AS1526-BSOT

Analog To Digital Converters (ADC) Overview

The AS1526-BSOT is a 10-bit, single-supply analog-to-digital converter (ADC) from ams-OSRAM USA INC. It operates on a 2.7V to 3.6V supply and achieves a throughput rate of 73ksps with a conversion time of 7.5µs. The device integrates a successive-approximation register (SAR), an internal track/hold amplifier, and an internal 2.5V reference. Power consumption is 4mW at maximum sampling speed, dropping to 1µW in shutdown mode. Data is accessed via a standard 3-wire serial interface compatible with SPI, QSPI, and Microwire protocols.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BSOT' against the manufacturer's official ordering information to confirm the exact packaging variant and tape-and-reel specifications. Ensure the component source matches the original manufacturer or authorized distributors to guarantee authenticity and compliance with the specified electrical characteristics.

Analog To Digital Converters (ADC) Selection Notes

Select the AS1526 when an integrated internal 2.5V reference is required for simplified design. Choose this model for applications demanding low power consumption under a single supply voltage. Consider the AS1527 if an external reference is preferred to potentially reduce power usage further. Ensure the system supports the required 3-wire serial interface timing constraints.

Analog To Digital Converters (ADC) Part Context

The AS1526 is part of the AS1526/AS1527 family of low-power, 10-bit A/D converters designed by ams-OSRAM (formerly austriamicrosystems). These devices are engineered for space-limited applications requiring high reliability and robust performance in battery-powered environments. The series utilizes a successive-approximation architecture to deliver accurate digital conversions from analog inputs.

Analog To Digital Converters (ADC) Replacement Considerations

The AS1527 is a direct functional alternative within the same family, differing primarily by the requirement for an external reference voltage instead of an internal one. Both share identical pinouts, resolution, and interface protocols.
