MAX4589EWP集成电路（IC）的模拟开关-特殊用途规格书PDF中文资料

General Description

The MAX4589 low-voltage, dual 2-channel multiplexer is designed for RF and video signal processing at frequencies up to 200MHz in 50Ω and 75Ω systems. On-chip functions are controlled through either a parallel interface or an SPI™/QSPI™/MICROWIRE™ serial interface.

Each channel of the MAX4589 is designed using a “T” switch configuration, ensuring excellent high-frequency off-isolation. The MAX4589 has low on-resistance of 60Ω max, with an on-resistance match across all chan nels of 4Ωmax. Additionally, on-resistance is flat across the specified signal range (2Ωmax). The off leakage current is under 1nA at TA= +25°C, and less

than 10nA at TA= +85°C.
