MAX41470GTC+

MAX41470GTC+ is a high-performance, low-power receiver with an SPI interface that is ideal for amplitude shift-keyed (ASK) and frequency shift-keyed (FSK) data. It is capable of both ASK and FSK reception and is also fully programmable through an SPI interface. The receiver has excellent RF sensitivity and allows input signals up to 0dBm of power at the RF input. With an integrated IF filter, a few external components, and low operating/power-down currents, this device receiver is ideal for cost- and power-sensitive applications. This device operates in the 1.8V to 3.6V supply voltage range and also features a power-saving, fully programmable, self-polling (duty cycling) mode with preamble detection and interrupt output to wake up an external microcontroller unit (MCU). It is used in applications such as home automation and security, building access control, garage door openers (GDO), remote keyless entry (RKE), tire pressure monitoring systems (TPMS), and restaurant pagers.
