AS8512-ZSSP SSOP20 LF T&RDP

Overview

The AS8512-ZSSP is a specialized data acquisition device designed for battery sensor applications, manufactured by ams-OSRAM USA INC. It integrates two high-resolution 16-bit Sigma-Delta analog-to-digital converters (ADCs) on a single chip to monitor battery pack parameters. The component supports programmable sampling rates ranging from less than 1 Hz up to 8 kHz, allowing for flexible data throughput configurations. It features zero offset characteristics for both channels to ensure measurement accuracy. The device operates with a 3.3 V supply voltage and is housed in an SSOP-20 package suitable for surface mount technology.

Feature Summary

• Dual-channel architecture with integrated 16-bit Sigma-Delta ADCs for simultaneous current, voltage, and temperature sensing
• Configurable sampling frequency enabling data throughputs from sub-Hertz levels to 8 kHz
• Zero-offset design for both signal channels to maintain precision without external calibration

Applications

• Battery pack monitoring systems
• Electric vehicle (EV) battery management
• Hybrid electric vehicle powertrain sensors

Procurement Notes

Verify the specific suffix ZSSP against official datasheets to confirm pinout and packaging details. Ensure compatibility with the target system's 3.3 V logic levels and I/O requirements. Check for moisture sensitivity classification prior to soldering. Confirm end-of-life status or availability constraints through authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when dual-channel high-precision acquisition is required for battery cells. The 16-bit resolution provides sufficient granularity for state-of-charge calculations. Consider the maximum 8 kHz sampling rate against processing capabilities of the host microcontroller. Verify that the SSOP-20 footprint fits the printed circuit board layout constraints.
