SCANSTA476
Eight Input IEEE 1149.1 Analog Voltage Monitor
General Description
The SCANSTA476 is a low power, Analog Voltage Monitor
used for sampling or monitoring up to 8 analog/mixed-signal
input channels. Analog Voltage Monitors are valuable during
product development, environmental test, production, and
field service for verifying and monitoring power supply and
reference voltages. In a supervisory role, the ’STA476 is
useful for card or system-level health monitoring and prog-
nostics applications.
Instead of requiring an external microcontroller with a GPIO
interface, the ’STA476 features a common IEEE 1149.1
(JTAG) interface to select the analog input, initiate a mea-
surement, and access the results - further extending the
capabilities of an existing JTAG infrastructure.
The SCANSTA476 uses the V
REF
input as a reference. This
enables the SCANSTA476 to operate with a full-scale input
range of 0 to V
DD
, which can range from +2.7V to +5.5V.
The SCANSTA476 is packaged in a 16-lead non-pullback
LLP package that provides an extremely small footprint for
applications where space is a critical consideration. This
product operates over the industrial temperature range of
40C to +85C.
