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
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 WSON 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.
