AS1530

Analog To Digital Converters (ADC) Overview

The AS1530 is a 12-bit, 8-channel analog-to-digital converter (ADC) designed for single-supply operation. It supports sampling rates up to 400ksps with a typical supply current of 2.8mA at full speed. The device operates from a +4.5V to +5.5V supply and features an internal 2.5V reference. Data access is handled via a high-speed, 4-wire serial interface compatible with SPI, QSPI, and Microwire protocols. The component is housed in a 20-pin TSSOP package.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with 8 software-configurable analog input channels

• Pen-digitizers
• Process control systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the voltage supply requirements align with the +4.5V to +5.5V range specified for the AS1530 variant. Check for any environmental or reliability certifications required for the intended deployment environment.

Analog To Digital Converters (ADC) Selection Notes

Select the AS1530 when a 12-bit resolution and 400ksps throughput are required within a single-supply architecture. Ensure the system voltage falls within the +4.5V to +5.5V range. Consider the AS1531 if a lower supply voltage (+2.7V to +3.6V) and slower 300ksps rate are acceptable. Verify that the 20-pin TSSOP package fits the board layout constraints.

Analog To Digital Converters (ADC) Part Context

The AS1530 is part of a family of low-power, successive-approximation register (SAR) ADCs manufactured by AMS. It shares architectural similarities with the AS1531 but differs in supply voltage and maximum sampling speed. The device utilizes a high-bandwidth track/hold circuitry and multi-mode operation to optimize power consumption during varying throughput rates.

Analog To Digital Converters (ADC) Replacement Considerations

The AS1531 is a related component within the same product family. It offers identical 12-bit resolution and channel count but operates at a lower supply voltage (+2.7V to +3.6V) and reduced sampling rate (300ksps). Direct pin-for-pin replacement requires verifying that the system supply voltage meets the AS1531's minimum requirement.
