Аналоговые ключи MAX4638ESE+

Микросхема аналогового мультиплексора 8:1 , одиночный, 6Ом, 1.8В до 5.5В, NSOIC-16

The MAX4638ESE+ is a single 8 channel low voltage analogue multiplexer in 16 pin NSOIC package. This CMOS analogue multiplexer/demultiplexer operates from a single +1.8V to +5V supply or dual ±2.5V supplies. This device features 3.5ohm on-resistance (RON) when powered with a single +5V supply and have -75dB off-isolation and -85dB crosstalk from the output to each off channel. The switching times are 18ns tON and 7ns tOFF. It features a -3dB 85MHz bandwidth and has a 0.25nA leakage current at +25°C. A +1.8V to +5.5V operating range makes the device is ideal for battery-powered, portable instruments. All channels have break-before-make switching. This device feature bidirectional operation and can handle rail to rail analogue signals. All control inputs are TTL/CMOS logic compatible. Decoding is in standard BCD format and an enable input is provided to simplify cascading of devices.

• Maximum RON match between channels is 0.4ohm at 5V single supply
• Operating temperature range from -40°C to 85°C
• Maximum RON flatness over signal range is 1ohm at 5V single supply
• Low leakage current is 0.25nA at +25°C
• Rail to rail signal handling
• Charge injection is 13pC at 5V single supply
