MAX4526CSA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4526CSA is a phase-reversal analog switch from the MAX4526/MAX4527 series, optimized for high-speed applications. It operates on single supplies of +4.5V to +36V or dual supplies of ±4.5V to ±18V. The device features two SPDT switches with a maximum on-resistance of 175Ω and a maximum match of 8Ω. Transition time is typically 95ns at ±15V. Leakage current is 0.5nA at +25°C and 10nA at +85°C. Charge injection is 10pC max. It uses an 8-pin SO package and supports a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CSA indicates the commercial temperature grade (0°C to +70°C) and SOIC-8 package format. Confirm RoHS compliance status as the datasheet does not explicitly state it for this part number. Check for obsolescence notices from Analog Devices regarding this specific component variant before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4526 over the MAX4527 when higher speed and faster transition times are required for chopper amplifier applications. Ensure the supply voltage range matches the system requirements, as the device supports both single and dual supply configurations. Verify that the 175Ω on-resistance meets the signal integrity needs of the application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4526CSA belongs to the MAX4526/MAX4527 family of CMOS analog switches designed for phase-reversal functions. This family provides a compact solution for balancing signals in bridge configurations. The MAX4526 variant specifically targets high-frequency performance compared to the low-power MAX4527 counterpart.
