface with Li-ion batteries and 3.3 V/5 V logic rails. |
| Gain-Bandwidth Product | 6.4 MHz - supports stable closed-loop gain ≥10 at audio and low-MHz signal frequencies. |
| Slew Rate | 1.6 V/µs - ensures <1.8 µs settling to 0.01% for 2 V step inputs, suitable for fast-settling ADC drivers. |
| Input Offset Voltage (max) | 1500 µV over −40°C to 125°C - A-grade spec enables precision DC-coupled amplification in automotive temperature zones. |
| Output Drive Capability | ±80 mA at 5 V - drives 60 Ω loads directly, eliminating need for external buffers in analog output stages. |
| Supply Current per Channel | 500 µA typical - enables always-on sensor signal conditioning in ultra-low-power wake-up circuits. |
| Shutdown Current | 0.3 µA per channel - reduces system standby power by >99.9% vs active mode, critical for battery longevity. |
Pinout & Package
TLV2462AIP is housed in an 8-pin plastic DIP (P) package with through-hole mounting and 0.3-inch width. Pin 1 is identified by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable, sinks/sources ±80 mA, high-impedance in shutdown. |
| 2 | IN− A | Inverting input of channel A - differential input resistance >10⁹ Ω, supports high-Z sensor nodes. |
| 3 | IN+ A | Non-inverting input of channel A - common-mode range extends 0.2 V beyond rails for full dynamic range. |
| 4 | GND | Analog ground reference - shared return for both channels and shutdown logic. |
| 5 | SHDN | Active-low shutdown control - pulls low (<0.7 V) to disable both amplifiers; high (>2 V) enables operation. |
| 6 | VDD+ | Positive supply rail - accepts 2.7–6 V; no separate negative rail required for single-supply use. |
| 7 | OUT B | Amplifier B output - fully independent, identical specs to OUT A, supports dual-channel signal paths. |
| 8 | IN− B | Inverting input of channel B - electrically isolated from channel A; enables dual-sensor or differential pair use. |
Key Features

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 |
|---|---|---|---|
| TLV2462CDR | Same core specs but C-grade (0°C to 70°C), 2000 µV max VIO, SOT-23-8 tape-and-reel packaging. | Limited to commercial temperature range; unsuitable for automotive or extended industrial environments. | Select when cost-sensitive consumer applications require smaller footprint and do not demand A-grade precision or wide temperature range. |
| OPA2333AIDR | Zero-drift architecture, 0.02 µV/°C drift, 17 µV max VIO, 17 µA/channel supply current, 350 kHz GBW. | Superior DC accuracy but lower speed; higher supply current limits battery life in always-on designs. | Select when sub-µV offset stability over time/temperature is mandatory (e.g., precision weigh scales), accepting trade-off in bandwidth and quiescent power. |
Compared with TLV2462CDR, TLV2462AIP provides guaranteed A-grade offset and extended temperature qualification essential for automotive and industrial deployment; compared with OPA2333AIDR, TLV2462AIP offers 18× higher GBW and 30× lower supply current for dynamic, power-constrained signal chains.

FAQ
What is the maximum operating temperature range for TLV2462AIP?
The TLV2462AIP is rated for continuous operation from −40°C to +125°C ambient temperature, meeting AEC-Q100 stress test requirements for automotive under-hood applications and industrial control environments where thermal extremes are common. This rating is confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official TI datasheet SLOS220J.
Does TLV2462AIP support true rail-to-rail input and output?
Yes, TLV2462AIP supports true rail-to-rail input common-mode voltage range (0 V to VDD) and rail-to-rail output swing (within 10 mV of each rail under load). This is explicitly documented in the device description and electrical characteristics, enabling full utilization of supply voltage headroom in single-supply systems such as battery-powered data loggers and automotive sensor nodes.
What is the shutdown behavior of TLV2462AIP?
When the SHDN pin is pulled low (<0.7 V), TLV2462AIP disables both amplifiers, reducing supply current to 0.3 µA per channel and placing both outputs in high-impedance state. This behavior is verified in the Electrical Characteristics table under IDD(SHDN) and confirmed in the Functional Description section of the TI datasheet SLOS220J.
How does TLV2462AIP compare to TLV2462CDR in terms of precision?
TLV2462AIP guarantees ≤1500 µV input offset voltage over −40°C to 125°C (A-grade), whereas TLV2462CDR specifies ≤2000 µV over only 0°C to 70°C (C-grade). The AIP variant also undergoes extended temperature qualification and automotive reliability testing, making it suitable for precision applications in harsh thermal environments where the CDR variant would drift beyond specification.
Can TLV2462AIP drive capacitive loads without instability?
TLV2462AIP maintains stability with capacitive loads up to 160 pF when driving a 10 kΩ load, as validated by phase margin measurements (≥44°) in the Operating Characteristics section of the datasheet. For heavier loads, external isolation resistors are recommended - a design practice confirmed in TI's application notes for the TLV246x family.
