The MAX323/MAX324/MAX325 are precision, dual, SPST analog switches. They are single-supply devices designed to operate from +2.7V to +16V. The MAX323 has two normally open (NO) switches, and the MAX324 has two normally closed (NC) switches. The MAX325 has one NO and one NC switch. Low power consumption (5µW) makes these parts ideal for battery-powered equipment. These switches offer low leakage currents (100pA max) and fast switching speeds (tON = 150ns max, tOFF = 100ns max).When powered from a 5V supply, the MAX323 series offers 2Ω max matching between channels, 60Ω max on-resistance, and 6Ω max RON flatness.These switches also offer 5pC max charge injection, and a minimum of 2000V ESD per Method 3015.7.For equivalent devices specified for dual-supply operation, see the MAX320/MAX321/MAX322 data sheet.

The MAX328/MA329 are monolithic CMOS analog multiplexers. The MAX328 is a single-ended, 1-of-8 device, and the MAX329 is a differential, 2-of-8 device.Designed to provide the lowest possible on- and off-leakages, these multiplexers switch signals from high source impedance, providing the mux operates into a high-input-impedance op amp or A/D converter. The MAX328/MAX329 are pin-for-pin replacements for the popular DG508/DG509 in these applications.Adding an external 40kΩ resistor to each input makes the MAX328/MAX329 an excellent fault-tolerant multiplexer. Low leakage (less than 1pA at +25°C) and 2.5kΩ on-resistance allow the circuit to sustain 110V AC faults indefinitely while maintaining an error of less than 40nV for normal signals (i.e., 1pA times 40kΩ).The MAX328/MAX329 work equally well with a single supply of 10V to 30V or dual supplies of ±5V to ±18V. They also perform well with unbalanced combinations of supply voltage, such as +12V and -5V or +5V and -15V. Low power dissipation (1.9mW with ±15V supplies) allows use in portable applications.

The DG202/DG212 are normally open, quad single-polesingle-throw (SPST) analog switches. TheseCMOS switches can be continuously operated withpower supplies ranging from ±4.5V to ±18V. Maximguarantees that these switches will not latch up if thepower supplies are disconnected with input signals stillconnected.The DG202/DG212 are similar to the DG201/DG211except for inverted control inputs. All devices haveguaranteed break-before-make switching, as well asessentially constant on-resistance over the analogsignal range. All switches conduct current in eitherdirection and add no offset to the output signal.Compared to the original manufacturer's products,Maxim's DG202/DG212 consume very little power,making them better suited for portable applications.Maxim has also eliminated the need for the third logicpower supply (VL) that is required for the operation ofthe original manufacturer's DG212 without sacrificingcompatibility.ApplicationsAnalog MultiplexersAutomatic Test EquipmentCommunication SystemsPBX, PABXProgrammable Gain AmplifiersSample/Holds
