DESCRIPTION
The ADS7835 is a 12-bit, sampling analog-to-digital
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 dissipation
to just 2.5mW. The input range is –VREF 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 multichannel
data loggers, and spectrum analyzers. The
serial interface also provides low cost isolation for
remote data acquisition. The ADS7835 is available
in an MSOP-8 package and is guaranteed over
the –40°C to +85°C temperature range.
