DESCRIPTION
The ADS7835 is a 12-bit, sampling analog-to-digi-
tal converter (A/D) complete with sample-and-hold
(S/H), internal 2.5V reference, and synchronous
serial interface. Typical power dissipation is 17.5mW
at a 500kHz throughput rate. The device can be
placed into a power-down mode which reduces dis-
sipation to just 2.5mW. The input range is âVREF to
+VREF, and the internal reference can be overdriven
by an external voltage.
Low power, small size, and high speed make the
ADS7835 ideal for battery-operated systems such
as wireless communication devices, portable multi-
channel data loggers, and spectrum analyzers. The
serial interface also provides low cost isolation for
remote data acquisition. The ADS7835 is avail-
able in an MSOP-8 package and is guaranteed over
the â40°C to +85°C temperature range.
