GENERAL DESCRIPTION
The ADG1401/ADG1402 contain a single-pole/single-throw
(SPST) switch. Figure 1 shows that with a logic input of 1, the
switch of the ADG1401 is closed and that of the ADG1402 is
open. 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 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.
The iCMOS® (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 a reduced package size.

Over voltages at IN, S, or D are clamped by internal diodes. Current should
be limited to the maximum ratings given.
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.

TERMINOLOGY
IDD
The positive supply current.
CD, CS (On)
ISS
The negative supply current.
CIN
The digital input capacitance.
VD (VS)
The analog voltage on Terminal D and Terminal S.
tON
Delay time between the 50% and 90% points of the digital input
and switch on condition. See Figure 23.
The on switch capacitance, measured with reference to ground.
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.
tOFF
Delay time between the 50% and 90% points of the digital input
and switch off condition. See Figure 23.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during switching. See Figure 24.
Off Isolation
A measure of unwanted signal coupling through an off switch.
See Figure 25.
ID (Off)
The drain leakage current with the switch off.
ID, IS (On)
The channel leakage current with the switch on.
Bandwidth
The frequency at which the output is attenuated by 3 dB.
See Figure 26.
VINL
The maximum input voltage for Logic 0.
On Response
The frequency response of the on switch.
VINH
The minimum input voltage for Logic 1.
Insertion Loss
The loss due to the on resistance of the switch. See Figure 26.
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.
THD + N
The ratio of the harmonic amplitude plus noise of the signal to
the fundamental. See Figure 27.
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 the
signal on the output to the amplitude of the modulation is the
ACPSRR. See Figure 19.
