AS1529-BTDR

Analog To Digital Converters (ADC) Overview

The AS1529-BTDR is a low-power, 10-bit analog-to-digital converter (ADC) manufactured by ams-OSRAM USA INC. It employs a successive-approximation register (SAR) architecture and operates on a single supply voltage ranging from +2.7V to +5.25V. The device features two single-ended input channels with an input common-mode range extending from GND to VDD. It supports a maximum sampling rate of 150ksps while consuming only 350µA at full speed. Power consumption is significantly reduced via automatic shutdown between conversions, drawing less than 0.2µA in standby. Data access is facilitated through a high-speed, SPI-/QSPI-/MICROWIRE-compatible 3-wire serial interface.

Analog To Digital Converters (ADC) Feature Summary

• 10-bit SAR ADC with 150ksps maximum sampling rate
• Two single-ended analog input channels
• Automatic shutdown mode reduces current to <0.2µA
• 3-wire SPI/QSPI/MICROWIRE compatible serial interface

Analog To Digital Converters (ADC) Applications

• Portable battery-powered data-acquisition systems
• Remote sensor interfaces
• Data logging devices
• Lab instruments requiring space-limited A/D conversion

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'BTDR' against the manufacturer's official documentation to confirm package type and reel specifications. Confirm availability status as older product lines may have limited stock or end-of-life status. Ensure the supplier provides valid traceability documents for the component batch.

Analog To Digital Converters (ADC) Selection Notes

Select the AS1529-BTDR when dual single-ended inputs are required within a compact footprint. This model is suitable for applications needing fast wakeup times of 1.4µs and low power consumption at varying throughput rates. Ensure the external reference voltage falls within the specified range of +1V to VDD + 50mV for optimal performance.

Analog To Digital Converters (ADC) Part Context

The AS1529 is part of the AS1528/AS1529 family of micro-power ADCs. While the AS1528 offers true differential inputs and software-configurable unipolar/bipolar modes, the AS1529 is specifically designed for two-channel single-ended applications. Both share identical power characteristics, interface protocols, and the 8-pin TDFN (3x3mm) package.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers for the AS1529-BTDR are not available in the provided source material. Evaluate other 10-bit SAR ADCs with similar pinouts and power profiles if direct replacement is necessary.
