The AD8029 (single), AD8030 (dual), and AD8040 (quad) are systems where component density requires lower power rail-to-rail input and output high speed amplifiers with a quiescent dissipation. The AD8040W is an automotive grade version, current of only 1.3 mA per amplifier. Despite their low power qualified for automotive applications. consumption

the amplifiers provide excel ent performance with The AD8029/AD8030 are the only low power, rail-to-rail input 125 MHz small signal bandwidth and 60 V/µs slew rate. Analog and output high speed amplifiers available in SOT23 and SC70 Devices, Inc., proprietary XFCB process enables high speed and micro packages. The amplifiers are rated over the extended high performance on low power. industrial temperature range, –40°C to +125°C. This family of amplifiers exhibits true single-supply operation
