Packaged in industry standard SIP-7 or SIP-8 formats
the units occupy very little PCB. The IMM01 uses a SIP7
footprint and measures 19.50 x 10.60 x 9.20 mm. The
SIP8 2 Watt IMM02 is 21.85 x 10.60 x 9.20 mm. Capable
of operating in most environments over the extended
operating temperature range of – 20 to + 100 degrees C,
the convection cooled units can deliver full power up to +
60 degrees C.
A remote On/Off input pin allows external control of the
converter operation from a host application such as to
sequence startup.
The IMM series is available from Farnell, element14, Digi-
Key, approved regional distributors, or direct from XP Power
and come with a 3 year warranty.
TI introduces the industry’s highest
performing reinforced isolated amplifier
Texas Instruments (TI) (NYSE: TXN) today introduced a
reinforced isolated amplifier with the highest reliability, lowest
power consumption, highest DC accuracy and improved
overall efficiency compared to competitive devices. The
AMC1301 is the newest addition to TI’s reinforced isolation
portfolio, which features the industry’s highest working
voltage specifications. With the lowest offset drift of 3 uV/C
over the widest temperature range, -40C to 125C, the
AMC1301 delivers the most accurate solution for shunt-
based current sensing in high-voltage equipment, such as
industrial motor drives, solar inverters, battery management
systems and uninterruptible power supplies. For more

Key features and benefits
Highest reliability and longer lifespan: The AMC1301
is the industry’s first isolated amplifier with a working
breakdown voltage of 1,000 Vrms for a minimum insulation
barrier lifetime of 64 years, which exceeds VDE0884-10
requirements. Like all of the isolated devices in TI’s portfolio,
the AMC1301 has no relevant lifetime degradation, unlike
optical components.
Lowest power consumption: At 55 percent less high-side
supply current and 45 percent less low-side supply current
than competitive devices, the isolated amplifier improves
power efficiency, simplifies power supply design and
reduces thermal drift issues for a more efficient system
design and improved performance.
Highest DC accuracy: With the lowest offset error maximum
of 200 uV, the lowest offset drift and the best linearity of 0.03
percent, the AMC1301 enables engineers to design the
most accurate system using an isolated amplifier over the
widest temperature range, without having to compensate
for DC and temperature drift errors.
Tools and support to ease design
TI offers the following tools to help designers quickly select,
evaluate and design with the new AMC1301 reinforced
isolated amplifier:
ATINA-TI™ SPICE model and TINA-TI reference design are
available for the AMC1301 to help designers verify board-
level signal-integrity requirements.
The AMC1301EVM evaluation module (EVM) is priced
at US$49 and enables engineers to quickly and easily
evaluate device features and performance to help speed
time to market.
A TI Designs reference design is available, which allows
designers to use the AMC1301 to jump-start design of a
cost-efficient reinforced isolated power stage in three-
phase inverters, with the benefits of reduced power supply
requirements and protection against DC bus under- and
over-voltage.
Technical support for the AMC1301 is available in the
TI E2E™ Community Precision Amplifier forum, where
engineers can search for solutions, get help, share
knowledge and solve problems with fellow engineers and
TI experts.
Package, availability and pricing
The AMC1301 is available today in a 5.85-mm-by-7.5-mm
small outline integrated circuit (SOIC) package for US$2.90
in 1,000-unit quantities.
Optimize reinforced isolation design
For motor control or solar inverters, which require a signal
and power across the isolation barrier, and a small form
factor, the AMC1301 can be paired with TI’s SN6505B, the
industry’s smallest transformer driver, to simplify isolated
system design.
When used in conjunction with an isolated power supply,
such as the LM5017 100-V dual-output DC/DC Fly-Buck™
