GENERAL DESCRIPTION
The ADG841 and ADG842 are low voltage CMOS devices containing a single-pole, single-throw (SPST) switch. The ADG841 is closed for a Logic 1 input and the ADG842 is open for a Logic 1 input. The devices offer ultralow on resistance of less than 0.48 over the full temperature range. The ADG841/ ADG842 are fully specified for 3.3 V, 2.5 V, and 1.8 V supply operation. Each switch conducts equally well in both directions when on, and has an input signal range that extends to the supplies. The ADG841/ADG842 exhibit break-before-make switching action. The ADG841/ADG842 are available in a 6-lead SC70 package.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Only one absolute maximum rating may be applied at any one time.
Overvoltages at S or D are clamped by internal diodes. Current should be limited to the maximum ratings given.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

IINL (IINH) Input current of the digital input. CS (OFF) Off switch source capacitance. Measured with reference to ground. CD (OFF) Off switch drain capacitance. Measured with reference to ground. CD, CS (ON) On switch capacitance. Measured with reference to ground. CIN Digital input capacitance. tON Delay time between the 50% and the 90% points of the digital input and switch on condition. tOFF Delay time between the 50% and the 90% points of the digital input and switch off condition. Charge Injection A measure of the glitch impulse transferred from the digital input to the analog output during on-off switching. Off Isolation A measure of unwanted signal coupling through an off switch. -3 dB Bandwidth The frequency at which the output is attenuated by 3 dB. On Response The frequency response of the on switch. Insertion Loss The loss due to the on resistance of the switch. THD + N The ratio of the harmonics amplitude plus noise of a signal to the fundamental. PSRR Power Supply Rejection Ratio. This is a measure of the coupling of unwanted ac signals on the power supply to the switch output when the supply is not decoupled.
