CD4052BPW

CD4052BPW Description

The CD4052BPW from Texas Instruments is a high-performance dual 4-channel analog multiplexer/demultiplexer designed for precision signal routing in low-voltage and mixed-signal applications. Housed in a compact 16-pin TSSOP package, this IC features SP4T (Single Pole 4 Throw) switch circuits with two independent 4:1 multiplexers, enabling flexible signal management. It operates across a wide supply voltage range (3V–20V single or ±2.5V–9V dual), making it versatile for both single-supply and bipolar applications. With low on-state resistance (240Ω max) and minimal channel-to-channel matching (ΔRon = 5Ω), it ensures minimal signal distortion and high accuracy.

CD4052BPW Features

• Low Leakage Current: Max 100nA leakage ensures minimal power loss in off-state.
• High Bandwidth: -3dB bandwidth of 25MHz supports high-frequency signal switching.
• Low Capacitance: 0.2pF (CS(off)) / 18pF (CD(off)) reduces crosstalk and signal degradation.
• Dual-Supply Operation: Compatible with ±2.5V to ±9V for mixed-signal systems.
• Robust Construction: ROHS3 compliant and REACH unaffected, meeting environmental standards.
• Low Power Consumption: Ideal for battery-powered and portable devices.
• Surface-Mount Package: 16-TSSOP for space-constrained PCB designs.
