AS1530-T

Analog To Digital Converters (ADC) Overview

The AS1530-T is an 8-channel, 12-bit analog-to-digital converter utilizing successive-approximation register (SAR) architecture. Designed for single-supply operation, it supports a voltage range of +4.5V to +5.5V and achieves a sampling rate of 400ksps with a typical supply current of 2.8mA. The device integrates a 2.5V internal reference and offers software-configurable input modes, including single-ended, pseudo-differential, and fully differential configurations. Data access is facilitated via a high-speed, 4-wire serial interface compatible with SPI, QSPI, and Microwire protocols. It is housed in a compact 20-pin TSSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'T' against the manufacturer's official documentation to confirm packaging details, such as tape-and-reel configuration or moisture sensitivity level. Ensure the component source matches the Austriamicrosystems (ams-OSRAM) specification sheet revision 1.02 to guarantee electrical parameter compliance.

Analog To Digital Converters (ADC) Selection Notes

Select the AS1530-T when a 12-bit SAR ADC with 400ksps throughput is required within a +4.5V to +5.5V supply domain. Consider this part for space-constrained designs due to its 20-pin TSSOP footprint. Evaluate power requirements carefully; while normal operation draws 2.8mA, reduced-power and full power-down modes are available for lower throughput applications.

Analog To Digital Converters (ADC) Part Context

The AS1530 belongs to a family of low-power, single-supply A/D converters that includes the AS1531 variant. While the AS1530 operates at 400ksps with a +4.5V to +5.5V supply, the AS1531 provides 300ksps performance on a +2.7V to +3.6V supply. Both share identical pinouts, channel counts, and architectural features, differing primarily in voltage tolerance and maximum sampling speed.

Analog To Digital Converters (ADC) Replacement Considerations

The AS1531 is a functional substitute within the same series but requires a lower supply voltage (+2.7V to +3.6V) and offers a reduced sampling rate of 300ksps. Verify that the system design can accommodate the lower voltage rail and that the 300ksps throughput meets application timing constraints before substitution.
