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. Typical

power dissipation is 11mW 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 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-channel

data loggers, and spectrum analyzers. The serial

interface also provides low-cost isolation for remote

data acquisition. The ADS7818 is available in a plastic

mini-DIP-8 or an MSOP-8 package and is guaranteed

over the –40°C to +85°C temperature range.
