The AMC7891 is a highly-integrated, low-power, complete analog monitoring and control system in a very small package.
For monitoring functions, the AMC7891 has 8 uncommitted inputs multiplexed into a 10-bit SAR analog-to-digital converter (ADC) and an accurate on-chip temperature sensor. Control signals are generated through four, independent, 10-bit digital-to-analog converters (DACs). Additional digital signal monitoring and control is accomplished through twelve configurable GPIOs. An internal reference can be used to drive the ADC and DACs.
Communication to the device is performed through a versatile, four-wire serial interface compatible with industry-standard microprocessors and microcontrollers. The serial interface can operate at clock rates up to 30 MHz, allowing quick access to critical system data.
The device is characterized for operation over the temperature range of –40ºC to 105ºC and is available in a very small, 36-pin, 6-mm × 6-mm QFN package.
The AMC7891’s low power, small size and high-integration make it an ideal low-cost, bias control circuit for modern RF transistor modules such as the power amplifiers (PA) and low-noise amplifiers (LNA) found in RF communication systems. The AMC7891 feature set is similarly beneficial in general purpose monitor and control systems.
For applications that require a different channel count, additional features, or converter resolutions, Texas Instruments offers a complete family of Analog Monitor and Control (AMC) Products. See http://www.ti.com/amc.
