The MAX4400–MAX4403 low-cost, general-purpose op amps offer rail-to-rail outputs, draw only 320µA of quiescent current, and operate from a single +2.5V to +5.5V supply. For additional power conservation, the MAX4401 offers a low-power shutdown mode that reduces supply current to 1µA (max) and puts the amplifier's output in a high-impedance state.

These devices deliver ±1.4mA of output current and are unity-gain stable with a 1MHz gain-bandwidth product driving capacitive loads up to 400pF. The MAX4400–MAX4403 are specified to +125°C, making them suitable for use in a variety of harsh environments, such as automotive applications. The MAX4400 single amplifier is available in ultra-small 5-pin SC70 and space-saving 5-pin SOT23 packages. The single MAX4401 includes the shutdown feature and is available in a 6-pin SC70. The MAX4402 is a dual amplifier available in 8-pin SOT23 and SO packages. The MAX4403 quad amplifier is packaged in a 14-pin TSSOP or SO.

The MLX90121 is an ISO compliant 13.56MHz RFID transceiver integrated circuit. The main features include user selectable modulation depth in write mode, whereas single sub-carrier, FSK and PSK modulations are recognized in the read mode. The receiver is based on a diode envelope detector, followed by an IF filter and amplifier.

The receiver is based on a diode envelope detector, followed by an IF filter and amplifier. A logarithmic amplifier is used for single subcarrier detection, ensuring fast and clean data recovery. The limiting output of the log amp is used for FSK and PSK recovery. The transmitter uses a built in open drain output transistor, which can provide up to 250 miliwatts of RF power to a 50 ohms load with a 5 volts power supply using the recommended matching network.
