ADS7861

Dual, 500kHz, 12-Bit, 2 + 2 Channel,

Simultaneous Sampling

ANALOG-TO-DIGITAL CONVERTER

DESCRIPTION

FEATURES

The ADS7861 is a dual, 12-bit, 500kHz, analog-to-

digital converter with 4 fully differential input channels

grouped into two pairs for high speed, simultaneous

signal acquisition. Inputs to the sample-and-hold ampli-

fiers are fully differential and are maintained differen-

tial 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.

● 4 INPUT CHANNELS

● FULLY DIFFERENTIAL INPUTS

● 2µs TOTAL THROUGHPUT PER CHANNEL

● GUARANTEED NO MISSING CODES

● 1MHz EFFECTIVE SAMPLING RATE

● LOW POWER: 40mW

● SSI SERIAL INTERFACE

The ADS7861 offers a high speed, dual serial interface

and control inputs to minimize software overhead. The

output data for each channel is available as a 12-bit

word. The ADS7861 is offered in a 24-lead SSOP

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
