AD5700ACPZ-RL7

Overview

The AD5700ACPZ-RL7 is a low-power HART FSK half-duplex modem manufactured by Analog Devices. It integrates modulation, demodulation, filtering, and signal generation functions to comply with the HART physical layer requirements. The device operates on a supply voltage range of 1.71 V to 5.5 V for both VCC and IOVCC. In receive mode, it consumes a maximum of 115 µA. It supports clocking via an external crystal or CMOS source and features a buffered HART output with an 8 kV HBM ESD rating. The component is housed in a 4 mm × 4 mm LFCSP package and operates within a temperature range of −40°C to +125°C.
