12-Bit High Speed Low Power Sampling

ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● 500kHz THROUGHPUT RATE

● 2.5V INTERNAL REFERENCE

● LOW POWER: 11mW

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.

● SINGLE SUPPLY +5V OPERATION

● DIFFERENTIAL INPUT

● SERIAL INTERFACE

● GUARANTEED NO MISSING CODES

● MINI-DIP-8 AND MSOP-8

● UNIPOLAR INPUT RANGE

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.
