AS8500-ASOT

ADCs/DACs - Special Purpose Overview

The AS8500-ASOT is a low-power, high-precision data acquisition system designed for measuring small analog signals. It features a 16-bit resolution ADC with programmable gain amplifiers (PGA) offering gains of 6, 24, 50, and 100. The device operates on a single +5V supply with a typical power consumption of 15 mW. Key electrical characteristics include an input noise density of 35 nV/√Hz, an offset voltage better than 0.5 µV, and a maximum sampling frequency of 16 kHz. It integrates an internal temperature sensor, reference voltage, and programmable current sources.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'ASOT' against the manufacturer's official documentation to confirm package type and tape/reel specifications. Confirm availability status as older revisions may be discontinued or superseded by newer variants within the AS8500 family.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high accuracy in low-voltage signal conditioning. Ensure the external clock frequency does not exceed 8.192 MHz for standard operation, or 12 MHz within the 0 to 85°C range. Verify that the required gain settings align with the recommended temperature ranges for optimal linearity.

ADCs/DACs - Special Purpose Part Context

The AS8500 belongs to the universal multi-purpose data acquisition system family from ams-OSRAM (formerly Austria Microsystems). It is engineered specifically for front-end signal conditioning in harsh environments, particularly automotive battery management, where high precision and low power consumption are critical.

ADCs/DACs - Special Purpose Replacement Considerations

Check for updated revisions such as AS8500-ASOU or other suffixes within the same product line. Verify pin compatibility and register mapping if substituting with different packaging options.
