MAX12900 Sensor Transmitter AFE

Analog Devices MAX12900 Sensor Transmitter Analog Front-End (AFE) is an ultra-low-power, highly integrated AFE for a 4mA to 20mA sensor transmitter. This AFE converts PWM data from a microcontroller into current over a 4mA to 20mA loop with two, three, or four-wire configurations. The Analog Devices MAX12900 integrates ten building blocks into a small package. This AFE is available in a 5mm x 5mm 32-pin TQFN package and operates over a temperature range of -40°C to 125°C.
