ADC0820BCM

Analog To Digital Converters (ADC) Overview

The ADC0820BCM is an 8-bit, 500 kSPS analog-to-digital converter manufactured by Analog Devices Inc. (formerly Maxim Integrated). It features a single-supply operation at +5V and includes a built-in track-and-hold circuit to maintain signal integrity during conversion. The device utilizes a standard serial interface compatible with microprocessors, requiring only three control lines for data transfer. Key electrical specifications include a full-scale input range of 0 to VCC, a typical conversion time of 2 microseconds, and a power-down mode that reduces current consumption significantly when not in use.

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer marking on the component body to confirm it originates from Analog Devices or Maxim Integrated, as legacy branding may vary. Ensure the suffix 'BCM' corresponds to the correct package type and temperature grade specified in the official datasheet before ordering. Cross-reference the part number with current Analog Devices catalogs to confirm availability and any potential obsolescence status.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and moderate speed up to 500 kSPS are sufficient for the application. It is suitable for designs requiring low power consumption due to its single-supply architecture and power-down capability. Consider the serial interface requirements to ensure compatibility with the host microcontroller's available GPIO pins and clock speeds.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC082x family of high-speed, low-power A/D converters. The ADC0820 variant specifically offers 8-bit resolution, distinguishing it from higher-resolution counterparts like the ADC0830 or ADC0840. The BCM suffix typically denotes a specific package configuration and commercial temperature range defined by the manufacturer's packaging standards.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include other ADC082x variants if resolution differences are acceptable. Verify that any substitute maintains the 500 kSPS speed and serial interface timing characteristics. Check for updated revisions from Analog Devices that may offer improved performance or availability while maintaining functional equivalence.
