Preliminary Technical Data
AD7641
CIRCUIT INFORMATION
The AD7641 is a very fast, low-power, single-supply, precise 18-
bit analog-to-digital converter (ADC) using successive
approximation architecture.
Rev. Pr E | Page 11 of 24
The AD7641 features different modes to optimize performances
according to the applications. In Warp mode, the AD7641 is
capable of converting 2,000,000 samples per second (2 MSPS).
The AD7641 provides the user with an on-chip track/hold,
successive approximation ADC that does not exhibit any
pipeline or latency, making it ideal for multiple multiplexed
channel applications.
The AD7641 can be operated from a single 2.5 V supply and be
interfaced to either 5 V or 3.3 V or 2.5 V digital logic. It is
housed in a 48-lead LQFP or a tiny LFCSP packages that
combines space savings and allows flexible configurations as
either serial or parallel interface. The AD7641 is a pin-to-pin-
compatible upgrade of the AD7674.
