ADA4891-1

The ADA4891-1 (single)is CMOS, high speed amplifiers that offer high performance at a low cost. The amplifiers feature true single-supply capability, with an input voltage range that extends 300 mV below the negative rail. In spite of their low cost, the ADA4891 family provides high performance and versatility. The rail-to-rail output stage enables the output to swing to within 50 mV of each rail, enabling maximum dynamic range. The ADA4891 family of amplifiers is ideal for imaging applications, such as consumer video, CCD buffers, and contact image sensor and buffers. Low distortion and fast settling time also make them ideal for active filter applications. The ADA4891-1 is available in a wide variety of packages. The ADA4891-1 is available in 8-lead SOIC and 5-lead SOT-23 packages. The amplifiers are specified to operate over the extended temperature range of -40°C to +125°C.

The features of ADA4891-1 can be summarized as (1)high speed and fast settling -3 dB bandwidth: 220 MHz (G = +1)/ slew rate: 170 V/s/ settling time to 0.1%: 28 ns; (2)video specifications (G = +2, R L = 150 )0.1 dB gain flatness: 25 MHz/ Differential gain error: 0.05% / Differential phase error: 0.25°; (3)single-supply operation wide supply range: 2.7 V to 5.5 V/ output swings to within 50 mV of supply rails; (4)low distortion: 79 dBc SFDR at 1 MHz; (5)linear output current: 125 mA at -40 dBc; (6)low power: 4.4 mA per amplifier.

The absolute maximum ratings of ADA4891-1 are (1)supply voltage: 6 V; (2)input voltage(common mode): -V S - 0.5 V to +V S; (3)differential input voltage: ±V S; (4)storage temperature range: -65°C to +125°C; (5)operating temperature range: -40°C to +125°C; (6)lead temperature (Soldering, 10 sec): 300°C.
