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

Simultaneous Sampling

ANALOG-TO-DIGITAL CONVERTER

DESCRIPTION

FEATURES

The ADS7862 is a dual 12-bit, 500kHz analog-to-

digital converter (A/D) with 4 fully differential input

channels grouped into two pairs for high speed simulta-

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

amplifiers are fully differential and are maintained dif-

ferential 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

● PARALLEL INTERFACE

● 1MHz EFFECTIVE SAMPLING RATE

● LOW POWER: 40mW

The ADS7862 offers parallel interface and control in-

puts to minimize software overhead. The output data for

each channel is available as a 12-bit word. The ADS7862

is offered in an TQFP-32 package and is full specified

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

APPLICATIONS

● MOTOR CONTROL

● MULTI-AXIS POSITIONING SYSTEMS

● 3-PHASE POWER CONTROL
