MAX4701EUE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4701EUE+T is a low-voltage, single-supply CMOS analog switch featuring two independent double-pole/double-throw (DPDT) channels. It operates from a +1.8V to +5.5V power supply and provides rail-to-rail signal handling with a maximum on-resistance of 75Ω at +3V and 40Ω at +5V. The device guarantees a channel-to-channel matching of 4Ω and flatness of 12Ω over the signal range. Switching speeds are fast, with turn-on time of 35ns and turn-off time of 20ns at +3V. It exhibits low leakage currents of 1nA max at +85°C, an off-isolation of -76dB at 1MHz, and crosstalk of -79dB at 1MHz. The component is housed in a 16-lead TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and RoHS compliance status. Ensure that the logic supply requirements align with the system design, as digital input thresholds vary based on the operating voltage. Cross-reference the datasheet revision history to confirm any updates to absolute maximum ratings or electrical characteristics prior to final procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual DPDT switching is required within a low-voltage single-supply environment. Verify that the system's logic levels are compatible with the specified VIH and VIL thresholds at the intended operating voltage. Consider the thermal dissipation capabilities of the TSSOP package if high continuous current loads are expected. Confirm that the 75Ω on-resistance meets the signal integrity requirements of the application.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4701 belongs to the MAX4699/MAX4701/MAX4702 family of low-voltage analog switches manufactured by Analog Devices / Maxim Integrated. While the MAX4701 offers a dual DPDT configuration, the MAX4702 provides a quad SPDT arrangement with a dedicated logic supply pin. Both share similar electrical characteristics but differ in control input architecture and pinout configurations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4699ETE+ serves as a physical replacement option offering identical electrical specifications in a 16-lead TQFN-EP package. Designers must account for the footprint difference between TSSOP and TQFN when substituting components. The MAX4702EUE+ shares the same TSSOP package but features a different internal topology and control scheme.
