Specifications

Description M/A-COM's AT65-0263 is a GaAs FET 5-bit digital attenuator with integral TTL driver. Step size is 1.0 dB providing 31 dB total attenuation range. This device is in a SOW-16 plastic surface mount package. The AT65-0263 is ideally suited for use where accuracy, fast speed, very low power consumption and low costs are required. Package outline conforms to JEDEC standard MS-013AA. 1.Decoupling capacitors (.01 μF) are required on power supply lines.
