The AT-110 has a faster switching speed than the AT-108 or AT-109. The AT-110 is ideally suited for use where linear attenuation fine tuning and very low power consumption are required. Typical applications include radio, cellular, GPS equipment and automatic gain/level control circuits. The AT-110 is fabricated with a monolithic GaAs MMIC using a mature 1-micron process. The process features full chip passivation for increased performance and reliability. 1 2 3 4 1. VCC = +5 VDC ± 0.5 VDC @ 300 µA maximum. 2. VC = 0 VDC to +5 VDC @ 6 mA maximum. 3.
