GENERAL DESCRIPTION
The ADG795A/ADG795G are monolithic CMOS devices
comprising five 2:1 multiplexers/demultiplexers controllable via
a standard I2C serial interface. The CMOS process provides
ultralow power dissipation, yet gives high switching speed and
low on resistance.
that allow up to eight devices on the same bus. This allows the
user to expand the capability of the device by increasing the size
of the switching array.
The ADG795A/ADG795G operate from a single 3 V or 5 V
supply voltage and are available in a compact 4 mm × 4 mm
body, 24-lead, lead-free package (LFCSP).
The on-resistance profile is very flat over the full analog input
range and wide bandwidth ensures excellent linearity and low
distortion. These features, combined with a wide input signal
range make the ADG795A/ADG795G the ideal switching
solution for a wide range of TV applications including S-video,
RGB and YPbPr video switches.
PRODUCT HIGHLIGHTS
1. Wide bandwidth: 325 MHz.
2. Ultralow power dissipation.
3. Extended input signal range.
4. Integrated I2C serial interface.
The switches conduct equally well in both directions when on.
In the off condition, signal levels up to the supplies are blocked.
The ADG795A/ADG795G switches exhibit break-before-make
switching action. The ADG795G has one general-purpose logic
output pins controlled by the I2C interface that can also be used
to control other non-I2C-compatible devices such as video filters.
The integrated I2C interface provides a large degree of flexibility
in the system design. It has three configurable I2C address pins
5. Compact 4 mm × 4 mm, 24-lead, lead-free LFCSP.
6. ESD protection tested as per ESD Association standards:
4 kV HBM (ANSI/ESD STM5.1-2001)
200 V MM (ANSI/ESD STM5.2-1999)
1 kV FICDM (ANSI/ESDSTM5.3.1-1999)
