1pC Charge Injection, Low Leakage CMOS 4-Channel Multiplexer
The ADG604 is a CMOS analog multiplexer, comprising of four single channels. It operates from a dual supply of ±2.7 V to ±5.5 V, or from a single supply of +2.7 V to +5.5 V. The ADG604 switches one of four inputs to a common output, D, as determined by the 3-bit binary address lines, A0, A1 and EN. A Logic "0" on the EN pin disables the device.
The ADG604 offers ultra-low charge injection of 1pC and leakage currents of less than 250pA at 85ºC. It offers on-resistance of 85 Ω typ, which is matched to within 8 Ω between channels. The ADG604 also has low power dissipation yet gives high switching speeds. The ADG604 is available in a 14-lead TSSOP package.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
A 14-lead TSSOP device can be clamped or soldered to the center of the evaluation board. Each pin of the device that the eval board evaluates has a corresponding link from K1 to K14 that can be set to either VDD or GND. A wire screw terminal supplies VDD and GND. SMB connectors on the board allow additional external signals to be supplied to the device. In addition, there is space available at the top of the board for prototyping.
For full details, see the corresponding product data sheet, which must be used in conjunction with this user guide when using the evaluation board.
