92543L10

GENERAL DESCRIPTION

The AD9254 is a monolithic, single 1.8 V supply, 14-bit, 150 MSPS analog-to- digital converter (ADC), featuring a high performance sample-and-hold amplifier (SHA) and on-chip voltage reference. The product uses a multistage differential pipeline architecture with output error correction logic to provide 14-bit accuracy at 150 MSPS data rates and guarantees no missing codes over the full operating temperature range.
