Benefits

512-channel in a 23 x 15 mm² FBGA package

Ultra-low noise of 0.29 fC at 0.5 μA input current in low noise mode

Lowest power dissipation of 1.25 mW per channel in low power mode

Adjustable integration time down to 51 μs (20 kSPS) at 20-bit resolution. Up to 26-bit at integration times of 1 ms

Zero biased photodiodes (true ground concept) for ultra-low dark currents

Integral linearity of ±0.080% of reading and ±0.2 ppm of full-scale range (all channels active)

Automatic zero offset calibration, input charge calibration and linearity calibration

Features

No external components required. Integrated capacitors for supply and reference decoupling

No charge loss. Continuous charge integration due to zero dead time of ADC architecture

Selectable full-scale range of 0.5 μA in low range and 1 μA in high range

Adjustable full-scale range, integration time and power consumption via SPI interface as well as adjustable output modes via LVDS

Selectable power supply concept between dual ±1.5 V analog supply (true ground concept) or single +3.0 V analog supply

On-chip LDOs, voltage references and temperature sensor

Built-in diagnostic modes for testing full detector signal chain
