The F1912 Glitch-Free™ Digital 步 Attenuator (DSA) offers very 高 reliability due to its monolithic silicon die construction in a compact 4mm x 4mm 20-pin package QFN package. The silicon design has very low insertion loss and low distortion (> +60dBm IP3I.) The device has pinpoint accuracy and settles to a final attenuation value within 400nsec. Most importantly, the F1912 includes Renesas' Glitch-Free technology which results in low overshoot and ringing during MSB transitions.
