PART DESCRIPTION
This data sheet describ
es the evaluation board for the AD7262
and the AD7264, which are dual, 12-bit/14-bit, high speed, low
power, successive approximation analog-to-digital (ADCs). The
parts operate from a single 5 V power supply and feature through-
put rates up to 1 MSPS per on-chip ADC. Two complete ADC
functions allow simultaneous sampling and conversion of two
channels. Both devices contains two ADCs, each preceded by a
power, successive approximation analog-to-digital (ADCs). The
parts operate from a single 5 V power supply and feature through-
put rates up to 1 MSPS per on-chip ADC. Two complete ADC
functions allow simultaneous sampling and conversion of two
channels. Both devices contains two ADCs, each preceded by a
true differential analog input with a PGA. There are fourteen gain
settings available, ×1, ×2, ×3, ×4,
settings available, ×1, ×2, ×3, ×4,
×6, ×8, ×12, ×16, ×24, ×32, ×48,
×64, ×96, and ×128. In addition, the AD7264 and AD7262 contain
four comparators. Full details on the AD7262 and AD7264 are
available in the AD7262 and AD7264 data sheets available from
Analog Devices, Inc., which should be consulted in conjunction
with this data sheet when using the evaluation board.
