Maxim MAX7033 315MHz/433MHz ASK Superheterodyne Receiver with AGC Lock Datasheet
The MAX7033 integrates a low‑noise amplifier, differential image‑rejection mixer, on‑chip PLL/VCO, IF limiting amplifier with RSSI, and baseband data‑recovery circuitry. It operates from a single +3.3 V or +5.0 V supply and includes a one‑step automatic gain control that reduces LNA gain by 35 dB when the RF input exceeds -62 dBm, with an external hold feature.
Typical applications include home automation, remote controls, automotive keyless entry, security systems, and garage‑door openers. The device is offered in 28‑pin TSSOP and 32‑pin TQFN packages and is rated for -40 °C to +105 °C operation.
