OPA858QDSGRQ1 Description

Short technical summary and product information.

The OPA858QDSGRQ1 is a high-performance operational amplifier designed specifically for demanding automotive and industrial applications. Featuring a 5.5 GHz gain bandwidth product and a 2000 V/µs slew rate, this decompensated amplifier maintains stability at gains of 7 V/V or higher. It utilizes FET/Cmos input architecture to deliver an ultra-low input bias current of 5 pA maximum and low input voltage noise of 2.5 nV/√Hz.

 

Operating within a supply voltage range of 3.3 V to 5.25 V, the device provides a typical quiescent current of 20.5 mA per channel and supports an output current of 80 mA. It includes a shutdown feature and is qualified to AEC-Q100 Grade 1 standards for operation across a temperature range of -40 °C to +125 °C. Packaged in an 8-pin WSON footprint measuring 2 mm by 2 mm, it offers a compact solution for space-constrained designs requiring high-speed signal conditioning.
