ADVANCE INFORMATION
OPT 0256C
The IC is manufactured in a standard CMOS process with some additional steps for defining the broad spectral range photodiodes. Fig. 11 shows a functional block diagram of the OPT 0256C PDA IC. Test circuitry is not shown. Four different operation modes are possible: Continuous Mode External Start Mode External Start/stop Mode Hold Mode
Photo Detector Array IC 1. Introduction The OPT 0256C is a 256-channel PDA (photo detector array) IC with all-digital I/O. The PDA consists of 256 photodiodes each having its own 16-bit ADC, an analog biasing circuit with integrated bandgap voltage reference, a settable accumulation counter for wide accumulation range, a temperature sensor with ADC and a digital control block with Motorola SPI-compatible serial interface.
