F1956中文资料7-bit 0.25dB Glitch-Free™ Wideband Digital Step Attenuator数据手册Renesas规格书

描述 Description

The F1956 is part of a family of Glitch-Free™ DSAs which offers very high reliability due to its monolithic silicon die construction in a compact 5 x 5 mm 32-pin TQFN package.  It has very low insertion loss is with minimal distortion and is designed with a 50Ω input and output impedance. Additionally, the device is designed to have high accurate which improves SNR and/or ACLR by ensuring the system gain is achieved as close to targeted as possible.
