CIRCUIT INFORMATION
The AD7910/AD7920 are fast, micropower, 10-bit/12-bit,
single-supply A/D converters, respectively. The parts can be
operated from a 2.35 V to 5.25 V supply. When operated from
either a 5 V supply or a 3 V supply, the AD7910/AD7920 are
capable of throughput rates of 250 kSPS when provided with a
5 MHz clock.
The AD7910/AD7920 provide the user with an on-chip track-
and-hold, A/D converter, and a serial interface housed in a tiny
6-lead SC70 package or 8-lead MSOP package, which offers the
user considerable space saving advantages over alternative
solutions.

The serial clock input accesses data from the part but also
provides the clock source for the successive approximation A/D
converter. The analog input range is 0 V to V
reference is not required for the ADC and there is no reference
on-chip. The reference for the AD7910/AD7920 is derived from
the power supply and thus gives the widest dynamic input
range.
The AD7910/AD7920 also feature a power-down option to
allow power saving between conversions. The power-down
feature is implemented across the standard serial interface, as
described in the Modes of Operation section.
