ADS7864

500kHz, 12-Bit, 6-Channel

Simultaneous Sampling

ANALOG-TO-DIGITAL CONVERTER

DESCRIPTION

FEATURES

The ADS7864 is a dual 12-bit, 500kHz Analog-to-

Digital (A/D) converter with 6 fully differential input

channels grouped into three pairs for high speed simul-

taneous signal acquisition. Inputs to the sample-and-

hold amplifiers are fully differential and are main-

tained differential to the input of the A/D converter.

This provides excellent common-mode rejection of

80dB at 50kHz which is important in high noise

environments.

● 6 SIMULTANEOUS SAMPLING CHANNELS

● FULLY DIFFERENTIAL INPUTS

● 2µs TOTAL THROUGHPUT PER CHANNEL

● GUARANTEED NO MISSING CODES

● PARALLEL INTERFACE

● 1MHz EFFECTIVE SAMPLING RATE

● LOW POWER: 50mW

● 6X FIFO

The ADS7864 offers a parallel interface and control

inputs to minimize software overhead. The output data

for each channel is available as a 16-bit word (address

and data). The ADS7864 is offered in a TQFP-48

package and is fully specified over the –40°C to +85°C

operating range.

APPLICATIONS

● MOTOR CONTROL

● MULTI-AXIS POSITIONING SYSTEMS

● 3-PHASE POWER CONTROL
