ADG1422 Functional Block Diagram GENERAL DESCRIPTION The ADG1421/ADG1422/ADG1423 contain two independent single-pole/single-throw (SPST) switches. The ADG1421 and ADG1422 differ only in that the digital control logic is inverted. The ADG1421 switches are turned on with Logic 1 on the appropriate control input, and Logic 0 is required for the ADG1422. The ADG1423 has one switch with digital control logic similar to that of the ADG1421; the logic is inverted on the other switch. The ADG1423 exhibits break-before-make switching action for use in multiplexer applications. Each switch conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. The iCMOS(R) (industrial CMOS) modular manufacturing process combines high voltage, complementary metal-oxide semiconductor (CMOS) and bipolar technologies. It enables the development of a wide range of high performance analog ICs capable of 33 V operation in a footprint that no other generation of high voltage parts has achieved. Unlike analog ICs using conventional CMOS processes, iCMOS components can tolerate high supply voltages while providing increased performance, dramatically lower power consumption, and reduced package size. ADG1423 S1 IN1 D1 D2 IN2 S2 SWITCHES SHOWN FOR A LOGIC 0 INPUT Figure 3. ADG1423 Functional Block Diagram The on resistance profile is very flat over the full analog input range ensuring excellent linearity and low distortion when switching audio signals. The iCMOS construction ensures ultralow power dissipation, making the part ideally suited for portable and battery-powered instruments.

VD (VS) The analog voltage on Terminal D and Terminal S. RON The ohmic resistance between Terminal D and Terminal S. 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) The source leakage current with the switch off. ID (Off) The drain leakage current with the switch off. ID, IS (On) The channel leakage current with the switch on. VINL The maximum input voltage for Logic 0. VINH The minimum input voltage for Logic 1. IINL (IINH) The input current of the digital input. CS (Off) The off switch source capacitance, measured with reference to ground. CD (Off) The off switch drain capacitance, measured with reference to ground. CD, CS (On) The on switch capacitance, measured with reference to ground. CIN The digital input capacitance. tON (EN) Delay time between the 50% and 90% points of the digital input and switch on condition. See Figure 26. tOFF (EN) Delay time between the 50% and 90% points of the digital input and switch off condition. See Figure 26. tTRANSITION Delay time between the 50% and 90% points of the digital inputs and the switch on condition when switching from one address state to another. TBBM Off time measured between the 80% point of both switches when switching from one address state to another. See Figure 27. Charge Injection A measure of the glitch impulse transferred from the digital input to the analog output during switching. See Figure 28. Off Isolation A measure of unwanted signal coupling through an off switch. See Figure 29. Crosstalk A measure of unwanted signal that is coupled through from one channel to another as a result of parasitic capacitance. See Figure 30. Bandwidth The frequency at which the output is attenuated by 3 dB. See Figure 31. On Response The frequency response of the on switch. Insertion Loss The loss due to the on resistance of the switch. See Figure 31. THD + N The ratio of the harmonic amplitude plus noise of the signal to the fundamental. See Figure 32. AC Power Supply Rejection Ratio (ACPSRR) ACPSRR measures the ability of a part to avoid coupling noise and spurious signals that appear on the supply voltage pin to the output of the switch. The dc voltage on the device is modulated by a sine wave of 0.62 V p-p. The ratio of the amplitude of signal on the output to the amplitude of the modulation is the ACPSRR. See Figure 22.
