Analog-digital converter EV12AS200

The EV12AS200 is a 12-bit 1.5 GSps ADC. The device includes a front-end Track and Hold stage (T/H), followed by an analog encoding stage (Analog Quantizer) which outputs analog residues resulting from analog quantization. Successive banks of latches regenerate the analog residues into logical levels before entering an error correction circuitry and a resynchronization stage followed by a DEMUX with 100Ω differential output buffers. It integrates 3 Wire Serial Interface (3WSI) circuit (write only), which can be activated or deactivated (via Mode signal). Main functions accessed via the 3WSI can also be accessed by hardware (OA, GA, SDA, SDAEN_n, TM_n, RS pin).
