AS1525-BTDT

Analog To Digital Converters (ADC) Overview

The AS1525-BTDT is a low-power, 12-bit analog-to-digital converter (ADC) featuring two single-ended input channels. It utilizes a successive-approximation register (SAR) architecture and operates on a single supply voltage ranging from +2.7V to +5.25V. The device supports a maximum sampling rate of 150ksps with an internal conversion clock. Power consumption varies from 350µA at full speed down to 200nA in automatic shutdown mode between conversions. Data access is facilitated via a high-speed, SPI-/QSPI-/MICROWIRE-compatible 3-wire serial interface.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BTDT' against the manufacturer's official ordering information to confirm package type, tape-and-reel specifications, and regional availability. Ensure the source document explicitly lists this exact part number variant rather than the generic AS1525 family designation.

Analog To Digital Converters (ADC) Selection Notes

Select the AS1525-BTDT when dual single-ended inputs are required instead of the pseudo-differential or true-differential configuration offered by the AS1524. Confirm that the application requires a unipolar input range (0 to VREF) and that the system can accommodate the 8-pin TDFN (3x3mm) package constraints.

Analog To Digital Converters (ADC) Part Context

The AS1525 is part of the AS1524/AS1525 family of 12-bit SAR ADCs manufactured by ams-OSRAM USA INC. (formerly austriamicrosystems). While the AS1524 offers configurable differential/single-ended inputs, the AS1525 is specifically designed for applications needing two independent single-ended channels with identical performance characteristics regarding power and speed.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-model comparison within the same family indicates the AS1524 as a functional alternative if differential input capability is acceptable.
