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.
