The ams-OSRAM USA INC. AS1545 is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC). This component offers a sampling rate of 1 MSPS and supports up to 12 single-ended or 6 differential/pseudo-differential inputs through its multiplexer. The AS1545 features two SAR ADCs, enabling simultaneous sampling capabilities. Data is transferred via an SPI interface. It supports both external and internal voltage references and operates across an analog and digital supply voltage range of 2.7V to 5.25V. The device's 32-TQFN (5x5) package with an exposed pad is suitable for surface mount applications. This ADC is commonly employed in industrial automation, medical instrumentation, and consumer electronics.
