AD7466/AD7467/AD7468

GENERAL DESCRIPTION
The AD7466/AD7467/AD7468 are 12/10/8-bit, high
speed, low power, successive-approximation ADCs respectively.
The parts operate from a single 1.8 V to 3.6 V
power supply and feature throughput rates up to 100
kSPS. The parts contain a low-noise, wide bandwidth
track/hold amplifier which can handle input frequencies in
excess of 100 kHz.
The conversion process and data acquisition are controlled
using CS and the serial clock, allowing the devices to
interface with microprocessors or DSPs. The input signal
is sampled on the falling edge of CS and the conversion is
also initiated at this point. There are no pipelined delays
associated with the part.
The AD7466/AD7467/AD7468 use advanced design techniques
to achieve very low power dissipation at high
throughput rates.
The reference for the part is taken internally from VDD.
This allows the widest dynamic input range to the ADC.
Thus the analog input range for the part is 0 to VDD. The
conversion rate is determined by the SCLK.
