DESCRIPTION
The ADS7818 is a 12-bit sampling analog-to-digital
converter (A/D) complete with sample/hold, internal
2.5V reference, and synchronous serial interface. Typi-
cal power dissipation is 11mW at a 500kHz through-
put rate. The device can be placed into a power down
mode which reduces dissipation to just 2.5mW. The
input range is zero to two times the reference voltage,
and the internal reference can be overdriven by an
external voltage.
Low power, small size, and high-speed make the
ADS7818 ideal for battery operated systems such as
wireless communication devices, portable multi-chan-
nel data loggers, and spectrum analyzers. The serial
interface also provides low-cost isolation for remote
data acquisition. The ADS7818 is available in a plas-
tic mini-DIP-8 or an MSOP-8 package and is guaran-
teed over the –40 C to +85 C temperature range.
