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. The AD9203 has an onboard programmable reference. An external reference can also be chosen to suit the dc accuracy and temperature drift requirements of an application. An external resistor can be used to reduce power consumption when operatin……
