CD4052BM

CD4052BM Description

The CD4052BM from Texas Instruments is a dual 4:1 analog multiplexer/demultiplexer IC designed for high-performance signal routing in mixed-signal applications. Housed in a 16-SOIC package, it features SP4T (Single Pole 4 Throw) switch circuits with low on-state resistance (240Ω max) and minimal leakage current (100nA max). It supports dual (±2.5V to ±9V) or single (3V to 20V) supply voltages, making it versatile for both bipolar and unipolar systems. With a -3dB bandwidth of 25MHz and low channel capacitance (0.2pF off-state, 18pF on-state), it ensures minimal signal distortion in high-frequency applications.

CD4052BM Features

• Low On-Resistance: 240Ω max ensures minimal signal attenuation.
• Wide Voltage Range: Operates at ±2.5V to ±9V (dual) or 3V to 20V (single), accommodating diverse system requirements.
• High Bandwidth: 25MHz -3dB bandwidth for high-speed signal switching.
• Low Leakage & Capacitance: 100nA max leakage and 0.2pF/18pF capacitance reduce crosstalk and power loss.
