The aLFA-C is a programmable interfacing ASIC designed specifically for space-borne infrared ROICs and other image sensors. It significantly reduces the need for traditional front-end electronics by integrating essential functions onto a single chip. A standout feature includes its capability to operate with a single unregulated supply, aided by on-chip LDOs and regulators.
aLFA-C offers extensive programmability, including a fully programmable sequencer for ROIC interfacing, and supports various digital output configurations such as CMOS, LVDS, or CML. It includes SPI interfaces for seamless image sensor integration and features analog acquisition over multiple channels, with high precision 16-bit ADCs, allowing parallel or interleave configuration for flexible data handling speeds.
This ASIC is equipped with several measurement capabilities for resistance, voltage, and current, and provides programmable voltage and current sources. With resilience against TID, SEU, and SEL, it's highly reliable in harsh space environments. It's operational over a wide temperature range from 35K to 330K, suitable for varied applications in extreme conditions.
