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.

Key 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.

SCANSTA476 Eight Input IEEE 1149.1 Analog Voltage Monitor April 2005 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 prognostics applications. Instead of requiring an external microcontroller with a GPIO interface, the ’STA476 features a common IEEE 1149.
