6 Specifications

6.1 Absolute Maximum Ratings

over operating junction temperature range (unless otherwise noted)(1)
MINMAXUNIT
Supply voltage, ([V+] – [V–])06V
Signal input pinsVoltage(2)Common-mode(V–) – 0.5(V+) + 0.5V
Differential(5)(V+) – (V–) + 0.2V
Current(2)–1010mA
Output short-circuit(3)(4)Continuous
Operating, TA–55125°C
Operating junction temperature, TJ150°C
Storage temperature, Tstg–65150°C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Input pins are diode-clamped to the power-supply rails. Input signals that may swing more than 0.5 V beyond the supply rails must be current limited to 10 mA or less.
(3) Short-circuit to ground, one amplifier per package.
(4) Long term continuous current limit is determined by electromigration limits
(5) Differential input voltages greater than 0.5 V applied continuously can result in a shift to the input offset voltage above the maximum specification of this parameter. The magnitude of this effect increases as the ambient operating temperature rises.

6.2 ESD Ratings

(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

7 Detailed Description

7.1 Overview

The LM290xLV-Q1 family of low-power op amps is intended for cost-optimized systems. These devices operate from 2.7 V to 5.5 V, are unity-gain stable, and are designed for a wide range of general-purpose automotive applications. The input common-mode voltage range includes the negative rail and allows the LM290xLV-Q1 family to be used in many single-supply applications.
