12-Bit, High-Speed, Low Power Sampling

ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● 500kHz THROUGHPUT RATE

● 2.5V INTERNAL REFERENCE

● LOW POWER: 17.5mW

● SINGLE SUPPLY +5V OPERATION

● SERIAL INTERFACE

The ADS7835 is a 12-bit, sampling analog-to-digi-

tal 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 dis-

sipation to just 2.5mW. The input range is –V_REFto

+V_REF, and the internal reference can be overdriven

by an external voltage.

● GUARANTEED NO MISSING CODES

● MSOP-8

● ±V_REFINPUT RANGE

Low power, small size, and high speed make the

ADS7835 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 ADS7835 is avail-

able in an MSOP-8 package and is guaranteed over

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