Digital Attenuator, 15 dB, 4-Bit, TTL Driver, DC - 3.0 GHz AT65 - 0413
20 Icc Vcc = 4.5 to 5.5V Vctl = 0 to 0.8V, or Vcc -2.1V to Vcc — mA — — 4.0
Description M/A-COM’s AT65-0413 is a GaAs FET 4-bit digital attenuator with a 1.0 dB minimum step size and a 15 dB total attenuation range. This device is in a SOIC-16 plastic surface mount package. The AT65-0413 is ideally suited for use where accuracy, fast speed, very low power consumption and low costs are required. Typical applications include dynamic range setting in precision receiver circuits and other gain/leveling control circuits. Parameter Test Conditions Frequency Units Min. Typ. Max.
