GENERAL DESCRIPTION
The ADG736L is a monolithic device comprising two independently selectable CMOS single pole, double throw (SPDT) switches. The switches are designed using a submicron process that provides low power dissipation, yet gives high switching speed, low on resistance, low leakage currents, and wide input signal bandwidth. The on resistance profile is very flat over the full analog signal range. This ensures excellent linearity and low distortion when switching audio signals. Fast switching speed also makes the part suitable for video signal switching. The ADG736L operates from a single 1.8 V to 5.5 V supply, making it ideally suited to portable and battery-powered instruments. Each switch conducts equally well in both directions when on; each has an input signal range that extends to the power supplies. The ADG736L exhibits break-before-make switching action. The ADG736L is available in a 10-lead MSOP.

ADG736L TERMINOLOGY
RON Ohmic resistance between D and S. RON On resistance match between any two channels, such as RON maximum - RON minimum. RFLAT (ON) Flatness is defined as the difference between the maximum and minimum value of on resistance as measured over the specified analog signal range. IS (OFF) Source leakage current with the switch off. ID, IS (ON) Channel leakage current with the switch on. VD (VS) Analog voltage on Terminal D and Terminal S. CS (OFF) Off switch source capacitance. CD, CS (ON) On switch capacitance. tON Delay between applying the digital control input and the output switching on (see Figure 13). tOFF Delay between applying the digital control input and the output switching off. tD Off time or on time measured between the 90% points of both switches, when switching from one address state to another (see Figure 14). Crosstalk A measure of unwanted signal that is coupled through from one channel to another as a result of parasitic capacitance. Off Isolation A measure of unwanted signal coupling through an off switch. Bandwidth The frequency at which the output is attenuated by -3 dB. On Response The frequency response of the on switch. On Loss The voltage drop across the on switch, seen on the On Response vs. Frequency plot (see Figure 7) as how many decibels the signal is away from 0 dB at very low frequencies.
