GENERAL DESCRIPTION
The ADM33xxE line of driver/receiver products is designed to
fully meet the EIA-232 standard while operating with a single
2.7 V to 3.6 V power supply. The devices feature an on-board
charge pump dc-to-dc converter, eliminating the need for dual
power supplies. This dc-to-dc converter contains a voltage
tripler and a voltage inverter that internally generates positive
and negative supplies from the input 3 V power supply. The dc-
to-dc converter operates in Green Idle mode, whereby the
charge pump oscillator is gated on and off to maintain the
output voltage at ±7.25 V under varying load conditions. This
minimizes the power consumption and makes these products
ideal for battery-powered portable devices.
The ADM33xxE devices are suitable for operation in harsh
electrical environments and contain ESD protection up to
±15 kV on their RS-232 lines (ADM3310E, ADM3311E,
ADM3312E, and ADM3315E). The ADM3307E contains ESD
protection up to ±15 kV on all I/O lines (CMOS, RS-232, EN,
and SD).
A shutdown facility that reduces the power consumption to 66 nW
is also provided. While in shutdown, one receiver remains active
(two receivers active with ADM3310E), thereby allowing monitor-
ing of peripheral devices. This feature allows the device to be shut
down until a peripheral device begins communication.
The active receiver can alert the processor, which can then take
the ADM33xxE device out of the shutdown mode.
The ADM3307E contains five drivers and three receivers and is
intended for mobile phone data lump cables and portable
computing applications.
The ADM3311E contains three drivers and five receivers and is
intended for serial port applications on notebook/laptop
computers.
The ADM3310E is a low current version of the ADM3311E.
This device also allows two receivers to be active in shutdown
mode.
The ADM3312E contains three drivers and three receivers and
is intended for serial port applications, PDAs, mobile phone
data lump cables, and other hand-held devices.
The ADM3315E is a low current version of the ADM3312E,
with a 22 kΩ receiver input resistance that reduces the drive
requirements of the DTE. Its main applications are PDAs,
palmtop computers, and mobile phone data lump cables.
The ADM33xxE devices are fabricated using CMOS technology
for minimal power consumption. All parts feature a high level
of overvoltage protection and latch-up immunity.
All ADM33xxE devices are available in a 32-lead 5 mm × 5 mm
LFCSP_WQ and in a TSSOP (ADM3307E, ADM3310E, and
ADM3311E in a 28-lead TSSOP; ADM3312E and ADM3315E
in a 24-lead TSSOP). The ADM3311E also comes in a 28-lead
SSOP.
The ADM33xxE devices are ruggedized RS-232 line
drivers/receivers that operate from a single supply of 2.7 V to
3.6 V. Step-up voltage converters coupled with level shifting
transmitters and receivers allow RS-232 levels to be developed
while operating from a single supply. Features include low
power consumption, Green Idle operation, high transmission
rates, and compatibility with the EU directive on electromag-
netic compatibility. This EM compatibility directive includes
protection against radiated and conducted interference,
including high levels of electrostatic discharge.
All RS-232 (and CMOS, SD, and EN for ADM3307E) inputs and
outputs are protected against electrostatic discharges (up to
±15 kV). This ensures compliance with IEC 1000-4-2
requirements.
These devices are ideally suited for operation in electrically
harsh environments or where RS-232 cables are frequently
being plugged/unplugged. They are also immune to high RF
field strengths without special shielding precautions.
Emissions are also controlled to within very strict limits. CMOS
technology is used to keep the power dissipation to an absolute
minimum, allowing maximum battery life in portable
applications.
