ULS24 - 1

ULS24 Product Brief Product overview The Anitoa ULS24 is an ultra-low-light CMOS image sensor. Its low cost, small form factor and high level of integration make it optimally suited for use in a portable device in medical, scientific and industrial applications. An example of such application is a field portable nucleic-acid-test (NAT) system that performs molecular sensing based-on fluorescence or chemiluminescence signaling principles. ULS24 is built on 0.18um CMOS process at a world-leader specialty semiconductor foundry. Pixel array Pixel Ctrlr Figure 1. ULS24 Chip Application Block Diagram Features - Ultra low-light sensitivity. Detection threshold ~3.0 x 10-6 lux. - Low dark current, high SnR (>13dB at detection threshold). - 12-bit ADC. Dual gain mode. - Wide dynamic range (> 85dB). Excellent linearity (<0.6%). - Digital interface through Serial Peripheral Interface (SPI). - Built-in junction temperature sensor. - 3.3V and 1.8V power supply, 30mW max power. - Operating temperature range -15 °C - 85 “C1. 1 The image sensor can meet noise spec at junction temperature up to 55 °C.
