OPA300AIDBVT

Instrumentation, Op Amps, Buffer Amps Overview

The OPA300AIDBVT is a single-channel, high-speed, low-noise CMOS operational amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and features rail-to-rail input and output capabilities. Key electrical parameters include a gain-bandwidth product of 150 MHz, a slew rate of 80 V/µs, an input offset voltage of 5 mV, and an input bias current of 5 pA. The device draws 9.5 mA of operating current per channel and provides 70 mA of output current. It exhibits an input voltage noise density of 3 nV/√Hz and an input current noise density of 1.5 fA/√Hz. Common-mode rejection ratio is specified at 80 dB. The component is housed in a SOT-23-6 package and supports operation across a temperature range of -40°C to +125°C.
