GENERAL DESCRIPTION

The AD9203 is a monolithic low power, single supply, 10-bit, 40 MSPS analog-to-digital converter, with an on-chip voltage reference. The AD9203 uses a multistage differential pipeline architecture and guarantees no missing codes over the full operating temperature range. Its input range may be adjusted between 1 V and 2 V p-p.
