FEATURES
▪ Conversion of 4 sensor signals of photodiodes
(e.g. RGB/XYZ color plus one blank channel for
compensation of parasitic currents or tempera-
ture conversion) or other sensors with current
signal output
▪ Configurable conversion gain and integration
time supports a very high dynamic range of
1 – 2.68E+08
▪ Up to 16 bit (internal 20 bit) signal resolution
by achievable sensitivity up to 20 fA/LSB –
scaling (by a divider) the internal 20 bit on
16 bit output
▪ Adjustable operation modes like continuous, by
command and externally synchronized (by
given start and start/end signal) measurement
▪ Option: external control of integration time and
reference current (gain)
▪ High linearity of amplifying, no cross talking
▪ High absolute accuracy without additional
sources
▪ High reliability internal reference source gener-
ation
▪ Consideration of negative offset
▪ Measurement of current for both polarities
▪ Measurement of integration time
▪ Supply and temperature independent response
▪ Insensitive to 50 Hz/60 Hz external disturb-
ances
▪ 16 Bit/400 kHz fast I²C interface with pro-
grammable slave addresses
▪ Very low current consumption in active, in
Power down and Standby mode
▪ Supply voltage 2.7 V to 3.6 V
▪ Temperature range -40°C to 125°C
▪ Deliverable in SMD package and as bare die
APPLICATIONS
▪ Precise conversion of average e.g. integral
photo current for optical sensors and arrays
(e.g. UV, VIS, IR) and other sensors with cur-
rent output
▪ In combination with ams Sensors Germany’s
color sensors: measurement of lights – chro-
maticity coordinates (XYZ CIE 1931, DIN 5033
and similar) or color temperatures to control
and process displays and backlights (e.g. LED,
CCFL)
▪ In combination with ams Sensors Germany’s
color and spectral sensors: measurement of re-
flective and/or transmitted light – chromaticity
coordinates (XYZ CIE1931, DIN5033 and simi-
lar) measurement of objects and surfaces for
analyzes, quality management, sorting, etc.
