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 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.
