AS89000 Transimpedance-Amplifier
AS89000
The AS89000-devices are a family of integrated circuits of programmable gain transimpedance amplifiers with 4 channels per IC (more custom specific, on request).
The AS89000-devices are mainly used for signal conditioning of sensors with current outputs. They are especially suitable for connection of photodiodes of array and row sensors. The possibility to adjust the transimpedance in 8 stages is a special feature. The adjustment is made by programming three pins and is valid for all channels together. The device packages (naked chip on request) are RoHS conform and optimized for COB- mounting and SMD.

AS89020 Converter with digital output
AS89020
The AS89020 is a 12-bit, 4-channel, current input Analog-to-Digital Converter (ADC). It combines current-to-voltage (TIA) and analog-to-digital (AD) conversion, so that 4 separate current output devices (e.g. photodiodes) can be directly connected to its inputs and digitized.
For each of the 4 inputs the AS89020 provides an input amplifier with a track and hold circuit. The outputs of the track and hold stages are serial converted to 12-bit digital words using an analog-to-digital converter (ADC).

AS73211 - JENCOLOR® Digital XYZ Sensor
AS73211
The AS73211 is a digital XYZ sensor with I2C interface for relative and absolute color measurement and control. The combination of True Color XYZ sensitized photodiodes with a filter function based on the standard CIE 1931/DIN 5033 (human eye perception) and used interference filter technology as leading and most accurate technology of three-range sensors makes the AS73211 more accurate than RGB sensors and guarantee this function without spectral changings over lifetime. The AS73211 is designed with a high dynamic range to measure any light in the visible range (VIS) in environments from sunlight to dark rooms, dimmed LEDs, or dark colored monitors.
