Integrated, Multichannel ADC and DAC for Analog Monitoring & Control - LMP92001
Datasheet
 

Description

The LMP92001 is a complete analog monitoring and control circuit which includes a sixteen channel 12-bit Analog to Digital Converter (ADC), twelve 12-bit Digital to Analog Converters (DACs), an internal reference, an internal temp sensor, an 8-bit GPIO port, and an I 2C-compatible interface.

The ADC can be used to monitor rail voltages, current sense amplifier outputs or sensors and includes a programmable window comparator function on six of its 16 channels to detect out-of range conditions.

The DACs can be used to control PA bias points, actuators, potentiometers, etc. When required, the outputs can be instantaneously driven to either supply rail using the output switches and the asynchronous DAC control inputs.

Both ADC and DACs can use either the internal 4.5V reference or an external reference independently.

The built-in temperature sensor is treated as the 17th analog sense input. In addition, the 8-bit GPIO port allows for the resources of the microcontroller to be further extended, providing even more flexibility.

The LMP92001 is available in a space saving 10mmx5.5mm LLP 54-pin package and is operational over the full − 40°C to 125°C temperature range.
