3 Description
The AMC67048 is a highly integrated analog systemguard
designed for high-density, general-purpose
monitor-control systems, telemetry, and redundancy
safety. The AMC67048 has a 12-bit, 250kSPS analogto-
digital converter (ADC) with up to 40 channels. The
ADC has a programmable output range from either
0V to 2.5V or 0V to 5V. The device incorporates
eight, 12-bit digital-to-analog converters (DACs) with
a high-current drive capable of sourcing and sinking
up to 100mA. In addition, the device contains FLEXIO
pins that can either be device inputs or outputs,
and are part of the device guard logic. The guard
logic is designed to simplify monitoring through
multiple alarms, out-of-bound ADC monitoring, and
sequencing. The FLEXIO and DAC pins can be used
as additional ADC channels.
Communication to the device is done through an
autodetected, 4-wire SPI-compatible or 2-wire I2C
interface.
The AMC67048 high channel density, guard features,
wide operating temperature range, and guard logic
make this device an excellent choice for system
monitoring and redundancy safety monitoring in
applications such as servers and avionics telemetry.
This device is designed to work independently
through the integrated alarm detection or work with
an MCU to provide all-in-one system monitoring.
