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 prognostics 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 measurement, and access
the results - further extending the capabilities of an existing JTAG infrastructure.
The SCANSTA476 uses the VREF input as a reference. This
enables the SCANSTA476 to operate with a full-scale input
range of 0 to VDD, 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 -40°C to +85°C.
