3 Description

The OPAx992-Q1 family (OPA992-Q1, OPA2992-Q1, and OPA4992-Q1) is a family of high voltage (40V) general purpose operational amplifiers. These devices offer excellent DC precision and AC performance, including rail-to-rail input or output, low offset (±210µV, typical), low offset drift (±0.25µV/°C, typical) and low noise (7nV/√Hz at 1kHz, 4.4nV/√Hz at 10kHz).

Features such as differential and common-mode input voltage ranges to the supply rails, high short-circuit current (±65mA), and high slew rate (32V/µs) make the OPAx992-Q1 a flexible, robust, and high-performance op amp for high-voltage automotive applications.

The OPAx992-Q1 family of op amps is available in standard packages (such as SOIC, TSSOP, VSSOP, SOT-23, and SC70), and is specified from –40°C to 125°C.

5 Specifications

5.1 Absolute Maximum Ratings

over operating ambient temperature range (unless otherwise noted)⁽¹⁾

		MIN	MAX	UNIT
Supply voltage, V_S = (V+) – (V–)		0	42	V
Signal input pins	Common-mode voltage⁽³⁾	(V–) – 0.5	(V+) + 0.5	V
	Differential voltage⁽³⁾		V_S + 0.2	V
	Current⁽³⁾	–10	10	mA
Output short-circuit⁽²⁾		Continuous
Operating ambient temperature, T_A		–55	150	°C
Junction temperature, T_J			150	°C
Storage temperature, T_stg		–65	150	°C

(1) Operating the device beyond the ratings listed under Absolute Maximum Ratings will cause permanent damage to the device. These are stress ratings only, based on process and design limitations, and this device has not been designed to function outside the conditions indicated under Recommended Operating Conditions. Exposure to any condition outside Recommended Operating Conditions for extended periods, including absolute-maximum-rated conditions, may affect device reliability and performance.

(2) Short-circuit to ground, one amplifier per package. Extended short-circuit current, especially with higher supply voltage, can cause excessive heating and eventual destruction.

(3) Input pins are diode-clamped to the power-supply rails. Input signals that may swing more than 0.5V beyond the supply rails must be current limited to 10mA or less.
