LDO regulator has high PSRR for noise-sensitive applications
The AP7353 low dropout (LDO) regulator is designed to meet the need for voltage regulation in noise-sensitive, battery-operated devices such as wearables, portables, and connected sensors. It offers a high power supply rejection ratio (PSRR) in a small package, says Diodes.
Signal conditioner IC targets industry 4.0, medical and IoT sensor applications
The latest addition to the sensor signal conditioner (SSC) range is the ZSSC3240. According to Renesas, it delivers high accuracy, sensitivity, and flexibility for sensor applications such as resistive pressure sensors and medical infra red thermometers. It is also claimed to deliver best-in-class performance and speed with up to 24 bits analogue to digital conversion (ADC) resolution.
